The Deye SUN-M40G4-EU-Q0-I is a 400 W G4 microinverter built for single-module residential PV where a 400 W AC ceiling matches mainstream panel sizing. Because this model serves one PV module with its own MPPT, module mismatch and local shading remain isolated at the panel level instead of affecting a whole string. The official datasheet specifies a 210–560 W module-power range, 25–55 V MPPT window and 15 A maximum operating input current, making the DC side easy to match to modern modules. On the AC side it delivers 400 W and permits up to 13 units on a branch under the published configuration. Integrated Wi‑Fi, IP67 environmental protection, ≤25 dB acoustic level and natural cooling suit visible residential locations, while the -40°C to +65°C operating range supports year-round outdoor installation. For projects where module-level visibility, simple expansion and compact hardware matter, this 400 W version offers a clean, precisely sized solution.
