Anderson plug to 12S plug.

Hi there,

Thinking about my new solar battery charger - and will make my own Anderson to 12S connector - thanks all!

Have found this combo just now - any good? Trying to choose between PWM & MPPT controller - any thoughts?

200 Watt 12V Fixed Solar Panel for RV, Caravan, Campervan, Camping – Oksolar

thanks in advance

cheers!

I bought a secondhand house roof panel for $20, added a cheap PWM controller that came as a freebie with another panel I bought and an assortment of wire and connecters. It only gets sun for a few hours a day and can be connected to the car for up to a week. Keeps it nicely topped up.
It works and for the price, very hard to beat. Its not the most efficient and is self regulating by the amount of daylight it gets; I keep the D4, a battery box and two large wet cell batteries charged just by swapping the Anderson plug to each battery. On the D4 it plugs into the Traxside rear access point. The regulator is always plugged into one battery or another.

I also have another secondhand house roof panel which is just wired into the Ctek solar access point on my camper and that is also working great. The solar panel attached to the roof of the camper does not get any sun where it is parked so it is just bypassed.

Both setups have been in use for almost 12 months now without a problem. Except for the D4, where LR accept 75% as fully charged, there is no high or extended discharge on the batteries so they are in a top up cycle for a few hours each day. I have never tried to measure the output of the regulator, but I did make sure that it was rated above the output of the solar panel.

Regards

Is the pwm rated for that voltage, most cheapies will only do 12/24V and 10a or so.

Yep, that's what I meant by checking the regulator specs, the panel must match the reg or the other way around depending on what you have in your shed. You have to look at the panel voltage and amps on the sticker on the back of the panel to make sure the reg is ok.

Remember, I'm using second-hand panels probably close to 10 years old, they are not rated as high as new panels today which at pretty much double the old ones.

By memory, the reg was good for 20 amps and up to 40 or 50 volts.
