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 DC circuit breaker must be correctly connected between the battery and the 3000SP inverter,
and must be set to OFF (only if it has been installed, e.g. for lead-acid batteries).
4)
THE GRID/LOAD cables must be connected securely and correctly to the corresponding terminal
block.
5)
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.
6)
In the case of connection to the EPS, make sure that the AC power contactor is connected correctly.
7)
For lithium batteries, make sure that the communication cable has been connected correctly.
8)
For lead-acid batteries, make sure that the NTC cable (temperature probe) has been connected
correctly.
6.2.
Procedure for initial set-up
Important:
carefully follow the procedure below to start up the 3000SP inverter.
1)
Make sure that no power is generated by the photovoltaic system on the phase where the 3000SP
inverter is connected (open the DC circuit breaker between the inverter and the modules and/or AC
circuit breaker between the inverter and grid).
2)
Switch on the batteries:
In the case of Pylontech batteries, turn ON the switch located on the front of all the batteries and
make sure that the green LED underneath lights up; then hold down the red SW button of only one
battery for one second. The LEDs of all the connected batteries will light up and then go out, while
the green RUN LED will stay on with a steady or flashing light.

In the case of Tawaki Maui batteries, press the POWER button to set it to the ON position, making
sure that the L8 (Mod. RACK 17002) or L1 (Mod. MAUI 17012) indicating light is on; if the L8 or L1
light is off, immediately switch off the battery pack.
