Safety
1a) If more PV power is connected, the controller will limit input power.
1b) The PV voltage must exceed Vbat + 5V for the controller to start.
Thereafter the minimum PV voltage is Vbat + 1V.
2) A higher sort circuit current may damage the controller in case of reverse
polarity connection of the PV array.
3) Default setting: OFF
4) MC4 models: several splitter pairs may be needed to parallel the strings of solar panels
