4-3.3 Description of Operation
4-3.3.1 Inverter
The System ON/OFF Switch, located on the front panel, allows the user to turn the system power ON and OFF and to reset the
system after a fault.
The Charger ON/OFF and Inverter ON/OFF buttons, located on the Control/Display Unit enable or disable the Charger or
Inverter Functions. The corresponding light next to Inverter/Charger buttons will be steadily on when the unit is in the Inverter
or Charger mode. These Inverter and Charger lights will blink if the mode is not currently on, but are enabled.
For Example: The Inverter light will blink when the Inverter is Enabled, the ITC is plugged into the utility, and the Charger
is Active.
The Inverter AC Output Circuit Breaker is a 1 pole, 30-amp breaker marked “CB-2” on the front unit. The CB-2 breaker
protects the Inverter AC output and a second Breaker (CB-1) protects the Battery Charger AC input against a severe overload.
This CB-1 breaker also protects AC Pass through Power. If this CB-1 breaker trips during charger operation, it must be reset.
4-3.3.2 Inverter Protective Interlocks
The Inverter operation is protected by a series of safety interlocks that protect against most failures such as overloads, over-
temperature conditions or other conditions where the unit may be asked to operate outside safe battery voltages. These
situations will trigger a display of the “Overload”, “Low Battery” and “Fault” indicators on the Control/Display panel and are
listed below:
Overload Inverter AC output current is at the Maximum Current allowed and is presently in “Surge”. The AC
voltage will decrease if load increases. Overload Shutdown will occur if voltage goes below 105 VAC
for 3 seconds.
Dead Battery The inverter continually monitors battery voltage. If battery voltage falls below the Low Battery
Shutdown 10.5 (21.0) VDC setpoint the inverter will shut OFF. Auto-reset will restart the inverter
after battery voltage rises above the Low Battery Warning 11.0 (22.0) VDC setpoint (after
5 minutes).
High Battery The inverter will shut OFF if battery voltage rises above the High Battery 16.0 (31.0) VDC setpoint.
Battery Low Warning Battery voltage is below Low Battery Warning setpoint and soon may reach Low Battery Shutdown
setpoint of 11.0 (22.0) VDC.
Over Temperature The inverter will shut OFF if internal temperature sensors detect a high temperature condition that
could damage the inverter.
Hardware Fault Internal protection circuit activated or power brick high temperature will shut down system.
If the unit has faulted there are the two following options:
1. Auto-restart After shutting down for any of the above fault conditions, the inverter will try to restart itself every
5 minutes if Auto-Restart is Enabled and the fault condition no longer exists.
2. Manual restart You can manually restart the system after the fault conditions are removed. Reset the inverter by
turning the System ON/OFF Switch OFF and then ON.
