- PowMr All in One and OFF GRID Solar Power Array
Quick video of a solar array setup, 2000 watts of solar, 50 amp hours of 48 volt battery and 3000 watts of inverted AC
i am setting the powmr3000w with 2x 12v 200ah lifep04 in series for 24v .. with 1kw of solar.. and 20amp grid power for my RV ... tried chins and originally had a 2k straight inverter .. so settled on powmr. but the whole system is 24v (2x (2x)100w thunderbolt panels in series and then got a couple 330w 24v panels running to an mc4 combiner.. really really like it for a first solar setup. with lifep04 prices dropping like a rock.. each 200ah lifep04 was 460.00 shipped.. 2.5kw ea .. may go up with another pair.
In the manual they show a battery image with white bars coming down from the top. With no white bars the image is all dark and the status is listed as 75-100%. This may seems obvious to some people but it doesn't say if the status is charged or discharged. I think it would have been more intuitive for me if the charge indicator bars came up from the bottom. My system shut off with red alarm flashing and the battery logo was all black. So now I know for certain that all black means discharged.
for ur pump u could look into a "softstart" . on a rv a/c with a softstart it can be run on a 120v wall circuit where with out u have to be plugged into 30 amp plug.
Thank you for video and time. Its good investor from cheapest on the market bacause its made be SRNE factory. Not all models PowMr made by this factory .
I have a 3kw EG4 unit now which seems to work better related to the MPPT controller and its voltage tracking.
I ordered a 6.2kw 48v powmr. My aim is to charge a battery at night on cheap electricity rate and discharge during the day at expensive rate. This system will work for this? Appreciate any advice thanks
yes absolutely it would. great idea!
How did you handle the ground/neutral connection in the panel connected to PowMr? Does the unit bond or is it an open ground on AC output? I have a Growatt 48V and it does not bond on AC output. My unit is off grid with no possibility of grid power coming in ever so I have decided to bond in the panel and run to a ground rod after reading so many different opinions. Even electricians seem to get stumped on this but Will Prowse seems to say no ground rod is necessary on a completely off grid system. Confusing.
You do need a earth rod with these systems if you go completely off-grid. I found out the hard way. Everything that was being charged gave me a tingle, because I did not earth the unit. Ended up earthing the unit to the houses AC and no more problems.
You definitely need to ground your off grid home
I got this hybrid inverter. When I plug in the solar panels, the box doesn't detect any PV. I can see on the screws of the terminal blocks that it has 22v from the panels, but nothing coming in. No green light to indicate charging. I have tried changing it to 'SOL' mode, not result. Can I fix that, or did my unit arrive with some kind of problem?
pretty sure you need minimum... probably 80 or 100 volts or something. 22v is low and probably not enough to wake it up basically. Try them in series, this unit takes up to 150 volts if its the same one. You should get it near max of the top voltage imput to maximize efficiency of the mppt controller
@@MicahGallant This proved to be correct. One panel was not enough to detect the pv input. I hooked up two 200w panels, and I now have a happy green blinky light. Thanks for your reply. Great channel.
@@MicahGallant So for the record at minimum around 40v to turn on the solar charging.
I have another question. At the end of the day when the unit stops receiving solar, it boots up and shuts down for about 20 minutes. It blinks all three lights, beeps, checks the voltage and shows it on screen. Then turns off. (I do not refer to how it sometimes has intermitted solar energy, Yes it beeps when it loses pv, but this is different). Does anyone know what setting might cause it to do that?
Hi there, what AWG battery wire fits into the system?
Good question. I don't know the max size. Any standard household wire fits in for the 120 volt output, and its meant to accept standard solar cables for the input, the size you'd buy off amazing for solar panel arrays. So it accepts all the standard stuff
Is this unit still working after two years?
I swapped this out with Signature Solar 3kw EG4 inverters (dual). the issue with this PowMr is that the mppt wasn't reseting correctly as voltage increased in the morning. so the wattage would not be high. you had to restart it to get the full input of solar. Not sure if they have fixed that but the MPPT resetting was a major issue. the eg4 units are near flawless, have been running the for over 2 years now straight.
Hi, nice setup. How have you solved that the power couldn't go back to the main system?
I just installed the 3000 watt 24v power mr and when I connect the ac in put to the grid and it kept popping my breakers
Are you trying to draw 3000 watts fro grid? It cant do that on a 15 amp breaker
@@MicahGallant I figure it out, the problem was when i connect the AC input the there is a ground to neutral from the wiring of the house, so when I trying connect my living room to inverter it kept popping the breaker. So what I end up do just run a hot to the living room cause, neutral there already. Cause I turn my main grid breaker off and supply current to the entire living from an outlet.
Mich erschließt nicht warum ich das noch mal absichern soll wo eine Sicherung im Kasten direkt verbaut ist ihr habt doch alle eine Macke
Is your inverter 120 or 230? I bought a powMr 6200w and it only puts out 230 single phase and I need to get 120 out of it and can't get any help from powMr.
this one was 120 volts
I like my powmr 3000 watt 24 volt model. I actually like it better than the others like it. It has a smaller solar input but its really not a bad unit. Im trying to use it in my camper. Im wondering what you know about the neutral ground bonding and if the input ac ground is broken when its switched off of ac input and running on battery? Any help with this is appreciated. Thanks for sharing
I don't know about the bonding there. Thats a tricky subject so I won't comment. I'll let an electrician say something there. I didn't bond anything myself though, just used it as is.
How have you gone with finding further info?
@@MicahGallant the neutral ground bonding is kinda difficult with thos unit. If its bonded at the ac input which it will be if you have a ac input then it will not be bonded at the ac out put. When you bond your neautral to ground as you are supposed to do on the ac output then it works right until you plug in the ac input and it trips the gfci. So the trick to make it work right and safely is to have a switch on your ac output ground. Have acoutput unbounded while using ac input and when you switch to solar or battery you need to flip a switch that bonds your neutral with ground
is your menu #1 setting in USB?
I am curious. Now a year later, is your PowMr still running like a champ? Or have you had problems with it?
had issues, MPPT wouldn't check voltage quick enough to take full advantage of the power output. Known issue with these units
Whats your long term ownership experience with this powmr unit?
I sold it after a year. the mppt doesn't reset based on incoming voltage properly with this unit. Went to 3kw signature solar inverter, eg4, it works great and has for multiple years now
great video. can you explain the parallel setup? Your unit have parallel port/card? I looked for same unit with 2 x parallel setup but wonder how to connect the 2 parallel units to grip the correct way.
You can technically run 2 of them because breaker panels have two 120 volt sides or rails. So one on each rail. BUT!! You cannot run 240 volt appliances across both rails because the AC is not synchronized. You need 2 units that communicate which each other to be able to do 240 like that. So i'm sure its very unsafe to run 2 that are not communicating but if all you need is 120, then its technically something you *could* do.
May i ask a question? The connection between Powmr and the grid must be to the box or can we use any sort of plug in the house?
Not the box. Its a separate wire into the bottom supplying 120volts. Input only
so you mean the AC IN of your inverter is connected to the wall outlet of your house by that black wire tapped with red wire? is the ground connected as well or just the live and neautral wires. tyia
cause I wanna know if I can do so. cut a power cable and get the live and neutral wires, then plug to wall outlet and then to inverter. would that work?
Does this inverter bypass battery when its fully thereby converting DC from solar panels to AC directly to supply load when sun is still shining? Your urgent reply will be greatly appreciated
I can't confirm that. I know many inverters out there do support that though
I don’t think it does. Unless there is a setting I have missed. But, from what I have observed, it shuts PV input off when the batteries are full. It actually seems to regulate the Watts down until full. I hate to miss out on the sunlight that I could still convert.
Interested in what you think of the Renogy 48v battery. Because i was shocked how quickly my lost capacity
I sold mine. It was lower voltage then the standard 48volt batteries. Never had it long enough to see longevity. I have raw lifepo4 cells now built into a 15 Kwh battery which is working great so far.
@@MicahGallant pretty awful battery to be honest. I'll be getting rid of mine as well
Would Renogy solar panels work with this system?
.most definitely
Can this operate with no grid attached at all???
Yes, need battery ideally. Will it work with no grid and no power? I don't recall, I think it does but might be wrong.
Can this unit bypass the battery and put the PV energy directly into a (dedicated) house circuit? I don't mean grid-tied, but similar to a grid-tie inverter, which puts all the energy from the PV into the house. I'm also curious if it could be AC coupled with a grid-tie inverter to provide power to it instead of feeding the panels into the PowMr. Thanks for the review.
Great question, i think you at least need a tiny 48 volt batter, could be 2Ah battery, just something to connect it to.
There would be a bypass control available. Mechanical or auto but talk to a electrician
Is the inverter still working
I sold this and moved to a 3kw EG4 inverter. At the time it was still working. Problem with these is the MPPT doesn't reset enough or quickly enough to adapt to changing solar array voltages so you don't make as much power as you should. So thats a bug or something there.
Is this still working?
I've upgraded to a 3kw EG4 unit as the mppt was not resetting based on higher voltage through the day. Otherwise it gave me no troubles.
Thanks. Looking for 5000 watt unit. Sungold 5000 watt unit doesn't look like it has a problem.
Thanks for sharing. What is AC out for this PowMr? All growatts have 220 v out put and needs transformer to 110 v output. Thank you and keep posting more videos.
Is your inverter 120 or 230? I bought a powMr 6200w and it only puts out 230 single phase and I need to get 120 out of it and can't get any help from powMr.
That no posible. You choise the wrong , you need to get split fase or 110V inverter
