Thanhs for the info everyone.
I,ve got a sterling advanced digital 4 step switch mode charger , what ever that all means.
I,m sorry if I didnt make myself clear. Most of my charging is done by the engine,s 100 amp alternator but once a week or so I bung the genny on to do my washing and hoovering.( I know, but I,ve got a new springer pup)
The battery bank is 440 and after about 2 hours cruising its down to about 3amps going in, then if the genny go,s on, it gets below 2 then onto float. I do sometimes flick the charger off then on and I do get a bit more going in.
My main power usage is a 240 telly on freesat. I,m thinking about changing to 12v but would need a freeview tv and new aerial unless I go down the 12v freesat tv which is around £400, I think.
My tv at the minute takes about 4 1/2 amps including the inverter.
Cheers, Paul.
