Too complicated with two RVs and a big truck needed for them too. Decided to simplify things. So far so good :)
I know the solar and alternator charging "play well together" from PT's reporting, but I want to test for how that works exactly.
I get the 25 amps at 13.8v showing on the Trimetric from alternator charging (some of that could be from solar), but if the solar controller is set for 14.8 and only getting 4 amps, do you still get the alternator's amps? The house battery bank is at 12.3 say.
I want to test for when the batts get to 13.8 on the way to 14.8, you should lose the alternator's amps and just have the solar's amps. Then I would test for dialling down the solar to 13.8 and see if you keep getting lots of amps. IMO you should since now you are in absorption at 13.8v so amps will taper, but still be fairly high.
Anyway, there are lots of things to test and measure with the Class C, so all is not lost. :)
