Fridge technology / efficiency
(Preview)
Hi, I have an old (20+ years) engel 40 litre upright danfross compressor fridge. My question is how much have compressor fridges changed over the last 25 years? Do newer fridges use less power, better cycle times, better insulation etc. to warrant replacement? Th

Victron Solar Panel
(Preview)
I have two 155W solar panels on my caravan roof and wanted to add another. As I couldnt get one of the same make from the van manufacturer I bought a 175W Victron panel which has very similar specifications. However, Victron do not make solar panels so it will have been rebranded from another manufact...

Where is the best place to parallel identical panels?
(Preview)
I've recently purchased another panel that is as close in specification as the original as possible. Connecting them in parallel, I'm thinking the best place to do this is just before the controller, using the same cable as before. A friend suggested using those "Y" connector cords but I see issues w...

I have a Trayon slide-on and recently upgraded my batteries with two lithium 100ah set up in series. I keep it all charged with a 250w solar panel. The resultant 200ah of stored power is ample to run the fridge (2.5ah), water pump, diesel hot water and lighting for weeks, but because I do a lot of remote ca...

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...

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. If, like me, you also carry a generator you have an option to put some additional charge into the batteries f...

Questions - solar charging

Hello everyone, My use for DC power in our caravan is quite low - a couple of LED lights, the TV & very occasionally the pump. I have recently added another 55w solar panel, in theory giving me 110w. Having had the gas struts regassed has certainly assisted in lifting the roof - one reason why I kept th...

Solar panel angle

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...
