Deye SUN-8K-SG05LP1-EU single-phase hybrid inverter

Description

Optimise your solar energy production and consumption with the SUN-8K-SG hybrid inverter. Designed for homes and small businesses, it maximises self-consumption of photovoltaic energy and reduces electricity costs. The inverter distributes solar energy directly to appliances during the day and stores the surplus in the battery for later use. In the event of a power cut, the connection to a generator ensures an uninterrupted power supply. Its RS485/CAN port enables smart, automated management of your energy. Choose a reliable, sustainable and high-performance solution for your energy system.

What this inverter actually does

The Deye SUN-8K is the intelligent heart of your solar installation. It does three things at once:

• It converts the energy from your solar panels into usable electricity (230 V AC).
• It stores the surplus in a 48 V battery (LiFePO4 lithium or lead-acid) for use in the evening or at night.
• It automatically switches to the battery in the event of a mains power cut, without any noticeable interruption.

The result: you use your own generated power first, you no longer depend on the grid for your daily needs, and you are protected in the event of a power cut.

Key features

1. Adjustable power

The SUN-8K-SG delivers 8 kW nominal power, ideal for residential and light commercial energy needs. Easily adjust the power output to match your consumption.

2. Maximising self-consumption

Power your appliances directly with solar energy and store the surplus in the battery to reduce your reliance on the grid and maximise your energy savings.

3. Smart energy management

The system prioritises energy consumption in real time and optimises battery storage, ensuring a constant supply of electricity.

4. Reliable backup power

In the event of a power cut, the connection to a generator ensures uninterrupted power supply, providing security and peace of mind for your operations.

5. RS485/CAN communication port

Enables smart monitoring and remote software updates, ensuring optimal operation and simplified maintenance.

6. Quick and intuitive installation

Designed for quick and easy deployment, reducing installation time and costs.

7. Advanced monitoring

Access real-time data on production, consumption and battery status for proactive and efficient energy management.

Conclusion

The SUN-8K-SG combines power, flexibility and smart technology to maximise energy efficiency. Perfect for homeowners and small businesses, it helps reduce electricity costs whilst contributing to a sustainable lifestyle.
