A battery can present a risk of electrical shock and high short-circuit current. The following
precautions should be observed when working on batteries.
a) Remove watches, ring, or other metal objects.
b) Use tools with insulated handles.
c) Wear rubber gloves, boots and glasses
d) Do not lay tools or metal parts on top of battery.
y
Do not leave the ESS in the Fault standby state for a long time because of the battery discharge
may occur during the long standby state.
y
If the battery fault occurs immediately after starting PCS it means Battery failure. Check the
battery SOC also voltage and fault information, and turn off the power of the ESS until service
action is taken.
y
If the battery SOC is low the battery may charge from the grid for self-protection. (Emergency
Charging) This function is to prevent shutdown of the ESS, deep discharge and failure of the
Battery. An Emergency Charge is not an ESS fault.
