00 Title
Before carrying out any operations, make sure to have read and understood this manual. Do not make
changes and do not carry out maintenance operations not described in this manual. The manufacturer does
not accept responsibility for injuries to people and damages to things occurred because the information
within this manual has not been read and followed.
The installation must only be carried out only by Eaton certified personnel.
The operations described here must be carried out only by Eaton certified installers.
The customer is civilly liable for the qualification and mental or physical state of the professional figures who
operate this equipment. They must always use the personal protective equipment required by the laws of
the country of destination and anything else provided to their employer.
The xStorage Home 3P system can also operate without the connection to the grid (off-grid). Under these
conditions and based on the system settings, the hybrid inverter output can be automatically switched to
the EPS port which, by means of an external interlock system, will feed the loads connected to a privileged
line. According to the safety provisions in force in the country of installation, the NEUTRAL line may have
to be connected to the earth potential to guarantee the operation of the protection systems against direct
discharge provided for the privileged line and located downstream of the hybrid inverter and / or to ensure
the correct operation of the loads connected to the EPS port. If, due to particular needs, this connection
should not be made, the hybrid inverter output remains floating.
Emergency power to the EPS port is automatically turned on and off based on PV panels irradiation
conditions and battery charge status. This means that during an emergency the power supply of the EPS
port can be unexpectedly restored even in standby mode. For this reason, in order to avoid possible injuries
from electric shock, before carrying out any installation or maintenance work on the home network, it is
necessary to deactivate the xStorage Home 3P operation using the ON/OFF switch and disconnect it both
from the AC power supply, by opening the main circuit breaker, and from the photovoltaic field, by opening
the DC disconnector integrated in the xStorage Home 3P.
PV panels, when exposed to the sun, can produce dangerous voltages. It is recommended to carry out all
the procedures necessary to make the work area safe.
The xStorage Home 3P system operates with high voltage lithium-ion batteries (HV). Batteries produce
electricity and can cause electric shock or fire in the event of a short circuit or incorrect installation.
Only high voltage (HV) lithium-ion batteries approved by Eaton can be connected to the xStorage Home 3P
system. The use of non-approved batteries can affect the correct functioning of the system and relieves
Eaton from all liabilities and invalidates the guarantee.
Batteries must be installed in a suitable area that complies with local regulations. The installation area must
ensure enough ventilation and the absence of open flames and sparks as potentially explosive gases may be
generated during operation.
It is strictly prohibited to open the xStorage Home 3P system except as listed in this manual. The installation
of the equipment must not be carried out by personnel who are not certified by Eaton under the influence of
alcohol or drugs, or with prosthetic heart valves or pacemakers.
These instructions are intended for Eaton certified installers.
