Deye SUN-25K-G04 String Inverter 25 kW Three-Phase 2 MPPT CEI 0-21 IP65
The Deye SUN-25K-G04 string inverter is a three-phase grid-tie unit rated 25 kW for large residential PV systems, apartment buildings, workshops and small industrial roofs. Its 2 MPP trackers accept up to three strings each and a PV array of up to 32.5 kW, so two roof faces with different exposures can be covered while keeping DC oversizing.
A peak efficiency of 98.6%, IP65 protection and a weight of only 20.8 kg allow outdoor wall mounting, while the CEI 0-21 and EN 50549-1 certifications make it suitable for the Italian grid. It pairs with Deye DL1000B data loggers for Deye Cloud monitoring and with energy meters for the zero-export function.
