We recently left the boat unattended for a week.
During this week away one of our leisure batteries has fried itself, returned to horrible egg smell. So I disconnected it and now have a 2 battery bank instead of 3. I will replace them all in due time.
It was incredibly hot and sunny while we were away so I assume it just over charged our bank. But surely that shouldn't have happened?
Now we have another issue arise with our inverter... It's a waeco sinepower msp702.
Basically, it's been beeping and flashing randomly when it is OFF?!! Once on it works fine, but when off it is still seeming to be a nuisance.
Any guidance greatly appreciated as this is beginning to do my swede in! Should I disconnect the solar when im going away? I have a mppt fitted, a 210w panel, 2x 110ah batteries. Everything was fine until the boat was left for the week ?♂️
