Bevor ihr Panels kauft, denkt dran, dass die Leerlauf-Spannung über der Maximalspannung des Akkus (36 Volt Akkus haben 40 Volt, wenn sie voll geladen sind.) liegen muss.
In Reihe schalten würde ich nur Panels mit gleicher Leistung.
Leerlauf-Spannung des Panels 23,4 V
passt also nicht zu
Maximalspannung des Akkus 25,2 V ?

My battery and it's charging "station".

The Reaktor chargers accept from 11 to 18v DC so in theory I could plug one into a 100W 18v PV panel and even with losses expect to charge my battery (2 x 6S6P) at between 1A and 3A. For using one charger with both batteries I have a parallel charger board.

I chose these chargers and the battery configuration a long time ago but even then I was planning on a solar PV option :giggle:

You can see why I would like to leave my power supply at home when on the road, it must weigh 2.5 kg... I originally had a PC power supply that was hacked to output 12v but after a certain time it popped because it couldn't handle the load. There is a rather expensive (compared to above) AC/DC charger that "only" weighs 1.2 kg.
