    Hope someone can help here, I have an Epip20 solar charge controller and I am stuck with a few things.
    As you can see in the pic it has 3 LED's, OK there easy enough BUt the switch on the right of the unit can be pressed on/off, when I press it it lights up red, press it again and it doesn't light up.

    So do I have it pressed ( red light ) or not to have it charge my batteries ?.

    Mine is a different make but has a similar switch which cuts the solar power when lit up........easy to check with a multi meter

    It is usually on when the red light is on but to be 100% sure simply put a digi meter across the leisure battery when the sun is shining

    Turn on one of the living area lights

    Press the button and see what happens to the reading

    Press again and see what happens to the reading

    When it starts to rise ( proly only by .1 or .2 volts to start with ) you know it is working and charging :thumb:

    If you have not got a digi meter pop along to somewhere like Halfrauds and get a wee cheapy .. Around a tenner will get you something usable and useful for all manner of jobs :thumb:

    off.....

    the switch will turn on a very low power output (maybe 2 amps) to run, say, a single lamp directly from the controller rather than from the vans control panel.

    basically back feeding power from the battery to the solar control switch then onwards to the lamp or whatever is connected.

    if you look on the controller there are 6 terminals...the two on the right are for connections for this function.

    If it's like mine.....light OFF for charging

    If your battery goes flat you know you got it wrong

    Our's is on, has been since it was installed by a Fun member, we have never lost power, and have used Aires extensively this year, without loss of 12 volt power.

    Hope this helps

    as i said, the switch has nothing to do with battery charging....only to switch on a low amp supply FROM the battery.

    doesnt make any difference whether its on or off to charge batteries. :thumb:

    Yes.

    flashing green is charging and solid green is fully charged.

    from memory, yellow is either a faulty or discharged battery, only shows if its dark or no sun and the batteries have been flattened.

    Another question,
    Is is OK to have this charge two batteries ?, i.e. the two batteries that I have on the motorhome. Since the batteries are linked for longer use I would have thought the solar can charge both just as the normal charging system does.
