Hi guys, I recentrly installed an Axpert King, with 12x400W panels on the roof and 4x200aH batteries in series. I have noticed putting the dishwasher on, that it is still pulling from batteries, but the load is below the 4800W im expecting from the roof. Im new to this, so did they install it correctly, or am i misunderstanding how this works? I live in Durban, and its a cloudless day with our famous Durban heat
