I said I assumed I need a BMS, my question is more of which kind and if the kind I need matters depending on which inverter I get. Yep I am new at this and I knew I was going to diy the batteries shortly after starting to read up on things as its half or less the cost of prebuilt ones and I am a diy kind of person. Also I am not separating the cells, just cutting the bar to remove 4 of the cells from the 20 cell packs. The extra 4 will physically remain and I will connect those 4 extra from each of the 4 modules to make a 5th 16c pack.
My loads are a well pump, shop with some 15-20 amp 220v circuit equipment, like a table saw, dust extraction, air compressor etc. 5 small mini splits (1 ton max each), 3 in the house and 2 in the pole barn. As of now the water heater, stove, dryer are on gas, I may swap them in the future. I figured the eg4 18k would be sufficient to start with or if there are other inverters that can connect to the panels, grid, generator and batteries and seamlessly swap between them I would consider those as well.
Thank you!
Congratulations on the modules. I have four of these now that I am working on.
Check out my post I have in these forums, on doing exactly what you plan to do.
