Grape Solar 40A PWM controller
Hi all, Decided it's time to get into solar! Got a Grape Solar 40A PWM controller and a single 100W panel for starters. My batteries are 2 Trojan T105s. Have some questions about setting up the ...

here is how the controller profile works using the 'terms' of the controller.
solar charge the battery until the batt = boost charge volt(v)
Maintain boost charge volt(v) for the boost charge tim(min)
Maintain float charge volt(v)
on the 28th of each month, after boost charge time(min) do the equalz(v) for equal time(min).
While in float mode, return to boost (start over) anytime the batt v drops to boost char return(v).
so set boost to 14.8 and on a normal usage day determine if 2hrs is short, if so increase 120 to something bigger. Set eaual to whatever you like that will not damage your equipment, default is every 30 days for 60 min. Not sure if you could set it to daily (every 1 day) to match your charge profile.
you would also need to set the first 2 parameters higher for your equal v.
