3)
THE GRID/LOAD cables must be connected securely and correctly to the corresponding terminal
block.
4)
The AC switch must be connected correctly between the inverter’s GRID port and the grid. The
automatic AC switch must be set to OFF.
5)
In the case of connection to the EPS, make sure that the AC power contactor is connected correctly.
6)
For lithium batteries, make sure that the communication cable has been connected correctly.

First start-up of the inverter
1.
Switch off the photovoltaic system and any other energy generation from renewable sources; this
can be done by disconnecting the AC power to the photovoltaic inverter by means of the
disconnecting switch installed on the system. Alternatively, the production inverter can be
disconnected on the DC side via the switch on board the inverter or the one specifically installed in
the system.
2.
Make sure that the utility has a consumption of more than 500 W on each phase. Recommended
loads for this operation are hair dryers (800W < P < 1600W), electric heaters (1000W < P < 2000W)
and ovens (P > 1500W). Other types of loads, such as washing machines or heat pumps, although
characterised by high energy consumption, may take some time to reach this level of absorption
after starting.
