I am currently looking to expand our off grid system as we ran out of power over Christmas last year. Our current system has 4 x 405w panels in 2 strings on a 150/60tr. This is feeding 4 victron 12v telecom 200ah AMG batteries wired in series/parallel to give 24v 400ah 9800wh (4.9kw useable storage) we have a Phoenix Inverter 24v 800.
I intend to add 3kw of extra solar and the ability to monitor the system remotely. The EasySolar-II 3kVA MPPT 250/70 GX looks like a good fit connecting the 150/60tr with a ve direct cable. This unit will minimise the wiring. My question is will my current battery bank handle the extra current draw from the Easysolar -II 3kVA? The current battery setup is wired in 35sqmm.
Thanks
