Mppt rs 450 max 10.8kW

so I have 3 strings 9x450w panels

I read the rs450 has 3 x 4kW max and 11.5kW total max

but maybe you will hit that 11.5kW across 4 strings if you had 3kW on each

cause mine maxes out at 10.7kW. 2 of the strings reach peach 4kW and 3rd string is 3.3kW. it’s not a panel problem cause the charger alternates from time to time which of the strings to reduce by 700W

so not sure if that’s normal or bad setting or needs update

I have dc charge limit disabled

Datasheet claim 11.5 kW at 57.6 V.

ok I understand, wasn’t aware was voltage dependant

to me doesn’t make sense rating at a voltage batteries are full :rofl:

should be at a voltage most people actually charge at

no big deal thanks
