Hello,
i load my PPP40 via Car 12V or Solarpanel (switchable, all poles) via the car/solar input. Last summer i noticed that my PPP does not longer load properly when connected to Solar. While under perfect conditions a max input power of 90Watt was reached, it is now about 50W. The input voltage drops down to 10,6V. That isn't normal, right? I am quite sure it was above 13 volts before but i can't remember the exact value. I recently replaced the solar panel but the defect is still there.
My suggestion is defect in the batterys input. Does anone have an idea what else it could be or how to test it better?
Regards,
Marco
