WIRING CHECK
Before powering on the GTI, recheck all wiring and ensure it is connected to
the proper terminals. Check that the ground and neutral connections are
properly wired and tight.
After all the wiring has been checked, install the front cover and secure it
with the four phillips screws removed in the beginning of the installation.
OPERATING STACKED INVERTERS
Stacked inverters must operate together in order to provide the 120/240 Vac
to the loads. The Series Stacking Interface cable ensures the output from each
inverter is 180 degrees out-of-phase for operating 240 Vac loads.
NOTE: Until the units are tested, do not connect loads
to the inverters 120 or 240 Vac output.
START-UP AND TEST
1. Ensure the main service panel’s circuit breakers feeding the inverters are
OFF.
2. Switch ON both inverters. The inverter should be providing 120/240 Vac
to the sub-panel.
3. Use an AC voltmeter and measure the voltage between the L1 terminal and
neutral bus in the sub-panel. This voltage should be 120 Vac (± 3%).
4. Measure the voltage between the L2 terminal and neutral bus in the sub-
panel. This voltage should be 120 Vac (± 3%).
5. Measure the voltage between the L1 and L2 terminals in the sub-panel.
This voltage should be 240 Vac (± 3%).
6. Switch ON the main service panel’s circuit breakers feeding the inverters.
7. Verify the inverters are charging the batteries and powering the sub-panel
(refer to the operator’s manual).
8. Switch both inverters OFF.
9. Replace all covers and panels on the inverters and sub-panel.
The stacked inverter system is now ready for use.
NOTE: If the inverters are not operating properly, please
refer to the operator’s manual for setup and
troubleshooting information.
