5.0 Operation
• Full Charge – This status indicates that you have entered the Battery
Saver™ mode. This mode maintains the batteries without overcharging, and
prevents excessive loss of water in fl ooded batteries or drying out of GEL/
AGM batteries. After four hours of Float charging, the charger will turn off
and “Full Charge” displays (charger is now in Battery Saver™ mode). If the
battery voltage drops to ≥12.6 (12-volt models), ≥25.2 (24-volt models)
or ≥50.4 (48-volt models), the charger will automatically initiate another
four hours of Float charging. This cycle helps to ensure the batteries are
maintained and continues as long as AC power is continuously connected to
the AC input. “Full Charge” only displays if Multi-Stage is selected from the
03G Final Charge Stage menu.
• Load Support AAC – The inverter is in the Load Support (Amps AC)
mode because the inverter load is requiring more power than the incoming
AC source can provide on its own. The inverter pulls the additional current—
that is needed for the loads—from the inverter batteries to keep the incoming
AC current from exceeding the SETUP: 03A AC Input Amps setting.
Info: The Load Support AAC feature operates in parallel with the AC
input to support the inverter loads and is only available on MSH Series
inverter/chargers. It is only active when the inverter is enabled (INV
LED is on).
Info: When the inverter is in Inverter Standby mode (charging and
pass-thru), the current is normally a positive value. However, in Load
Support AAC mode, the inverter amps reading is a negative number
to indicate how much current is being provided/removed from the
inverter batteries. The inverter batteries will continue to provide
current to assist the AC input current until the battery reaches 0.5
volts (12-volt systems), 1.0 volts (24-volt systems) , and 2.0 volts
(48-volt systems) above the SETUP: 02B LBCO setting.
• Load Support VDC – The inverter/charger is in the Load Support (Volts
DC) mode because an external DC source (solar, wind, etc.) is providing
more current than needed—which causes the battery voltage to rise. The
inverter/charger reduces the incoming AC current in an effort to keep the
battery voltage from rising above the temperature-compensated SETUP:
03B Battery Type setting.
Info: The Load Support VDC feature operates in parallel with the AC
input to support the inverter loads and is only available on MSH Series
inverter/chargers. This feature is only active in Bulk, Absorb, Float or
EQ Charge modes and when the inverter is enabled (INV LED is on); it
is deactivated if the charger is in Charger Standby.
• Silent – This displays at the end of the Absorption stage if Silent is
selected from the 03G Final Charge Stage menu. In Silent mode, the charger
is not actively charging but does monitor the battery voltage. When the
battery voltage reaches the Set DC Volts to ReBulk setting (from 03G Final
Charge Stage menu) the charger will restart a Bulk and Absorb charge cycle,
and then transition back into Silent mode at the end of the Absorb cycle.
