Sunway NT 10000 Commissioning the Solar Inverter, Starting-Up and Shutting-Down Solar Inverter

2.4Commissioning the Solar Inverter

Prior to starting up the Solar Inverter, move the housing cover downwards by releasing the lateral fixation on the right lower side of the housing and pulling the four lateral hexagon socket screws tight.

Do not deposit any objects (e. g. this manual) on the housing of the Solar Inverter. The ventilation behind the Solar Inverter must not be obstructed.

If the device is installed outdoors, please double-check that the cable glands, the housing cover, and the protection cap of the SUB-D9 connector (provided this ter- minal is not allocated) are tight.

Starting-Up and Shutting-Down the

Solar Inverter

As soon as the Solar Inverter has been mechanically installed and connected to the power lines, it can be commissioned as follows. Depending on whether or not you are using DC main switches, the start-up and shut-down sequence for the DC and AC side differs.

Note: The Solar Inverter is supplied from the grid. If the PV output is high enough, the Solar Inverter will switch on autom atically. For that purpose, on and off thres- hold values have been determined.

Start-up (with DC main switch)

1.Switch the grid connection on with the external automatic circuit breaker.

2.Switch the PV generator voltage on by closing the DC main switch. If the PV input voltage is sufficient, the Solar Inverter will start and inject solar energy into the electrical grid. The injection is indicated by the power pointer on the display.
