Having some trouble working out why our solar panels aren't charging.
The MPPT blue LED is flashing roughly once every four seconds with no other LEDs flashing. Not sure where to start with troubleshooting.
Charger off reason in the Victron app reads "Insufficient PV power", which can be caused by insufficient PV panels voltage, loose connections, an external circuit breaker has tripped, or a fuse is blown.
I've checked all of the connections between the MPPT and the panels on the roof and we've replaced the fuses, but still not found a solution.
Any advice on where to start?
