How reliable are my charge controllers 'State of Charge' Indicators?
Hi everyone,
We've just had our solar system set up, however I am running into an interesting situation.
We are plugged in to shore power all night right now which is charging our batts to basically full. Then we have had direct sunlight all day (unplugged).
Our Tri-star PWM 45 amp controller flashes green and the manual indicates that means we are at 80-95% SOC (state of charge)
However, within maybe a few hours of the sun going down the charge controller is indicating 0-35% state of charge.
Has anyone experienced this? I'm struggling to find information online.
