    The controller is actually the "cheapest" component of the kit, although it is quite a robust little device. It is a 20A PWM controller and can be bought for as little as R350 at some outlets.
    It is not integrated into the solar kit and is simply attached to the back of one panel. One is able to connect via the controller or simply bypass it if you have something like an MPPT.
    Never a bad idea though to have it as a spare, even if you have a trusty unit such as Victron, especially when you're in the gramadoelas.

    Yes Deo is correct. Under ideal circumstances the 200W offers 10.47A of current so one is more likely to average been 8 and 9 amps.
    The best I have personally been able to get was 9.3A (midday and cloudless).

    Morne, the best to answer that is to work the sums. Formula you should use is T=Ah/A
    T - Time
    Ah - Ampere Hour rating of battery (yours is 102Ah
    A - Current in Amperes.
    If we assume you get 10A from the panels it means your charging time (from empty) will be 102Ah/10A=10.2 hours
    But you are most likely never to sit with a completely empty battery. Even if you effectively only have around 5-6 hours per day for sun charging the 200W will be more than ample to keep your battery at full charge even with a fridge on a hot day.

    I have a 20A victron charge controller.

    We have ordered some of these caps with our next shipment. It should be available early next year.

    Munnika

    Thanks for the great service
    Sent your details to my dad looking for 200w foldable
    He spoke to you and was happy with the feedback

    We will test his current system over Dec but I am sure he will go for the 200w foldable after that

    I see that the Anderson plug rear cap is available from Camp Craft https://www.campcraft.co.za/power/pl...-cover-sheath/ and Lumeno direct. I have no idea if Camp Craft is a reputable website or not

    Buy from Munnik.
    I bought one when I visited the kids in Australia.Same quality,only diff. is that it concists of 10 small panels but otherwise identical.Works well and is so practical.Was always carting two solid panels,but that is really cumbersome.
    Problem is they don't ship to ZA,so Munnik is providing a good service!!!

    Hi Andrew

    Would I need 2x sets to charge a 24V setup(i.e. 2x in series, with my existing Victron MPPT Smartsolar controller), or will 1x set suffice, i.e. output voltage of 1x panel enough?

    Cheers.

    Always connect the controller to the batteries first to let the controller know whether its 12v or 24v

    Your Victron MPPT Smartsolar controller will automatically read that its 24v and act accordingly.

    Check the controller's specs for max volts and amps and add panels. On a 24v system two sets of 200w will work well.

    On a 24v system you might want to connect the panels in series, but check the specs first.

    Spot on Deo.
    The foldable models can technically be connected in series but it has not been designed for that purpose. These foldable models are manufactured with preconfigured cables and Anderson (or Brad Harrison) plugs designed for a 12V setup. With a bit of basic rewiring of the cables and plugs it is possible but not advisable.
    The 100W semi-flex panels we do are different in that it does not come with a controller and is much easier to connect in either parallel or series. It is supplied with Solar MC4 connectors.

    Another thought I would like to test here..
    High-end monochrystalline panels, especially panels not intended to be fixed to a structure like the roof of your vehicle or van, is a rather big investment. Very often trips are planned where there is need of a mobile solar unit and you really only need it for that trip.
    Would you think being able to rent the panel for that period is feasible? Perhaps on a day rate, with the usual deposit and "I'll find you if you break it" clauses?
    Logistics might be an issue as we are based in Cape Town and would find it difficult to service the rest of SA.
    Thoughts?

    It may be worth your while partnering with vehicle rental guys... It will afford you the coverage as well as the admin.
    Rental is a definite option though.
