Connecting A Solar Panel To A Caravan Battery

The same thickness wire can connect the regulator to the first battery.

Connecting a solar panel to a caravan battery. Charge your 12v battery from a solar panel and have your backup powered. In the functional diagram below you will see the diode symbol in the line from the dc external input. Leave for 15 minutes. To power a dual battery system you ll need to connect the panels in parallel.

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. Have a anderson plug setup for this purpose. Then connect the regulator to the 12 volt battery. 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.

This is why you can t connect your solar panel directly to your battery. If you have a shunt for battery condition monitoring then connect the anderson through this to monitor the additional solar charge. Always connect your solar panels via a regulator. The charge controller also senses if the battery is full.

Reconnect both regulators to the battery on their own no solar panels connected. The only efficient option for adding solar charging to yout battery in a jayco van is to connect it directly to the battery. This process allows both regulators to detect the battery voltage type charge conditions etc without the pressure of applying the charge. Wiring the battery to the charge controller.

The thickness of the wire will depend on the type of charge controller you get. The majority of regulators have particular charging profiles for various kinds of automotive batteries that are used these days commonly. Connect the negatives to the negatives and positives to the positives. If both panels are rated at the same maximum voltage then you ll get maximum output.
