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
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.
