Solar Panel for 16' Bambi

[DRowell]

One other consideration. I put a toggle switch between the solar panel POSITIVE lead and the charge controller so that I could work on any of the 12V electrical system and not have the solar panels energizing it.

There is a pre wired lead in the closet for a Victron controller monitor that, for factory solar, is installed by the water heater control by the sink. I think the other end is under the panel in the curb side bed platform where it can be connected in some manner to the electrical panel, I think. That is not needed since the phone app bluetoothed to the Victron SmartSolar MPPT 100-20 Charge Controller will give the equivalent info.

Of note, the charge controller can be set for lithium or other types of batteries. The charge and float voltage for lithium is higher. I have a lithium battery and the full charge voltage runs between 14.2V and 14.5V. After pulling the trailer for a day with no power usage the voltage ends up at 13.2V to 13.5V, a lead acid battery full charge. I assume that the car charging system which is set for lead acid batteries "siphons off" from the lithium battery until the voltage matches the car battery's. I have not found information on this.

Good info. Thanks Don
