Operation
Lead-Chemistry Batteries (Three-Stage Charging)
When selecting a
Battery Model
for a lead-acid, AGM, or similar battery, this cycle is generally
used. The three stages of this charge cycle are Bulk, Absorption, and Float. These stages are
introduced in Figure 27 and described beginning below.
The following items describe the operation and intended use for each individual charging step as
shown in the graphs. Note that some charging cycles may not follow this exact sequence. These
include cycles which were previously interrupted, and also customized charging. Each step
describes how to defeat or customize the step if specialized charging is required.
See page 58 for a description of multiple three-stage cycles when the charger is restarted after the
cycle is complete. This page also describes multiple cycles when the charger is restarted after
being interrupted.
For battery types using three-stage charging, all selections under the
Battery
tab on page 49 can
be edited or customized.
Manual Start
In the
Action Menu
, pressing
Bulk Start
will initiate a charge cycle, beginning with the Bulk stage.

If the inverter is not charging, several conditions may apply:
The unit is not connected to a qualified AC source. If a generator is present, it may not be running.
The unit is connected to an AC source but the charger has been stopped. See page 25.

Entering Bulk:
Upon pressing

(see above), or upon initial battery power-up and initial
connection of grid power. Any subsequent connection to the grid will only enter the Bulk stage if the
Rebulk point is reached. (See page 59.) Otherwise the charger will return to its previous stage.
