Absorption phase time = 0.38 × C ÷ I

• C = 20 hr rated capacity (total AH capacity of battery bank)
• I = Maximum available charging current provided by the PV source. This value can be calculated for different charge controller types as follows:

PWM charge controller maximum available charge current = parallel strings × ISC

MPPT charge controller maximum available charge current = Total PV source power rating ÷ nominal system voltage

This number may be limited by the programmed maximum charge rate for the charge controller or by the maximum output current of the charge controller, in which case that value should be used.
