3.7 Battery charging information
The charge controller starts a new charge cycle every morning,
when the sun starts shining.
Default setting:
The maximum duration of the absorption period is determined
by the battery voltage measured just before the solar charger
starts up in the morning:
Battery voltage Vb (@start-up) Maximum absorption time
Vb < 23,8V 6h
23,8V < Vb < 24,4V 4h
24,4V < Vb < 25,2V 2h
Vb > 25,2V 1h
(divide voltages by 2 for a 12V system and multiply by two in
case of a 48V system)
If the absorption period is interrupted due to a cloud or due to a
power hungry load, the absorption process will resume when
absorption voltage is reached again later on the day, until the
absorption period has been completed.
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.
User defined algorithm:
Any setting change performed with Bluetooth or via VE.Direct will
override the rotary switch setting. Turning the rotary switch will
override prior settings made with Bluetooth or VE.Direct.
