Battery Charger
IMPORTANT:
Battery charger settings need to be correct for a given battery type. Always follow battery manufacturer
recommendations. Making incorrect settings, or leaving them at factory default settings, may cause the
batteries to be undercharged or overcharged.
The inverter uses a “three-stage” battery charging cycle which utilizes multiple settings. This menu controls the
voltages and timers for the battery charger. See the inverter Operator’s Manual for an explanation of the three-stage
cycle and a description of the individual stages.
In a grid-interactive model, the Sell voltage setting is used as part of the charging cycle. The Sell voltage is not
accessible here, but is settable in the
Grid-Tie Sell menu (see page 101). The Equalize settings are also not
accessible here, but are settable in the Battery Equalize menu (see page 89).

Battery Equalize
CAUTION: Battery Damage
 Do not equalize any sealed battery types (VRLA, AGM, Gel, or other) unless
approved by the manufacturer. Some batteries may suffer severe damage
from equalization.
 Contact the battery manufacturer for recommendations on equalization
voltage, duration, schedule, and/or advisability. Always follow
manufacturer recommendations for equalization.
The Battery Equalize menu controls the settings for the equalization process, which is used for battery
maintenance. See the inverter Operator’s Manual for an explanation of equalization and how it relates to
the regular charging process.

Set Points:
 Absorb Voltage –Adjusts the target voltage of Bulk and
Absorption stages.
 (Absorb) Time –Adjusts the duration of the Absorption stage.
 Float Voltage –Adjusts the target voltage of the Float stage.
 (Float) Time – Adjusts the duration of the Float stage, once the
voltage has been reached.
 Re-Float Voltage –Adjusts the point at which the Float stage
begins again.
Set Points:
 Equalize Voltage – Adjusts the voltage of the Equalization cycle.
 (Equalize) Time – Adjusts the duration of the Equalization cycle,
once the voltage has been reached.
