Searching for appropriate Solar Charger
Just upgraded my 2013 Jayco Swift 18' TT with dual 6V batteries and LED lighting .. Now I'm looking for a "Very Portable" 100Wt Solar Charging system .. I've read many forum posts where folks talk ab...

Because the OP is running GC2 batteries, he will need an adjustable voltage solar charger that is programmable and capable of 15.0V bulk charge rate at the battery terminals to run in conjunction with his solar panels.
And fat wire, 10 gauge, and a short run of wire from the controller to his batteries, 5 feet or less.
The goal is 100% state of charge, not 97%, or 98%. Hard to do with 1 ah or more constant parasitic loss when the fridge is on propane and the circuit board is on constantly.
Adjustable setpoints means - a charger other than the one included with the kit.
1A parasitic loss - I think it's 1A, not 1AH 'cause 1AH per 24 hours isn't worth talking about - does make 100% SOC difficult, with 120W panel. It's all about energy usage. If you only use 30 AH in 24 hrs, then 120W panel would bring it up to Abs at upper 90-s SOC on a good day, and - if needed - would keep on pumping more amps than 1A parasitic plus 1 or 2A of some odd small load like fan or TV, until it's 100%.
Seems like the store run out of 120W kits - good. Didn't like it anyway :) ...
