It is an Optimizer Concentrator that acts as the central communication and safety hub for Deye PV optimizers. It manages data and safety signals for up to 4 strings of panels.
No. The SUN-XL20-B is specifically designed to work with Deye SUN-XL02-B optimizers. It cannot function as a standalone device for other solar systems.
It can manage up to 4 strings, with each string typically supporting up to 30 modules, allowing for centralized control of large residential or small commercial arrays.
It uses PLC (Power Line Carrier) technology. This means it sends and receives data directly through the existing DC solar cables, so you don't need to run any extra data wires on your roof.
Yes. It features a robust IP68-rated enclosure, meaning it is completely dust-tight and protected against prolonged immersion in water, making it suitable for any outdoor environment.
Yes. It is the primary controller for the Rapid Shutdown function across all connected optimizers, ensuring the system meets the highest safety standards for emergency response.
The unit typically receives power from the inverter or a dedicated DC supply within the operating range of 12V - 15V.
Absolutely. When connected to a Deye-compatible inverter or logger, the SUN-XL20-B transmits individual module data to the Deye Cloud App for real-time monitoring.
No. It is designed for easy DIN rail mounting. Since it uses PLC communication, the 'installation' mostly involves connecting your string cables and the low-voltage power supply.
The SUN-XL20-B comes with a standard 12-year warranty, built with high-quality industrial components to match the long life of your solar installation.
