Hello,
I am having trouble with my boat's battery system. The issue is that the battery bank is running out of power very quickly. I have recently purchased a sailing catamaran with a set of four Delkor M31 lead calcium marine batteries. The bank seems to run out of charge very quickly once disconnected from shore power, for example, the enerdrive inverter for the 240V power system has an alarm which sounds with a "low battery voltage" error after not even fully charging a phone battery fully through a 240V outlet on the boat. We have not experiences the 12V power system running out, i.e. the chartplotter, lights and autopilot have never had issues offshore.
There is also a solar panel system with victron bluesolar mppt charge controller. We have got the bluetooth dongle for this system and upon analysis have seen that the battery bank is going back to the bulk stage of charging every day, spending about 4-5 hours charging the batteries back up to the float stage. Is this normal to be happening? As when offshore we are left without 240V power for most of the day unless we run the engines to charge the batteries faster. We also have an epower battery charger, should this be left on whilst connected to shore power or run whilst offshore? I am new to this world and not totally certain about how the 12V/240V systems work/interact. The batteries are not too old (5 years or so) I am at a loss for what could be causing this issue. Any sort of help or tests we could do for these issues would be fantastic to hear. Please let me know if you need any further information.
Thank you so much. Lachie
