    Hi, i am a new member and would like to know if anyone new the basics of wiring a solar panel into my Rapido.
    I know the + & - wires go from solar panel to the regulator and then to the battery.
    but there are then some more terminal connections on the drawing, showing connections to lights etc. "load 1 & 2 ?
    am i right in saying you dont connect to these ?

    Depends on the controller and what you want to do with it, but for basic battery charging what you say is 'perfik' and all you need to do :thumb:

    the extra two terminals, usually marked with a light bulb, will provide a very low current of around 2amps at most to feed back from the battery through the controller at night for a porch light etc..

    not worth the trouble wiring it in.

    be sure to cover the panel so it is not live when doing the wiring connections

    simple mistake to short it out

    when you get round to fixing the panel to the roof make sure you tape the exposed ends of the panel wires or cover the solar panel with cardboard/towel/sheet etc......in sunlight they can carry over 17volts and if shorted together may damage the panel.

    Fitting a solar panel for Scotland. Now there's optimism. Is it to run an electric midge zapper ?

    I wired my spare terminals to a 12v ciggar socket and charge my phones and torch for free:thumb:
    It should be noted these spare terminals will only be live when the batteries are full,ish, when they drop below a certain threshold the regulator will cut supply to them and send all available charge to the leisure batteries, when full again any spare power is sent back to the phone/torch socket, as John said at about 2 amp max:Cool:

    Oh dear :Doh:.....sun oil (along with any perfumed toiletries) attracts the little buggers and midge cream is pretty much useless.

    if you have the time buy a bottle of Avon 'skin so soft' skin cream/softener (blue-ish green label)

    the Army/SAS use it when on manoeuvres in Scotland, so it must work.

    Not usually the case, loads 1 and 2 are for connecting everything up to the total wattage of the controller, then when the battery falls to a preset level those loads will be disconnected to protect the battery. I run my TV, sat system and inverter ect from the load rather than direct from the battery. Not only do you get protection for the battery but you also get voltage spike protection as it is a regulated output. These facilities are usually ignored but they are there for a purpose. The Rapido does I believe could be wrong I often am) have a Schudlt electrabloc fitted to handle all of the electrics in the van that being the case it is possible to get a matching regulator to plug straight into the electrabloc rather than connect straight to the batteries. The advantage of this is the ability to charge the engine battery as well as the hab battery.

    is it ok to just bed the solar panel down on silicone, it has an aluminium frame about 1 1/2" I have a plastic junction box siliconed to the roof above the wardrobe for the wires to go through.

    may be the case on some Rogr, but the controller on the kontiki had a max load of 2 amps and only worked when the panel was 'dead'...ie night time.

    basically if the panel was producing power it switched off the aux output....hence me saying it is for a porch light etc.

    I cant see that its been mentioned yet But..
    Connect the regulator to your leisure battery FIRST, leave it on a few mins and connect the solar panel last..

    The reason for that John is the contoller used was intended for automatic lighting rigs, however there is a setting Number 6 if memory serves correctly that allows output all the time and you could use the red button to switch on and off if you held the button down for a longer time it would change the programable settings for automatic varying lengths of light on. Cheapo controllers not original intended for motorhome use. I did run my TV etc though one of those in the old beast. But even then output was the same as controller was rated at. 10amp From memory, I still have the paperwork so will look it up.
