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.

Once the room reaches 20 to 30 m², a single rotary compressor is no longer enough, and the DGA1-DC48V-18K answers with a twin-rotary Highly WHP05600 running on a two-row coil of 9.52 mm inner-groove tube. Power still comes from the 48 V bank alone, anywhere between 46 and 58 V DC, so a living room can be held cool overnight without starting a generator. Cooling is 5,070 W at T1 for 1,450 W of input, an EER of 3.50/11.80, spanning 4,100 to 18,000 BTU as the load moves. T3 conditions leave 14,300 BTU on the table. Heating is where this model stands apart: 18,000 BTU for 1,400 W of input, a COP of 3.75/12.80, the best in the DC48V range. The indoor unit moves up to 980 m³/h under 46 dB, removes 1.7 L/h of moisture, and the outdoor unit can sit 20 m away. We are an authorised Deye distributor and supply the DGA1-DC48V-18K from our own stock, with technical support before and after the sale.

Every capacity the Deye battery records state: 20, 39, 40, 100, 120, 200, 208, 235, 280 and 314 Ah, 1.28 to 4340 kWh — and how your own figure gets built.
Read: Deye Battery Capacities in Saudi Arabia: 20 Ah to 314 Ah →We list 134 solar inverters, each with a published spec record, from 300 W to 136 kW. Five rows separate them: phase, battery, efficiency, derating and noise.
Read: The Deye Inverter Range, Row by Row: What Separates the Models →Programming a Deye is not a list of steps, it is a set of limits the record states. Of 134 inverter records, 52 accept a battery and 49 of those state six programmable charge/discharge periods. Here are the figures.
