    Default Adding Solar to National Luna Power Pack

    Hi I want to add 2 x 55W solar panels and a WRND charge controller to my dad's NL power pack (built-in solenoid).

    Can I just connect the charge controller into the Grey Brad Harrison on the NL Power pack and move fridge to the Hella?

    Any advise or recommendations will be much appreciated. Dad Solar.pdf

    This is what I was thinking of doing.

    Or should I rather go straight from the solar controller to the battery (fused)? Click image for larger version.

    You can yes, as the grey plug is a direct feed to the battery. If you however use this plug as an output then just connect the controler to the battery and bypass everything

    I cannot see a reason not to do it that way. But I would remove the solenoid and run the alternator charging through the WRND as well - then you have DC-DC charging. The WRND is very good.
    Everything is a hammer.
    Unless it is a screw driver.

    Then it it a chisel.

    No do not use the grey plug on the box. You have to connect the solar panels to the wrnd and the battery on wrnd direct to your battery. The reason being that the panels sense switching and assumes the same voltage as the battery. Very extended charging resulting.
    Attach a seperate bh on the side of the box to battery . or drill a hole on the side and connect wrnd bat side direct to battery .

    This is only a solar charge controller not the DC - DC model

    Your controller should have a fuse.
    But I would saya 15 amp fuse should suffice for 2x 55 watt panels. If connected parralal.

    I see you are in Durbanville. Speak to Pieter v Eeden also on forum.
    He is also in D,ville.
    He procured a Wrnd for me, and he has other uses for his.

    Kind regards
    Coenie

    I bought a solar controller from 4x4 direct.
    Screwed it onto my Luna box and ran wires directly to battery connect solar panel via bh plug.

    As per your diagram the grey bh plug on the left. Mount that directly below the wrnd. Plug your panels into this.
    The output from the wrnd wire directly to the battery terminals. Fuse according
