Hi guys, Is there a way to connect my new inverter to the grid but guarantee the power company will not see any back feeding so they won't know it exists? Is there a device I can connect in between the grid and feed that would take small loads that the inverter might put back towards the grid...

So we'd asked our local golf course if they had old golf cart batteries last month. At the time I was looking for some batteries to put into our newly acquired Toyota ECOMS mini EV. But I've since already found exact replacements which are working well. I also ordered 26 lithium blade cells...

Later Edit: Well, I just measured the incoming line from the pole at the main breaker. It's not 200v after all. It's 102v. I could have sworn it was 200v from when I measured it several years ago. Guess not... So that is the answer right there. This is only one leg from the pole feeding this...

Hey guys, Not sure where to put this. Mods, please move as appropriate. So we have five vendors visiting this week to give us proposals for a total system install to include panels, inverter, batteries, and even V2H options. I wanted to share a few worksheets one of the vendors provided for...

Hi, So I'm considering these panels for home use here in Japan: LR7-72HTDR 600~625M https://static.longi.com/LR_7_72_HTDR_600_625_M_30_30_and_15_Frame_20240527_V2_9cb60497fe.pdf I don't see anyone here really talking about 600+ volt panels. Why? Why is the US and/or residential not using these...

Hey guys. First post. I'm rebuilding a used Toyota COMS (ToyoBody) EV. Upgrading the 6 lead acid batteries to lithium. 72v system. Looking at a JK-B2A24S20P BMS. That a good one? Anyway, so far I think the EVE 100ah 3.2v LF100LA cells may be a good bet to replace the six dead Panasonic...

Hi guys, Second post. I'm in Japan (100v 60hz) and am researching the best inverter brand and model to buy for a DIY solar build. I intend to connect a Leaf 24kWh battery to it for home storage. I'm a member of Dala's EV discord group but have additional questions. So far I've been able to...
