6. Startup and Shutdown
6.1 Start up the inverter
6.2 Inverter Shutdown
Before star�ng the inverter, make sure that the inverter can meet the following condi�ons,
otherwise it may result in fire or damage to the inverter. In this case, we do not undertake any
responsibility. To op�mize the system configura�on, it is recommended that the two inputs be
connected to the same number of PV modules.
a). The maximum open voltage of each set of PV modules shall not exceed 550Vdc under
any condi�ons.
b). Each input of the inverter be�er use the same type of PV module in series.
c). Total output power of PV shall not exceed the maximum input power of inverter, each
PV modules shall not exceed the rated power of each channel.
Must follow below steps while shu�ng down the inverter:
1. Switch off the AC breaker.
2. Wait for 30 seconds, turn off the DC switch (if any), or simply disconnect the DC input
connector. The inverter will close the LCD and all indicators within two minutes.
When start up the single phase string inverter, should fellow below steps
：
1. First switch on the AC breaker.
2. Turn on the DC switch of the PV module, and if the panel provides sufficient star�ng
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 acceptable range, the inverter will generate energy.
NORMAL indicator light is on.
