Outback Power Systems 80 user manual

BULK cycle provides the maximum power to the battery –the voltage increases while recharging.

A Bulk cycle is automatically initiated when the battery voltage is below the Absorb and Float* recharge voltage set points. The Bulk cycle will continue until the Absorb voltage set point is achieved. MPPT Bulk is displayed on the screen.

ABSORBING cycle limits the amount of power going to the battery—the voltage is held constant.

The Absorb cycle will continue for the duration of the Bulk cycle or until the 2 hour (default) Absorb time limit is reached. For example, if a Bulk cycle takes 1 hour to reach the Absorb voltage set point, then the Absorb cycle will continue for 1 hour as well. However, if a Bulk cycle takes 3 hours to reach the Absorb voltage set point, then the Absorb cycle will continue for 2 hours only. A Bulk cycle will be re-initiated if the battery voltage is not sustained at the Absorb voltage set point. Absorbing is displayed on the screen at this time.

FLOAT cycle reduces the recharging voltage to prevent overcharging of the batteries.

A Float cycle follows after the Absorb cycle is completed; Float is displayed on the screen. The FLEXmax 80 will not re-initiate another Bulk cycle if the Float voltage set point is not sustained*. FMPPT is displayed. However, it will continue to recharge the battery until the Float voltage set point is reached.

*A Bulk cycle can be auto-initiated if the battery voltage falls below the Float voltage set point and the Re-Bulkvoltage option is set.
