The Deye SUN-1K-G04P1-EU-AM1 is a 1 kW single-phase string inverter (L+N+PE) from the G04P1 series, the smallest step in the String (G) line. Its 80 V start-up voltage matters most on a small array: with only one string on one MPPT the tracker has to work from a low module count, and the 70 V to 500 V window keeps that string productive from early morning until dusk. At 1000 W of rated AC output active power it is sized for a two-room flat, a shop front or a caretaker's cabin, covering lighting, a refrigerator and fans. Up to 1300 W of PV can be wired in, and the input withstands 30 A of short-circuit current. Grid output is 220/230 V, 4.6 A rated and 1100 VA maximum. At 5.6 kg the IP65 unit is a one-person wall mount, natural cooling holds it under 35 dB, and a DC switch is built in. The SUN-1K-G04P1-EU-AM1 carries a stated 5-year warranty. We are an authorised Deye distributor and supply the SUN-1K-G04P1-EU-AM1 from our own stock, with technical support before and after the sale.
