Float Transition Current - BLUE SKY IPN ProRemote Installation And Operation Manual

Blue Sky Energy – IPN ProRemote

Float Transition Current

"Time in Absorption" is an accepted method to determine when the battery is fully charged if net charge current is unknown. A preferred method
provided by the IPN ProRemote is to use net battery charge current matched to battery size in amp-hours. With the IPN ProRemote the charge
controller will consider the battery fully charged and to switch to Float if net battery current drops below the Float Transition Current setting while the
battery is at the Absorption voltage setpoint. The factory default Float Transition Current setting (Float Current in the Battery Charge Parameters menu)
of 1.5 amps per 100 amp-hours of battery capacity is suitable for most batteries. With the factory default Battery Amp-Hour setting of 220 amp-hours,
the battery would be considered fully charged when net battery charge current decreases to less than 3.3 amps while at the Absorption voltage setpoint.
To assure that net charge current is what determines when the battery is full, Charge Time should be increased to approximately 4 hours. This is so that
if battery current is unable to decrease to the Float Transition Current due to battery age or damage, charge will terminate after a reasonable time
period.
