[QUOTE="condor22, post: 592005, member: 1932"] The final part of my comments - If you rely on only one method to charge a battery, the law of averages and probabilities will at some time see things go wrong. The best setups have some redundancy. These include - a DC-DC charger, 240 VAC genny charging and/or a spare charged battery, or even other lighting sources such as a headlight or gas light. Redundancy planning becomes more critical when running something like a fridge. If things go wrong here, you lose food, go hungry or cut a long awaited trip very short. I run an Engel in the rear of the 4x4 from a 100 AH AGM. I have 2 primary charging options, a DC-DC charger when driving and a 110 W panel on the roof when stopped. If solar is not cutting it, I can go for a drive. :) And before someone picks up on the fact that my panel is not 2 x the battery size, this is a deliberate "mistake". I don't have room on the 4x4 roof for a bigger panel, plus the DC-DC was the original method of charging, so I'm using a mix of methods. The key thing is the BMS (Battery Monitor), so I know what the battery is doing. I should add that as I carry a 2 kVA genset, I have other redundancy, lol. [/QUOTE]
