I'm putting in 800W solar with a Growatt 3000LVM 24v charge controller/inverter. I'm changing to a 24V system so now my generator is going to be relying on just the starting battery. I already have problems keeping if fully charged when I'm out because I keep my dashcams recording while I'm camping, so I know I need to keep the starting battery fully charged. I don't want to run a junction to the generator & starter battery by tapping into one of the 12V batteries because they will become unbalanced (but I will have a battery 'normally off' battery switch split between my 2 house batts to use to start the generator in case the starting battery ends up dead somehow).
I will be installing a stepdown DC converter from the house 24V converter in order to power the house lights & refrigerator, but I'm thinking that if I just run a wire from that to a battery isolator that goes to the starting battery it may draw more than the rated 40 amps every time I start the RV.(?) But I also think that maybe if the starting battery is fully charged all of the time then maybe it won't draw much current.(?)
The easiest way I can think of to do this is to just use my house AC to power a 12v 3A trickle charger? Would it kill the trickle charger?
Other questions I have: When my starter battery has dies in the past all I had to do is start my generator and that would jump start my starter battery. So is the DC power panel what did that? If so, is my 40amp step down converter going to handle it anyhow? The wires are definitely too small I think they are 10ga at best. I'm stuck, please tell me what I am missing.
Thanks,
Dean
