Function
Absorption time
This function serves as an additional switch-off
criterion for EFOY Pro fuel cells if the switch-off
current level is not reached within the set time
period.
This period is set by default to 3 hours, but can be
changed to any value between 0 and 5 hours.
Max. charge time
If the switch-off criteria, voltage and current,
have not been satisfied, the EFOY unit will shut
down after defined operating hours. Once the
switch-on criteria have been satisfied, the EFOY
unit will turn on again, which can be immediately
after the maximum charge time.
This switch-off criterion prevents unlimited
charge cycles caused by various factors like de-
fective batteries.
Min. charge time
The EFOY Pro fuel cell calculates the average du-
ration of a charging cycle. If this duration drops
below the present value, it indicates the error, too
old, defective or battery too small. This can
equally be an indication that incorrect battery pa-
rameters have been selected. A warning is dis-
played on the operating panel. Several short
charging cycles can damage the EFOY Pro fuel
cell and/or the battery.
Altitude up to
The EFOY Pro fuel cell is set by default for a use
up to an altitude of 1500 meter. For use at a
higher altitude for a longer period, we recom-
mend to increase the value.
Hybrid
(Switch-off voltage)
Only in Hybrid mode. If the battery voltage
reaches the set level, the EFOY Pro fuel cell
switches off, provided that the value set for the
"Switch-off current" parameter has also been
reached.
