Thanks.... I can see there's more to this than meets the eye! Nothnig's going wrong, but I'd like to unplug from the shoreline, and start using the boat as a boat, and it's be nice to sit and watch the telly at night without the engine running!!

Hi Thanks for the advice so far. You've pretty much worked me out. I plugged into the mains, switched the inverter on to charge onl, and forgot about it. The only problem this gives me on a day to day basis is that the batteries don't have enough kick in them to start the Webasto. I was hoping to take the boat out and about during the summer, which is why I'm now considering doing something about it. You've probably guessed a lot of the technology passes me by, but I'm very grateful for the warnings.

Hello I've been living in my 10 year old boat for two years, plugged into a shoreline. If I unplug I lose all 240 power, but the 12 volt appliances are ok. If I turn on the engine, the inverter will run the lights and TV etc, but will trip immediately for a heavy duty item such as a kettle. As soon as I turn the engine off, the 240 cuts out. The inverter has a low battery light which lights up from time to time. I'm pretty sure the batteries are done, but am nervous about buying new ones in case the inverter is faulty. I'd hate to buy new batteries and wreck them by discharging them if it turned out the inverter was at fault. The inverter is a Victron Phoenix 12v 3000va 120amp Would appreciate any thoughts!
