5. Using the system display, temporarily bring each slave out of Silent mode by raising the Power
Save Level of the master. (See page 39.)
 As each slave is activated, it will click and create an audible hum.
 Confirm that the system display shows no fault messages. Confirm that the output voltages are still
correct. Individual slave voltage readings are not necessary since all slave inverters are in parallel.
 When this test is finished, return the master to its previous settings .
After output testing is completed, perform the following steps:
6. Close the AC output circuit breakers. If AC bypass switches are present, place them in the normal
(non-bypass) position. Do not connect an AC input source or close any AC input circuits.
7. Use a DVM to verify correct voltage at the AC load panel.
8. Connect a small AC load and test for proper functionality.
9. Close the AC input circuit breakers and connect an AC source.
 Using a DVM on the correct input, check the “L” and “N” input terminals for 230 Vac (or appropriate
voltage from the AC source.)
 If a system display is present, confirm that the inverter accepts the AC source as appropriate for its
programming. (Some modes or functions may restrict connection with the source. If one of these
modes has been selected for the system, it may not connect.) Check the system display indicators for
correct performance.
NOTE: If any Phase B or Phase C inverters are wired to the wrong AC source phases, the inverters
will not connect to the AC source and will display a Phase Loss warning. See page 58.
10. If the charger is activated, the inverter will perform a battery charging cycle after powering up.
This can take several hours. If restarted after a temporary shutdown, the inverter may skip most or
all of the charging cycle. Confirm that it is charging as appropriate by using the system display.
11. Test other functions which have been enabled, such as generator start, selling, or search mode.
12. Compare the DVM’s readings with the system display meter readings. If necessary, the system
display’s readings can be calibrated to match the DVM more accurately. Calibrated settings
include AC input voltage for the
Grid and Gen inputs, AC output voltage, and battery voltage.
Powering Down
If steps are inapplicable, they can be omitted. However, it is highly recommended that all applicable
steps be performed in the following order. These steps will completely isolate the inverter.
To remove power from the system:
1. Turn off all load circuits and AC input sources.
2. Turn off all renewable energy circuits.
3. Turn each inverter OFF using the MATE3 system display or external switch.
4. Turn off the main DC overcurrent devices for each inverter.
Adding New Devices
When adding new devices to the system, first turn off the system according to the preceding
instructions. After adding new devices, perform another functional test, including programming.
