The absorption period also ends when the output current of the solar charger
drops to less than 2Amps, not because of low solar array output but because
the battery is fully charged (tail current cut off).
This algorithm prevents over charge of the battery due to daily absorption
charging when the system operates without load or with a small load.

Note: divide all values by two in case of a 12V system and multiply by two in
case of a 48V system.
