When I received my AC200P I topped off the change to 100% with AC. I then discharged it to 96% testing out the various outputs.
I then hooked it up to 3 SP200s in series to charge verify that the solar charge was working. I tested each panel for volts and was getting around 24V each. In series I was getting 70V. When I hooked up to the AC200P, the charge started and showed 71V but quickly dropped to around 40V. Also, the Watts ran around 210 - 220. I would have expected more.
Is this because the unit is close to fully charged and starts to pull less energy? If so, at what discharge level might I see the full use of the watts available from the panels?
I want to test to make sure all is good.
