Otherwise, it may result in fire or damage to the inverter. In this case, we do not undertake any
responsibility. To optimize the system configuration, it is recommended that the two inputs be connected
to the same number of PV modules.
6.1. Start Up the Inverter
When starting up the single-phase string inverter please follow these steps
:
1. First, switch on the AC breaker.
2. Turn on the PV module's DC switch, and if the panel provides sufficient starting voltage and
power, the inverter will start.
3. When the AC voltage and DC voltage are normal, the start-up is ready to begin. The inverter will
first 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 an acceptable range, the inverter will generate the normal grid. The
NORMAL indicator light is on.
6.2. Inverter Shutdown
You must follow the below steps while shutting down the inverter:
1. Switch off the AC breaker.
2. Wait for 30 seconds, then turn off the DC switch (if any), or simply disconnect the DC input
connector. The inverter will close the LCD and all LEDs within two minutes.
7. LIMITER FUNCTION
The inverter has an integrated export limitation function. This function is used to quickly adjust the
inverter's output according to the power of the user and solar panels and prevent the inverter's output
from being fed to the power grid.
This limiter function is optional. If you buy the inverter with a limiter, a current sensor will be included in
the package, which is necessary for the limiter function.
7.1. Limiter Function Wiring Diagram
If you are reading this, we believe that you have completed the connection according to the requirements
of Chapter 5. If you have been running your inverter at this time, and you want to use the limiter function,
please turn off the AC and DC switch of the inverter, and wait for 5 minutes until the inverter completely
discharge.
Then connect the current sensor to the inverter limiter interface. Ensure they are reliably connected, and
the current sensor should clamp to the incoming line's live wire. In order to make it easier for you to use
the built-in limiter function of the inverter, we have specifically given the wiring diagram, as shown in
Figure 23, the red lines connected to the utility grid said wire (L), the blue line shows the zero line (N),
