Hi guys hope someone can help as pulling my hair out here, I have a 120w solar panel & victron mppt controller that goes through Sargent ec500 on my Autotrail.
All been good for a few years then intermittently getting no solar, have checked the panel on the roof 24v & 4 amps today in sunny conditions here in Cumbria so all seems ok with the panel, connected panel back up and checked the wires from the panel down into van just before i connect to the victron mppt and the same 24v & 4 amps here's the problem as soon as I connect back the the victron the volts go down to 12.5 on the connections this is the same if the victron is connected to the ec500 or not, how come the voltage drop ? The battery is fine only a year old , I have even bought a new Victron as thought it must be that but the readings are exactly the same, it has not charged on solar for 6 weeks I took the van to a local auto electrician and you wouldn't believe when I pulled up at the garage all was fine solar charging great, he checked everything out couldn't find anything wrong and charged me for 30 mins , as soon as i got home I checked the solar and not working again !!!!
