Batteries overheating seems to be coming more of a problem over the last few years. It is obviously due to being constantly connected to some form of charging, but is the charger mains, solar or wind and does the controller fail or the battery from being constantly charged?I have secured or zipped up the occasional canvas canopy or closed a window with no thought given to it. As said the owner would not have been aware .
Earlier this year noticed a not very loud beeping alarm from a boat so I notified the marina . The marina notified the owner. It turned out to be a gas alarm caused from a battery which was gassing and overheating. The marina disconnected shore power . The owner attended and found a very hot battery. He brought me a bottle of wine which he didn't really need to do but it was well received. I didn't climb aboard but surely people would like any fault noticed by others to be actioned.
I have about 120 Watts of panels feeding 2 times 110ah batteries via a victron mppt controller. In theory the batteries could take the panels direct but I didn't like that.
Should I pull the fuse on my set up when not on board much during the winter ?
