EASUNpower?

Not holding my breath, but I hope that this extends to the current the PIP-2424LV.

I emailed Peggy at MPP, it would be a different inverter.  It sounds like it's the same one as EASUN, a hybrid style with the green case.  So probably just confirms it's made by voltronic, they just don't have it on their site yet.

Dumb question inbound! Could 2 of those EaSun 24v inverters "share" a 48v battery bank?

Say you had 4 12v batteries in series for 48v total but connect inverter #1 to only 2 batteries in series, then connect inverter #2 to the other 2 batteries in series. Then you could still charge with solar at 48v and get the most power from the panels. Granted depending on which inverter had more or less load the 48v bank would get out of balance.

why not just split the 48v bank into two 24v banks and then parallel them together and connect the same bank to both inverters?  That's the typical way to do it.

Yes you could have the inverters draw from 2 separate 24v batteries (or one giant one in parallel as tekkie said).
No you cannot use solar to power because you will have reconfigured your (1x) 48v to (2x) 24v batteries and your solar expects 48v.

You gotta pick.. do you have 1 48v batt or 2 separate 24v batt's (or even 1 if in parallel).


Unless I misunderstand the question.

Like I stated...so the charge controller will still see 48v and give max watts into the battery. If You split the bank the parallel it to 1 bigger 24v bank the charge controller would only see a 24v bank and charge accordingly.

I have like 25 12v LA batteries im just playing around with. I need to make a drawing and upload it to better explain what im saying.

So yes if your charge controller can see and charge 24v then yes it will do that.

But the whole system must see and agree upon one battery voltage... either 24 or 48. You cant have a battery seen as 2 diff voltage levels by different devices connected to it. So if you have a 24v inverter, you must use 24v batteries, regardless what your controller is capable of beyond that.

Yes, you could do that. However, it causes a whole slew of other issues. Namely, you will get massive imbalanaces between the 2 "24V" setups. You can't guarantee both inverters will draw exactly same amount of amps each. This will make the charge controller really work hard, and possibly burn it out from all the extra balancing it has to do.

I'm glad you can understand my caveman painting lol!



I figured that it would get out of balance. A bms would eleminate that though wouldn't it? I know it isn't the right way to do it but it would work.
