Emergency power supply (EPS) mode
NOTE
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.
In case of a power outage, the energy from the photovoltaic field is used
primarily to power domestic loads and secondly to charge the battery. If
the energy required by the loads is high and the energy from the pho-to-
voltaic field is not enough, the missing part is drawn from the battery. In
the absence of photovoltaic production, the energy required by the loads
will be totally supplied by the battery.
ATTENTION!
In order to preserve the health of the battery, the automatic enabling of the EPS
port occurs only if the state of charge is greater than or equal to 5%. Below this
value the EPS mode is inhibited.
Please note the following instructions for operation in EPS mode:
■
The “EPS” mode is automatically ended if, during the discharge, the battery status
reaches the minimum value of 0%. It is automatically restored if the solar energy from the
panels manages to bring the battery to a state of charge equal to or greater than 5%.
■
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 ES-T system does not guarantee the continuity of power supply to the loads con-
nected to it.
■
The total power of the loads connected to the EPS output must be within the range spec-
ified in the technical data. If the total load is higher, the ES-T 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 essential
loads to the EPS port.
■
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 ES-T 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. It is
therefore recommended to connect only essential loads to the EPS port.
