Battery Troubleshooting
WARNING: Hazard to Human Life
In the event of an electrolyte leak, do not come in contact with the electrolyte.
Immediately disconnect the battery and properly dispose of it.
CAUTION: Hazard to Equipment
Do not connect multiple Mojave batteries in series or in parallel. Do not connect them to
other batteries.
Low SOC Recovery
CAUTION: Hazard to Equipment
Failure to follow these instructions can cause permanent battery damage.
The Mojave ESS battery will protect itself from a damaging overdischarge by ceasing to power the
inverter. This occurs in the case of extended operation without a charging source. It is indicated
by a red battery LED indicator. When this occurs, check OPTICS RE for more information.
To recover the system from this state, perform the following steps.
1. Verify a charging source (AC grid, generator, etc.) is available to immediately begin charging the
battery upon connection to the inverter. Failure to immediately charge the battery after resumption
of operation in this state can cause permanent damage to the battery.
2. Press and hold the
On/Off
button for 5 seconds to override the protection mechanism and allow the
inverter to power up.
3. Inverter should energize and charging should begin upon qualification of the source. This charge
may be at a lower power level than usual until the battery returns to the normal operating range.
If the inverter is unable to qualify the AC source and begin charging the battery, then the battery
should be turned off. This will preserve capacity for further troubleshooting. A connected inverter
will continue to drain the battery in this state.
