    Application of Acrel ACR10R Series with AWT100-4G in PV inverters in India

    2024-01-23

    Abstract: Solar energy is a rapidly growing energy source in the world and the most easily available renewable energy source. The market share of the use of solar energy to transmit electricity to the grid is still growing. At the same time, grid companies usually require the photovoltaic grid-connected system to be an irreversible power generation system, that is, the electricity generated by the photovoltaic grid-connected system is consumed by the local load. It is self-generated and used. In the grid-connected power generation and energy storage system, with the external environment is constantly changing, in order to prevent the photovoltaic grid-connected system from generating reverse power, the system needs to perform reverse current detection, and regulate the power generation of the system by real-time monitoring of the power signal on the low-voltage outlet side of the distribution transformer power, so as to achieve the anti-backflow function of the photovoltaic grid-connected system. This article introduces the application of ACRELACR10R and AWT100-4G in a pump industry in India.


    1.Project Overview

    Indian customers plan to produce inverters by themselves. They need inverters and energy meters for government tender. They need ACR10T to monitor the electricity consumption of the plant equipment and use electricity meters to detect the energy consumption of each device effectively.AWT100-4G use MQTT protocol to connect the platform

    6.In conclusion


    ACR10R it has a variety of peripheral interface for user to choose:withRS485 communication interface, MODBUS-RTUprotocol can meet the needs of communication networkmanagement;The function of “ remote signal” and “ remote control” of circuit breaker switchcan be realized with switch quantity input and relay output.Theinterfaces with switch input and relay output can realize the remote signalingand remote control of the circuit breaker switch. It is very suitable for real-timepower monitoring system with an LCD display and the panel buttons to realizethe setting and control of parameters for PV inverter system.
