Deye SUN1 1 5 2 2 2 2 5 2 7
Built for residential solar installations, this single-phase inverter from Chinese manufacturer Deye delivers impressive performance in a compact package. With a maximum efficiency rating of 97.5% and European efficiency of 97.0%, it maximizes energy conversion while minimizing losses. The unit handles DC input voltages up to 550V with an MPPT voltage range spanning 40-500V, making it compatible with various solar panel configurations.
What sets this inverter apart is its robust construction combined with lightweight design - weighing just 5.7kg while maintaining IP65 weather protection. The single MPPT channel supports up to 20A input current, and it operates reliably across extreme temperatures from -25°C to +65°C. Output quality remains excellent with total harmonic distortion kept to just 3%, ensuring clean 220/230V AC power at standard 50/60Hz frequency for seamless grid integration.

Frequently asked questions
What does the Deye SUN1/1.5/2/2.2/2.5/2.7 designation actually refer to?
The Deye SUN1/1.5/2/2.2/2.5/2.7 designation groups a range of single-phase string inverters from 1 kW to 2.7 kW, so the delivered power follows the variant chosen. This entry stores one shared set of figures for a non-isolated single-phase unit; they characterise the platform rather than any single rating within that range.
What grid does the Deye SUN1/1.5/2/2.2/2.5/2.7 connect to?
The Deye SUN1/1.5/2/2.2/2.5/2.7 is recorded as a single-phase inverter delivering 220/230 V at 50 or 60 Hz, which is the ordinary household supply in most markets, so no three-phase connection is required. Those frequency and voltage pairs are alternative grid configurations. Its total harmonic distortion is given as 3 percent.
How wide is the MPPT window of the Deye SUN1/1.5/2/2.2/2.5/2.7?
The Deye SUN1/1.5/2/2.2/2.5/2.7 tracks from 40 V to 500 V and tolerates 550 V of maximum DC input voltage. A 40 V lower limit is unusually low, so the inverter keeps harvesting from very short strings and starts earlier at dawn, while every string must still stay below 550 V at the coldest temperature expected on site.
How many MPPT inputs does the Deye SUN1/1.5/2/2.2/2.5/2.7 have?
The Deye SUN1/1.5/2/2.2/2.5/2.7 provides one MPPT input rated for a maximum DC current of 20 A. A single tracker means the whole array is optimised as one block, so it suits a single unshaded roof plane; splitting production across two orientations would lose energy that a two-tracker inverter would have recovered.
What efficiency figures are published for the Deye SUN1/1.5/2/2.2/2.5/2.7?
The Deye SUN1/1.5/2/2.2/2.5/2.7 is listed at 97.5 percent maximum efficiency and 97.0 percent European efficiency. The half-point gap between them is small, which means conversion losses stay fairly flat across the load range; for annual yield modelling the weighted 97.0 percent European figure is the sensible one to apply.
Where can the Deye SUN1/1.5/2/2.2/2.5/2.7 be installed?
The Deye SUN1/1.5/2/2.2/2.5/2.7 is rated IP65 and specified from -25 to +65 degrees Celsius, so an exterior wall is within its declared envelope, though shade from direct midday sun helps keep it cool. Its 5.7 kg makes it a straightforward single-handed installation on a standard mounting bracket.
