Symptom Possible Cause
Charge complete or nearly
complete.
MATE3's DC meter reads
significantly higher than actual
battery voltage.
Low charge rate.
High output loads.
High temperature.
No AC input.
Charger set to Off.
Will not charge.
GridZero mode in use.
Grid-tied function has been
manually disabled.
Grid Tied mode not in use.

mode.
The inverter has other criteria
besides the AC source which
must be met, such as the
qualifying time.
The inverter will perform the
Offset function before
attempting to sell.
AC source voltage is driven high
when the inverter sells large
amounts of power.
Reduced power sold
to the utility grid.
High temperature.

Possible Remedy
Check the DC voltage and charging stage using the MATE3, if
present. Confirm with DC voltmeter.
Check the DC voltage on the inverter's DC terminals. If different
from the MATE3 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.
If total loads and charge exceed the AC input setting, charge rate
decreases to give priority to the loads. Turn off some of the
output loads and test the charge rate again.
The inverter will reduce the current rate for charging and other
activities if the internal temperature exceeds a certain level.
Check temperature readings and allow the inverter to cool if
necessary. (See page 64.) External cooling may also be applied.
See "Will not connect to AC" category.
MATE3 system display only: Check the Charger Mode screen with
the CHARGER hot key and set to On or Auto. (If this setting was
intentional, then no action is required.)
MATE3 system display only: The charger is inoperative in GridZero
mode. (If this setting was intentional, then no action is required.)
MATE3 system display only: Check the Grid-Tie Enable setting in
the Grid-Tie Sell menu. Confirm it is set to Y.
MATE3 system display only: Check the Inverter part of the Settings
menu to see if Grid Tied mode is in use.
Verify grid voltage and frequency. Determine if they are within
the inverter's approved limits. If not, the inverter is operating
correctly. Contact the utility company if necessary.
MATE3 system display only: The program limits are found in the
inverter's Grid Interface Protection menu. See page 20 for more
information on this menu.
MATE3 system display only: Check Sell Status screen using the
Home screen's soft keys. The inverter may be operating correctly.
Depending on the conditions which need to be met, the delay
may be temporary.
Output loads can consume all excess renewable power if they are
large enough. (The Offset function "sells to the loads.") Turn off
some output loads and observe the sell operation.
When the inverter senses a rise in grid voltage while selling, it
reduces the sell current, to avoid forcing the voltage to
unacceptable levels. Check AC input voltage while selling. The
inverter may be operating correctly.
The inverter will reduce the current rate for selling and other
activities if the internal temperature exceeds a certain level.
Check temperature readings and allow the inverter to cool if
necessary. (See page 64.) External cooling may also be applied.
