The batteries sit directly on the steel base plate of the boat which is always at water temperature, so it stays very cool down there, especially when the canal freezes. In our situation the temperature sensor is not only unnecessary, but acting in the opposite direction, after all the sensor is a temperature sensitive resistor, so as the temp increases it reduces the voltage, hence if the temp drops it increases the voltage.Keith Lodgehttps://www.blogger.com/profile/03571593747071271185noreply@blogger.comtag:blogger.com,1999:blog-16640455.post-49639218718308885562011-12-31T17:30:14.636+00:002011-12-31T17:30:14.636+00:00Keith, I have a victron charger/inverter on my yac...Keith, I have a victron charger/inverter on my yacht (the Easyplus 70A/1500w) and have had a similar problem to yours with the charger starting. I found that if I disturbed the temperature sensor wire the charger started so in conversation with victron we've concluded that a new sensor is needed. I dealt with victron UK directly and they have sent me a replacement sensor foc. It sounds like you've done the right thing with your battery cables; I've 10mm cables on my setup. The contractors upgraded the cables that came with the victron when new which surprised me but better safe than sorry! We run AGM batteries (2x 255ah + engine start) so was concerned to hear of your over voltage, I don't think I've seen that problem thank goodness, that would kill AGM's in short order.<br /><br />Good to swap ideas between narrow boaters and yotties eh!
