Is there any reason why this might not work?
Camper has two solar panels on the roof and an Overland MPPT controller for two AGM 12v batteries. Is it possible to cable an additional AGM 12v battery to the outside SAE Solar port on the rear of the camper to provide additional power to the controller?
In other words, the two existing AGM batteries are running down and there is not enough sun to bring them back up. Would a 3rd battery plugged in before the MPPT controller provide charging power. (it would already be fully charged) Could this be incorrect due to 12v being fed also towards the two roof solar panels.
The battery would be inside a battery box mounted on a rear cargo rack in the event that the two house batteries run low.
Thank you,
