Description

The Deye DWGA21-ACDCBLW-12KR2(EU) is a 3.5kW hybrid AC/DC solar-assisted wall-mounted split air conditioner for cooling and heating. It uses compatible solar PV power during the day and automatically keeps standard AC grid power available as backup when sunlight is not sufficient.
With integrated solar MPPT, full DC inverter technology, WiFi smart control and R32 refrigerant, this model is suitable for homes, offices and small commercial spaces looking for comfortable indoor climate with smarter daytime energy use.
Key Benefits
Solar-assisted cooling and heating
Use available solar energy during the day to support cooling or heating operation.
Hybrid AC/DC operation
The unit can work with compatible DC solar input and standard AC grid power. No battery is required for hybrid operation.
Integrated solar MPPT booster
The solar MPPT system is built into the outdoor unit, helping the air conditioner make better use of PV input.
Comfort in summer and cooler seasons
The 12000BTU / 3.5kW class model provides both cooling and heating performance for everyday comfort.
Full DC inverter technology
Efficient inverter operation helps the unit adjust output according to room demand.
WiFi smart control
Control temperature, operating mode and schedules conveniently via app, depending on local setup and compatible control options.
R32 refrigerant
Uses R32 refrigerant, commonly used in modern air-conditioning systems.
Multiple protection features
Includes multiple protection functions and compressor delayed restart protection.
Detailed Description
The Deye DWGA21-ACDCBLW-12KR2(EU) is designed for users who want to combine everyday air-conditioning comfort with direct daytime solar energy use. It is a wall-mounted split air conditioner with one indoor unit and one outdoor unit, suitable for cooling and heating applications.
During sunny hours, compatible PV modules can provide DC power directly to support the air conditioner. If solar energy is not enough, standard AC grid power remains available as backup. This makes the system especially interesting for buildings with available roof or balcony PV space, where daytime cooling demand often matches solar generation.
Unlike conventional systems that require a separate solar inverter or battery storage, the Deye hybrid AC/DC design integrates the solar MPPT booster and inverter into the outdoor unit. This helps simplify the solar-assisted operation while maintaining flexible grid backup.
The 12000BTU / 3.5kW class model is listed with 3500W cooling capacity and 3500W heating capacity. It also features full DC inverter technology, smart display, WiFi smart control, multiple protection and compressor delayed restart protection.
For correct installation, refrigerant handling and electrical connection, this product must be installed and commissioned by a qualified air-conditioning professional.
PV Connection Information
For solar-assisted operation, the air conditioner can be connected to compatible photovoltaic modules within the required DC input voltage range.
A practical PV design often uses several standard solar modules connected in series to reach the required operating voltage. For example, modules with an open-circuit voltage of around 38–42V may be combined in series, depending on module type, temperature conditions, installation location and local design requirements.
The final PV design must always be checked by a qualified installer to ensure correct voltage range, cable sizing, protection devices and compliance with local regulations.
