    Getting Solar Panels and Lithium Batteries From Sunpal Power

    Hey Thingol, I'm thinking of buying Sunpal panels. Are they still working well for you? Looks like they're UL listed but I can't find reviews on quality or performance ANYWHERE!

    Does Intertek/TUV Rheinland testing to UL standards work for USA jurisdictions?

    OR does the unit need to be tested/listed by the UL group themselves?

    Anyone familiar with Luxpower Tek?

    Are they legit? Tech looks really cool. No requirement for identical current sharing cable lengths or necessary to share batteries. https://luxpowertek.com/lxp-hybrid-3-6k

    Off grid inverter that only shares comms when stacked?

    You would need a central auto-transfer switch?

    Off grid inverter that only shares comms when stacked?

    interesting...just auto-sync to the 60 Hz signal?...that would provide incredible flexibility, BUT how would that work when connecting grid and generator for backup? The idea would be max self consumption with solar and battery and then fall back to grid when insufficient and then fall back to...

    Off grid inverter that only shares comms when stacked?

    Exactly tim, in essence it would be multiple microgrids connected...the comms would enable them to sync on the same 60 Hz signal as well as share battery state of charge

    Off grid inverter that only shares comms when stacked?

    Yeah I would want them to feed the same loads (basically just separate AC coupled systems)

    Off grid inverter that only shares comms when stacked?

    Know of any off grid inverters 3kw-12kw that only shares communications and no current sharing wires? I'm looking for each system to be "an island" independent of one another...and easily scalable.

    Question about solar panel electrical ratings

    why do do they all seem to have series of panel model with 5 watt differences?? Is that what they were tested near and they separate them into categories?

    Do most USA utilities require notice if you're going to...

    Do utilities actually agree to operate as a standby service? That'd be great. I'd totally pay a larger per KWH charge if I didn't need to pay the base rate!

    That's crazy!!

    Do most USA utilities require notice if you're going to...

    Gotcha - thats what I thought. Yeah I don't plan to ever backfeed. Only have them back me up.

    Super helpful! Thanks for the link.

    Do most USA utilities require notice if you're going to...

    Do most utilities require notice if you're going to cut the cord downstream of the service entry shutoff and wire it into an off grid inverter as a backup to a self-consumption systems with NO grid feedback? I know (and will) research with local utilities but just wondering how it generally...

    Stacking inverters in parallel vs one inverter with transformer for split phase??

    What are the decision factors/pros/cons in choosing? Residential self-consumption purposes.
