Featured Replies

im new into solar n trying to learn. (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))

The arrows next to the screws does not follow the legend in the insert at the top. Difficult to say which one is right.

On the bottom one is the B40 an indication of 40A?

? They do seem to for me. 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.
