Hi, I'm looking to setup a off grid system using Mikrotek 2KW/36V MPPT Solar inverter with Okaya lithium ferrous phosphate batteries. My query is, how many lithium batteries should I connect to this system? The options available are 12.8V/80Ah |12.8V/100Ah | 12.8V/120Ah. Battery support by inverter is 80Ah to 200Ah. Can I connect 3 batteries of 12.8 V/100Ah in series. I have attached the tech specs for the inverter as well as the battery. Also, would connecting 2 solar panels of 395W suffice for charging the batteries?
