48V DC Solar Air Conditioner with 110V/220V AC Grid Backup and Solar Panels

Hybrid Solar Air Conditioning for Reliable and Energy-Efficient Cooling

The 48V DC Solar Air Conditioner combines solar power with 110V or 220V utility electricity to provide stable, energy-efficient cooling for residential, commercial and off-grid applications.

During periods of strong sunlight, the system prioritizes available solar energy to reduce grid electricity consumption. When solar power is insufficient, the air conditioner can use utility power to maintain continuous operation and a comfortable indoor temperature.

With solar panels, intelligent energy management and flexible AC/DC power options, this system is suitable for locations with high electricity costs, unstable grid supply or abundant solar resources.

Key Features

Hybrid AC/DC Power Operation

The system can operate using available solar DC power and utility AC power.

Depending on the selected model and system configuration, it may support:

• 48V DC solar or battery input
• 110V AC grid input
• 220V AC grid input
• Automatic solar and grid power management
• Hybrid operation for continuous cooling

Please confirm the required voltage and frequency before ordering.

Solar-Powered Daytime Cooling

Solar panels generate electricity during daylight hours to support air-conditioner operation.

Because cooling demand is often highest when solar irradiation is strongest, the system can effectively use daytime solar energy and reduce dependence on utility electricity.

Automatic Grid Backup

When sunlight decreases or the cooling load exceeds the available solar power, utility electricity can automatically provide additional energy.

This allows the air conditioner to continue operating during:

• Cloudy weather
• Early morning or evening hours
• Periods of high cooling demand
• Insufficient solar panel output

High-Efficiency Inverter Technology

The inverter compressor adjusts its operating speed according to the indoor temperature and cooling demand.

This helps provide:

• Stable indoor temperatures
• Lower unnecessary energy consumption
• Reduced compressor starts and stops
• Quieter operation
• Improved operating efficiency
• Greater indoor comfort

Optional Battery Compatibility

Selected system configurations may support connection to a compatible 48V battery bank for operation when solar and grid power are unavailable.

Battery compatibility, charging requirements and backup duration depend on the selected model, battery type and system configuration.

Intelligent Energy Management

The built-in controller manages available solar, battery and grid power automatically.

The system adjusts its energy source according to:

• Solar panel output
• Cooling demand
• Grid availability
• Battery status, where applicable
• Selected operating mode

This reduces the need for manual switching during normal operation.

Reliable Cooling Performance

The system is designed to provide dependable cooling for homes, offices, shops and remote facilities.

Available cooling capacities may vary by model. The correct capacity should be selected according to room size, insulation, local climate and expected operating conditions.

Modern Split-System Design

The wall-mounted indoor unit offers a clean, modern appearance suitable for a wide range of interiors.

The outdoor unit, solar panels and optional power-control equipment can be configured according to the installation environment and project requirements.

Comprehensive Protection

Available safety and protection functions may include:

• Overvoltage protection
• Undervoltage protection
• Overcurrent protection
• Overload protection
• Overtemperature protection
• Compressor protection
• Short-circuit protection
• Automatic fault detection
• Automatic recovery

Protection functions vary according to the selected model.

How the System Works

During the daytime, the solar panels generate DC electricity to support the air conditioner.

When sufficient solar energy is available, the system reduces the amount of electricity required from the utility grid. If solar output decreases, grid power automatically supplements the available solar energy to maintain stable cooling.

In configurations equipped with compatible battery storage, excess solar energy may be stored for later use. The exact operating sequence depends on the selected controller, battery and air-conditioner model.

Solar Panel Configuration

The required number and capacity of solar panels depend on:

• Air-conditioner cooling capacity
• Rated input power
• Local solar irradiation
• Daily operating time
• Installation angle
• Roof or ground installation space
• Whether battery storage is included
• Required solar contribution

Our technical team can recommend a suitable solar panel configuration according to the installation conditions.
