Solar to leisure battery

[paulfr]

We have a 200w Dokio solar panel and would like it to charge the Leisure battery for a few days.The battery is an AGM LP100.I am led to believe that the regulator you get with the panels are not the best,so thinking about the victrons........the question is which one?

100/20 will do the job nicely!

Cheers mate..........The 100/50 that i was looking at.........not got a clue on the numbers!.....seemed a bit expensive for a box!

The 100/20 will be most suited to that 200w panel.

100 part means the max panel voltage - 100v
20 part means max charge rate - 20A

Make sure you get the SMART version that had blue tooth, the cheaper blue-solor don't have the feature.

Solar PWM & MPPT controllers - How I Done It -

There is a lot of talk about Solar at the moment, and with spring not to far away i wanted to go over the whole Solar controller thing.

The main components are the Panels themselves, the charge controller (whether that be stand alone or integrated into a DC-DC charger) and of course Battery's.

In this thread we will show the main Solar controllers and they can and cant do . . .


Power, energy and capacity
Power in watts (W) = current in amps (A) x voltage in volts (V)
Energy in watt hours (Wh) = power in watts (W) x time in hours...

Cheers mate,bought the 100/20 and also a couple of the Battery Monitors.......Never thought of that sort of thing,Usually let the leisure and main get too low.
