Deye on-grid inverters

The SUN‑XL20‑B is the dedicated hub for Deye’s SUN‑XL02‑B series of photovoltaic optimisers, essential for enabling individual panel monitoring, rapid shutdown and full communication with the Deye Cloud platform. It works in conjunction with the SUN‑XL02‑B optimisers, enabling data transmission via photovoltaic cables (PLC), without the need for additional communication cables. ⚠️ Without this concentrator, the SUN‑XL02‑B optimisers cannot transmit data to the inverter or the cloud, and the rapid shutdown function is not active. Technical specifications Compatible model: SUN‑XL02‑B DC operating voltage: 12–15 V Maximum input current: 20 A Number of series connections: up to 4 strings of optimisers Compatible system: 1000/1500 V DC Operating temperature: –40°C to +65°C Protection rating: IP68 – excellent protection against water and dust Connectors: MC4 or compatible Communication: Power Line Communication (PLC) Weight: 1600 g Dimensions: 229×109×38 mm Certifications: CE Benefits ✅ Comprehensive monitoring: enables the transmission of performance data from each optimiser to the inverter and the Deye Cloud platform. ✅ Enhanced safety: enables the Rapid Shutdown function in the event of an emergency, in accordance with safety requirements. ✅ Simplified installation: communication takes place via existing PV cables – no additional cables required. Recommendation If you are using SUN‑XL02‑B optimisers, this concentrator is required to benefit from advanced monitoring and safety functions. One SUN‑XL20‑B concentrator is recommended for every 4 strings of optimisers.
