375W Huawei Optimizer

One for every solar panel connected to the Huawei inverter. Provides rapid shutdown compliance and also performs the MPPT algorithm per-panel (good for partially shaded arrays).

Gauranteed to work. I have not tested every optimizer but the ones I’ve tested have worked and have just a few KWH of usage. Not gauranteeing how many KWH has been pushed through them but I do gaurantee they will be perfectly operational when they arrive.
