Battery Charging

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.

Figure 5 Charging Stages Over Time

All voltages in this section are given for a 12-volt system. For higher-voltage systems, the voltage can be multiplied by the appropriate amount. (Factory defaults for each voltage are shown beginning on page 47.) Set points can be adjusted using the system display (see the appropriate manual).

The inverter uses a “three-stage” battery charging process. The three stages are Bulk, Absorption, and Float. These stages follow a series of steps, which are marked on the chart above. The points where the dark line intersects the vertical dotted line indicate a change from one step to the next. A circle indicates that the inverter has switched to a new target voltage. A square indicates that the inverter has reached the target voltage (a horizontal dotted line). A triangle indicates that the inverter has acquired a new target voltage, but is still inactive. (See Figure 6 on page 21.) The process shown here also includes the step of selling power to the utility, as this is integrally tied with the battery charger.

The Target Points and Time Limits cited under various steps are settable using the system display.

No Charging

If the inverter is not charging, any of the following conditions may apply:

¾The unit is inverting or not connected to a qualified AC source.

¾The unit is connected to an AC source but is in a mode or stage that does not use the charger. (Silent mode is one example.)

¾The unit is connected to an AC source but the charger has been turned off.

Bulk Stage

This stage activates the charger. This is the first stage in the three-stage charge cycle. It is a constant-current stage which drives the battery voltage up. This stage typically leaves the batteries at 75% to 90% of their capacity, depending on conditions.

Target point: absorb setpoint or Absorb Voltage setting. The default is 14.4 Vdc (in a 12-volt system).
