2. If a system display is present, perform all programming for all functions.
These functions may include AC input modes, AC output voltage, input current limits, battery
charging, generator starting, and others.
3. Turn on the inverter using the system display (or external switch, if one has been installed).
The inverter’s default condition is Off. Do not turn on any AC circuit breakers at this time.
4. Using a DVM or voltmeter, verify 230 Vac (or appropriate voltage) between the AC HOT OUT
and AC NEUTRAL OUT terminals. (See Figure 28 for AC terminals.) The inverter is working
correctly if the AC output reads within 10% of 230 Vac or the programmed output voltage.
Proceed past the items below to Step 5 on the next page.
To start a multiple-inverter (stacked) system:
1. Close the main DC circuit breakers (or connect the fuses) from the battery bank to the inverter.
Repeat for every inverter present. Confirm that the system display is operational.
With the system display, perform any programming for stacking and all other functions.
These functions may also include AC input modes, AC output voltage, input current limits,
battery charging, generator starting, and others. When stacking in parallel, all slave inverters
will observe the programming settings for the master. They do not need to be programmed
individually. The MATE3 Configuration Wizard may be used to assist programming.
2. Turn on the master inverter using the system display (or external switch, if one is installed).
The inverter’s default condition is Off. Do not turn on any AC circuit breakers at this time.
3. Using the system display, temporarily bring each slave out of Silent mode by raising the Power
Save Level of the master.

As each slave is activated, it will click and create an audible hum.

Confirm that the system display shows no fault messages.
