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. That voltage is
not accessible here, but is settable in the Grid-Tie Sell menu (see page 90). The Equalize settings are also
not accessible here, but are settable in the Battery Equalize menu (see page 84).
To access the Battery Charger menu:
1. Access the Inverter menu as shown in Figure 71 on page 75.
2. Use the control wheel to highlight the Battery Charger menu.
Press the button in the center of the control wheel to accept the selection.
3. Use the control wheel to increase or decrease the set points to the correct voltage.
Press the button in the center of the control wheel to accept the selection.
This should automatically move the highlighting to the next set point.
Repeat for each set point.
4. After setting the parameters for each set point, press the TOP navigation key to return to the
Main Menu screen.
Set Points:
 Absorb Voltage:
 (Absorb) Time:
