Re: Solar heating element for water heater
You're putting major juice to the batts with the engine when charging the fridge - not the 170w solar. Dunno what your alternator and regulator system is...
560 worth of regular or agm batts are probably worth 170ish amps usable (not going below 50%) unless you are running the engine overtime to get them past 20% long wall of charging.
The only way you will have 'overage' solar with 240w solar will be because of engine charging.
Just a thought....
Why do you think your batts are full....what tells you that?
