In the event of a power failure, or operation in OFF-Grid mode, if the EPS function is enabled, the HYD-ES inverter
will operate in Emergency Power Supply (EPS) mode using the PV power and energy stored in the battery to
supply power to the critical load via the LOAD connection port.
•
High power loads (such as ovens, washing machines, heat pumps) may not be supported by
the inverter in EPS mode, given the maximum power that can be delivered under these
conditions.
•
Loads with high inrush currents (such as pumps, compressors or in general devices driven by
electric motors) may not be supported by the inverter in EPS mode, as the inrush current, even
if only for a very short period, is considerably higher than that supplied by the inverter.
•
Inductive loads (such as induction plates) may not be supported by the inverter in EPS mode,
due to the waveform of these devices.
Identify critical or priority domestic loads
: it is advisable to identify the domestic loads strictly necessary during
power outages, such as lights, refrigerators or freezers, emergency sockets.
Connect the phase, neutral and ground wires to the LOAD output
located on the right side of the bottom of
the inverter.
NOTE: the LOAD output must only be used for connecting the critical load.

The “Anti Reflux Control” mode can be enabled to limit
the maximum power exported to the grid. The set reflux
power corresponds to the desired maximum export
power to the grid.
