PRO-Verter Charger Mode Status Messages
When AC power (utility or generator) is connected to the PRO-Verter, it automatically begins to
monitor the AC input for acceptable voltage. Once the AC input is accepted, the AC transfer relay
(inside the PRO-Verter) closes and Charger mode begins.
View the top line of the LCD screen and the corresponding message in this section to identify and
understand the particular Charger mode.
Absorb Charging
The Absorb charge state is the constant voltage stage and begins when the absorb voltage is
reached (determined by the SETUP: 03C Battery Type setting) while Bulk charging. During this
stage, the DC charging current decreases in order to maintain the absorb voltage setting. This
charge stage continues until the 03D Absorb Done (Time, Amps, or SOC) or the 03F Max Charge
Time setting is reached.
Bulk Charging
The battery charger is delivering maximum current (determined by the SETUP: 03E Max Charge Rate
setting) to the batteries. The charger remains in Bulk charge until the absorb voltage (determined by
the SETUP: 03C Battery Type setting) or the 03F Max Charge Time setting is reached.
Float Charging
At the end of the absorb charge time, the charger reduces the charge voltage and maintains the
batteries at the float charge voltage setting (programmed at 29.0 VDC, SETUP: 03C Battery Type
setting).
Charger Standby
This indicates the charger has been disabled to prevent further charging, but the AC power (from
utility or generator) to the AC input is still available on the AC output. This display is shown when the
CHARGER ON/OFF button is pressed while the AC power is passing through the inverter/charger.
Note
: Press the CHARGER ON/OFF button to enable charging again. When enabled, the charger
continues in the previous charge mode and the CHG (green) LED comes on.
Charging
Once Charger mode has been enabled, the unit waits and displays “Charging” to determine the
charge routine. If the DC voltage is low (≤ 25.6 VDC), the charger initiates Bulk charging. If the DC
voltage is high (≥ 25.7), the charger skips the Bulk and Absorb charging stages and go directly to the
final charge stage (Float or Silent).
