    Default Do I really????

    Do I really need to get the victron 15a smart charger or can I get a smaller amp victron charger.
    Which one will work to keep my 105ah deltec charged in my camper.

    You don't really need a Victron for that size unless you are in desperate need to burn some cash

    75/10 - R1,580
    75/15 - R1,755
    100/15 - R2,143
    100/20 - R2,667
    100/30 - R3,900

    Can't find anything less than 10amp. To be honest, not sure that saving from 10 - 20 is worth the compromise, nor the 75 vs the 100 volt. Those are the blue solar


    Smart

    75/10 - R2,163
    100/15 - R2,738
    100/20 - R3,117

    R550 in it, I'd be buying at least the 100/15 - personally I have the 100/20

    Just my thoughts... I've got the 100/20...but I only have 2 x 100w panels connected in series, which I use to charge my 24v lifepo4 battery... That means I've only seen a max of 8amps being used for charging. So if you've got bigger panels and push more amps, great. I'm in the process of getting the Orion-Tr 12-24 that gives 10amp charging. And I'm happy with that capacity of charging.

    I do get about 13 amp charge rate when I charge a 12v gel battery with the same 2 panels connected in series

    Here's some more info at post #10

    Nothing is going to handle water - make sure it's completely waterproof in a halyester housing of some sort.

    You need to balance charge input (100w - 7a max) , charge efficiency (PWM vs MPPT), battery size (105 from 50% SOC is 50amps, 5 hours at 10a, 10 hours at 5a). If you're drawing 5a from 16.30 to 07.30 (10 hours) you're going to, simplistically, need 10 hours at 5a to charge the battery back up. So 100w is too small, and 5a too small.

    Maths time.

    What is the estimated draw
    What panel do you have for supply
    Where do you intend to camp (Average usable sunlight)

    Then 10amp will be fine, since if you can charge batteries on mains then you can also run the fridge on mains. Your only issue is travel time, then fit a cable to charge the spare battery via the alternator

    I have 7 A intelligent but I needed an other. I took that 15A Victron. In a hurry it charges that 105 A battery (same as mine) quickly (Had this case already one time when we had to leave van to PE). I keep both of the charges out of rain: under semi closed bonnet, in front cone or now inside the van.

    I went full monty. I have the IP65 15amp charger and it's a pleasure. But then I also have lithium, whick sucks it all up.

    For in car I have the Orion 30 amp, and for them sunny days a SmartSolar 100 | 15 (untested).

    I also have a SmartShunt, and that is a magical device, specially for lithium.

    The fact that most of these components have built-in bluetooth also raises the bar.

    FWIW. I have the NL 5A charger and its not enough in my circumstances.. At the two camps we stayed in in Kgalagadi, power goes off at night at 10, back on at 5... Running two engel fridges, the charger could not keep up.. So I am getting another one, at least 10A.. I will use the NL at home where cycle time isnt a factor.

    Hi Fatbike,
    I have a compass off-roader caravan/trailer.
    I have 2 x 102ah batteries installed. I have a 230/12V 25A victron ip65 charger for when there is 230v power. I then have a 330w solar panel strapped on the roof with a victron MPPT IP67 100/30 solar charge controller.
    when we offgrid, I run 2 fridges 72l campmaster and the batteries are fully charged by about 14h00 the next day.
    The victron is simply one of the better chargers available that takes care of your batteries. If you want a smaller size just be sure you will have enough sun to recharge everything. For me the few extra hundred rand(about R350-R400) between the 15A or 30A wasn’t an issue.
    I have been caught with limited sun for a day and a half and have not struggled.
