Deye SUN-M225G4-EU-Q0

2200W microinverter with quad MPPT, IP67 protection, and 10-year warranty.

Models Covered: SUN-M220G4-EU-Q0, DEYE-SUN-M225G4-EU-Q0

Manufacturer: Ningbo Deye Inverter Technology Co., Ltd

Application: The Deye SUN-M220G4-EU-Q0 is a module-level micro-inverter in the Micro (M) series, single-phase, delivering 2200 W of rated AC output active power. Installers pairing it with modern large-format panels get real headroom: each of its four MPPT inputs handles 18 A of operating current and tolerates 27 A of short-circuit current, so high-current cells are never clipped. One string sits on each tracker, panels may be rated between 210 W and 770 W, and total PV input may reach 3080 W. Conversion peaks at 96.5% with a 96.0% European weighted figure, while MPPT tracking efficiency stays above 99%. AC output is 10/9.6 A at 220/230 V, with three inverters allowed on a shared branch. The IP67 housing spans 358 x 255.5 x 36.5 mm at 5.2 kg, is fan-free, and works from -40 to 65 degrees Celsius. A stated 10-year warranty applies.

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 France that is CRE France. Confirm the grid code, import requirements and any local certification with them, or with us, before you order.
