    Taking a look at solar charge controllers and notice most have 3 pairs of terminlas to connect cables to them.

    There are a pair for the solar panel input. There are a pair to charge the leisure battery, it's the pair labelled "Connected Load" (icon usually a light bulb) are the ones I don't understand, can anyone enlighten me please?

    Hi. I use ours for lights etc. It's basically a 12v supply ... :thumb:

    Thanks yet again.

    If you use those terminals as a 12v power point, and in your instance lights, how does that work after dark with no power input, or is 12v then drawn from the battery via the controller?

    As above, that's correct. Only for lights or similar - not for connecting inverters and suchlike! :Smile:

    Since read again in full the link you sent, it's advantage as a source of 12v power is the battery low voltage cut-out built in to the controller.

    Thanks SC

    it is a regulated 12V supply so ideal for voltage sensitive items. when the battery voltage drops too low the supply is cut off thereby protecting the batteries.
    I have my inverter connected to the regulator, it runs my TV, satbox and DVD player total current draw seldom exceeds 5 amp and the 20 amp controller. So everything is safe.

    Just beat me to it Roger .. and was going to add...

    Saying not to connect an inverter is a bit of a blanket statement. Better advice would be, do not exceed the stated maximum current of the controller ..
