Faults and Warnings
Unit stops inverting and waits for
user to clear fault.
Moves to AC bypass and waits for
nominal grid conditions to return
for a minimum of five minutes.
Unit shuts down and waits for
nominal AC output voltage level,
or a manual clear from user.
If inverting, the unit shuts down
and waits for the temperature to
return to nominal value. If in any
of the AC-interactive states
(charging, peak load shaving, sell,
gen support), the unit goes into AC
bypass mode until the temperature
returns to the nominal value. If the
unit is not in AC bypass, it shuts
down until the temperature returns
to nominal value. After these faults
clear, the unit returns to its
previous operating state.
If inverting, the unit shuts down
and waits for nominal voltage. If
operating with a qualified AC
source, the unit charges if charging
is enabled, or remains in AC
bypass if charging is disabled.
