I forgot to update this thread, sorry. Mentioned it in other threads.
The high set point is also the float voltage till dark. The high can go to 15v, but on mine that actually got me more like 15.4 due to that calibration error mentioned above, so I was able to use it to equalize.
The amps reading agreed with multimeter and Trimetric so that was on for calibration. I never used the AH counter on it, no need in my set-up.
I was using it with the 130w panel while the Eco-W is on the 230w panel. With both controllers set to get the same voltage they added their amps no problem.
I have since sold the 130w panel but kept the Solar30 in case I ever get 12v solar panels again. I really like this controller.
