Deye SUN70 75 80 90 100 110KG03 70110KW Three Phase 6 MPPT
Built for demanding commercial and industrial solar installations, this high-performance three-phase inverter delivers exceptional efficiency with its 98.8% maximum conversion rate and 98.2% European efficiency rating. The advanced design incorporates 6 independent MPPT channels, each capable of handling up to 40A DC input current across a wide voltage range of 200-850V, making it ideal for complex rooftop arrays and large-scale photovoltaic systems.
Engineered for reliability in harsh environments, the unit features robust IP65 weatherproof protection and operates effectively across temperatures from -25°C to +60°C. Its non-isolated topology ensures optimal power conversion while maintaining low total harmonic distortion at just 3%. The flexible AC output configuration supports both 220/380V and 230/400V systems at 50/60Hz frequencies, accommodating various grid requirements across different regions.

Frequently asked questions
How many versions does the Deye SUN70-110KG03 designation cover?
The Deye SUN70-110KG03 designation covers six ratings, from 70 kW through 75, 80, 90 and 100 kW up to 110 kW, rather than a single machine. The figures held for this entry are those common to the family: six MPPT channels, a 200 V to 850 V tracking window, 1000 V maximum DC input and 40 A per channel.
What do six MPPT channels give the Deye SUN70-110KG03?
Six independent trackers let the array feeding the Deye SUN70-110KG03 be broken into six groups, so on a large commercial roof separate pitches, azimuths or shading zones each find their own maximum power point. Every one of the six channels takes up to 40 A of DC input current, so paralleling is planned tracker by tracker.
What are the string voltage limits of the Deye SUN70-110KG03?
The Deye SUN70-110KG03 tracks only between 200 V and 850 V while tolerating 1000 V of maximum DC input voltage. That gap matters: a string can sit below the 1000 V ceiling and still climb past the 850 V tracking limit on a cold morning, so string length is checked against 850 V, not only the ceiling.
How is the Deye SUN70-110KG03 handled during installation?
At 81 kg the Deye SUN70-110KG03 goes beyond a comfortable two-person lift and normally calls for lifting gear to reach its mounting bracket. Its IP65 rating and declared -25 to +60 degrees Celsius operating range allow an outdoor position. It is recorded as a non-isolated design, without an internal transformer between array and grid.
How much energy does the Deye SUN70-110KG03 lose in conversion?
The Deye SUN70-110KG03 is rated at 98.8 percent maximum efficiency and 98.2 percent European efficiency, so roughly 1.8 percent of the DC energy the array delivers is lost on the way to the grid across a typical year. On a plant of this size that difference is worth quantifying when comparing candidate inverters.
What grid does the Deye SUN70-110KG03 connect to?
The Deye SUN70-110KG03 is a three-phase inverter listed for 220/380 V or 230/400 V networks at 50 Hz or 60 Hz. Each pair of voltages describes one four-wire system, phase-to-neutral and phase-to-phase, while the 50/60 Hz entry marks two alternative grid frequencies. Total harmonic distortion of the injected current is given as 3 percent.
