Warning:
Sunlight shines on the panel will generate voltage, high voltage in series may
cause danger to life. Therefore, before connecting the DC input line, the solar
panel needs to be blocked by the opaque material and the DC switch should
be 'OFF', otherwise, the high voltage of the inverter may lead to life-
threatening conditions.

5.3 THE CONNECTION OF THE GROUND LINE
Good grounding is good for resisting surge voltage shock and improving EMI performance.Therefore, before connecting
AC, DC and communication cables, you need to ground the cable rstly. For a single system, just ground the PE cable. For
multiple machine systems, all PE cables of the inverter need to be connected to the same grounding copper platoon to
ensure the equipotential connection. The installation of the shell ground wire is shown as picture 5.11.
Warning:
Inverter has built-in leakage current detection circuit, If an external leakage
current protection device is connected, its operating current must be greater
than 300 mA or higher, otherwise inverter may not work properly.

When the inverter is out of the factory, the installaton location of dataloggeris sealed by a sealed plate as shown in
Picture 5.13. When installing the datalogger, remove the sealing plate, replace it with the sealing plate with square hole
in the accessories, and tighten the screws. Insert the datalogger into the interface and x it with a screw.
The conguration of the datalogger needs to be performed after various electrical connections have been completed
and the inverter DC power on. When the inverter is on the DC power, it is determined whether the datalogger is normally
electried (The LED light shines out of the shell).

6.1 START UP THE INVERTER
6.2 INVERTER SHUTDOWN
When start up the three phase string inverter, should fellow below steps：
Must follow below steps while shutting down the inverter:
6. STARTUP AND SHUTDOWN
Before starting the inverter, make sure that the inverter can meet the following conditions, otherwise it may result in re
or damage to the inverter. In this case, we do not undertake any responsibility. At the same time, to optimize the system
conguration, it is recommended that the two inputs be connected to the same number of photovoltaic modules.
a) The maximum open voltage of each set of photovoltaic modules shall not exceed 1000Vdc under any conditions.
b) Each input of the inverter better use the same type of photovoltaic module in series.
c) Total output power of pv shall not exceed the maximum input power of inverter, each photovoltaic modules shall not
exceed the rated power of each channel.
1. First switch on the AC breaker.
2. Turn on the DC switch of the photovoltaic module, and if the panel provides sucient starting voltage and power,
the inverter will start.
3. When the ac voltage and DC voltage are normal, the inverter start-up is readyto begin. The inverter will rst check the
internal parameters and the grid parameters, while the liquid crystal will show that the inverter is self-checking.
4. If the parameter is within acceptable range, the inverter will generate energy. NORMAL indicator light is on.
1. Switch o the AC breaker.
2. Wait for 30 seconds, turn o the DC switch (if any), or simply disconnect the DC input connector. The inverter will close
the LCD and all LED within two minutes.

The inverter has external zero export function. This function is optional. It can collect counter-current power to control
the output power of the inverter, so that the power of inverter and load can be oset, and the excess power will not be
fed back to the grid. If you purchase the inverter with zero export function, an external zero export device ( SUN limiter
or energy meter) will be included in the package which is necessary for the function.The SUN limiter shows as Pic 7.1.
You can see corresponding line mark next to the green interface. The green terminals on the left are the interface
of three-phase AC line (L1, L2, L3) and N Line (N), and the the right are the interface between three sets of current sensor
and one set of control terminals. SUN limiter will collect voltage and current from these interfaces and send control
signals to the inverter.
