O n/O f f
button will not
turn battery off
Delays are not
being observed
Press and hold the button for 5 seconds. Wait at least 10
seconds for battery to respond. Do not push the button again in
that time. If the button fails to respond, turn off the circuit breaker.
Inverter does not
recognize Mojave
battery; inverter does not
update UI with
appropriate information
Connection issue
o
Confirm that the BMS cable is securely connected to the
proper port on the inverter. See page 45.
o
Confirm that the BMS cable is securely connected to the
proper port on the battery. See page 60.
Inverter may not be
approved for use
Check that the inverter is approved to support the use of the
Mojave battery.
Battery goes into a fault
state (red LED) and
stops providing power
after 2 hours of idle
operation
Connection issue
o
Confirm that the BMS cable is securely connected to the
proper port on the inverter. See page 45.

Inverter may not be
approved for use
Check that the inverter is approved to support the use of the
Mojave battery.
Battery goes into a fault
state (red LED) and
stops providing power
during operation
Various error states;
if inverter is powered
down, UI will not
respond
Check OPTICS RE for an error log and associated
troubleshooting steps.
Cycle the power. Press and hold the
O n/ Of f
button for 5
seconds. Wait at least 10 seconds for battery to respond. Do not
push the button again in that time. If the button fails to respond,
turn off the circuit breaker, wait a short time, and turn it back on.
Battery goes into a fault
state (red LED) and
stops providing power
during commissioning
Pre-charge test
failure
Check the polarity of the DC connection. Confirm that a short is
not present on the battery cables.
Charging/discharging is
at a lower power than
expected
Configuration
Input and output power limits can be set in the inverter. Check
that these values are set appropriately under the
Grid
tab (page
39) or the
Generator
tab (page 46).
Operating conditions
Charging and discharging power can be limited by thermal
conditions.
Charging and discharging power may be limited near the very
high and low ends of the SoC range.
The inverter does not
stop charging or
discharging at the
desired battery SoC
Configuration
SoC charging and discharging limits can be set in the inverter.
Verify appropriate values are set.
The system does not
correctly calculate the
SoC of Mojave battery
used in series or parallel
with another battery
This is not a
supported use;
it poses a significant
risk of equipment
damage
Immediately disconnect the battery from this system.
