2 x 100amp 12v batteries - questions
(Preview)
I have 2 x 100amp batteries in my van - wired + to + and - to - - ie to give 200amp 12v. Q1 - Should the onboard battery charger and the Solar Panel regulator be connected to the one battery or + on one and - on the other?

With no 240v connected to the van, but all wiring still on the battery, will it harm anything leaving the little solar charger on all the time? Or should I disco...

How many 'watts' will a 30amp controller cope with?
(Preview)
Gday... I have a 120Ahr battery fed by two 80watt PV panels through a 30amp controller. Given how I camp, this is quite adequate for my needs. On sunny days, even in Victoria's winter, the battery is back to float (13.4V) by late-morning/early arvo. Even on overcast days I am able to get at least three d...

Our son Cary finished fabricating the solar/LFP array on our 2002 Roadtrek 190. There are two panels: 315 W and 100 W. Since they have different voltages, he had to utilize two chargers. The cabling is run though the a/c housing and down the corner of the left rear door. The battery suite is two x 180 amp (...

We have 2 AGM 110AH batts, what I believe is a PWM controller hitched up to a single 120W panel. My question is that during the day (sunny) Im reading 14.3V at the peak of the charge, at night on...
