I originally wired my two 100 W panels in parallel and got almost zero input, display kept flickering as the voltage was too low. After reconfiguring them in series to get ~36–40 V open‑circuit, the AC70 happily pulled in 400–450 W under peak sun. Charger stayed rock‑solid, and I went from 20 % to 80 % in just over an hour.
