My 600 watt PSW inverter has PWM internally included. But now I believe I have discovered why it was on special. Reading the specs it says that maximum PV power (W) is at 400 W @ max current of 20 A.
My limited understanding is that this inverter will restrict me to a maximum of 4 x 100 watt panels as at that size the cumulative parallel current will be near the max.
Question is can I use another PWM fed from another separate 400 watt array into the same battery array as that of the inverter? And so on.
Would the fuse between the battery positive and the inverter need to be upgraded?
760W panel array, 4 x 6v 220 ah Crown batteries, Tristar TS-45 PWM controller, no name 600 PSW inverter.
