I have a van with 3 x 100W fixed solar panels in series charging a 150ah lithium battery via the Victron 100/20 SmartSolar MPPT charger. I am considering adding the ability to charge whilst driving, so looking at adding the Orion-TR Smart 12/12-30A DC-DC charger.
I am a bit confused on the logistics of these two units working together however, with the solar fixed to the roof and potentally giving full output when driving in good sun. Is it fine to wire these two in parallel and let them run simultaneously when driving?
Anything I might be missing here?
