    48vdc > 240vac > 120vac vs. 48vdc > 120vac > 240vac?

    I was thinking of doing exactly that but noticed fairly high idle consumption for 240v inverters. Adding an extra panel to compensate would be the usual solution but this is for an RV and I’ll be maxing out the roof as is.

    48vdc > 240vac > 120vac vs. 48vdc > 120vac > 240vac?

    I’m planning a 48vdc off-grid system with 120vac appliances. 120v inverter will always need to be on. Occasionally, I will need 240vac to charge an EV. Is it more efficient to step-up (via transformer/converter) from 120vac to 240vac when I need it, or to have a 240vac (always-on inverter from...

    Looking for 4000W 48vdc to 240vac inverter with very low idle consumption

    Hi, Looking for 4000W 48vdc to 240vac (split-phase) inverter with very low idle consumption. I know there are AIOs but they tend to have very high idle consumption so I’m thinking that a stand alone product might be more efficient? Any suggests welcome!

    Solar system for Electric Bus

    As I understand it, all 50-amp service in the US is split-phase 240v (common household) so I’d be fine with a NEMA 14-50 to J1772 EVSE.

    Solar system for Electric Bus

    IIRC, Will Prowse did a video back in Dec with two Victron Multiplus II set up for split-phase 240v and was limited to 20a (4.8kW) charging his Tesla? Seems low for the $$$ outlay. Of course, will last a lifetime… I appreciate the Victron suggests and I would totally go that way if I could...

    Solar system for Electric Bus

    None currently. Looking at adding a mini-split down the road.

    Solar system for Electric Bus

    I’m right at 1.5—105kW gives me about 70 miles. I understand I’ll be losing from the conversion although I don’t think there’s much I can do about that? Also the high idle consumption on these units. Wondering if there’s another way…

    Solar system for Electric Bus

    Looks like it’s not meant to be used off-grid?

    Solar system for Electric Bus

    Hi all, I’ve got an electric school bus I’m converting to a motorhome. I think I have a rough idea of the system that I want but I’d like some advice/opinions on if you think it’ll work and how to possibly make it better. The bus has 105kW (400v) of Traction batteries and an onboard AC charger...

    Many smaller panels vs fewer larger panels

    All things being equal, is it better to have many smaller panels or fewer larger panels? From a repair/replace perspective wouldn’t smaller panels be better/cheaper? Is there a sweet spot?
