Frequently asked questions
What do the three power ratings of the Deye SUN40-45-50KG04 three-phase range mean?
The designation covers a family rather than a single unit: the figures recorded for the Deye SUN40-45-50KG04 three-phase range are 40000 W, 45000 W and 50000 W of nominal AC power. Choosing between them is a question of array size, since all three share the same four-tracker platform and the same DC limits.
How much overload headroom does each Deye SUN40-45-50KG04 rating have?
Each rating in the Deye SUN40-45-50KG04 three-phase range pairs with its own maximum: 40000 W nominal with 44000 W, 45000 W with 49500 W and 50000 W with 55000 W. The ratings are not interchangeable, and the consistent ten percent margin is what an oversized array can deliver on cold, bright days.
How much DC current can the Deye SUN40-45-50KG04 three-phase range take?
Every version of the Deye SUN40-45-50KG04 three-phase range carries four MPPT channels rated at 40 A of DC input current each. That current budget is shared identically across the 40, 45 and 50 kW ratings, so the smaller units effectively have more DC headroom per kilowatt of AC output than the largest one.
Does string design change between the Deye SUN40-45-50KG04 power ratings?
No. The MPPT window of 200 V to 1000 V and the 1100 V maximum DC input voltage apply across the whole Deye SUN40-45-50KG04 three-phase range. A string layout verified against 1100 V at minimum temperature therefore holds if the chosen rating changes, which makes the family convenient when a project is resized late.
Is the Deye SUN40-45-50KG04 three-phase range suitable for a house?
Rarely. The Deye SUN40-45-50KG04 three-phase range starts at 40000 W and needs a three-phase supply of 220/380 V or 230/400 V at 50 or 60 Hz, and the unit weighs 39 kg. Those figures point at commercial buildings, farms and industrial roofs rather than an ordinary single-phase domestic connection.
What quality of AC current does the Deye SUN40-45-50KG04 three-phase range inject?
Total harmonic distortion for the Deye SUN40-45-50KG04 three-phase range is given as 3 percent, comfortably inside what grid codes normally ask of a generator of this size. The unit is also recorded as non-isolated, meaning no galvanic isolation transformer, which keeps the 98.7 percent maximum efficiency and the 39 kg mass achievable together.
