Adding a portable panel to roof mounted panel
I have a 160w Go Power panel (specs below) on the roof of my toyhauler fed to a Blue Sky Sun Charger 30 PWM CC. 208ah battery bank (two Interstate GC2 in series). Built in Onan 4000W generator. No ...

How many solar charge controllers do you know that can run a bulk charge of 14.6 and when adsorb hits 3%of C20 it clamps the amps and goes into a finish absorb and allows volts rise to say 15.3 then holds it fom 0 to 4 hours? (User adjustable)
Or stop charging at a set amps? ...
I know one, and own it. Infinitely adjustable - timer based Absorption, current based, you name it. Without assistance of Trimetric. The only feature that I could possibly use in Trimetric, would be its been-counting function ;) - providing theoretical SOC based on AH in/out. Have figured out that, given the location, solar size and my energy use, I will have batteries full every evening anyway, so couldn't justify buying such a nice machine as Trimetric when there isn't much need.
So far so good. Not a solution for everybody, but then, solar isn't for everybody either. Wouldn't want bright Trimetric display in my room, they at Bogart should do something about it.
Yes, I wouldn't put a 30A controller in a sealed box. Maybe doable with smaller controllers and/or in climates not awfully hot and sunny.
So your controller has a shunt at the battery so it can tell exactly what is going into the battery compared to what is bei g used by the coach? If not then its a " best guess"
