Deye On-Grid Inverters 15-25 kW SUN-15/18/20/22/23/25K-G05

15kW three phase string inverter with 98.5% efficiency and dual MPPT trackers.

Models Covered: DEYE-SUN-15K-G05, DEYE-SUN-18K-G05, DEYE-SUN-20K-G05, DEYE-SUN-22K-G05, DEYE-SUN-23K-G05, DEYE-SUN-25K-G05

Manufacturer: Ningbo Deye Inverter Technology Co., Ltd

Application: The Deye SUN-15K-G05 is a 15 kW three-phase string inverter in the G05 series, connected 3L+N+PE at 220/380 or 230/400 V for a villa compound, a clinic or a small commercial roof. Installers set it up over RS485 or RS232 and then follow it through a GPRS, Wi-Fi, Bluetooth, 4G or optional LAN monitoring module. Its rated AC output active power is 15000 W, with 16.5 kVA of apparent power and 22.7/21.7 A of rated output current. The DC side is deliberately asymmetric: two MPPTs split strings 1+2 and draw 20+26 A, accepting up to 19.5 kW of PV input power against a 1000 V maximum, so one long south string and two shorter roof faces can share a single machine. Tracking spans 200-850 V from a 250 V startup. Intelligent air cooling stays under 40 dB, and the 15 kg IP65 unit carries a stated 5-year warranty. We are an authorised Deye distributor and supply the SUN-15K-G05 from our own stock, with technical support before and after the sale.

Figures on this page are the manufacturer's own, measured at the test conditions the datasheet states — they do not change by country. What changes is the approval that has to be met before the unit is energised: in the UAE that rests with the local authorities (DEWA, ADDC, SEWA). Confirm the grid code, import requirements and any local certification with them, or with us, before you order.
