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 ๐ ...

took license with BFL13's data for us single 100 ah or less battery users to illustrate that 1A ticklers take a very long time.

That graph is a generator charging. When solar controller gets voltage to ABS, it will stay there 60 minutes (typically, in cheaper controllers), and then current drops to a trickle.

Westend is too humble. His roof-mounted hinged 2-axis tiltable contraption is elegant, check the pics on the list of installs.
