Wasted solar when driving - solved
(Preview)
My 2 Enerdrive 40A MPPT chargers are each connected to their own solar panel string. I did this because the panels are of different vintages/brands and keeping them seperate gives best efficiency. They can be connected as a single string and possibly lose 10-15% of their power but I chose not to. Howe...

A poor man's battery charger
(

(Preview)
From time-to-time most of us who rely upon solar panels and batteries for our energy will experience occasions when the sun doesn't shine for a few days and the batteries are depleting rapidly.

)
(Preview)
I'm currently camped at around latitude 34d south and decided, it being 2nd May, to change the angle of my solar panels to their winter setting; or from about 45d to 60d. Doing so has increased panel output by about 11% as determined from an 11am test. When I made the legs for these 4 x 200W panels I calcula...

I recently purchased a 120watt portable solar panel for use with my caravan.Today I used a multimeter to measure the voltage output and found while I was getting 20V on the input to the controller I was only getting about 2.5V on the out put side. Does the panel have to be connected to a load (e.g. a batter...

Looking to the future. We presently have 3 x 130ah AGM batteries and will replace with Lithium. Will I need 3? We have 2x 200w panels and run a small 600 inverter for the wifi. We dont have any problems of supply but of course 4 weeks of overcast and rain stretches the system. We have a 3.6kw Cummins genny as...
