As always, the misleading chinese. Will explore others, thanks.

Thank you ! Something like this, for a single 40V 400W 10A panel to a plain lead acid 12V battery ?? Or this ?

Apart from my solar system, I have an automotive inverter (12Vin) but no 12V out panels. And several ~40V 400W good leftovers...

Hello. Say you own a big utility company that generates electricity from hydroelectric, diesel, whatever and serves the whole town...

Unclear to my brain :(... If I inject 100KWh into the grid and get credited for 75KWh; the utility sells, bills and collects the 25KWh...

Greetings. At my residence; all my solar grid-tied generation fed into the grid gets 100% credit for the same electric rate consumed...
