Table 4 Basic Troubleshooting Steps
Possible Cause
No AC input.
Charger set to OFF.
Charge complete or nearly
complete.
System display's DC meter reads
significantly higher than actual
battery voltage.
Generator type does not work well
in conjunction with Grid/Generator
Support feature (see page 16).
High output loads. If total loads and
charge exceed input setting, charge
will decrease to give priority to
loads.
Inverter priority
AC source does not meet
requirements.
High output loads will consume
power before it is returned to the
utility grid.
Inverter has been set to accept a
generator.
Troubleshooting
Possible Remedy
See "Will not connect to AC" category
below.
MATE system display only: Check
Charger Control screen with AC IN hot
key and set to ON or AUTO. (If this
setting was intentional, then no action is
required.)
Check the DC voltage and charging
stage using the system display, if
present. Confirm with DC voltmeter.
Check the DC voltage on the inverter's
DC terminals. If different from the
system display reading, the inverter
could be damaged. Otherwise, check
the DC voltage on batteries with a
voltmeter. If different from the reading
on the inverter, this could be a DC
connection problem.
MATE system display only: Turn off the
ac2/gen support feature in
ADV/FX/GEN menu. The ac transfer
control must be set to gen in order to
do this. In current models, if ac transfer
control is set to grid, the support
feature cannot be disabled.
Turn off some of the output loads and
test the charge rate again.
MATE system display only: Check Stop
Sell Reasons menu (STATUS/FX/SELL).
Inverter may be behaving correctly.
Verify grid voltage and frequency.
Determine if they are within the
inverter's approved limits. If not the,
inverter is behaving correctly. Contact
the utility company if necessary.
MATE system display only: The program
selections for limits are IEEE or USER.
Turn off some output loads and observe
the sell function.
Inverter will not intentionally sell to a
generator.
MATE system display only: Set ac transfer
control to grid.
