I'm wanting to have a solar system for off grid living. I've already acquired 21 solar panels at 190w each, and a grid tie inverter. I know I'm still needing a hybrid inverter 3-5kw range, and a lipo4 battery bank.
I was looking to see if I might get some advice on the system setup. First off the grid tie inverter is an ABB 4.2kw,
model# PVI-4.2-OUTD-S-US-A
I've heard that a grid tie inverter is a good option to have in an off grid system. Providing efficient AC and being able to lighten the load of the hybrid inverter when panels are producing? The ABB inverter was included with the panels when purchased, so I just considered it a bonus if what I heard was true.
I was leaning towards a SPF 5000 ES
Growatt hybrid inverter, but didn't realize that it's 230V until the other day. Not sure if it would be worth the extra time and money to make it 110V, or just go with a different inverter?
I'm wanting to be able to run a small 115V mini split, mostly in the summer. 1 maybe 2 RV refridgerators to run ac in the summer, and propane in the winter.
The battery bank I was thinking would be a 48V lifepo4, consisting of four 12V 100ah 1280wh dr prepare power max batteries.
I also thought of going with a diy battery bank similar to the 280ah 12V bank built by Freely Roaming on youtube. Just adding more batteries to achieve 48V, and 400ah+.
I've also got a hydrogen appliances wind turbine that I will want to feed into the system too. Its a 12V DC turbine, that I'm contemplating the 48V DC upgrade.
I'm not an expert, but not the first time I've built a off grid solar system either. Any ideas thoughts advice etc would be greatly appreciated. Thanks
