Upgrading Our Solar All-In-One Inverter by PowMR

[@hwoodist]

Unlike most YT videos, the end was worth it. In the process of putting together a system for my home and thankful to learn about the importance of the max open voltage.

[@TonysTractorAdventure]

Thank you. Check out my other channel. Southern Solar Academy. I am moving all of my solar stuff to that channel. Many tractor people don't care about solar.

Great video, specially the end display explanation. Thanks. I just purchased the same unit and will be insalling it next week.

[@Hfoutdoorsyt]

Good video

[@UnkyjoesPlayhouse]

A good choice, get the unit that has the largest PV voltage and you will thank yourself in the long run. No combiner boxes or multiple cables needed.

[@rollingmancave4547]

I have been running a 5KW PowMr all in one in a 48v system with 2,000 watts of solar panels and 800Ah of LiFePO4 batteries. The system has worked great for 3 years, and I live on the road full time in my Enclosed Snowmobile Trailer to Tiny-Home/RV. I am 100% off grid all the time. I have a tri-fuel generator but never use it. I have a split AC/Heat Pump and full accoutrement of 110v home appliances including computers, big screen TVs, full size refrigerator, incinerator toilet, washer & dryer, and more.

[@pstoneking3418]

​@@rollingmancave4547Series connecting batteries increase the voltage but the current remains the same. With 4 12 volt 200 AH batteries in series you have a 48 volt 200 AH battery bank. To increase your system to an 800 AH bank you will need to repeat your battery series connections 3 more times then parallel all 4 strings. For a 48 volt 800 AH battery bank you will need 16 - 12 volt 200 AH batteries. That will be a very nice battery bank.

awesome informative video!

Thank you

[@Tapthatsugershack]

Awesome stuff as always and looks like a really good product and can handle more panels for u at a later date

[@TonysTractorAdventure]

I am planning on upgrading next year to a really big system. This has been a learning experience. POWMR was kind enough to let us test this upgraded inverter. They seem to make good stuff at a fair price.

[@cutweldngrind]

I dont have money right now but will buy one of these inverters soon. I have a 2500w array and only using 3 250W panels on a waterwell pump. These inverters were about double the price when I added one to my cart years ago. Cool shed...

[@skipbasil2937]

Nice explanation Tony

[@TonysTractorAdventure]

Glad you liked it

[@BobbyElliottav]

The Sungold 3000w unit I bought has been up graded!! It can handle 4000 w. Like you said, tech changes daily!

[@TonysTractorAdventure]

Yes sir. It changed right after I made this video.

[@psikogeek]

I too bought a Sungoldpower unit 2 weeks after you. It does claim 4000 Watts although I don't need more than 1200. Guess I shoulda offered to buy the used one. : )

[@Bodhranarama]

Good looking product Tony. I know you metered those tails out before you messed with them.

[@TonysTractorAdventure]

I licked each one! LOL! It was a shocking experience. :)

[@rollinronin8125]

One thing I noticed about the sungold over the Powermr is the sungold has 120vac input and output voltage whereof the powermr only has 110vac. Grid is typically 120vac. Appliances have a range of 106-125vac. Having the higher vac capacity of the sungold will keep your appliances hapoier and less likely to brown out and fail. I think I would have added an additional charge controller and panel up. By the way the first video I 've watched from the channel is about the solar tracking array. Very impressive. Keep rollin. Great content.

[@jerrytalley802]

Tony, I just recently watched the install of the Sungold power, now I need to see why you switched, and may go right to the PowMr, lol. I’m thinking it is something to do with how much solar input it can take. I’m thankful to see your videos. You are the first person I have seen install circuit breakers on the solar input and the battery input. 99% show a metal fuse, so much easier and cleaner your way, and easy to service with the flip of a switch

[@danielcraig9349]

Yes, can you tell us the idle consumption? Is that a high or low frequency inverter? I might have missed it in the video. Love how you went thru the various pages of the inverter setup at the end.

[@brianstarkey1824]

Great video thanks so much 😊

[@TonysTractorAdventure]

You are so welcome!

[@brucefrazier9051]

Enjoyed watching, I'm running a 24/70 victron with 18/320 walt panels. I'd like to see more 24V installations in utube land

[@RigidPanman]

Thanks for posting this video, I have the exact same unit.

[@ewitte12]

Ordered one of the smaller ones that only needs 30v to work. This is an emergency setup it will have a maximum of 440W (currently) in panels on it. I'll have to throw these in series just to get to 42v. It has a 100w load but I may use it to charge the ECOFLOW fast since it can handle the full 1800w load.

[@Markslife101]

Please do show the video of how your system is set up, it would help me greatly!, thanks for this video, I bought this same setup

[@SuperSushidog]

Good video. I will be ordering a 5,000w SunGold Power All-in one 48v inverter charger before the end of the month as they are on sale till Nov. 30th. I purchased 8, 550w SunGold Power solar panels that I will be racking on the roof of my motorhome and wiring in series. They just arrived a few days ago. This is the maximum number of panels I can fit up there, covering my entire roof. Though I have another 620w array on the side of my motorhome on a separate 50a 12v controller to charge my 7.1Kwh 12v battery bank. The 550w panels have a Vmp of 41.96v and a Voc of 49.9v, so the 8-panel string will have a Vmp of 336v and a Voc of 399 volts. This works out perfectly for this 5,000w all-in one system, which will handle a Voc of 500v. The MPPT voltage rating goes up to 450v, well under the 336 Vmp of the solar array. This keeps the amperage from the solar array down to an IMP of only 13.11, perfect for the controller's maximum of 16A. The total rating of the array will be 4,400watts which matches well with the controller's 5,000 w maximum power output and 5,500w maximum input capacity. This high voltage system will help keep my wiring size and complexity, thus the weight, to a minimum. I just need to be very careful and deliberate when wiring everything up, as DC voltage in this range can be instantly lethal if a mistake is made.

[@imdadali3069]

How is your system operating after installing?

[@rollinronin8125]

In alot of cases charge controllers/Solar panels and 12v batteries will work in a 12v or 24v capacity. So an upgrade from 12v to 24v is a easy and cost effective transition. Note: when inverting from 12vdc to 120ac you are making a 10:1 ratio conversion with a scaled losss of efficiency whereof a 24v system you are suffering half of that 5:1 loss of efficiency. When you scale up to 48v system than you are cutting that in half again. + or -.

[@stoneoriole]

Something that is important is to torque every wire to spec. Loose wires cause shorts sparks and fires, not just for solar but for electricity in general

[@echo2papa2]

I am considering getting a 5000 watt PowMR. Do you know if this system generates any RF Noise that might interfere with a Ham Radio system? Would you be willing to show the interior of the PowMR in a follow up video so we could see how well it is built and what level of noise suppression they used, specifically the number of big toroid cores used.

[@samhalburian4712]

I don't recommend putting your panels in the shade. LOL! I am sorry, that was too easy. My panels get sun from mid morning until late evening. I set it up optimally for my situation. I am looking at micro inverters at our cabin.

[@ultrahighgain412]

Does the PowMr have an internally bonded neutral?

[@TonysTractorAdventure]

The PowMr 3000W inverter does not have an internally bonded neutral. This means that if you're using it in a system where a neutral-ground bond is required, you'll need to handle that bonding externally, typically in your main distribution panel. If you have AC input connected to the grid, the neutral-ground bond is usually already present in the grid connection, and you should not add another bond within the inverter. If the system is entirely off-grid, you might need to create a neutral-ground bond at a different point in the system, such as in a load center or distribution panel

[@ultrahighgain412]

@TonysTractorAdventure The POW-LVM5K-48V-N shall be used to power a residential electrical panel in a 100% off grid camp. Just wanted to know if I should bond the neutral to the ground in the residential panel as one would in a typical utility serviced primary panel. Sounds like the answer is yes. Thanks for your response.

[@fpmd99]

Great video. How do you ground your AC output? I have seen some connect the ground wire from AC output to the ground from AC input. Also, how do you ground chassis? Thanks.

I have been thinking of trying out the PowMR unit. I have worried about the support they have, I heard that SunGold is far better for tech support, but who knows.

[@JoeCarlinCA]

I was wondering that, less about tech support and more about reliability. I've heard of some SunGold units going out after 5-6 months and then taking 8+ months to get a replacement.

[@donb6474]

If needed you can always get a seperate controller to help charge your batteries. Your VOC is the voltage you add up and don't go over their requirement. If you lay your panel down at noon and get a multimeter that is the voltage you should see. Same with AMPS. I have been wrong in the pass so don't take anything as gospel. Good Luck..

Guess I need to hire a pro.. glad your is working..

Not sure where you got your info but the latest Sungoldpower 3kw has the same specs as the one your installing.

[@matthewknight5641]

I have the all in one powmr also. The problem i found with it is that it often locks in on a low voltage pv input and doesn't reset itself to a higher voltage when its getting better light. I ended up buying a 150-70 victron charge controller and my power input has more than doubled with the same exact panels. The victron was kinda expensive but definitely a game changer as to how my system performs. I have a fairly large battery bank and now use a low frequency sungold power inverter which was also another great investment. Good luck with the all in one inverters i still have mine but do t use it nearly as much. My all in one is kinda a backup unit now and our home runs from the seperate components

[@TonysTractorAdventure]

To this point, mine has worked flawlessly. There are so many variations on how to set it up.

[@matthewknight5641]

@@TonysTractorAdventure the biggest thing I figured out with my all in one unit was the grounding situation. It would trip a GFCI on my house 120 volt that was going to the AC input on the inverter if I had the inverter AC out put grounded to the neutral. After a ton of videos I found a guy that clarified a lot for me and ended up talking to him about and he walked me thru how I need to wire things so that it was still safe and I was able to use the AC input to make the 40 amp charger still work and the AC bypass to still work. Seemed it was all good in until id turn on power to the AC input side for the AC charger but then problems and by using a relay it was an easy fix but not something I'd have known to do without some help. Anyways now the only time I turn on the all in one unit is if I'm needing an extra 40 ps of charge or if I want to use my leaf batteries to put some power back into my other system. When I get home off the road I'm thinking of hooking up the all in one unit and my leaf batteries to the water heater and that kinda being its own system and taking the water heater off my regular panel. I figured it will help my lifepo4 batteries not work as hard and give that load to the unused components that's just basically sitting there not doing much. I'm almost always on the road in this truck it seems but when I do get the chance to get home I spend all my time messing withy solar stuff. Glad you make the videos wish I didn't have stage fright id like to do the same

[@jimslickster6621]

Nice video, just a little confused about your 4000W solar input statement. If the charge controller is only 80 amps, that is about 2000w (24v system) to the battery. How would the other 2000w of solar be utilized?

[@TonysTractorAdventure]

Don't over math it. 4000 watt input PV doesn't translate to exactly the same output wattage in another voltage. There is loss during the process. Just because the panels have the potential output, doesn't mean they will always do it. If you have more potential, it will met your needs on the less than perfect weather days.

[@pstoneking3418]

That's an 80 amp AC charger, not related to the mppt charge controller which will accept up to 4000 watts of solar at 120 to 400 volts. You do need to be sure to limit the input wattage else you can damage the solar controller, especially in the winter when the panel are cold when they produce more power.

Hey tony, Sam here, my question is how large is your battery bank, I have the same system as you but my batteries drain very quick, I have 2 100 ah lithium batteries, hey any help would be helpful, thanks for your time

[@TonysTractorAdventure]

To size lithium batteries for a solar system, you'll need to consider several factors: Energy Usage: Calculate your daily energy consumption in kilowatt-hours (kWh). This involves assessing the power requirements of all the devices you plan to run on solar power. Days of Autonomy: Determine how many days of autonomy you want your system to have. This is the number of days the system can operate without solar input, typically during cloudy or rainy periods. Common values are 1-3 days. Solar Panel Capacity: Calculate the daily solar energy production of your panels. This depends on your location and the efficiency of your solar panels. Ensure it's enough to meet your daily energy needs and recharge the batteries. Battery Capacity Calculation: To calculate the required battery capacity (in kWh), use this formula: Battery Capacity (kWh) = Daily Energy Consumption (kWh) x Days of Autonomy Depth of Discharge (DoD): Determine the depth to which you plan to discharge your lithium batteries. Lithium batteries can typically handle deeper discharges (e.g., 80% DoD) compared to lead-acid batteries. Voltage and Configuration: Choose an appropriate battery voltage and configuration (e.g., 12V, 24V, 48V) based on your system's requirements and the compatibility with your solar charge controller and inverter. Battery Type: Select lithium batteries suitable for solar applications. Lithium iron phosphate (LiFePO4) batteries are often preferred for their safety and longevity. Efficiency and Temperature: Consider the efficiency of your battery system and how temperature affects its performance. Some batteries may require additional cooling or heating mechanisms.

Can it work with just solar without batteries?

Not reliably. Every time a cloud comes by, it would shut off power. It is not meant to be tied to the active grid.

I see the MPPT voltage range starts at 120 volts, so I assume you must have at least that amount of voltage comming from the solar array, is that correct?

I have a video coming out soon that will explain. MPPT.

I have 2 Growatt 5000 us version. if you are gonna do 240 volt or 2 120v lines you will need an auto transformer to balance the lines. I can bring in 6000 watts solar in each unit( 450V open circuit and 22A) 440 max from solar and 22 amps max. These just work and are so affordable. These are for 48 volt systems.

Thank you for your comment

One thing that needs more explanation is when you are doing a shop situation. My shop gets power from the grid that comes from a heavy line from the house underground. That's pretty normal. So most guys will want to use a hybid system, with 240 and somehow have the option of sending power back to the house through the existing underground line. Obviously you can't have power from the grid that doesn't first go to the hybrid inverter. So the inverter power output has to go to a separate sub panel. Which means you can't use the existing plugs and lights wired to the existing shop and house wiring. That's nuts. To use your existing wiring you'd have to have a dual power automatic transfer switch that your grid and Inverter go to. Comments?

What gauge did you use for the battery goint to the inverter?

2AWG. All the requirements are in the owner's manual. It can be downloaded from the manufacture for full requirements.
