Title
WARNING: The total power of the loads connected to the EPS output must be within the range
specified in the technical data specifications.
If the total load is higher, the xStorage Home 3P will enter
in protection mode, disabling the output power and signaling the overload event. After a few seconds it
will attempt to restore the regular operation of the EPS port. This restart mode will continue until the total
load connected to the EPS port is compatible with the maximum ratings specified in the technical data. It is
therefore recommended to connect only critical loads to the EPS port.
WARNING: In EPS mode, some loads may not work properly even if their total rated power is
within the limits specified in the technical data specifications.
This can happen because the inrush
currents could be too high (refrigerators, air conditioners, hydraulic pumps, etc.). In these cases, the
xStorage Home 3P hybrid inverter will enter in protection mode, disabling the output power and signaling
the overload event. After a few seconds it will attempt to restore the regular operation of the EPS port. This
restart mode will continue until the total load connected to the EPS port is compatible with the maximum
ratings specified in the technical data specifications. It is therefore recommended to connect only critical
loads to the EPS port.
Before connecting the battery to the xStorage Home 3P system, make sure to have read and understood
all the instructions provided in the operating and installation manual supplied by the battery manufacturer.
Failure to follow the instructions provided in this manual may affect the correct operation of the system, lead
to potentially hazardous situations, relieves Eaton from any liability and invalidates the guarantee conditions.
The xStorage Home 3P system can operate with high voltage (HV) lithium-ion batteries. Batteries produce
electricity and can cause electric shock or fire in the event of a short circuit or incorrect installation.
WARNING:
Local regulations in force in the country of installation may require the installation of an external
DC circuit breaker in addition to the automatic disconnector integrated in the xStorage Home 3P. The DC
circuit breakers must be properly rated for the + and - lines in order to guarantee the safe disconnection of
the battery from the inverter in case of maintenance.
The xStorage Home 3P is fitted with a safety fuse against battery short-circuits. The fuse is
30 A 1000 Vdc
gPV rated.
In the event of replacement, the fuse ratings must not be exceeded in any way as this could
cause electric shock or fire in the event of a short circuit.
Before starting the connection operations, make sure that the battery cables are disconnected from the
battery and that the poles are insulated to prevent short circuits.
Before starting the connection operations, make sure that the AC GRID and EPS circuit breakers are
disconnected.
Contact Eaton sales representative to identify the supported batteries.
WARNING: The default factory setting of the xStorage Home 3P is set to operate without any
battery connected to the system.
To enable HV battery operation, access the “SETTINGS” configuration
menu in INSTALLER mode, access the “BATTERY” menu and select the correct HV battery model from
those listed in the “LITHIUM” menu. Please refer to the xStorage Home 3P user interface display manual.
Moreover, INSTALLER mode is reserved only for Eaton certified installers.
