The components of the set in detail

The Deye SUN-8K-SG05LP3-EU-SM2 hybrid inverter

The heart of the system delivers 8 kW continuous three-phase power and intelligently controls the energy flow between the PV system, battery, home network, and public grid. With 2 MPP trackers, a maximum efficiency of 97.6%, and a backup power function (peak output up to 16 kW for 10 seconds), it ensures reliable power supply even during a grid outage. Protective features such as anti-islanding detection, AFCI capability (optional), and an IP65 housing make it robust and safe.

The Deye AI-W5.1-B battery storage

The 5.12 kWh battery module uses safe, cobalt-free LiFePO4 cell chemistry and offers a recommended depth of discharge of 90%. The integrated battery management system monitors every cell in real time, ensuring a balanced charge and discharge curve. With over 6,000 full cycles, a 10-year warranty, and a wide operating temperature range of -20°C to +55°C, this battery storage is a long-lasting partner for maximizing your self-consumption rate.

The Deye AI-W5.1-Base battery base

The sturdy base forms the foundation of the storage solution. It safely lifts the system off the ground, protects against moisture, and ensures a proper fit for all additional modules – without extra screws or complex mounting.

The Deye AI-W5.1-PDU1 connection unit

The Power Distribution Unit securely connects the battery to the hybrid inverter and provides all power and communication interfaces. An LED display shows the system status at a glance, simplifying installation, maintenance, and fault diagnosis.
