I am in a very conflicted dilemma. So I have both of these inverters and can proceed with either one? BUT I am torn as the best approach for my system, which can change like the river flows down hill.
I own a Sunverge Cabinet, it has a SE XW+6848, a Sun verge control etc. and KOKAM 11.6kwh of lithium-ion batteries. I don't want to use these batteries because when I bought the battery unit it was at a very very low charge voltage of just 1v on these NMC pouch cells. I have charged them cycled them a little, and waited out some discharge but so far after 6 months they are holding, no noticeable swelling. This is a super professional build and it turn key, so why would I use it since we are DIY! Here is a picture with some of it pulled down, for clarity. Also have the Conext gateway for battery coms. The Sunverge stuff probably would go and I would control it directly with the conext gateway. This unit was brand new and never used, but they blew the FET's on the inverter and I had it repaired.
I also own a DC Solar Trailer with (2) SMA Sunny islands 6048, 1080ah of FLA, 2Kw worth of solar all wired up ready to grid tie backup etc. I have used this several times since the California power outages have taken place. I can pull 60amps 240v AC all day long with this setup. I have planned on using my Lifepo4 bank to power this trailer and cabinet once finished.
Over the last year I have been building a power wall that will end up around with 29kwh or so of Lifepo4 cells. Mostly upcycled batteries and a few new ones. All using a Seplos BMS with CAN and RS485. Seplos will emulate a Pylontech battery BMS so I can connect to this via can for both the SMA and SE XW+.
What does the brain trust think? I am impartial either way.
Ohh side note I have a SolarEdge Grid tie system that would go into the approximate sides on the inverters. Max backup functions of the inverters would meet my loads, except AC which I would run on these either way.
Which one should I punt?
Thanks for any input!
