Installation
Preparation before Installation
Adapter inverter: single-phase residential inverter and three-phase string
inverter manufactured by SUNGROW.
The inverter has been installed correctly and the DC side can be powered on
(For details, refer to the corresponding user manual.).
Installation Steps
Take out the wireless communication module from the packing case, and
identify the correct connection manner.

Insert the wireless communication module into the network port (COM)
at the bottom of the inverter until it snaps into place with a "Click" sound.
If the module is still loose, remove it from the communication port and
check whether the port is damaged. If the port the normal, reinsert the
wireless communication module.
The wireless communication module can be plugged in and out
without switching off the inverter.
If you need to collect information of several inverters, connect the
inverters in the daisy chain manner through the RS485 communication
cables as described in the corresponding user manual.

Press down the buckles on both sides when plugging/unplugging
the module. Frequent plugging/unplugging operation is not
recommended.
•If the wireless communication module needs to be replaced
during operation, replace it via the iSolarCloud App (For details,

Inspection Before Commissioning
Check the following items before
Environment inspection
The wireless communication module is installed in a place convenient for
operation and maintenance.
Ensure again that the wireless communication module is firmly in place.
The installation environment is well-ventilated.
The wireless communication module is correctly connected to the
inverter.
The cables are appropriately routed and well protected against
mechanical damage.
Make sure the inverter to be connected has a correct SN number
(product serial number).
Commissioning Steps
When all the foregoing items meet requirements, start the wireless
communication module for the first time.
Connect the AC circuit breakers.
Connect the DC switches of the inverter.
If the sunlight is sufficient, the PV panel starts to supply DC power to the
inverter. When the DC voltage exceeds the start voltage of the inverter,
the inverter will automatically start.
Wait about 15s for the wireless communication module to start
automatically.
Download the iSolarCloud APP and configure the parameters of the
inverter connected with the wireless communication module. For details,
refer to the corresponding quick operation guide.
