Solar Panel wiring
Last night I built a solar panel rack, mounted a 20watt 1amp panel, and installed a charge controller rated up to 4amps.
Now I am about to go run the wires. I have two 12volt batteries hooked up in parallel. The alternator from my engine also runs to my batteries and I have a battery charger for when I am at the marina. Here is my question:
Once I have the solar panel hooked to the battery (coming from the charge controller), If I plugged in my shore power battery charger would it cause an issue? And for the sake of this question assume that the shore power battery charger also has a built in charge controller.
Also, the alternator will not cause and issue, right? So I guess my question is:
Can batteries use multiple charging sources simultaneously? I have been told to never run the engine and have the shore power battery charger hooked up at the same time. So, I never tried it so I dont know if it would do anything.
