6 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.
NOTICE
• Strictly follow the preceding sequence. Otherwise, the product may be damaged, and
the loss caused is not covered by the warranty.
•
If the DC side is powered up while the AC side is not, the inverter will report a fault
named “Grid Power Outage” (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.
•
Before closing the AC circuit breaker between the inverter and the power grid, use
a multimeter that is set to the AC gear to ensure that the AC voltage is within the
specified range. Otherwise, the inverter may be damaged.
