Here’s my expedient ground mount. I’ve got to get some power to cool the conex before summer. Expansion later.
Plan as follows:
3 panels per string at 38.7 volts. 1.2 temperature safety factor. 139.2 volts on Victron 150/35. Check.
9.26 amps Isc per string. 3 strings. 27.78 amps. Below 40 amp Victron limit. Check.
10 awg “solar” wire to combiner box. Midnite MNPV6 combiner with 30 amp fuses to panels and 30 amp breaker to MPPT. Right?
Victron worthy 10 awg (minimum) fine strand from the combiner box to the MPPT. And from the MPPT to the bus bar.
I have a spare Victron 150/35 and may double this array as a duplicate. Or add one more string of 3 panels. This would still keep me below the MPPT limit of 40 amps.
Any obvious errors here?
Thanks
