4. General description
4.1 xStorage Home 3P high voltage hybrid inverter
The xStorage Home 3P High Voltage (HV) hybrid inverter (see Figure 1) is a DC - AC solar inverter, designed for use in indoor
environments. It has been designed to be used in combination with PV panels and connected to the electricity grid and a high
voltage (HV) storage battery to optimize self-consumption. In the event of a temporary or permanent power outage, the xStorage
Home 3P automatically enables the off-grid operation on the EPS port supplying, with the backup energy, the part of the home
system connected to it.
All adjustment and control operations can be performed on the LCD (touch screen) located on the front of the xStorage Home 3P.
4.2 Operating modes
The xStorage Home 3P HV hybrid inverter can operate in different operating modes in order to meet the specific needs of
the user. Please consider that only the Eaton certified installer can change the operating modes depending from user needs.
4.2.1 “SELF-CONSUMPTION” mode
In the presence of sunshine, the energy from the photovoltaic field is used primarily to supply the domestic loads and secondly to
charge the battery. Further energy in excess is transferred to the grid. If the energy required by the loads is high and the available
energy from photovoltaic field and battery is not enough, the remaining part is taken from the grid.
This operating mode is mainly indicated in installations with a low tariff for the energy fed into the grid and a high cost
for the energy purchased from the utility.
Figure 4. Eaton xStorage Home 3P self-consumption mode during the day
xStorage
In the absence of energy from the photovoltaic system, the battery is discharged to supply domestic loads. If the energy required
by the loads is higher than the energy stored the battery, the remaining part is taken from the grid. The energy stored in the battery
usually does not feed in to the grid and it is used to supply the home loads.
Figure 5. Eaton xStorage Home 3P self-consumption mode during the night
xStorage

14 XSTORAGE HOME 3P ENERGY STORAGE SYSTEM USER MANUAL MN700011EN May 2023 www.eaton.com
4.2.2 “FEED-IN CONTROL” mode
This operating mode is mainly indicated in installations where local regulations require a limitation on the energy that
is injected in to the grid.
1
xStorage
Figure 6. Eaton xStorage Home 3P feed in control mode during the day
In the presence of sunshine, the energy from the photovoltaic system is used primarily to supply the domestic loads and
secondly to charge the battery. Further energy in excess is transferred to the grid with the possibility to set a limit on the value
of the maximum power fed into the grid. If the set limit is zero and there is no demand for energy from the loads, the inverter
will limit the input power to the set value by reducing the production of the photovoltaic energy until it completely inhibits it.
Therefore, by setting the input limit to 0 W, the system will totally prevent the transfer of energy to the grid. Moreover, if the
energy required by the loads is high and the available energy from photovoltaic field and battery is not enough, the remaining part
is taken from the grid.

In the absence of energy from the photovoltaic field, the battery is discharged to supply domestic loads. If the energy required
by the loads is high and the energy in the battery is not enough, the remaining part is taken from the grid. The energy stored in
the battery usually does not feed in to the grid and it is used to supply the home loads.

Figure 8. Eaton xStorage Home 3P battery manager mode during the day
xStorage
In the presence of sunshine, the energy from the photovoltaic system is used primarily to supply the domestic loads and
secondly to charge the battery starting from the set charge start time. This allows you to start charging the battery at the most
convenient time of the day.
4.2.3 “BATTERY MANAGER” mode
This operating mode is mainly indicated in installations where it is convenient to enable the battery charge during the
high photovoltaic production time over the day and to operate a delayed discharge of the battery when the home energy
demand is high or when the cost of energy is expensive.
Figure 9. Eaton xStorage Home 3P battery manager mode during the night
xStorage
In the absence of energy from the photovoltaic field, the battery is discharged to supply the domestic loads only starting from the
set time in order to keep the energy reserve ready for the evening moments of maximum demand and minimize any consumption
from the grid in case of absorption peaks. It is also possible to set a usage time limit to disable the battery use and keep an
energy reserve for the morning after to support the energy demand from the loads when the photovoltaic production is not
present yet.

16 XSTORAGE HOME 3P ENERGY STORAGE SYSTEM USER MANUAL MN700011EN May 2023 www.eaton.com
Figure 10. Eaton xStorage Home 3P Emergency power supply (EPS) mode
xStorage
In case of a power outage, the energy from the photovoltaic system is used primarily to supply domestic loads and secondly to
charge the battery. If the photovoltaic system is not able to supply the loads then the remaining part is taken from the battery. In
the absence of photovoltaic production, the energy required to supply the house loads will be totally taken from the battery.
4.2.4 “EMERGENCY POWER SUPPLY (EPS)” mode
In case of a power outage, this operating mode allows an emergency output (EPS) to be activated to supply the
privileged domestic loads. In order to activate this operating mode, the presence of the battery is required.
WARNING:
In order to preserve the health of the battery, the automatic enabling of the EPS port occurs only if the state of
charge is higher or equal to 5 %. Below this value the EPS mode is inhibited.
WARNING:
The “EPS” mode automatically ends during the discharge in case the battery status reaches the minimum value of 0
%. The mode is automatically restored if the solar energy from the panels manages to bring the battery to a state of
charge equal or higher than 5 %.
WARNING:
The total power of the loads connected to the EPS output must be within the range specified in the technical
data. 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. 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 the overload event will be flagged. 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 datasheet. It is therefore recommended to connect only critical
loads to the EPS port.
WARNING:
The activation of the EPS port in case of a power outage can take a predetermined time which depends on the
regulations in force in the country of installation. For this reason, the xStorage Home 3P system cannot be
used as a UPS as it does not guarantee the continuity of power supply of the loads connected to it.

17 XSTORAGE HOME 3P ENERGY STORAGE SYSTEM USER MANUAL MN700011EN May 2023 www.eaton.com
This operating mode allows you to maintain a reserve of energy stored in the battery always ready to be used in the
event of a power outage and is particularly suitable for installations in areas where power outages often occur.
4.2.5 “BACKUP RESERVE” mode
Figure 11. Eaton xStorage Home 3P back up reserve mode
xStorage
In this operating mode the battery is forced to be charged up to a pre-set minimum level and usually does not discharged below
that level during normal self-consumption operation. The reserve of the battery state of charge is maintained by the energy
produced by the photovoltaic field or it might be taken from the grid. In order to guarantee the pre-established backup level, the
energy stored in the battery is usually not fed in to the grid, but it is reserved exclusively to supply the loads.
4.3 HV Lithium-ion battery
The xStorage Home 3P HV hybrid inverter can be connected to a high voltage lithium-ion storage battery (HV) to store the energy
from the PV panels and to optimize self-consumption.
The xStorage Home 3P hybrid inverter can operate with various high voltage (HV) batteries which have been specifically tested
and approved by Eaton to ensure the safety and optimal operation of the system.
WARNING:
Connect only the battery models approved by Eaton to the xStorage Home 3P hybrid inverter. Contact your Eaton
sales representative to get further details.
The calibration charge is primarily carried out by the energy coming from the solar panels which is entirely destined for
this purpose. If the energy available from the solar panels is not enough then the remaining part is taken from the grid.
Based on the state of health of the battery and to get an accurate and reliable state of charge (SoC) indication, the control module
integrated in the battery (BMS) cyclically requests the xStorage Home 3P hybrid inverter to carry out a calibration and to charge up to
100 %. This allows to make the best use of the battery, maximize the useful life of the internal cells and to optimize battery performances.
4.3.1 Calibration charge
WARNING:
During the calibration charge, normal system functionalities are disabled, and the battery cannot be used by the system.
All system functionalities are automatically restored at the end of the calibration process.

18 XSTORAGE HOME 3P ENERGY STORAGE SYSTEM USER MANUAL MN700011EN May 2023 www.eaton.com
WARNING:
The maintenance charge is a safety function of the battery to avoid damages. For this reason, the xStorage Home 3P hybrid inverter
can activate grid charging if the available photovoltaic energy is not enough.
WARNING:
During the maintenance charge, normal system functionalities are disabled, and the battery cannot be used by the system.
All system functionalities are automatically restored at the end of the maintenance process.
WARNING:
During the maintenance charge the EPS mode is disabled. It is automatically restored at the end of the maintenance process.
WARNING:
Maintenance charge is required by the battery integrated control module (BMS). The xStorage Home 3P hybrid inverter cannot in
any case disable the command from the battery.
The maintenance charge brings the state of charge from the minimum value to a value determined by the BMS based
on the state of health of the cells. The charging current is also determined by the BMS module based on the health and
temperature of the battery itself.
The duration of the maintenance charge depends on the energy available from the solar panels and on the health of the cells of
the battery. This process can take a long time (hours) especially during the winter when the available solar energy can be very low.
During the winter period or after long periods of inactivity, the battery may remain at the minimum state of charge for a long time
with the risk of a deep discharge phenomena with consequent risk of structural damage to the internal cells. Therefore, to avoid
damages of the battery, the control module integrated in the battery (BMS) may require the xStorage Home 3P hybrid inverter to
carry out a maintenance charge.

WARNING:
During the calibration charge the EPS mode is disabled. It is automatically restored at the end of the calibration process.
WARNING:
Calibration charge is required by the battery integrated control module (BMS). The xStorage Home 3P hybrid inverter cannot in any
case disable the command from the battery.
The duration of the calibration charge depends on the energy available from the solar panels and on the health of the cells of the battery.
This process can take a long time (hours and / or days) especially during the winter when the available solar energy can be very low.
The calibration charge status is shown on the display status bar.

See the connection instructions shown in Figure 2.
Insert the Wi-Fi dongle supplied with the inverter accessories in the USB port and wait for the system to recognize
the device (transparent Wi-Fi icon).
To set the correct operation of the connection it is necessary to access the configuration menu “SETTINGS” and set
the networking parameters of the “WLAN” menu according to the characteristics of the local network to be accessed.
Please refer to the xStorage Home 3P user interface display manual, “NETWORKING” section.
To ensure optimal Wi-Fi connectivity, make sure that the Wi-Fi signal available near the installation of the xStorage Home
3P system is high enough to allow a stable connection. For this purpose, during the configuration of the network parameters,
the scanning and selection of the Wi-Fi network carried out by the xStorage Home 3P reports the signal strength of the wireless
network to which you intend to connect: select a network with signal strength S > - 60 dBm. If the detected signal is weak
(S < -60 dBm), the connection is not guaranteed and therefore it is necessary to provide for the use a Wi-Fi repeater.
If the configuration operations are carried out correctly, the effective connection to the local Wi-Fi network is shown by the
Wi-Fi icon (icon highlighted) on the status bar of the display and by the stable lighting of the blue LED on the control panel.
WARNING:
Use only the Wi-Fi dongle supplied with the inverter accessory. The correct functioning of Wi-Fi connectivity is not
guaranteed with not approved similar devices.
