Solar upgrade, what to expect
With the help of several of you on this forum, I made an upgrade to an mppt controller, 300 watts of solar panels, and added two more house batteries. Who hoo! Charges like crazy!
I have a couple of questions as to what to expect with my new system.
Both house and chassis batteries always read very close to the same. When will the isolator isolate the chassis battery from using any more electricity so that the engine will always start? Are things working right?
With the power off to the house, my system charges the batteries to 14.something in a hurry. Even with the frig off, the system charges to 13. something. So, is the Magnum the main drain culprit? If so, has anyone added a cut off switch?
Running the frig only, what kind of a draw will this make?
Please, for the sake of this newby who's electrical prowess is limited to switching out a light fixture and plugging in a toaster, speak in terms of battery readings 12.4 from 13.7, etc.
Thanks for any use info you can share. With your help, I've come from wanting to cry and push the thing off a cliff to actually enjoying a trip!
