Connecting A Solar Panel To A Caravan Battery

The majority of regulators have particular charging profiles for various kinds of automotive batteries that are used these days commonly.

Connecting a solar panel to a caravan battery.

The same thickness wire can connect the regulator to the first battery. When the battery is full the charge controller will stop delivering energy to the battery. Then connect the regulator to the 12 volt battery. Charge your 12v battery from a solar panel and have your backup powered.

The charge controller also senses if the battery is full. Have a anderson plug setup for this purpose. Wiring the battery to the charge controller. If you have a shunt for battery condition monitoring then connect the anderson through this to monitor the additional solar charge.

This process allows both regulators to detect the battery voltage type charge conditions etc without the pressure of applying the charge. To power a dual battery system you ll need to connect the panels in parallel. Just plug mine into the solar socket 12v fused 10amp in battery box socket wires connect to the wires from battery before 12v fuse distribution box. Connecting two solar panels in parallel.

This is why you can t connect your solar panel directly to your battery. In the functional diagram below you will see the diode symbol in the line from the dc external input. If both panels are rated at the same maximum voltage then you ll get maximum output. The instructions that come with the solar regulator will identify the wire thickness required depending on your distances but rv applications normally use 6mm square uv stabillised wire connecting your solar panels to a solar regulator.

Reconnect both regulators to the battery on their own no solar panels connected. Leave for 15 minutes. The only efficient option for adding solar charging to yout battery in a jayco van is to connect it directly to the battery. Connect the negatives to the negatives and positives to the positives.

For using portable solar its more effective to connect directly to the caravan camper battery through a quality mppt solar charge controller.
