Possible Remedy
Disconnect the wires from the inverter's AC input or AC output
terminals, or both. If the problem immediately disappears, it is an
external wiring issue. The inverter's AC HOT IN and AC HOT OUT
must remain isolated from each other.
Test AC HOT IN and AC NEUTRAL IN terminals with an AC
voltmeter. (See page 57.) If low or fluctuating, this is an external
problem.
The inverter is not intended to sell power to a generator. The
selling activity will drive the generator voltage up to the
disconnection point. It will then reconnect to the generator and
try again. Change input modes, or move the generator to an
input with a different mode selected.
Disconnect AC HOT OUT and AC NEUTRAL OUT wires. Turn the
inverter off and then on. If the problem clears, reconnect the AC
output wires. If the problem recurs when reconnected, an
external AC source is connected to the output.
Check HUB10.3 ports and make certain the master inverter is
plugged into port 1.
MATE3 system display only: Check stacking settings in the Inverter
Stacking menu. Only one master is allowed per system.
Test the generator or device to confirm functionality. Test the
AUX terminals with a DVM. If 12 Vdc is present when the menu
indicates the function is On (and the device still does not work),
then there is an external connection problem. If 12 Vdc is not
present with the function On, the AUX circuit may be damaged.
Contact OutBack Technical Support.
AGS programming is located in the MATE3 and cannot function if
the MATE3 is removed.
Gen Alert or another AUX function may try to start or stop the
generator using the wrong criteria. Make sure all other AUX
functions are disabled.
