Battery problem?

An earlier picture suggests to me that the controller is in auto-detect mode. If this is true then best to set it specifically to lithium mode.

Has always been set to lithium...

Lets wait till the batts are load tested before I buy another controller, and run cable, inside a fibreglass composite caravan. ;)

Yeah 100% . It's worked correctly at some stage. I'm just saying the long run is always a cause. I've got my panel on the roof of my car and a victron controller. Only 130w and with 6mm automotive tinned cable. I get up to 0.7v drop to the battery. Nothing else I can do. Seems to loose it with a combo of heat. Fuse holders and circuit breakers.

Has it though? What evidence is there of that? Serious questions.

Very true, I wonder how many batteries it was originally sold with?

Advertised with 2 100ah and two 170W panels, at the pickup point found just one of each... The dealer was most apologetic and asked what he could do... I asked for 3 new lead acids and they were promptly installed. Van was towed that night to Kingaroy where we stayed for 3 weeks. During that time those 3 batts were replaced with 2 x 200ah lithium Itechs, the controller was replaced with a 100/50 solarsmart mppt Victron and another 2 x 200w panels put on the roof. This setup was run until we reached Carnarvon where another Itech and another 170w panel were installed. Both installs were done by long established companies( not one guy and a ute..).


Just by coincidence, all this seems to have happened after our new fridge install, also since then the Truma LPG heater no longer works and neither does the LPG hot water......
I ASSUME its just some power cables not hooked back up, as I cant see how disconnecting something can lessen a charge... unless its an earth?

Kingaroy to Carnarvon is a long way... ;)

For a given definition of "long".

So, was it working properly in Kingaroy or do you just assume it was? If it was and it isn't now I'd be looking at something movement related, like a bad joint.

As we learn more of the ingredients of the soup - where and when did the fridge installation occur? I am assuming your assumption too...[wink11]

195l Bushman installed in Perth.
