Hi again,
Thanks to all who have replied. I agree with everybody that we shouldn't use so much electricity, 12v DC or 230v AC, but no one has answered the question in the last para of my OP.
Can anyone tell me if it would be a good idea to let the batteries sit for a time before starting up a generator to continue charging them when we moor up and stop the engine?
We are liveaboard, have a stirling alternator to battery charger which show 160 Amps when charging low batteries. I intend to fit a Smartguage system, and I've worked with electronics and electricity for over 50 years but have no real experience of battery powered systems.
Regards,
Keith
