Hello,
Since a few month I changed the old diesel engine for a waterworld electric engine. I have a charge Skylla Titan 48 25 see below
To charge the 8 12v batteries they installed a transformer 48-12v, see below
Now that the weather is quite bad in The Netherlands the boat is mainly staying in the harbour. Should I unplug it when I am not using it or can it stay always plugged-in?
I want to avoid a huge electricity bill and to destroy the batteries.
My concern is that the screen connected to the engine that calculates the battery pourcentage left and the autonomy never shut down. So if unplugged it is possible that it still think that the batteries are charged but it got emptied by the screen and the bilge pomp if it starts.
Thank you for your help in trying to understand how it works.
