(sorry im from non-English spoken country) i ve been using 1kw AIO inverter for a while bcs fan noise n want to hv more load i upgraded to 5 KW AIO inverter This 5kw one. i know fuse currents low n want to use till get proper ones. here s wht i have. PV have 4 280w in series. my load would be ~120w This first MCB is this one 500V dc @16A Second MCB is for battery to AIO inverter (from local suppier it was intented to use for e-mopeds. (pic s not clear it writes 12-100V= 350-1000W)) So if those polarities are correct? Thnx for help

Difficult to say which one is right. On the bottom one is the B40 an indication of 40A?

So @occuplus, I believe that you have the wiring correct. These things are so confusing for most electricians, that they are actually banned in Australia, I believe.
