Hi Joe no this is a 12k and I asked sol-ark how much watts do I give and they told me I have 8.000 watts but that I have a unbalance the fault it gives me is a G37 BusUnbalance. On 120v. Before I got this one I had a canteen 6048 and Joe it ran everything. Table saw and no problem.they told me to change my saw to 240 and it will work. My compressor is 240v and it's old and the same thing happens. Not to happy. well Don't know what to do so I thought of getting a transformer. Any stay well and safe.

Great inverter, video, and tests!! The design is very similar to AIMS but 10x better with the ability to change settings! I wish some of these LF manufactures could get the idle consumption down a bit though.

[@AveRage_Joe]

Thanks Man! Yeah it seems to be a solid inverter so far! 100% agree if they could figure out a way to lower the idle down!

your great explanation has won me over to Growatt. The units appear to offer great value over a piece by piece build system.

Well thanks Man! I wasnt trying to win or anything like that. Like I said Im not affiliated or anything just like the inverter!😆🤘 It is pretty solid tho!!! Much cheaper in cost compaired to many.

[@aspendell209]

Joe, your audio was excellent. Good to see you still sticking with our old hobby. One thing you want to test on a split-phase inverter is differential wattage between the 2 phases. Older architecture and cheaper inverters have issues if the 2 legs are more than 12-16 Amps AC different from each other. This manifests as an induction motor, or pressurized compressor or deep well pump starts up and draws maybe 30+ amps for a split second. The entire Inverter shuts down. So try just loading 1 phase at 20+ amps (with nothing on other phase) and make sure it stays stable. The ones that shutdown are non-starters for most off-grid type applications. ~cheers & Boom

[@AveRage_Joe]

Thanks Man! I tried to fix and adjust in some places but for the most part was out of my control lol. Oh yeah good point for the 2 phase watt difference!! Ill have to see what I can do for that test. I hope it doesnt have any issues like that!!! Fingers crossed

[@craigcampbell6933]

@@AveRage_Joe How Quickly does the UPS function with Utility power switch under surge current conditions. I ask because I am thinking of using the same Growatt inverter unit to run my 240VAC pool pump (turns on only once a day), and a few other dedicated 240 Services (no in rush), I measured the In Rush current of the pump at 46 Amps, normal run current is about 10 amps. Also thinking of not using batteries, at least until they hopefully become more affordable. Obviously clouds could present an issue however, I ask as It appears that in the near future Net Energy Metering will change, so that you cannot use the Grid as a form of Battery Storage. Anyway just thinking of other options. Thanks

[@AveRage_Joe]

Switch says 10ms for time. Occasionally you may see a flicker with Led lights but not all the time. Yeah you could use this for the pump. You will need a battery. Even if using in the solar function. You could probly just get 4 "junk" lead acid batteries for that. Also may even get by with the 6kw one as the surge is pretty damn high. They are 3X the normal so 36kw for the 12kw inverter and 18kw for the 6kw inverter.

[@bobcole3852]

@@AveRage_Joe do you think you could run whole house on the 6KW unit? Great review, this is the unit I am considering but our consumption is purdy low, like 15kw/day, mostly during the day so direct solar power would cover use. Thanks, love your channel!

[@onegreenev]

Induction cook top need s a pan with water that is designed for induction cook tops. It will do nothing until you put a proper pan on that takes advantage of the induction of the cook top. It will not get hot like a regular resister coil on your regular electric range.

@@AveRage_Joe I was remodeling a 1970's last year and fell broke a hip. At 73 my family convinced me it was time for a change. Then when the hip refused to heal I had a replacement done in December, but in the interim the house sold and I moved to an apt. I've been collecting and processing batteries for several years hoping to follow in your footsteps. Now I am left with about 2700 good cells and thought I'd build them into packs, so still piddling and playing around. Never likely get to build an actual power wall now I suppose. Still enjoy your videos and learning as much as I can... Thanks again Joe for all you do, you are a solid inspiration to this old man!

Well 3 years ago did the big purchase and stock pile of supplies. Then begin this year bought batteries and started our offgrid homestead in June. Well finally getting my pv setup and finishing wiring. So it was nice to see the setup and test. I also have to hook up my generator to system so when batteries are low and no- little sun it will kick on.

Joe, I don’t know if you answer these but I sure could use some helpful guidance and advice so I don’t do anything too crazy. I bought the 12kw growatt after watching your videos. It should be here next week I might need a more detailed video with wiring it completely off grid. I intended to use 12 300w panels total, 6 are in parallel and 6 in series. I have 4 12v Vmax solar 155 batteries and power is being delivered using a #6 Thhn cord. Thanks for making great videos that keep inspiring us to build bigger.

@@AveRage_Joe Yes, I have been off grid for the last 3 years due to my local electric company charging seriously high bills while I was out sailing on deployment. I’m talking over 1000 for one month totaling $5000 in a mostly vacant home with solar panels. I bought a Homegrid 5000 and haven’t looked back. This Growatt is a huge step up and would allow me to run equipment like my dryer finally. My biggest fear is that I will mess this installation up, so I have been obsessing for weeks reading the manual and re watching your videos every night. Any help is a great help, and I’d appreciate if you stopped me from fouling up my installation 😁. Thanks Joe.

[@AveRage_Joe]

Growatt does have quite a few grid-tie inverters to choose from. I have not tried any of them.

[@trevornelmes9331]

Really love what you are doing on this channel. I do notice some things in what your video shows. The first is that the fans are ball bearing fans, and they should last longer, but they are noisier than sleeve bearings. It is a shame (I have not found any at least) that no one makes a fluid dynamic bearing DC axial fan (at least of this size). There are plenty of DC cooling fans for PC cases using such bearings. They last as long as a ball bearing fan, but are way quieter. Your version is split phase (for the US), but they also do a 240V single phase version for Europe. Those block connectors do not look very big. I wonder what your thoughts are on having smaller units paralleled together? It provides redundancy, and wiring can be a smaller gauge (and fit those terminals). My house has a 23kW grid supply (but our night tariff is sooo cheap)! I see that Growatt have just released a 3000W (the SPF 3000T HVM-G2) second generation version of this unit also, which makes me wonder if G3 versions of the bigger ones will appear. It seems to be more efficient from the specs. I also don't like those top fans. I might be inclined to fit a duct over the top and vent that air away sideways, stopping any downward ingress of dust and moisture when the inverter is on standby, and likely also reducing noise a bit.

[@AveRage_Joe]

Thanks Man and thanks for watching!🤘

[@andycanfixit]

Looks good, the efficiency is better than I expected too. The fans are definitely louder than mine but 12kw vs two 3kw units that's probably expected. There is a mode you can choose where it will charge from both solar and utility, you can set the max charge rate from utility as well as the max overall charge rate of both solar and utility combined going into the batteries. Mostly I think that's a mode you'd use while getting ready for a storm to come through to keep everything topped off or if you're using a generator to top off the batteries during low solar input in say an off grid use. Nice handling of the surge from that saw too, looked like your Batrium showed a spike above 7kw for a brief bit, one of the nice things about the low frequency design is the surge handling. Great test, congrats man!

[@AveRage_Joe]

Thanks Man! Yeah eff was better then expected! So I had originally went through all the menu settings and explained them all(kinda) but removed it due to length of video. May do another in future on those. Also I forgot to mention I for some reason cant get the beep to shut off while pushing buttons. Option 15 is off🤷‍♂️. I was also able to change the setting from the online app from a different pc I found out after video🤣

@@AveRage_Joe I've had so many people asking me how to kill that beep, or some other beeps and it must be hit or miss that option 15 works cause on mine with it off no beeps but given all the comments and your experience now too, it doesn't always work. One thing that would be nice as well is if there was a reset to factory default option in the menu too. Overall they work well, its just the little rough edges like that they could stand to fix.

Many calls I've made into Sig Solar either go unanswered, connected with someone who's unable to answer any questions, or messages left and not returned. I suspect they have all the business they want/need. Really surprising considering how many positive comments are on here about them.

Oh, very important, always run a ground from the main panel to the ground next to the input hot leads. Next, run a ground from the chassis to your output source. The chassis ground is on the far right corner looking at it from the bottom. You can see the ground at 8:15 on the video. Super important to do this.

would you use the ground next to the input leads for the grounding rod buried outside or the chassis ground ? or both?(i wouldnt have shore power or a generator connected to the input on the inverter in my case)

The system would perform even better a set of at least 1000 farad, graphene capacitors on the DC supply side, paralleled with the battery input into the inverter. The capacitors would take up the slack to keep the batteries from being hit full force with the surge current from inductive load start-ups from the house air conditioning units, saws, etc.

Thanks for making videos on this inverter I've been thinking about getting one. I have a MPP solar LV 5048 off grid set up with the Nissan Leaf Gen 2 batteries I didn't really know what I was doing but I copied the settings from a KZbinr and got it working learning as I go. I saw something about the recommended minimum battery capacity being 24 kwh I only have about 8 kwh and the Nissan Leaf G2 batteries are hard to come by right now so I don't know if it's a good idea to get rid of my system and start over or wait till batteries become available and just change the inverter. Either way I look forward to your next video on this inverter.

[@AveRage_Joe]

You are welcome! I almost went with a LV 5048 but seen they couldnt start a saw unless you had 2 units. The manual for this 12kw inverter recommends a 400ah battery but its just a suggestion. My current system is only a little over 200ah and everything is just fine. Like I mentioned in video my draw back was the wires I used during the build. You can use whatever size battery you want but it would be best to make sure its capable of delivering over 250amps if you want to use the full 12kw from the inverter. I can supply my entire house off my battery EXCEPT my dryer, stove and AC at this current time and thats only because of my poor planning in the 2 10awg wires on the battery packs. Next battery pack will be a huge upgrade. So for you, Id either wait or add similar chemistry batteries to raise the AH so you dont need to redo system. I however am pretty much redoing my system lol

A work horse for sure. But has it limits on programming. One issues for me I had to change my battery setting from 56v to 48v due to not able to set the battery low cut off point. Parallel Nissian Leaf batteries stack of 8 & series each stack for 48 volts work perfect now. 56v worked fine too just wasn't able to set that safety cut off. Yes, I do have it switching back to utility on low battery source prior to low cutoff safety.

My max utilization according to the power company has been around 13KwH/day, so a 12Kw unit is certainly enough to work for me in UPS mode. It looks like it's worked well enough for you in a couple of videos, so I'm going to see if Will also give it a thumbs up, and probably buy this model. The long pole in the tent is my desire for 3-4 days autonomy, and that's in the battery packs and solar panels.

Great video. I'm considering a similar hybrid inverter, but one thing worries me. If the power company turns off the main power (or an accident occurs and the power goes out), is there a chance that the inverter will return voltage to the mains and someone get an electric shock. I tried to find circuit diagrams of this type of hybrid inverters to find out exactly how the energy is converted, but I'm still not 100% sure.

[@AveRage_Joe]

Thanks Mate! They way this is actually connected in real use case there is no way to send power back through the grid. Ive had it connected for a few weeks now and I am supplying the inverter with AC from a sub panel, the AC output is connected to the panel showed in this video and I have installed an interlock kit so only the inverter or grid can power the panel, not both.

So here is my question. if I connect 5kw of solar and grid input and I am drawing 10kw will it use 5kw solar and only 5kw of grid power? is that even possible? ie will it use the solar and less from the grid if the solar is available? can it use power dynamically like that? Can I use 2 of these? I have 100amp service so I need 20kw for "full capacity" can 2 interact like that? (I know syncing phases is tricky and hard to do) ALSO can I put it on a timer plan programming kind of thing? for example I want it to switch to solar battery only at 1630 and then back to grid when battery runs down or it gets to 2200 (time of use power power is twice as expensive in those hours)

[@chrisbullen4317]

Great video and lots of comments in reply. Is the 160 watt standby power a good thing for these low frequency inverters? Is there some way around that? If I dont want to be burning thu 160 watts every hour on my batteries and want to have 120 volts at my house outlets what can I do ? I suppose in the day time the solar panels should cover this loss but after dark Im losing 1.6 kwh per night.

[@AveRage_Joe]

Thanks Man! Yeah the 160w is high but pretty standard for this size of inverter. Im not to worried about it at this current time but Ive been use to higher idle draw from the 2700w UPS I was using for an inverter. I know the high frequency inverters have a lower standby or idle draw but not many are split phase and cant start a regular saw or compressor.

Enjoyable video. Does the inverter have a mode that allows the inverter to use pv and battery and grid-utility power simultaneously? Allowing the grid to only supply the excess power needed for loads that is above the inverters max output?

[@AveRage_Joe]

Thanks Man! Technically the inverter will do all that! It will power from solar first, if not enough then also uses battery. If battery is dead or low it will use grid! Max load above the 12kw is 36kw but for short time. Hope I can test that here soon!!!

[@RJ-cc1fz]

@@AveRage_Joe so I guess there really wouldn’t be any time that you have more loads than the max capacity of the inverter with such a high capacity. I was wondering if it would shut the inverter off like a standard offgrid inverter, or if it would continue to put out its max but still allow the grid to supply the remaining power needed to fully supply all the homes load

[@RJ-cc1fz]

If it could do this then a smaller inverter that covers the majority of continuous loads could be used. Then the system could be cheaper with a smaller battery that wouldn’t have to supply power for surges and occasional high loads. Easier on batteries etc. this would only be beneficial if there was a grid connection to the home

A multimeter check shows that there is voltage... I have to switch the inverter off, and then it will find the panels and start charging b) is there a way to charge the battery from the grid without activating passthrough ? My grid, which is actualy a gasoline generator, outputs 1kW only and it's quickly overwhelmed by the loads Thanks !

[@AveRage_Joe]

Nice! Ive been wanting to test one of those out! Only thing I could think of if it doesnt start charging from solar is I would do a firmware update! Its super easy. Look in signature solars youtube and they show how to do it and where to get the firmware. For the 2nd question to charge from both and not passthrough is have option 1 on SBU and option 14 on SNU.

There are 2 ways to do it. Off grid or grid tie. Grid tie is connecting panels to either grid tie inverter then to panel or micro inverters (batteryless). Off grid needs a puresine splitphase inverter with built in charge controller (like mine) so the solar panels can connect to it and inverter connects to your main panel (thats the easy way) or a puresine splitphase inverter and a seperate charge controller for the solar. Offgrid of course needs batteries.

Great video, very instructive.

[@AveRage_Joe]

I cant say 100% or not but honestly dont see why it couldnt. You would run the 12kw as your "normal" offgrid power and the gridtie would sync to it and lower the load. Only issue I could see is you would probly want to make sure you dont send to much back to the 12kw. Just a reminder tho this inverter is an off grid inverter and needs a battery to work and it cant send power back to the grid. Yeah you can find these inverters on alibaba!

[@DavidHalko]

Hi @@robertmariuszpozniak6482 - “Can you advice if this inverter can withstand returning power from my existing on grid tie inverter?” This is a good question. It is the same situation that I am running into. Genetry Solar makes a low frequency inverter that will do EXACTLY this! This is very tricky, because the inverter must measure the input and output power, take the excess output power (from the grid tie) and sink it to the batteries. (If it can not sink the current to the batteries, it will blow the MOSFET’s.) The low frequency Genetry Solar inverters will also try to frequency shift the grid tie inverters, to shut them off, if the power is still to high. Finally, the Genetry Solar inverter will just shut down, if it can not charge the batteries with the extra Grid Tie power or throttle the grid tie inverter, to keep from blowing the MOSFETs. If this is a problem, you just buy more batteries, to sink the power from your grid tie inverters to, on the Genetry Solar Inverters! I would be VERY cautious about buying any inverter, where you have grid ties on the output, unless YOU KNOW the inverter manufacturer will support this configuration. I just received my Grid Tie inverter and screwed it to the wall… doing the rest, now! Have a great day!
