Deye SUN-XL20-B Optimiser Concentrator 4 Strings with Rapid Shutdown and PLC IP68
The Deye SUN-XL20-B concentrator is the unit that completes a module-optimiser architecture: it collects the data of the Deye SUN-XL02-B optimisers by PLC over the PV cables and passes it to the monitoring platform, while at the same time enabling the string rapid shutdown function required on site and during maintenance or firefighting operations.
A single unit serves four series strings, works in 1000V and 1500V systems with a 12-15V DC operating voltage and uses MC4 connectors, so it slots into the existing wiring without dedicated data lines. The IP68 housing and the -40/+65 °C range allow permanent field installation, under the modules or close to the string box. It is used with the Deye single-phase and three-phase string inverters on which the SUN-XL02-B optimisers are fitted. CE certified.
