I have been reading van magazines and they are saying that you can fit lith. In place of agm batteries without changing any equip eg solar controller, recharger. Any comments advice please.

I want to replace the two 100Ah AGM house batteries in my caravan. I can disconnect the CTEK charger from the batteries, but they would still be charged from 3 roof top solar panels via a 30 amp solar charge controller. I want to stop the panels from charging the batteries before I disconnect them for rep...

when fitting this controller do I need to input any parameters? We now have 3x140ah lithiums ready to install. TIA BAS

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

Victoria, in the forest but decent panel/sun coverage. 800W panels, 210Ah AGM, Victron electronics. Needed to run the generator today for three hours to support a fridge/freezer. Solar has a lot of positives but it is not perfect - do not allow internet forums to convince you otherwise.

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...

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...

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...

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...

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...

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...
