Commissioning
6.1 Inspection before Commissioning
Check the following items before starting the inverter:
• All equipment has been reliably installed.
• DC switch(es) and AC circuit breaker are in the "OFF" position.
• The ground cable is properly and reliably connected.
• The AC cable is properly and reliably connected.
• The DC cable is properly and reliably connected.
• The communication cable is properly and reliably connected.
• The vacant terminals are sealed.
• No foreign items, such as tools, are left on the top of the machine or in the junction box (if
there is).
• The AC circuit breaker is selected in accordance with the requirements of this manual
and local standards.
• All warning signs & labels are intact and legible.
6.2 Commissioning Procedure
If all of the items mentioned above meet the requirements, proceed as follows to start up the
inverter for the first time.
step 1 Rotate one DC switch of the inverter to the "ON" position. When the indicator blinks blue
slowly, turn the other DC switches to the “ON” position.
The indicator is red if there is no power supply from the grid. Report the grid power
failure (the fault information can be viewed on the iSolarCloud App, see “Records”
for details). The fault is automatically cleared when the AC circuit breaker between
the inverter and the grid is closed.
step 2 Close the AC circuit breaker between the inverter and the grid.
step 3 Install the iSolarCloud App, see " 7.2 Installing the App " for details.
step 4 Set initial protection parameters via the iSolarCloud App when the inverter is connected to
the grid for the first time (see Step 4 in " 7.3.2 Login Procedure " for details). If the irradiation
and grid conditions meet requirements, the inverter normally operates.
