I have a Victron SmartSolar MPPT 100/30.
Charging a 12v Lithium from a single panel.
It used to work fine. In the history it looks like there was a high voltage on the PV (75.45v) and the battery (36.42v), and then no charging since then.
Luckily I also have a spare SmartSolar75/10 which still charges the battery just fine, so the panel and the battery are ok.
I am using the same battery settings and cables, just swapping out the charger.
When I try my 100/30 now it won't charge, even on a nice sunny day when the 75/10 does charge.
It shows the battery voltage and the PV voltage, but no current ever flows to the battery.
I have tried restoring default settings, disable/enable charging, temperature options disabled.
I did use the disable charging option before and am wondering if that is stuck off despite what the software says. I've tried turning it off and on again though. A hard/factory settings reset would be great but I don't think that's possible?
Or maybe something got fried inside from the high voltage surge? I guess not the fuse or the voltage sensors but maybe the MOFSET?
Hope you can help.
Thanks!
