Figure 10. Eaton xStorage Home 3P Emergency power supply (EPS) mode
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.
