Connecting A Solar Panel To A Caravan Battery

In the functional diagram below you will see the diode symbol in the line from the dc external input.

Connecting a solar panel to a caravan battery.

To power a dual battery system you ll need to connect the panels in parallel. When the battery is full the charge controller will stop delivering energy to the battery. Charge your 12v battery from a solar panel and have your backup powered. For using portable solar its more effective to connect directly to the caravan camper battery through a quality mppt solar charge controller.

Connect the negatives to the negatives and positives to the positives. Connecting two solar panels in parallel. Wiring the battery to the charge controller. The charge controller also senses if the battery is full.

This process allows both regulators to detect the battery voltage type charge conditions etc without the pressure of applying the charge. This is why you can t connect your solar panel directly to your battery. Reconnect solar panels to regulators. Reconnect both regulators to the battery on their own no solar panels connected.

The thickness of the wire will depend on the type of charge controller you get. The same thickness wire can connect the regulator to the first battery. Then connect the regulator to the 12 volt battery. The majority of regulators have particular charging profiles for various kinds of automotive batteries that are used these days commonly.

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. Have a anderson plug setup for this purpose. The only efficient option for adding solar charging to yout battery in a jayco van is to connect it directly to the battery. If you have a shunt for battery condition monitoring then connect the anderson through this to monitor the additional solar charge.

Leave for 15 minutes.
