Figure 3 AC Terminals
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.
AC input modes are described beginning on page 17 and are summarized on page 25. The
inverter’s individual operations are described beginning on page 27.
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 120 Vac (or appropriate voltage) between the AC HOT OUT
and AC NEUTRAL OUT terminals. (See Figure 3 for AC terminals.) The inverter is working
correctly if the AC output reads within 10% of 120 Vac or the programmed output voltage.
5. Proceed past the items below to Step 6 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 master programming settings. They do not need to be programmed individually.
The MATE3 Configuration Wizard may be used to assist programming.
AC input modes are described beginning on page 17 and are summarized on page 25. The
inverter’s individual operations are described beginning on page 27. Stacking is described
beginning on page 43.
2. Turn on the master inverter using the system display (or external switch, if one has been
installed). The inverter’s default state is Off. Do not turn on any AC circuit breakers at this time.
