Deye DGA1-DC48V-12/18/24/09K

A 12,000 BTU battery-fed split for rooms of 12 to 20 m², wired to a 48 V bank and drawing 980 W at T1 with an EER of 3.60/12.25.

Models Covered: DGA1-DC48V-12K, DGA1-DC48V-18K, DGA1-DC48V-24K, DGA1-DC48V-09K

Manufacturer: Ningbo Deye Inverter Technology Co., Ltd

Application: The DGA1-DC48V-12K is the size most off-grid houses need first: 12,000 BTU for a room of 12 to 20 m², wired to nothing but a 48 V battery bank working between 46 and 58 V DC. Because the supply is stored energy, the unit is as useful at two in the morning as at noon, which is the practical difference between this model and a PV-direct machine. It produces 3,510 W of cooling at T1 for 980 W drawn, an EER of 3.60/12.25, and turns down to 200 W when the room is settled. Under T3 conditions output is 9,900 BTU. Heating is rated 13,300 BTU with 1,130 W of input, a COP of 3.45/11.75, and the coil removes 1.3 L/h of moisture. A GMCC ASN98D22UFZ rotary variable-speed compressor works a two-row coil, the outdoor fan moves 2,100 m³/h, and the pair weighs 32 kg net.

Key Features & Technical Highlights

  • 48 V bank, 46-58 V DC: The unit is powered by the battery directly, so it keeps cooling after dark on stored charge instead of waiting for the array.
  • 12,000 BTU from the bank: 3,510 W of cooling at T1 for 980 W drawn, an EER of 3.60/12.25, with the range running from 3,400 to 12,600 BTU.
  • GMCC ASN98D22UFZ compressor: A rotary variable-speed compressor on a two-row coil with 7 mm inner-groove tube, metered by an electronic expansion valve on R410A.
  • 1.3 L/h dehumidification: Condensate leaves through a 16 mm drain while the indoor fan steps between 350 and 540 m³/h, so humid nights stay comfortable.
  • 13,300 BTU of heating: Rated 3,900 W of heat for 1,130 W of input at a COP of 3.45/11.75, across the same -10 to 58 °C operating range.
  • Fed by the battery alone: A 48 V bank between 46 and 58 V DC is the whole electrical installation, so cooling continues overnight without mains or a generator.
  • 17,300 BTU off the battery: 5,070 W at T1 for 1,450 W of input, an EER of 3.50/11.80, with the compressor modulating from 4,100 up to 18,000 BTU.
  • COP of 3.75/12.80 in heating: The strongest heating efficiency in the DC48V line: 5,250 W of heat for 1,400 W drawn from the bank, or 18,000 BTU.
  • Twin-rotary Highly WHP05600: Two rotary stages on a variable-speed drive, a two-row coil in 9.52 mm inner-groove tube and an electronic expansion valve on R410A.
  • Four fan steps, 980 m³/h: A BLDC 45 W indoor fan gives four steps from 620 to 980 m³/h; the outdoor unit runs a BLDC 55 W motor at 880 rpm below 55 dB.
  • 22,000 BTU on battery power: The largest DC48V model still takes its entire supply from a 48 V bank between 46 and 58 V, with no AC connection in the installation.
  • Rated for 30-40 m²: 6,450 W of cooling at T1 for 1,840 W drawn, an EER of 3.50/11.85, modulating between 8,500 and 23,900 BTU as the room fills or empties.

Frequently Asked Questions

What does the DGA1-DC48V-12K connect to?

A 48 V battery bank, and nothing else. The supply window is 46 to 58 V DC, so the bank feeds the compressor without an inverter in the path.

What room size does the DGA1-DC48V-12K cover?

12 to 20 m². Below that the 9,000 BTU DGA1-DC48V-09K is the closer match; above 20 m² the 17,300 BTU DGA1-DC48V-18K takes the load.

How much battery current does it draw at part load?

Input power runs between 200 and 1,200 W in cooling, sitting at 980 W under T1 conditions and 1,090 W under T3. Sizing the bank around those figures is the usual practice.

Does it work in very hot weather?

It carries T1 and T3 climate ratings and an operating range of -10 to 58 °C. At T3 the unit gives 2,910 W, or 9,900 BTU, for 1,090 W of input, an EER of 2.65/9.05.

What are the pipe and wiring limits?

Refrigerant lines may run 15 m with an 8 m level difference, using 3/8 in gas and 1/4 in liquid pipe. Three metres of pipe and 4 m of connection wire ship with the unit.

How much battery power does the DGA1-DC48V-18K need?

In cooling it draws 220 to 1,780 W, sitting at 1,450 W under T1 and 1,660 W under T3, all of it from a 48 V bank held between 46 and 58 V DC.

What size room is the DGA1-DC48V-18K for?

20 to 30 m², which covers a living room or a two-bed room. Under 20 m² the 12,000 BTU DGA1-DC48V-12K is the closer fit, and above 30 m² the 22,000 BTU DGA1-DC48V-24K.

Why does this model heat better than the others?

Its rated heating COP is 3.75/12.80, the highest of the four, giving 5,250 W of heat for 1,400 W of input. Heating output spans 1,200 to 5,500 W.

What happens in T3 heat?

Output settles at 4,200 W, or 14,300 BTU, for 1,660 W of input, an EER of 2.55/8.60. The unit is rated for both T1 and T3 climates from -10 to 58 °C.

How far can the outdoor unit be placed?

Up to 20 m of refrigerant pipe with 10 m of level difference, on 1/2 in gas and 1/4 in liquid lines. Four metres of pipe and 5 m of wire are supplied, and the pair weighs 36 kg net.
