I have this same unit. You can note that if you are off grid like me, you can connect your generator as your AC in. So on a cloudy day you can just turn your generator on and get the same charge/use benefit.
Thanks for sharing!
Does it has an ats for generators?
I enjoy your reviews, I hope your channel takes off.

Excellent video thanks!
Glad you enjoyed it! Thx
Great video! You touched on something I could use a little help with. Bonding. I am in an RV. I have a 3000W unit like this. When I connect me unit to the RV I'm using a 50 Amp (NEMA 14-50) on the RV and the same on my solar shed. I wired the connections with a jumper for the 2 live legs. I have an 8 foot grounding rod. Should I be providing a ground to the unit to the grounding rod? Or to the distribution box? And should I leave the green screw in to bond the ground and the neutral? I would really appreciate the help. Greg
Hi Greg, I would definitely run that by an electrician. There should only be one ground neutral bond and that would be at the first point of service. If it's a subpanel, you should remove the green screw. You would not want another bond after the main service panel. Hope that was helpful.
What is the rs 232 port, on the left hand side, for?
Thanks for sharing - great info! What is the minimal PV-input voltage the MPPT-charger can work at? And what is the MPPT-range for input from PV? Did you measure the stand-by consumption with inverter on/off? From the batt. it is probably about 20...40W but from mains input it often takes much more - don't know why? With inverter off it should be less.
I would refer to the product manual of the inverter on PowMR's website to insure you have all the information you are looking for. Thanks for watching and commenting
Good job 👏
Thank you! Cheers!
Nice watching. Regards
Many thanks
I have 2 of the same units I just finished installing with 3000w of solar for each unit I installed a separate panel next to my main panel I removed all the circuit's out my main panel except the double pole breakers and put them in the new panel total of 24 breakers 12 breakers on each leg 12 on inverter 1and 12 on inverter 2 total of 24 breakers 15 and 20 amp breakers running 8# wire from inverter to second panel and same for utility input been running now for 3 weeks no problems at all I'm using 24v 600ah lifepo batteries on each inverter each inverter has it's own set of batteries of 24v 600ah each inverter in the panel the inverter is hooked up to a double pole 40 amp breaker as a main breaker disconnect I'm going to post video in the next few days so right now I'm 80% off grid only thing hooked up still to grid is my a.c. unit and heat unit everything else is off grid from 11am to 6pm running off solar only after 6pm when sun goes down batteries kick on running off batteries at night and only use about 20% of batteries at night till the morning then solar charge back to full then once full then house runs off solar
Awesome! Love hearing things like that. Thanks for watching and sharing your experience 👍🏻
Sounds like a nice system.
Post that video soon please.
Thanks
Thank you for watching and commenting 👍🏻
you can control at what voltage it should switch from the battery to the power grid and at what voltage it should switch back to the batteries
Thanks for watching and commenting 👍🏻
got this system put together .. now taking it down to the RV.. do i need to worry about backfeeding the grid? i assumed the AC input was to charge batteries and / or bypass to run the load.
It is not a grid feeding system. You assume correctly. Thanks for watching and commenting 👍🏻
@@JustinsProject question on the ground.. i am not using a distro panel.. literally just pushing the AC - OUT to a dual 110v outlet.. so the ground and neutral can connect to the same AC OUT neutral?
Can the input and the output 240v be paralleled if you intend to feed the power from thr inverter back into thr main distribution panel?
This model is designed for Off-Grid use.
Thank you! The information you provided was beneficial and insightful.
Glad it was helpful! Thanks for watching and commenting 👍🏻
Hey Justin do you have a link or model number for the load center I can't seam to find it on the internet. Thanks
It's an Eaton load center. I picked it up at Menards.
About three years ago, I purchased six 24V 200W solar panels (before I knew what I was doing...thinking bigger was better). I have several other 12V 200W which are perfect for my 150VOC charge congrollers. But I still have those six pigeons...24V, each with 45.4 VOC. My battery banks are 24V. All of the panels are ground deployed/moveable...so with those six panels I'm stuck with a 2S3P setup (sucks). I've been looking for a 450VOC charge controller but they are pretty much geared for 48V battery banks. Then I found this unit online. I'm really interested to know about your real life experience with this unit...reliability, etc. It's really inexpensive (IMO) so I'm wondering about quality. What do you think about using it as a solar charger only? (backup inverter) Thanks for your video!
I think it would be great as a solar charger only! That is what I will do with it once I get my mini splits in. Thanks for watching and commenting 👍🏻
i have been running a 24v 3kw unit for almost a year now , i have 5 505w panels in series connected to it ,,spring summer fall its a powerhouse , altough a bit noisey. in the winter here in skandinavia i find that its hunting a bit to much for the powerpoint charging stopping charging stopping (it could be that i just have to few panels in series 250v )and they like to stabilize around 220-190v under load and it dip under that when it start charging ,,all in all i am very impressed with this unit and the funtions it have for the very low prize gen or grid input bypass powering e,c,t as it cont the same as a decent inverter alone ,,i can recommend..
Do you know anything about the PowMr 12v 1600watt AIO? as far as i can tell it only puts out 220v @ 50hz. It would be perfect for my use if it were 120v @ 60hz.
Im curious if there is a setting that changes the hz from 50 to 60 on your model.
I don't. It might be on their website though. If you find it, let us know.
Does this all-in-one have the generator hook up to run a generator say for an ac window unit on a small off grid solar system setup?
Thanks for watching and commenting 👍🏻
Yes it does
Idle Power consumption from the batteries would be very useful. Many of these units eat 50Watt when sitting around during night time, draining the battery. Espacially during winter they eat more than PV produces. Victron Multiplus 2 only needs 8 Watts during idle, they are much more expensive though
You are right, I should have provided that. Next time, I have it wired up I will add that info to the comments. Thanks for watching and commenting 👍🏻
Johguide5045. Oh yes, yes, yes i read that. Alot of powmr inverters are power zombies to extreme. They drain anywhere between 35 watts and 50 watts from battery bank, just sitting, with no load. Thats alot, people. Customers need to know that. That alone made me want to shop around and keep looking.
@@jab376 you get a multiplus 2 3000 for 500 bucks nowadays. 2 years ago it was over 1000
@@johgude5045where? I’m seeing $1350’ish for Victron
@@2hotscottpro here in Germany it is 530€ ATM. I would recommend Panda Solar even if it is a bit more expensive there
Hi mate. I have powmr 3.2 24v hybrid inverter and my question is in the Philippines we have 220v on our socket via grid. and Do I need a 12v converter if I will use gadgets with only 12v and below? or It is safe to use the 24v powmr system to 12v gadgets without 12v converters?
Do not try to power 12v appliances with 24v outputs. It will cause damage to the appliances.
I have PowMr3000 connected through a connecticut electric transfer switch, I am unsure how to earth this unit. your instructions appear to be a separate earth, the Pow Mr video says ground as close as possible to the unit.Can you advise please
Thanks for watching and commenting 👍🏻
There are many versions of this inverter on the market.
What I couldn't find out is if it could bypass straight from the grid to the appliance. Dose this mean you don't actually need a battery?
I want to set this up for my 2kwh hottie heater and make it as cheap as possible.
My hot tub cost £1k a year to run and adding a 3kwh solar array will definitely take that price down.
In the uk I can build this for £700 including the pannals.
But if I can save money by not buying battery it would save me £1.3k.
Please advise me.
Thanks for watching and commenting 👍🏻
What would happen if you plugged a micro inverter into a power station 120ac output to power it?
I haven't tried it, but it might be something I will experiment with in the future. 😉 Thanks for watching and commenting!
Thanks for this explanation. I need to know the quality and durability of this powmr before buying this. Can you help me with this?
From the test I conducted, it functions as it should.
I had the 2.4 kW version it didn't last long and had no built-in fuse
@@lucienrobinson685 For just a test they all function as they should. but if a test means having it for your personal use, then how long they last is a real question. thanks a lot for your review.
@@lucienrobinson685 thank you so much for sharing your experience.
So the ground to the sub box comes from the ac in right? If thats so am i ok just grounding the solar panels to earth ground? 8ft rod
As I hit send you answered it in vid lol but would solar panel cases be ok on own ground
It really depends on the design, whether you need an earth ground rod or not. For example, my 10kw system only needed an equipment ground ran from the racking to the combiner box. Then, I ran directly to the main service panel. In some cases, if you ground to the earth, you could create a ground loop. You don't want that. In other designs, you would be required to earth ground the racking system. I know that doesn't help much, but without physically reviewing the electrical system, I don't know. Maybe post your question over on the diysolarbuilds.com forum. As we grow, maybe an electrical engineer will see it and answer.
@DIYSolarBuilds the solar panels should be fine on ground that's for static and electric strikes. I suppose if I plugged the ac in it would cause ground loop if I kept it off then no. It's just the issue is there's no sub box near by and main botlx is in seperate house
@DIYSolarBuilds ok did more research I'm going to ground the panels to combiner for electrical and staic. On the inverter would I be fine with ground from an outlet. But do you know if the ground on ac out is combined internally with ac in or should I bus bar those 2 ? I'm trying to do the same thing you did but that model doesn't have the ac out ground so ig that ones internal
hello, the inverter 10.2kw pow mr stil work without battery and without ac in? (only pv powered)?
Thanks for watching and commenting 👍🏻
No
Hola una cónsulta en la etiqueta dice que la entrada de voltaje mppt es de 120 a 400v. Eso quiere decir que si solo tengo 2 paneles solares de 24voltios que en serie entregan 62 voltios el cargador solar no me funcionara por el poco voltaje?
You will need enough voltage to wake up the MPPT.
Can I connect 2 inverters? I need more power than 3000W. Thank you
Just to confirm your setup, check out PowMR website and locate the product manual to insure it will do everything you need. Thanks for watching and commenting
so is the powmr still going? Im thinking of purchasing one
Yes. Thanks for watching and commenting 👍🏻
what type of battery did you used sir
This is the exact battery I was using: amzn.to/3NR3eot - I also have a review on that battery that can be found here: ua-cam.com/video/3rVQQvVdfD8/v-deo.html - Hope that helps. Thanks for watching and commenting! 👍
I install this inverter but when i connect the pv don't charge the battery
It should. I would contact support and have them walk you through the setup for your configuration. Thanks for watching and commenting 👍🏻
i just sent back my chin's 3000w as the AC did NOT charge the battery.. remained 0a .. so will probably be buying powMR after i return the chins.
Hopefully, you get that all worked out. Good luck. Thanks for watching and commenting 👍🏻
I'm going through that now it's doing the same thing I luckily bought insurance on it .
@@tracydjenkins I just got the powmr yesterday and set it up in a test bench.. works GREAT.. i run 2x 200ah lifep04 in series with a 60amp breaker to it.. AC power in with a 20amp 3 prong cord, put the 20amp outlets on it.. my only concern is its charging the batteries at 40amps.. and the grid power cable is getting slightly warm, wonder if there is a way to lower the amp charge to 20?
Can anybody tell me of an electronics shop that can fix hybrid inverters like the PowMr 10.2?
Depending on how old your unit is, you might check the manufactures warranty. Might be covered.
It is new and they refuse to help get it worked on. PowMr tech is no good. They will never recognize a claim. They deny all responsibility and even claim there is no problem and told me they were done with it.@@JustinsProject
A step drill bit will fix that knockout not fitting
Good tip. I have one and didn't even think about trying that. Thanks for watching and commenting 👍🏻
so I don't understand.........why is there ac from the house coming into the solar inverter? wouldn't you want SOLAR coming into the solar inverter? im very confused and new so trying to understand LOl
The AC coming in can help charge the batteries if that is needed. Typically, you would let the PV array charge the batteries. However, it is useful to have an alternative charging option. Thanks for watching and commenting 👍🏻
hey thanks for the clarification. OK so it's just a backup charging setup while you have power and when you don't it switches back to solar. Makes sense now. Thank you for your video and quick response.@@JustinsProject
whats the standby draw tho?
I will need to test again to confirm. Thanks for watching and commenting
how is your PowMr working today?
I use it from time to time. It is still working fine. Thanks for watching and commenting 👍🏻
?Ok so it's an all in one inverter, but what about 12 volt power? What if it's a 48 volt system and you need to power your air conditioner? How about power for USB ports? I'm new to this but I don't understand how you can say it's all in one system when you need the other power sources?
All in one, meaning you don't need to purchase multiple components. Like a solar charge controller and inverter. It is a combo unit. Depending on your system, 12v, 24v, 36v, or 48v, you need to purchase the right one. Thanks for watching and commenting 👍🏻
To get 240 V doesn’t the phases have to be separate 180°
120V on each phase. Thanks for watching and commenting 👍🏻
Be sure your battery can handle 80 amps of charging, it's adjustable in the settings.
True. Thanks for watching and commenting 👍🏻
How do you work out if your battery can handle 80amps of charging? I am off grid (PV run only) and have 2 x 12V/250 amp gel batteries (set up in series)
@@sandrapetretich7045 There should be a recommended charge current in your battery specifications / owners manual or search for AGM charge current.
Can two solar panal start the system??
Hola yo tengo la misma duda si solo tengo 2 paneles que en total entregan 62 voltios esto iniciará la carga porque la etiqueta dice de 120 a 400v ???
Thanks for watching and commenting 👍🏻
Also wouldnt you put 200a fuse to batteries?
If this was a permanent setup then, yes I would have. Thanks for pointing that out, though. I should have mentioned that. Thanks for watching and commenting 👍🏻
40amp charging the batteries but the amp wiring and ac receptacle is 20amps. Hmm sounds like going to pop that breaker. Don’t you need to lower the ac charge input to under 20amps?
That's charging at 40amps DC. That's only taking about 8 amps of the ac input. I have the same unit
Thanks for watching and commenting 👍🏻
Not sure the bonding setup is correct. Unlike a true sub-panel the source is the inverter, not your main AC panel. Electricity wants to get back to the source. If a hot wire suppled by the inverter touched the metal box it could not get back to the source through the breaker the way you have it. The AC IN is grounded to the inverter so if the black wire touched the inverter case it would trip the breaker that supplies the input. But then again I could be wrong. I think the load center supplied by the inverter should be bonded.,
Something I will research a further. Thanks for watching and commenting 👍🏻
Did you ever get to determine if the neutral bond from your main grid panel is sufficient, or do you need to bond the panel connected to the inverter?
@@user-os4dd1xf3k From what I can tell, you do NOT bond the load center. When connected to grid power the inverter is bypassed and the main panel ground is primary as in any other sub panel. You do connect the green grounding wire to the inverter ground/green terminal providing the ground when the inverter is in use. Still not entirely clear to me how bonding is achieved if “grid power” is coming from a generator rather than the main power utility.
@@user-os4dd1xf3k Also, when I say ground I really mean “alternate return path” since it really has nothing to do with the ground we walk on. The green wires are an alternate return path to trip the breaker if the hot wire touches something metal that doesn’t have a white wire. Whatever.
Ebay has these for 300 bucks.
Awesome! Thanks for sharing!
This may be a wrong ground wiring. Why don’t you use your multimeter to check the voltage between neutral and ground. Let’s see what voltage is there? If it’s correct then Neutral and ground should be 0-5 volts. The reason it’s wrong is where did you get your ground that is going to the ac outlet. This maybe dangerous please test with your multimeter
I'll check it the next time I have this configuration installed. Thanks for watching and commenting 👍🏻
You are correct. When measuring between the ground and L, and Ground and N at the controller, it is 60 VAC from Ground to L and to N. Both the L and N are floating from ground. They are taking the 24 VDC from the batteries and creating 2 out of phase 60 volt waveforms.
