I am doing my first ever trip without hookups for 4-5 days. I expect pretty low power use (reefer, water heater, and the occasional light only). Over the years I have collected some solar panels, all intended to charge
12v. batteries (3 are VW supplied units for keeping car batteries charged while away, and one is intended to run a solar water heating circulating pump).
They all put current into a test set up, with the 3 VW units, paralleled together charging at about 0.45 amps. The other unit puts out about .5 amps by itself.
Can I "gang" these all together (connect in parallel), connect directly to the batteries, and count on no damage and a higher charge rate? Or will the weaker ones somehow lessen the stronger one?
Thanks,
Don
