Hi all, I am having an issue with 2 x 200ah ATG slimline batteries purchased but I'm not sure if it is actually the batteries, or related settings, and I know you guys are Victron gurus.
My Victron setup consists of 3000/12/120 Inverter, 100/50 MPPT for roof solar (2 x 180w Enerdrive Panels), 100/30 MPPT for Portable Solar (ATG blanket), Lynx Shunt, Lynx Distrubutor, Orion XS 50a DC Charger and Cerbo GX with a 70 screen. After finally putting it all together, and setting it up I think correctly, it's been running ok, system only runs a 130l Bushmans Upright, 2 x 40l EvaKool drawer fridges, couple of USB outlets and some strip lighting for the canopy, all running off a touch switch system. Problem is, when I switched all 3 fridges on the other day, it stated the ah draw was between 6-8ah (one drawer fridge running as freezer) and was at 73% on the Cerbo screen, however shortly shut down with no power at all from anything, even running a test light across the terminals produced no result.
I ran a charger via anderson plug input linked to the Shunt/Distributor which bought everything back up, then ran power to the inverter to initiate charging and left it overnight/next day with no draw on the system. At 6am last night I switched the 3 fridges on and overnight to 9am it dropped to 73% on the Cerbo again, then when I changed the charged voltage setting from 13.7v to 14.2v it dropped to 39% on the Cerbo screen.
I leave for a Cape York trip in a day for a month and am now worried something is seriously not right with the system, I've put the batteries back on charge through the inverter, and attached are the current settings through the Cerbo battery bank menu, note I cannot change the Peukert exponent at all, but it might be because I am running the Beta V2.0 Gui? Appreciate any help or insights you can give, they are non Bluetooth batteries, so I'm kind of stuck here.
