Default Battery Charging Question
Ok heres one for all the techies, which I am definately not.

Fitting 2 new 110Ah batts tomorrow and a Ctek charger. Next to my battery box is a 600watt invertor whic I use regularly and it works really well. My question is can I run the invertor to generate 240volt then use that to charge the same batteries that are driving the invertor. This would save starting the genny or finding a mains hook up and would be a perfect solution no noise no fuel. I guess the answers are either;

The invertor would overheat
The charging process through the invertor will take out more power than it puts in
Or something else a layman like me has'nt thought of.

I need to ask because it keeps going around in my head and in my simplistic way of looking at things it should work, but I bet it won't.

Sorry Rory, in laymans terms.....dont be daft

the inverter will take out many times what the charger will put back in just to run the charger

certainly would Rory

i once had thoughts of a starter motor, powering an alternator, charging the battery used to run the starter motor.

but as Chris said...perpetual motion doesnt work like that
