I need some assistance here, any inputs appreciated;
1 X Victron EasySolar-II 48-3000
1 X 100Ah Lithium ION Battery
8 X 360W Canadian Solar PV panels facing true North on 25 degrees roof (I'm in South Africa) (4 X Series + 4 X Series, 2 X Series pairs connect in parallel to EasySolar using 6mm2 cable)
I played around with the PV Panels, when I disconnect 1 X Series string the MPPT max out at 1220W with Battery charging, Essential loads + Loads on 6000W (Running ESS) This is quite acceptable.
The issue is both Series strings paired in parallel, get MAX of 1800W from MPPT. In fact over the passed week I got 1800W MAX from the EasySolar over 24-hours.
According to my calculations I should get around 2300W from the 8 X 360W PV Panels.
The EasySolar is equipped with a 250/70 MPPT, and is rated at 4000W.
Any thoughts on why I'm limited at 1800W on Solar power?
