My current setup is 300watt solar panels and 200AH (2 x 100AH) Lithium Batteries. Based on some testing over past week, the batteries will deplete after about a week because it doesn't get enough charge during the daylight hours to sustain the power draw (mainly fridge running 24/7). Fridge will dra...

Our van has been in storage for the last two years. The invertor was accidentally left on and now the batteries have zero charge. I had the power connected all day, but no sign of any charging. Are they dead? Gel batteries about seven years old, hardly used. Collo.

Hi folks, Ive just mounted a Redarc 180w panel on the roof of my new Toyota HiAce.

The panel itself is 35mm thick and Ive placed it...
