I have a Jayco van with a Coast to Coast TPS555 solar charge regulator and two 120w solar panels on the roof feeding two 110amp AGM batteries. I also have a 120w portable panel I connect to a Redarc BC-DC charger. The regulator on the panel has been bypassed. Will using two regulators like this have any n...

Has anyone used the 12v electric (electric only) on demand water heaters, they draw a few amps but it's only for a few minutes and I have 400 A/H of Lithium batteries, let me know, thanks in advance.

Hi All, Does anyone have experience with Dometic DRS system? Considering one of these over a Carafan due cost and no wiring required. Any pros And cons or real experience would be appreciated. Cheers

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

Don't get carried away by hype or posts about how solar will solve all your problems, it has much merit but has limitations too: 13th May 2022, 3pm, 20km north of Kerang north western Victoria: 4 X 200W freestanding solar panels facing the sun feeding into a Victron MPPT controller producing 60W as the...

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...

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...

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...

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...

Could someone tell me how to work out the energy use running continuously. Fridge is not working well and compressor not shutting off, Freezer is working fine. Lithium batteries (4x70 ah) go from 14.1 to 13.2 in about 2 hours after dark , turn fridge off and they hold at 13.2. I suspect the fridge thermo...
