Deye heat pumps
Deye Monoblock R290 solar hybrid heat pumps (Hybrid ACDC). Heating, cooling and domestic hot water in one compact unit. Currently available in 12 and 16 kW.
What is the difference between ACDC and ACDC2?
For the 12–16 kW models, Deye offers two power supply versions — heating capacity, COP and dimensions are identical at the same rating; the versions differ in grid supply and DC input range.
ACDC
Single-phase grid supply (AC 220–240 V), DC PV input up to 410 V. Suitable for standard single-phase connections.
ACDC2
Three-phase grid supply (AC 380–415 V), wider DC PV input up to 660 V — suitable for longer panel strings.
The choice depends mainly on the type of grid connection of the building (single-phase vs. three-phase). Not sure which version suits your project better? Write to us at info@deyesolar.sk.
Buying guide
Deye solar hybrid heat pumps can be powered directly from PV panels as well as from the grid, and switch between sources automatically depending on solar availability. The range includes monobloc heat pumps for heating, cooling and domestic hot water (10, 12 and 16 kW) and pool heat pumps (11 and 17 kW).
R290 monobloc for family houses
The Deye Monoblock series uses the environmentally friendly R290 refrigerant with a GWP of 3 and achieves energy class A+++ at 35 °C and A++ at 55 °C. It can supply heating water at up to 80 °C, which makes it suitable for underfloor heating, radiators and fan coils. In summer it also provides cooling.
Heating capacity and efficiency at A7/W35: 10 kW with COP 4.7 (DAWG1-ACDC-10R3EP), 12 kW with COP 4.8 (DAWG1-ACDC-12R3EP and DAWG1-ACDC2-12R3EP) and 15 kW with COP 4.4 (DAWG1-ACDC2-16R3EP). Heating works at outdoor temperatures down to -25 °C.
How to choose between the ACDC and ACDC2 versions
The ACDC version has a single-phase grid supply and a DC input from the panels of up to 410 V. The ACDC2 version has a three-phase supply and a wider DC input of up to 660 V, suitable for longer panel strings. For the same capacity, the thermal parameters and dimensions are identical — the deciding factor is mainly the type of electrical connection.
Pool heat pumps
Deye DSPD1 pool heat pumps with R32 refrigerant have a titanium heat exchanger resistant to chlorinated water and an IPX4 rating for outdoor installation. The 11 kW model suits pools of up to 50 m³, the 17 kW model pools of up to 65 m³. Like the monoblocs, they can be powered from solar panels as well as from the grid.
What is not included in the delivery
The hot water cylinder, buffer tank and heat emitters are not included in the delivery of the heat pump — they are ordered separately according to the heating design.
Frequently asked questions
How does a solar hybrid heat pump work?
The heat pump has a DC input to which the PV panels are connected directly. When the sun is shining, it runs primarily on solar energy, otherwise from the grid — it switches automatically depending on solar availability.
What heat pump capacity do I need?
The capacity is determined by the heat loss of the house, which is calculated by a heating designer. The 16 kW model is intended for larger houses with higher heat loss.
Which refrigerant do the heat pumps use?
The monoblocs for heating use the natural refrigerant R290 (GWP 3), the pool heat pumps use R32.
Is a hot water cylinder included in the delivery?
No. The hot water cylinder, buffer tank and heat emitters are ordered separately.
