Off grid and grid connected hybrid residential solar photovoltaic system
This all-in-one hybrid system is engineered for resilience, efficiency, and smart energy management in a residential setting.
-
Dual-Mode Operation: Functions intelligently in both grid-tied and off-grid modes. When the grid is up, it operates as a grid-tied system with battery storage. During a power outage, it automatically and seamlessly disconnects from the grid (islanding) and powers the home from the battery and solar panels, ensuring an uninterrupted electricity supply.
-
Maximized Self-Consumption & Savings: The system's core intelligence lies in directing solar energy to power the home first. Any excess energy not used immediately is stored in the battery bank instead of being sold back to the grid at a lower rate. This maximizes the use of your free solar energy, drastically reducing reliance on expensive grid power, especially during peak evening hours.
-
Intelligent Energy Management: A sophisticated hybrid inverter with smart software manages the entire energy ecosystem. Users can set preferences (e.g., charge battery from grid during off-peak hours) and monitor performance in real-time via a user-friendly mobile app, giving complete control over household energy use and costs.
-
Backup Power Resilience: Provides reliable backup power for critical home loads during grid outages. Unlike traditional generators, it is silent, instant, and runs on clean, free solar energy or stored battery power, keeping lights, refrigerators, and communication devices running.
-
Scalable & Future-Proof Design: The system is modular, allowing homeowners to start with a base configuration and easily expand battery storage capacity or add more solar panels in the future as energy needs grow or budgets allow.
-
Grid Support & Revenue Generation (where applicable): In regions with favorable net metering or feed-in tariff policies, the system can still export surplus solar energy to the grid after the battery is full, potentially generating credit or revenue.
