Operation
Float Cancel Voltage

If the battery bank discharges below 11.50 Volts (23.00 Volts @ 24 V, 46.00 Volts @ 48 V) the
previous night, Float charging stage will be cancelled for the next charge cycle. Figure 4-5 above
illustrates this concept. At 0:00 hrs (dawn), battery voltage is below the Float Cancel threshold
voltage. The diagram shows where Float stage would have occurred if Float was not cancelled.

Equalize Timeout
event. The timeout timer begins as
soon as battery voltage exceeds the Absorption voltage setpoint. If there is insuf
fi
cient charging
current or system loads are too large, the battery voltage may not reach the Equalize setpoint.
Equalize Timeout is a safety feature that prevents high battery voltage for extended periods of
time which may damage the battery.
