Respect all safety instructions inside the device and in this manual.
Respect all safety instructions prescribed by the manufacturer of devices
connected to the container.
WARNING:
Grid-connection of the container can be done only after receiving approval from the
local utility grid company and by qualified personnel.

is stopped.
7.2 Requirements of Commissioning
Before commissioning, installation of the two inverters and the power distribution cabinet inside
the container should be checked thoroughly.
Ensure all the cable connections are secure and all bolts are fixed properly.
Ensure DC side voltage meets inverter requirements and the polarity is correct.
Ensure AC side voltage meets inverter requirements.
Ensure all cable connections meets related standards and requirements.
Ensure the system is properly grounded. Ground resistance is important for the whole system
so that before commissioning, make sure the ground resistance is less than 4Ω.
WARNING:
Make sure the emergency stop button of each inverter is released, all AC & DC
switches are disconnected and all micro-circuit breakers inside the power distribution
cabinet are disconnected before commissioning.
