I have a Victron SmartSolar MPPT 100/30.
Charging a 12v Lithium from a single panel.
It used to work fine, then it looks like there was a high voltage on the PV (75.45v) and the battery (36.42v).
This might have been my fault when I was doing some rewiring and maybe connecting things in the wrong order or something.
Luckily I also have a spare SmartSolar75/10 which still charges the battery just fine, so the panel and the battery are ok.
But when I try my 100/30 it won't charge.
It shows the battery voltage and the PV voltage, but no current ever flows to the battery.
I am using the same battery settings when trying both chargers.
And using all the same cables, just swapping out the charger.
Any ideas?
