SUNGOLDPOWER 6000W Pure Sine Split-Phase Inverter, Review & Testing

[@fisherus]

You do a very good in-depth job in your videos and that's why I like watching them. I wish that each of you, who make this type of video would explain the acronyms they use for the common layman in terms that are understandable. Most of the viewership is ignorant of the acronyms you are using and need to know about them if they are to learn. Thanks again, for another great video.

[@LithiumSolar]

Thank you. You're right - I need to keep this in mind and try to explain better. I think it's mostly because I end up worry about the video being too long that I leave things out and/or cutting too much. I'll try to expand on the acronyms in the next video :)

I got a tip to add to your testing setup use those rotating style DC shutoffs and wire in your resistor across both terminals so when the switch is off the resistor is connected then you can just plug in your Anderson connector with the switch off and it connects the resistor automatically that you can just flip the switch on for testing

[@montwell2]

I've had the 24v 4000w model for over a year, running low loads 24/7, and occasional high loads like a well pump, with no issues. I leave it in standby mode, which only consumes about 18w. It switches on when about 25w or greater load is sensed on the output.

(Note that L1 and L2 are limited to half the total rated watts each, so for my 4,000w model I don't exceed 2,000 watts on each 120v leg (at least not for a longer time than the specified "surge" time that is allowed) ).

I confirmed last month that the surge rating on this inverter is no joke. I fired up my 20,000 watt surround sound audio system and played at levels sufficient to bring down a section of my ceiling. Yeah, it handled it. No doubt I hit peaks over 14kW input power to the amplifier racks.

[@GordLamb]

Excellent review and presentation, like always! One thing I'd suggest: should (almost) always connect the positive side of negative/ground bonded DC circuits first. That way if you do accidentally contact the chassis with the other lead, there's no risk of a short. I'm sure you already know this, but my anxiety went up a little bit during the capacitor charging. :)

That's a great tip to keep in mind!

[@nathans3022]

Well, I purchased a Sigineer 6000W Split phase inverter... and it arrived damaged. Took a pretty good hit to the DC input side and pushed the rear panel in against the internal PCB. So looks like my review of the 24V version of the unit you reviewed here will have to wait. If UPS approves the damage claim and UPS doesn't want the inverter, I'll pull apart that one for the review. Thanks for doing this in depth review of the 48V version. The internal view and the quality of the wiring and assembly sold me on this manufacturer. I just didn't need a 48V system and in the event I ever need emergency juice I can just run 2x 12V AGM batteries in series to get 24V to run it vs needing 4. Plus, I will only really need 3000-3500W max typical for my needs currently so the 3,000W version was out and the next step up was the 6000W version. lol

[@riftvalley1765]

This inverter is actually the 6kw Sigineer-Power inverter someone stamped the sun gold on it, I have one that's connected to my 800Ah battery bank running water well, hybrid 50gal water heater & 12000BTU mini split AC, I really like this inverter over any other ones on market.

[@LithiumSolar]

Do you have any evidence that this is a Sigineer inverter? Sun Gold Power has told me that they are not in any way affiliated with Sigineer.

[@eddietee6305]

It doesn't have to utilize an auto-transformer to "create" a neutral, a regular 2-winding isolation transformer can accomplish the same thing with a center tap secondary winding. The latter is a more safer way to create a neutral. Costs more that way too.

[@LithiumSolar]

Yes, a regular 2-winding isolation transformer can accomplish the same thing - but that's not how this is wired here.

[@xunil76]

so who else took one look at that inverter and had a flashback to the Phoenix Gold/Orion/Soundstream mega-kW competition car audio amplifiers from the early 90's? you know, the ones that were "rated" at like 400w at 4Ω, but would push something ridiculous like 3kW - 4kW into a 0.125Ω load so they could compete (and dominate) in the lower-wattage classes...ah, the good 'ol days....LOL

[@wesleyofficer1237]

Wow to see an inverter trip LBCO before the BMS cut off brought a smile to my face! 😃 This definitely LOOKS like the old AIMSPOWER unit, but it obviously has some charge profiles on their that the old AIMSPOWER version did not have.

[@j.p.5716]

I have this exact Inverter and have been testing it (real world) for about 4 months now. I currently have it hooked up to about 350Ah of Homemade 48V 18650 Packs (500Ah after this weekend) with about 8kW of Panels on the roof flowing through (2) Sunnysky Solar MPPT 60A Solar Charge Controllers (which are working great so far). I also have it connected to the Grid. I have it set to use the battery as priority and the Internal Charger turned off. If the battery goes below a certain point, it is supposed to switch to the Grid power and then switch back after the battery it is charged back up but I have had some issues with this functionality. I am currently working with SunGold (via emails) trying to figure it out but no resolution yet. The first problem that I experienced is that from time to time (with no rhyme or reason that I can see) it will switch off of battery power to grid power and then a few minutes later back to the battery. I have seen it do this as many as three times in a three hour time span when the battery was at 90% charge and the inverter at only 50% capacity. SunGold did not have an explanation for this but asked me to video tape it happening for them. The second issue I had is that one Saturday when I arrived just after daylight and the Inverter was on Grid power. The Battery was at 46V (around 60% capacity) and just started charging for the day. I waited for over an hour and but it never did switch back to battery power. When I finally switched the Inverter off and then back on it immediately went to Inverter (battery) mode. SunGold did not have an explanation for this either. Those issues are not as concerning as the third issue that I had. This set-up is in a building that I normally only go and visit on the weekends but about a month ago my wife had the need to go up there on a Wed. and when she opened the door to the building there was no power whatsoever. She called me and I had her go and flip the master switch to turn the building back on the Grid (totally bypassing the PV system) so she could do what she needed to do. Apparently the building had been without power for a couple of days as the freezers we have there were almost thawed out. Luckily we do not have much in them right now as I try and get the bugs worked out of the system. SunGold has yet to be able to provide me with any answers, the most concerning one is why the system just shut down and did not switch over to the Grid power. Since I was not up there that Wednesday, I was not able to observe the system. I just had my wife turn all of the switches and breakers off on the DC side as I did not know what had happened. I really do not even know what to do to try and repeat the fault. With all of the lights off in the building, the system just sits there and idles at about 0-10% (one full size fridge, one mini fridge and one chest freezer). Note: I have to leave it in active mode as I could not get Standby mode to work at all. Even when the 1 ton AC unit kicks on (small apt.) it only jumps to about 35% and a month ago it was still not very hot here so I don't even know if the unit had come on that week or not. When I was there last weekend with all of the lights on and running saws and other tools (air compressor) and the A/C in the Apt. kicking on and off everything worked great with zero issues. Even with all of that going on my batteries were at full charge by noon when we left. I was video taping the system trying to catch it tripping off battery to grid but it would not do it on camera. What I do know is that I cannot trust a couple of freezers worth of food to a system that might just shut down for no reason at all. Really wish I could figure it out.

[@mdunbar04]

Wow nothing worst than a system that you can't trust to leave alone. I have (2 ) 24v split phase 3000watt / 6000watt combined Growatt Inverters that I love. I use the same setup you mentioned and it's been working flawlessly.

[@gotnoshoes99]

Most of the idle current is MOSFET gate current and keeping the iron core of the transformer saturated.

[@jimmurphy5355]

A large part is the magnetizing losses in the core. Grain oriented silicon steel laminations lose about 1/2 watts per pound of material when idling at normal operating flux. This loss is independent of the load in the transformer, and dominates the losses at idle. At full power, copper losses due to the resistance of the windings become the bigger portion.

[@shelby9533]

I've enjoyed you information, and am still learning what all the bells and whistles do on my 18K SunGold Inverter

[@richardjeun]

Since your inverter is a source, providing a reference to ground will establish a stability of the neutral to stay fixed to zero volts AC at all times. There many be a bonding wire in that inverter to the neutral wire. The neutral is connected exactly at midpoint of the full coil in the transformer, which puts out 240 V AC, but unless it’s grounded, it will not stay electrically stable. Only voltage that will stay stable without a reference to ground is the 240.

[@peterpetersen6024]

When you add a 100W load, will it add up to 200W consumption with the 100W idle consumption, or will it be less? If less the 100W idle consumption will not be such a pain as it looks at first sight.

[@eddietee6305]

It will add to your regular load, can't get away from it.

[@eksine]

I saw the same loose studs on my Amazon warehouse (customer return) samlex PST 1500-12v inverter, I thought it was broken too but you just confirmed it's a design on purpose

[@jessenester1760]

Correct. Just like isolation transformers, and the step down transformers at the service pole outside your house. The center tap of the transformer is your neutral. Yes, the 240 in to that unit creates that neutral on it's secondary output.

[@nathans3022]

Hoping you see this, as I am kinda stumped. This is the same inverter just re-branded as the Sigineer 6,000W model based on what I have seen of the internals and comparing it to my Sigineer. The question I have relates to your AC OUTPUT wiring. I have the same panel you have and am preparing to run lines to it. I do not ever plan on having an AC Input either. This will just be stand-alone, off grid. So my question relates to bonding the neutral and ground on this type of setup. Sigineer has kind of mixed messages regarding it, namely on removing the bonding screw. I guess what I am asking, How would you wire up this inverter in a stand-alone setup with no AC-Input to power a small house using the same panel you have in this video? As is expected- If I fry myself, it is my fault entirely. I am just looking for some advice on wiring it up. I am comfortable around AC wiring, just don't wanna screw up the inverter. lol

[@LithiumSolar]

My Opinion) The neutral+ground bond should only occur at one location. Anything more turns the ground wire to a current-carrying conductor (very bad). If you're running it completely off-grid like I am (with no AC input ever), you would wire your inverter output to a breaker panel, then bond there. That's how I wired it in this video and how I have my AIMS 10kW wired. Official Answer) Contact an electrician ;)

[@nathans3022]

@@LithiumSolar Do you have your AIMS chassis grounded to Earth? I actually need to open mine back up and see because I never noticed if they had bonded the ground inside the inverter. Some do that and some don't. Thank you for reading and replying. :-) I actually live next door to an electrician. lol. I was actually planning on asking his opinion on it at some point if I couldn't get the right consensus from others who have done the same things.

[@BecomingOffgrid]

That transformer does appear to have a center tap(so like an auto transformer). That red stuff is Silastic. It would be really awesome to get the part number for that transformer inside. Additionally, those internal wires are probably 90+c rated, so they are probably fine to run those loads. I am pretty sure the manufacturer didn't size the cables to be cool to the touch.

[@matthewknight5641]

I just bought the 24 volt model exactly like that. It seems to be nice so far. I think it's only 2000 watts per leg tho. I was kinda hoping for it to be more capable but it does power up a 15000 but ac on my camper

I have this same unit for a year and a half now. I use the hell out of it, well pump, compressors, 3hp table saw etc. and have no complaints save for the high idle consumption.

So when running on the genset I have two bonded points. Any thoughts as to how to avoid this?

[@lesw8798]

I removed the bonding wire off my honda 3500 for use with my furnace otherwise the computer on the furnace gives a ground fault and won’t turn on during a power failure. Then i made a plug with the neutral and ground connected and plug it in whenever I use it not hooked up to my transfer switch.

[@Fritz_Schlunder]

@@LithiumSolar Awhile back I purchased both the AIMS 48V input 6000W low frequency 240V/120V output split phase inverter, as well as a SUNGOLDPOWER 48V input 6000W low frequency 240V/120V output split phase inverter. I only just got the SUNGOLDPOWER unit hooked up about five days ago, and have only used it for about 12 hours under 5.4kW output load for electric car charging purposes (plus about 50 hours of idle time with no load). The AIMS and SUNGOLDPOWER seem very similar, but so far, I definitely prefer the SUNGOLDPOWER, for a few important reasons: 1. When I load the AIMS inverter output higher than 18A at 232V AC continuously for more than a few minutes at a time, the unit emits a worrisome burning electrical smell, although it smells fine at or below 18A even when operated at this level for several hours continuously. So far, the SUNGOLDPOWER unit seems to work fine at 22A at 244V AC continuous output (sustained for 6 hours during my first car charging session), although it does currently emit a foul burning Styrofoam smell. The burning Styrofoam smell is no doubt due to actual melting hot Styrofoam, since it gets packaged and shipped in Styrofoam, which tends to break off small pieces that then fall into the unit air intake holes. Then, upon operation, they get really hot and smell bad for awhile, but I expect this smell to eventually go away altogether, once the Styrofoam has finished baking off volatiles. The same burning Styrofoam smell was emitted from the AIMS unit early in it's operational history as well. 2. The AIMS unit cost me roughly $1900 after taxes, while the SUNGOLDPOWER cost me about $1300 after taxes. 3. The SUNGOLDPOWER has a small LCD display that shows input DC voltage (not too accurately though), input AC voltage, and output load in percentage of 6kW rating. The AIMS unit omits this rather valuable feature altogether, thus requiring an external DC power meter, which further increases the effective cost of the system. Overall, so far my impression is that the SUNGOLDPOWER is equivalent or better than the AIMS, especially the price tag and being able to more confidently sustain operation at its full power rating. Both units however have massive room for technical improvement, as they both lack proper 0.1V accurate configurability for charging voltage and low voltage cut-off, for safe use with various types of lithium ion batteries available today. They also both consume vastly excessive idle quiescent current, and have much too low overall efficiency under load (both rated around 88%). If they improved the efficiency from say 88% to 93%, this would effectively shrink the required battery bank of the solar system by about 5%, and simultaneously increase the "effective size" of the solar array by about 5%. For a $30k solar array + battery based system, this equates to a savings of $1500 on the overall system, which would easily justify paying over $500 more for the inverter (say if they doubled up the MOSFETs and improved the transformer, so as to get better efficiency - along with better overload capability). They should also improve the inverters to allow paralleling of multiple units, as a standard feature. Ideally, this would become a standard feature on all inverters from all manufacturers.

[@SamsDIY]

I see you bonded the ground and neutral inside your test breaker box. If the inverter is bonded ground to neutral that would create two paths for current to travel. Just curious about how you have it set up.

Thanks for the video and all the useful info on this channel! I was surprised at the parasitic loss of 100w for just running this inverter.

Then discuss your findings for HD wave, vs. toroidal xformer vs. this style xformer. Anyway foopd for thought as you grow your channel.

[@BrightLights1772]

The Solaredge is a great inverter but it's TOTALLY a different use case. The SE needs optimizers attached to solar panels vs a battery, it's not made for this kind of use. It's intended to be 100% grid-tied, whereas this is more of an off-grid solution that is NOT legal for connection to the grid (you can do it but you need to wire it like a generator and switch yourself off the grid when in use). I actually own both the SolarEdge and this 6K inverter and have tested them extensively.

[@MickeyMishra]

for the quality and for the price of the output this thing as a real bargain! to be completely honest I much rather have a loss of efficiency and have the unit actually be able to put up a power when I need it then worry about it not being as efficient as some other kind of inverter which will usually end up with problems with. this thing looks like a sturdy built product and it doesn't seem like they skipped out on actually building it either. I wonder how clean the AC is from this.?

Nice looking inverter, I would like to have seen you push it more, even my cheap Giandel 4000/8000 inverter can start up an air compressor similar to yours. What it can't start is a 2300w mitre saw which is a crucial tool for a lot of people and has a start up load much higher than an air compressor.

[@LithiumSolar]

Did you watch until the end? I ran a cloths drier on it that pulled 5500W. I would have loved to push it more, just don't have many 6000W appliances lying around AND the batteries were kindof the limiting factor in the test here :) :)

[@reneortiz9572]

The presence of 60 volts between ground and neutral at the inverter outlet can be hazardous to common household appliances, such as refrigerators, etc. Attempting to connect ground to neutral at the inverter outlet will cause internal damage to the power circuits.

Your local electrical codes will dictate how/where the neutral + ground bonding occurs. It is not bonded in the inverter.

I do not understand why big battery sells 175 amp anderson connectors with 6 gauge wire installed in them. I noticed that immediately when I looked into their products. I haven't ordered from them, and I'm sure their batteries are good based on other reviews here on youtube but the 6 gauge wire bothers me. It should be 1 gauge minimum....

[@LithiumSolar]

There are many charts on the Internet that show 200C-insulated wire can hit some pretty high amp ratings. For example, this one www.coonerwire.com/amp-chart/ says it can handle 165A. I agree though and have made the recommendation to them that they consider selling thicker gauge cabling. It sounds like it's possible they'll be carrying more options soon, but I can't speak for them.

You complain about the 'wasted' energy of the inverter/controller when idle. Did you try the power saving mode you mentioned at the beginning of the review? Just curious. On my inverter/controller, when you use the power saving mode, it shuts off the transformer/inverter until you begin to use a device. Thus saving that constant drain. Are you sure you haven't overlooked that feature on your's?

[@LithiumSolar]

Yes it has power saver, no I did not try it. I don't fine that feature particularly useful as you still see pretty much the same self-consumption when a small load is applied. Additionally, my inverter is never off in my home - always something consuming power even if it's just phone or laptop chargers.

Hence...when the system drop to 48 volt..the inverter will switch to main AC. Then when the inverter detect the voltage above 52 volts (battery where charged by a photovoltaic system)...the inverter switch back to battery....Thanks.

[@1rfsam]

I'm a bit late to this video! Thank you, really interesting! I'm considering this inverter right now. How noisy was it under moderate loads? Like 1-2kW.... I know you also have LV6548. Could you compare amounts of noise from LV6548 and this inverter? Assuming that LV6548 runs on battery only (no solar, night conditions and etc.).

[@johndesousa7379]

Looks like the inverter/charger is built good. It had 12 gauge inside which is good for 20 amps at 240 volts. Those inverters are rated for the surge or peak wattage of 6000 watts but I would say they're about 4800 watts continuous. Those batteries are way over rated at 6000 watts. Running the dryer was exceeding the battery cables capacity. All these devices should be rated at their running watts not peak watts. 6000 watts at 48 volts is 125 amps and since you cannot exceed 85% of the cables capacity those batteries should have 1/0 cable. Those batteries are probably only 2400 Running watts each. It looked like the inverter went into self protect on one of the phase at 13:48 time of this video because the dryer was pulling more than it could handle.

Can you use this using receptacle box and connected to 48v battery to charge up Ecoflow Delta Pro automatically?

[@typxxilps]

95 W in idle is a nightmare - 2,4 kWh per day or 876 kWh per year for nothing else than being ready. There must be other solutions than such high current drawer. Having a 8 kWh battery and wasting 2,4 kWh would mean to wast a lot of valueable energy storage, at least at night when everything is coming from the battery.

[@lkeil84]

This would not really be a problem on something such as a boat. You would only turn it on when you needed to run something. Each inverter has a percentage loss. This being 6kw, it is apparently 100 watts. If it was the 24 volt model, it would probably be more and a 12kw model even more. This is why you only get an inverter the size you need. More is not better in this case.

[@3th1xs]

@@lkeil84 my 24v Sungold 6000w inverter ran 100w idle same as this one, but also had an efficiency of about 85% when I measured it using two 1500w heaters on my batteries for 1.5 hours. So 3000w of heaters were actually consuming about 3500w from the batteries. It is supposed to be rated at 88% efficient, and maybe it would get that at 6000w load.

[@VincentsfamilyCali]

I see it cost about the same as the MPP Solare LV6548 ALL in one... is there a reason to get this over the MPP Solar ? thanks

[@LithiumSolar]

MPPSolar products are great as well. The most significant difference will be this is low frequency and the MPPSolar is high frequency. This means the SunGoldPower will have a huge/heavy transformer that allows it to start large inductive loads. The MPPSolar won't have this, won't have as much starting capacity, but will also be more efficient because of not having the transformer. I guess at the end of the day, it comes down to how you plan on using it / what loads you intend to run. If you're running a large air conditioner, welder, well pumps, etc - this may be better suited for you. MPPSolar also has the solar charge controller, which this does not, so you'd have to factor that into the price comparison as well :)

The center tapped secondary is not an auto transformer. It is isolated from the primary, and that makes it simply a transformer.

[@LithiumSolar]

There is no secondary when it's running in pass-through mode.

[@jimmurphy5355]

@@LithiumSolar Nor any primary. In pass through, the incoming line is simply sent to the output through a relay. I haven't taken mine apart to look, but a presume it is a double pole double throw relay that connects the output to the incoming split phase 120/240, or to the center tapped secondary of the big transformer. The primary of the transformer is connected to an H bridge PWM sine wave generator running at the battery voltage. This makes ~ 30 VAC, which is stepped up to line voltage by the transformer, which has a 240 volt secondary with a center tap.

[@user-mt4zr5kp7h]

I didn't see any chokes into the primary. If you add a choke to the primary input, from the transformer into the primary rail, wrap it twice through the core and connect back to the rail. The idle current should drop to about 20 watts.

You mention in this video that you can ground or not ground the neutral based on which inverter you're testing. Have you determined which inverters allow the ground and neutral to be connected? My house was built in 1987 and the utility feed only has three wires... the two hot wires and a combination ground/neutral. I have been having trouble getting the inverter manufacturers to tell me if this is a problem. Sigineer told me that this is not allowed on most of their inverters.

[@shelby9533]

I've been having a similar issue...I have an 18K SunGold inverter..The neutral is not the sam as a ground, I've been told. They do not address this in their setup instructions. I connected the neutral wire to the neutral bar also. What I did, was connect a 2nd ground wire to the original ground and returned it to the main fuse panel. I also connected a physical ground to the square ground terminal with a bare copper wire. triple grounded. extra work, but I know the electricity will have a safe path back to ground this way for sure.

[@ToddDesiato]

The silicone wire insulation is rated to 105C or 120C. At 75C it's not that hot. Of course, the heavier wire would be more efficient. The heat lost on the wire is energy lost from the battery. Also, these LF Inverters are not drawing a nice DC current. The current has a 120Hz ripple that can be rather large at full load. If your average current is 125A, then the peak current is probably 1.414X that value, or 176A. The battery may not be rated for 176A pk currents! That's the major difference between a LF and HF Inverter. The HF inverter has a nice, smooth DC input current, but the LF has a 120Hz, rectified sine dc current. That's why the capacitors eventually fail if not kept cool. If you want to reduce the heat and the ripple current, add a large electrolytic, 200,000 uF capacitor bank between the battery and the inverter.

[@andydelle4509]

I wish these Chinese solar inverter manufactures would build these things to US electrical code, which should be OK for Europe as well. The AC connections should be under a removable cover and a knockout for conduit or other approved AC cable. The DC input terminals should be protected as well. The current there can melt rings and watch bands with little effort. And at least in the USA, if the battery voltage is above 50 volts, it is considered class 1 wiring which should be installed the same as the AC line side.
