Fed by three to four panels
A series string of 330 W modules at 80-380 V DC drives the unit directly, drawing under 10 A. The 208-240 V single-phase line stays as backup.

Solar Air ConditionersModel DGA2-ACDCBLW-12K
A 12,000 BTU PV-direct split sized for rooms of 12 to 20 m², fed by three to four 330 W modules at 80-380 V DC and quiet at under 42.5 dB indoors.
In stock
A series string of 330 W modules at 80-380 V DC drives the unit directly, drawing under 10 A. The 208-240 V single-phase line stays as backup.
Rated 3,510 W of cooling at T1 for 940 W drawn, an EER of 3.75/12.75. Output modulates between 3,000 and 13,300 BTU as the room load moves.
Reverse-cycle heating rated 4,100 W at a COP of 3.50/11.95, so the same unit covers cold nights instead of a second appliance.
A BLDC 15 W indoor fan with four speeds from 350 to 540 m³/h keeps the room side quiet; the outdoor unit stays below 52 dB.
The grid draw can be capped anywhere between 0 and 600 W, so the AC side never asks for more than the supply behind it can give.
The DGA2-ACDCBLW-12K is the smallest of the three PV-direct air conditioners in the ACDCBLW line, sized for a bedroom, a home office or a back room of 12 to 20 m². Its DC side takes a string of three to four 330 W modules at 80-380 V and under 10 A, so the compressor works on panel power through the hours the sun is doing the damage. The single-phase 208-240 V, 50/60 Hz connection covers the rest, and an AC power limiter settable from 0 to 600 W decides how much of that supply the unit may take. Rated cooling is 12,000 BTU, or 3,510 W at T1 for 940 W of input, an EER of 3.75/12.75. Under T3 conditions it still returns 9,900 BTU. The same box heats to 14,000 BTU at a COP of 3.50/11.95 and strips 1.3 L/h of moisture from the air, on R410A with an electronic expansion valve and a Highly WHP04200 twin-rotary variable-speed compressor. We are an authorised Deye distributor and supply the DGA2-ACDCBLW-12K from our own stock, with technical support before and after the sale.

Deye gives it an application area of 12 to 20 m², which covers a typical bedroom, a home office or a small shop floor. Beyond 20 m² the 17,300 BTU DGA1-ACDCBLW-18K takes over.
Three to four 330 W modules wired in series. The DC input works over 80-380 V at under 10 A, so the string voltage has to land inside that window.
It also accepts a single-phase 208-240 V, 50/60 Hz supply, so mains covers the hours the panels cannot. How much it may draw from that side is set by the 0-600 W AC power limiter.
It carries a T3 as well as a T1 climate rating and works from -10 to 58 °C. At T3 it returns 2,910 W, or 9,900 BTU, for 1,050 W of input, an EER of 2.75/9.45.
Up to 15 m of refrigerant pipe with a level difference of no more than 8 m. Three metres of pipe and 4 m of connection wire are supplied; the gas and liquid lines are 3/8 in and 1/4 in.
