Deye SUN-XL02-B Power Optimiser 700W with Module-Level Monitoring IP68
The Deye SUN-XL02-B power optimiser is the module-level monitoring and rapid shutdown version of the SUN-XL02 family. It applies MPPT to each individual panel, so partial shade, soiling, differences in orientation or ageing no longer drag the whole string down, and at the same time it sends per-module production data to the monitoring platform: the right configuration for roof systems that need fine diagnostics and safety during maintenance.
It handles up to 700W, 80V and 15A per module with a peak efficiency of 99.5%, and communicates by PLC over the PV cables up to 350 m to the concentrator. One concentrator handles up to 4 strings of at most 25 modules each. It must be paired with the Deye SUN-XL20-B concentrator, which completes the rapid shutdown function, and is installed on Deye single-phase and three-phase string inverters. IP68 housing with MC4 connectors and CE certification.
