EASUNpower?

I did get a response from them and they confirmed it works with two in parallel split phase. I asked them to send me a manual.

Which inverter did you get? the 24 volt or 48 volt

Yes, curious about this too. According to the spec sheet, 24V can't do split phase, but the 48V can (if I read the specs correctly).

@AZ_Tekkie: so did you end up going with the 48V inverter? Definitely looking forward to the manual, too. Maybe it won't be a "generic" one that is for all models.

Oh i'm on the mpp solar 24v inverter. I'm just looking to see what's out there for an upgrade. Also from what i've found it's only the 24v that does the split phase. Haven't seen one of the 48v models that does it. Still waiting for them to send the manual.
 
Here's the manual for the hybrid 24v that does split phase with two in parallel and appears to support up to 9 inverters if i'm reading right.
https://www.dropbox.com/s/94j72d532i7lhcc/IGrid SV LV 3KVA manual 20170712.pdf?dl=0

When the units are operated in 2-phase

application, please choose 2PX to defineeach inverter.
Its required to have at least 2 inverters
(one inverter in each phase) or maximum 9
inverters to support two-phase equipment.
Please refer to 5-2 for detailed information.
Please select 2P1 in program 28 for the
inverters connected to L1 phase and2P2
in program 28 for the inverters connected to L2 phase

I got the 48v of course. That was the whole point as I couldn't find a 120v/60Hz (American) version that did 48v batteries from MPP.

Also, not that you asked, but both WatchPower and SolarPatrol seem to work fine with this inverter (all the brands are voltronic hardware right so why wouldn't it). I'm still trying to figure out how to get a Rasp Pi to pull telemetry data from it so I can put in InfluxDB/Grafana. I saw this thread (https://secondlifestorage.com/t-Esperyd´s-Raspberry-PI-project) but still not sure how to pull raw data from USB in Linux (my unit only has a USB port not an RS232 port). I think it has something to do with hidraw or pymodbus or something. Still learning all this IoT stuff.

I'm guessing there's no way around a dedicated 24/7 computer connected to the USB port to ensure I'm not missing any data right? Or does the device have it's own ability to store historical data for you to retrieve when you reconnect?
 
I'd go with a unit and manufacturer that has a good track record like Outback, Magnum or Schneider. Guess I need to look into EASUNpower...
 
Well don't take what I said as an endorsement yet. I said it's working for me "so far"... less than a week is hardly proof of quality. :)

But it seems to me that if I were to have issues it would be pretty immediately, so it's probably going to be fine.

BTW... does anyone know if/how I can put more charge controllers onto this inverter (in case I do want more panels)? Is that even how it works? Or do I just connect charge controllers to the battery bank and the inverter also connects to the battery bank and just draws from batt and doesn't care what the external controller does?

I ask because I never actually bought a charge controller, this inverter comes with one builtin.
 
That's all great and wonderful, but it's still only 24V :s I hope they get a 48V out soon

Looks like Mppsolar updated their website with the offering.

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.
 
Progress, slow as it may be.
 
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 two24v banks and then parallel them togetherand 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.
