8kW Deye SUN-8K-SG05LP1-EU-SM2-P Single-Phase Hybrid Solar Inverter – 48V

The 8kW Deye SUN-8K-SG05LP1-EU-SM2-P Single-Phase Hybrid Solar Inverter is a high-capacity low-voltage hybrid inverter engineered for solar generation, battery storage, grid interaction and backup power. It delivers 8,000W rated AC output and works with 40–60V lead-acid or lithium-ion battery banks, making it particularly suitable for 48V-class energy-storage systems.

Its solar architecture features 2 MPPT trackers, while the 8kW model supports up to 12,800W maximum PV input power. The inverter provides up to 190A battery charging and discharging current, enabling high-rate energy storage and recovery. It also supports AC coupling, generator energy storage and configurable battery charging/discharging periods.

Macire supplies the Deye inverter with technical guidance for correct battery, PV-array and protection-system sizing.

Installation & Engineering Notes

The SUN-8K-SG05LP1-EU-SM2-P requires professional system design. PV strings must remain within the inverter’s specified 500V maximum PV input voltage and 150–425V MPPT operating range.

Battery cables must be correctly sized for the inverter’s high DC current capability. Compatible lithium batteries should use the appropriate BMS communication configuration.

Install suitable AC/DC isolators, breakers, surge protection, earthing and correctly rated cabling. The inverter itself carries an IP65 rating, but installation location, ventilation and manufacturer clearances must still be respected.

Macire can assist with inverter, battery, solar-panel and protection-system sizing.

Care, Maintenance & Operations

1. Keep the inverter ventilation areas unobstructed.
2. Periodically inspect PV, battery and AC connections.
3. Monitor system warnings through the inverter display or configured monitoring platform.
4. Maintain lithium batteries according to their manufacturer’s requirements.
5. Check DC and AC protection equipment periodically.
6. Keep firmware and battery communication settings correctly configured.
7. Avoid continually operating the system beyond its designed load.
8. Have abnormal faults investigated by a qualified solar technician.
