    Do I need a PV fuse? 9s2p

    The EG4 6000xp has a PV disconnect switch on the outside. Will that do the trick?

    Do I need a PV fuse? 9s2p

    I've done a bit of research and I understand that with just two strings combined I can get away without a PV fuse. Panel specs are in the attachments.

    Build check: 6000xp, eg4 powerwall, 36x 280 watt yingli panels

    I plan to have a bare wire going between all the arrays on the roof and just trying to figure out where to tie that wire into

    Build check: 6000xp, eg4 powerwall, 36x 280 watt yingli panels

    My roof has just enough room for strings of 10 but I thought maybe that would be too close to the maximum voltage (VOC 45v x 10 panels) gets me to 450 of a 480 volt limit. Would that be a problem or should I get as close as possible to the limit with out going over. I'm buying these panels...

    I have 36 Yingli panels (280 watt) I have and eg4 6000xp and the eg4 battery on the way to me. Planning on running 4 strings of 9 panels to stay under the 480v limit of the 6000xp. Should I add a combiner box or a fuse to each string or will the 16 amps per MPPT be fine. Also-- I have seen a...

    Superstrut Gold Galvanized-- how does it hold up to the weather

    My local home depot sells superstrut gold galvanized. Here in Hawaii things rust pretty fast. Superstrut advertises how good their gold galvanizing is but I wonder if anyone here has used and how does it hold up to the weather.

    Trying to pick an inverter for some EV charging and other misc loads (Dryer)

    I have 36 panels at 280 watts each. Picked these up really cheap. I just got a chevy bolt and I'd love to charge for free. Looking at inverters/ mppt now. I'd be fine just charging the EV in the day and skip over the batteries. Would something like the Growatt MIN 6000TL-X work just to...
