Compact Smart Renewable Energy Management & Grid Tie Box
The increasing need of a sustainable energy means that smaller grid friendly and intelligent systems are needed that can effectively handle renewable energy. Traditional renewable installations usually need much space, are associated with a high price and lack easy incorporation with smart control and real-time monitoring systems. In this paper, the author introduces the development of a small smart renewable energy control platform comprising of solar energy collection, intelligent control and IoT-based monitoring. The system consists of the voltage regulation DC to DC converter, a battery storage, and the main controller is an Arduino Uno (ATmega328P). Total measurements are an environmental and electrical parameter with DHT11, voltage and current sensors. A local monitoring is available on an LCD whereas an ESP32 can allow connectivity to the cloud where real-time uses of an IoT can be realized. Relay drivers are used to provide automated load control and electronic grid switching. Its effectiveness and scalability 92% conversion efficiency, voltage stability (in the range of ±2%), and response time (less than 150 ms) have been proven by experimental results.
