Hi all,
Hoping for some advice about wiring up a dcdc charger and solar setup in my camper trailer. In particular about earthing it.
I am using a redarc bcdc1225d charger with the hope to charge a lifepo4 battery from the car when driving and via solar when camping. The charger needs to be close to the aux battery so will be mounted in the trailer. That also allows me to use the mppt charger for the solar while u am out and about in the car.
The earthing does my head in. I can never quite get my head around earthing to a chassis and then connecting the chassis back to the negative battery terminal. What is the point?
More specifically about the job at hand:
1) Should the negative from the solar panel earth to the trailer chassis? Or is it fine to run it straight back to the negative terminal on the auxiliary battery? In my old setup (charging an AGM battery only fro. Solar) I simply ran the negative cable from the panel to the battery. Was that dodgy AF?
2) I assume where running in a trailer the black lead should run back to the vehicle (planning to use anderson style leads). But what does that mean when the vehicle isn't connected and the system is running from solar and bits j pieces drawing from the battery?
Grateful for any advice. Taking the kids camping and don't really want to electrocute them (not sure they'd appreciate even a mild 12v wake-up)
