Installation and Connection
3.1 ShineMaster installation environment requirements
The installation environment requirements of ShineMaster and communication with
other devices:
(1) Indoor installation, temperature - 40 ~ 60
℃
, avoid moisture and direct sunlight.
(2) Cable RS485 in maximum 500m.
(3) The standard version :The length of communication cable to the switch or router is
not more than 100m
。
(4) The 4G version: Using 4G communication mode, must connect to 4G antenna, insert
the 4G sim card.
3.2 ShineMaster installation
3.2.1 Installation Procedure

Connect cables between RS485 port and RS485 port on ShineMaster (please refer to
3.3.1 below for details)
(1)
(2)
(3) Communication mode options
The standard version: Connect the network cable
The 4G version: Connect 4G antenna, insert the 4G sim card.
(4) Connect the Power supply
3.3 Connect to the photovoltaic device
ShineMaster can communicate with the inverter, weather station, smart meter, combiner
box and other photovoltaic devices to collect the data.
1.ShineMaster (leader) communicates with follower devices via RS485 wired connection.
T+ on the RS485 port of the device corresponds to A1 or A2 on the ShineMaster 485
port, T- and ShineMaster 485 on the RS485 port of the follower device, corresponding to
B1 or B2. The following is a schematic diagram of the connection between the
ShineMaster and the inverter:
Note: the RS485 shielded wire must be ground (PE) for long distance communication, so
as not to affect the communication stability.
