Why Choose This Product?
The Deye SUN-6K-SG04LP1-EU combines a 6 kW single-phase output with dual MPPT tracking, low-voltage battery support and flexible energy-management options. Its AC-coupling, generator-support and parallel-operation capabilities make it suitable for new installations as well as selected system expansions and retrofits.
Important Notes
- Battery compatibility, BMS communication and charging settings must be confirmed before installation.
- PV array voltage and current must remain within the inverter’s specified operating limits.
- Parallel operation and generator integration require compatible equipment and correct system configuration.
- The Arc Fault Circuit Interrupter (AFCI) is listed as an optional feature and should not be assumed to be included.
- The applicable 5-year or 10-year warranty depends on the final installation site and Deye’s warranty policy.
- Installation and commissioning must be completed by a suitably qualified electrician or solar installer in accordance with applicable South African requirements.
