    Hello all. As suspected, the solar panel isn't supplying any power and the leisure battery is now in a sorry state (presumably due to lack of use and hence no charging of any kind).

    I need to stump up for a new panel and battery. Before I go to the nice motorhome dealers near me, is anyone aware of any deals or discounts available for cost comparison purposes please?

    Regards,
    Lee.

    before splashing out....have you checked the voltage with a multimeter or just relying on the controllers led ?

    Could just be the controller thats not working.

    The wires on the Panel side of controller (red and black on the left of the controller) will be around 17v/18v
    Battery side of the controller should be around 13.6v in sunshine

    Cheers Pappa. Unfortunately I have used a multimeter to confirm.

    be sure to disconnect the solar before removing the battery or you could goose the controller. Chances are a dead battery may have cooked it already.

    I got my stuff from these, not the battery, there are many threads on batteries here. Do a search.

    Hi Sift, I know you've said you have confirmed with a multimeter and don't want to appear condescending in any way. Did you test at the panels waterproof junction box at all? Should be about 41v open circuit I believe. I only ask this as there is usually a diode in there and the leads are soldered to the circuit board, always worth a check to ensure the solder connection isn't broken due to vibration, or a broken cable/connection between the panel and controller. Only a thought but worth a check if you've only tested at controller end of circuit. Again, sorry if you've already done this, it's just, I'd hate to have to splash out for anything twice.

    Realistically you don't want to be paying much more than £1 per watt for a solar panel.

    I just got a 140 watt panel for £149.00 which I think is about the right price.
