Mppt 250/100 stopped suddenly


Here’s a screenshot

Been working fine until this morning. I changed from 6 panels on 1 string to 5 panels each on 2 strings. It seemed to work this morning for a couple hours and then just stopped. The connections are all good, I checked a handful of them. So weird to work for 2 hours and then stop


I’ve tried

turning off the batteries and back on

2 Quattro 10kws I’ve turned on/off

Restarted cerbo multiple times

Pv combiner box on/off

The fix was to remove all power from the mppt restarting it and it works. Stupid victron! I wish I had ac today

It looks like your PV voltage has exceeded 150v, which for a 150/xx controller must never occur.

Are you sure that its a 150/70 and not 250/70? Pretty sure its a 250/70, otherwise there would have been at least a PV voltage warning


58.2V on the battery sounds like the BMS could have stopped the charging, or maybe disconnected the battery

I’ve restarted everything. No CBs are triggered. Not sure what to do
