4.4 System Start-up and Testing
Step 1: Completely install the ITC-Series Inverter/Charger following the system design considerations and
instructions provided previously in this manual.
Step 2: Place the System Power On/Off switch located on the front of the inverter in the OFF position.
Step 3: Verify that the external GFCI breaker is reset and connect an AC load, such as a 100-Watt light.
Step 4: Turn ON the battery DC power to the inverter.
Step 5: Turn ON the AC shore power (or generator) to supply the AC input power to the system
Step 6: Place the System On/Off Power switch located on the front of the inverter to the ON position.
Step 7: The Lights on the Control/Display Unit on the front of the inverter should come ON, by doing a lamp
test.
Step 8: Disable the Charger Operation of the unit by pressing the Charger ON/OFF button once if the Charger
LIGHT is On or blinking. This turns the charger function OFF.
Step 9 If the Inverter LIGHT is not On or blinking, enable the Inverter Operation of the unit by pressing the
Inverter ON/OFF button once. This turns the Inverter function ON.
Step 10 The AC output test light should come ON, indicating the presence of shore power and correct
operation of the AC transfer switch.
Step 11: Turn off the AC shore power input. The AC output test light should immediately quickly blink once,
indicating the transfer switch transferred the test light from shore power to inverter power.
Step 12: At this point, apply AC loads up to rated output watts to verify full-power operation.
Step 13: Apply shore power. After a delay the AC output test light should blink and the ITC Inverter LIGHT
should blink indicating the transfer of the load from inverter power to shore power.
Step 14: Test the battery charger operation
A) With shore power applied, press the Charger ON/OFF button to enable the Charger (if not enabled). The
Charge LIGHT should come on and the batteries should begin charging. Remember to reduce the loads
on the unit since the APM will limit the available power to the charger based on its settings.
B) Disconnect the shore power – the unit should transfer back to Inverter mode.
C) Discharge the battery by placing the AC load on the system and operating the inverter.
D) When the battery charge level is low, the inverter will turn off.
E) Connect an ammeter to the DC cables between the inverter and the battery to monitor the current (DC
amps), and a voltmeter to the battery to monitor the battery voltage. The battery charger will step through
its sequence and stop in the float mode.
Step 15: The system is now ready for operation.
5 GENERAL INFORMATION SECTION
5.1 Generic Inverter Description
In general, an inverter converts DC electrical power into AC power. This power can be used to operate various
AC-driven appliances. Typical DC power sources include batteries that store electrical energy, power generated
from a vehicle alternator or renewable energy sources such as photovoltaic (solar) panels both with the
appropriate regulator or charge controller to bring the DC source within the operating range of the inverter.
The most common battery systems are 12 or 24 volt. Some systems, however, operate on higher voltages such
