The Intelligent Monitoring System for Off-grid Solar Power System

 
 
In recent years, solar energy has become a popular renewable energy source because of its falling costs and improving efficiencies. In these days, more and more people chose to install an off-grid solar power system. An off grid solar power system comes in various capacities for different type of applications, such as, small home, 2-3 floor homes, shops, offices, school, warehouses, and more.
 
To monitor and regulate the operation of such an off-grid solar power system, it is necessary for users to install an intelligent monitoring system.
 
The following picture shows the whole intelligent monitoring system.

The intelligent monitoring system for off-grid solar power system consists of four parts: solar controller, 2G/4G communication modules, cloud server and client (mobile App, Web).
 
IoT solar controller: It is and intelligent solar controller which can collect the data of current, voltage, temperature, power generation and power consumption of the system (battery panel, battery, load, etc.). It transmits the data to the communication module through the interface, and can receive commands such as switch, load carry, parameter adjustment, etc. from the client.
 
Communication module: It transmits the information of the solar controller to the cloud platform through the network, which is a bridge connecting the controller and the cloud platform. The platform supports various communication methods such as 2G, 4G, NB-Iot, and Ethernet.
 
Cloud server: Cloud servers are deployed on Alibaba Cloud and Amazon Cloud and are responsible for system scheduling, data storage and data processing.
 
Client: The client includes Web and mobile APP. Users can check the data of cloud services through the client side, and can control the switch load and adjust parameters through the cloud server.
