This is for anybody.
So, I'm not an electrical guy at all. But I've been reading a ton and I was explaining how the SBMS0 and DSSR20 do such a great job of battery maintenance AND you don't have overhead from and Inverter if Its off while you are charging on a cloudy day.
At which point he said. Well, if its too cloudy, it will drain your battery if the panel voltage is less than the battery voltage.
Now, I stared and stared at the schematic, and to me, it looks like the Diodes would prevent the "drain".
And of course, I would LOVE to tell my brother he is WRONG WRONG WRONG...
Please tell me I'm right.... 😁
