Adding and Replacing the Batteries
Prior to uninstalling a battery(ies), Customer Service must ensure that
the state of charge (SoC) matches the SoC as given in Replacement
Battery Information sheet in the box with the Replacement Battery(ies).
This is accomplished by charging or discharging the battery until SoC on
Dashboard matches the SoC on the Replacement Battery Information
sheet.
The battery will continue to operate until it reaches the desired SoC.
Since the rate at which the battery can charge or discharge is governed
by the loads, it can take several hours for the desired SoC to be reached
and for the Battery to be ready for replacement. Customer service will set
the system to the backup power program at the desired SoC 24-48 hours
in advance of the physical removal of the Battery. This is to ensure that
sufficient time has passed to allow the Battery(ies) to be at the correct
SoC when customer service personnel arrives to replace the battery(ies).
• Once the Battery(ies) SoC is confirmed to be at the same SoC as the
Replacement Battery(ies).
• Verify that all power is removed from the system before attempting
to remove the Battery(ies) by Initiate Rapid Shutdown and allow the
DC voltage to drop to a safe level power down Inverter and disconnect
wiring sources of AC and DC power .
