Deye SUN7 7 5 8 9 10 10 5KG 710 5KW Single Phase 2 MPPT
Built for residential and small commercial solar installations, this Chinese-manufactured inverter delivers impressive performance with its 10kW nominal output and peak capacity of 11.55kW. The unit achieves exceptional efficiency ratings of 97.7% maximum and 97.2% European efficiency, ensuring minimal energy loss during conversion.
Dual MPPT channels provide maximum flexibility for panel configuration, accommodating DC voltages from 70V to 500V with up to 26A input current per channel. The robust IP65-rated enclosure weighs just 14.8kg while protecting internal components from dust and water ingress. Operating reliably across extreme temperatures from -25°C to +60°C, this single-phase inverter outputs clean AC power at 220/230V with only 3% total harmonic distortion, making it ideal for grid-tie applications where power quality is critical.

Frequently asked questions
Why does the Deye SUN7-7.5-8-9-10-10.5K-G track down to 70 V?
The Deye SUN7-7.5-8-9-10-10.5K-G has an MPPT range recorded as 70 to 500 V within a 550 V maximum DC input voltage. That unusually low 70 V floor means the inverter keeps regulating very short strings and stays productive at dawn, at dusk and under heavy cloud, when array voltage falls well below a conventional 150 V threshold.
What output is the Deye SUN7-7.5-8-9-10-10.5K-G rated for?
The designation of the Deye SUN7-7.5-8-9-10-10.5K-G spans 7 kW to 10.5 kW across six builds. The figures recorded for this entry are 10000 W of nominal AC power and 11550 W of maximum AC power. Note that 11550 W is 1.1 times 10.5 kW rather than 10 kW, so the two stored values appear to belong to different variants.
How heavy is the Deye SUN7-7.5-8-9-10-10.5K-G?
The weight recorded for the Deye SUN7-7.5-8-9-10-10.5K-G is 14.8 kg, which would make it a one-person wall mount. That is strikingly light for a unit listed at 10000 W nominal, and far below the figures held for Deye entries of comparable output, so it is worth checking against the datasheet of the exact variant.
What temperatures does the Deye SUN7-7.5-8-9-10-10.5K-G tolerate?
The Deye SUN7-7.5-8-9-10-10.5K-G is specified from -25 to +60 degrees Celsius and rated IP65, so an outdoor wall position stays within its declared limits across most European climates. The -25 degree floor is narrower than the -40 degrees recorded for several sibling Deye units, which only matters in genuinely severe winter locations.
What supply does the Deye SUN7-7.5-8-9-10-10.5K-G connect to?
The Deye SUN7-7.5-8-9-10-10.5K-G is recorded with one phase and an AC output of 220 or 230 V at 50 or 60 Hz. Those are alternative grid configurations for different markets rather than simultaneous outputs. Pushing 10000 W through a single phase is a large single-phase connection, so the local limit on that needs checking.
How much energy does the Deye SUN7-7.5-8-9-10-10.5K-G lose in conversion?
The Deye SUN7-7.5-8-9-10-10.5K-G is recorded at 97.7 percent maximum efficiency and 97.2 percent European efficiency, so a little under three percent of the array's DC energy is lost on the way to the meter. The European figure is the weighted one to use for yield work, and harmonic distortion is separately listed at 3 percent.
