Thescenario is based on a small on-grid Solar PV system without DC energy
Thepurpose was to online monitor all common electricity parameters for each solar panel string to check their working efficiency and status for maintanance.
Forsite situation, suppose we have 3 inverters, 48 solar panel strings 576 solar panels in For each solar panel string consisted of 12 solar panels and connect to a general DC circuit for power distribution. We will target this DC circuit for monitoring. [Rated current 12A DC, rated voltage 600Vdc]. Also, each inverter connect to 16 solar panel strings.
Forthe places that we gonna install the energy meter and IoT gateway, they are covered by stable 4G signal.

CommunicationStructure&Logic
(1)4G Communication could be served as one of the final data upstream methods by sending the data to cloud server deployed in Internet so that Acrel IoT System could be interact with these data collected by bottom metering devices like Energy Meter
(2)AWT100-4GHW gateway support upstream of 4G communication with MQTT and MODBUS- protocol and downstream of RS485 communication based on MODBUS-RTU protocol. AGF-M16T support upstream communication of RS485 communication based on MODBUS-RTU protocol.
(3)Based on the communication described in item (2), Acrel AWT100-4GHW gateway could receive the data from ADL200/C energy meter using RS485 communication while sending the data further to cloud server using 4G upstream communication. Thus accomplish a complete communication from bottom metering devices to top system software. Hardware Devices Overview [Energy Meter & Paired IoT Gateway]Model1:AWT100-4GHWIoT4GSmartGateway
