5.0 Operation
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: 02 LowBattCutOut setting.

Figure 5-15, Load Support VDC Mode

• 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: 04
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.

Figure 5-16, Silent Mode

• Silent – This displays at the end of the Absorption stage if Silent is
selected from the 09 Final Charge menu. In Silent mode, the charger is not
actively charging but does monitor the battery voltage. When the battery
voltage reaches the ReBulk setting (from SETUP: 09 Final Charge 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.
