Operation
6.1.
Preliminary checks
Please carry out the following checks before commissioning the inverter.
1)
The 3000SP inverter must be securely attached to the wall mounting bracket.
2)
The polarity of the battery cables must be correct and the power cables must be connected securely.
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.
6.2.
Procedure for initial set-up
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 at least 200 W. 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.
