Product Details

Energy-Efficient Solar Cooling for Homes and Off-Grid Applications

The SOONEST DC Solar Air Conditioner System uses electricity generated by solar panels to provide efficient and reliable indoor cooling.

The complete solution can include solar panels, an indoor air-conditioning unit, an outdoor compressor unit, a solar controller or inverter, connecting cables and an optional battery system. It is suitable for homes, offices, shops, farms and remote buildings where grid electricity is expensive, unstable or unavailable.

By using solar power during the daytime, the system can reduce dependence on utility electricity and lower daily operating costs.

Key Features

Direct Solar Power Operation

The air conditioner can use DC electricity generated by compatible solar panels.

During periods of strong sunlight, solar energy can support or operate the cooling system, helping reduce electricity consumption from the utility grid.

Actual solar contribution depends on:

  • Solar panel capacity
  • Local sunlight conditions
  • Air-conditioner power consumption
  • Indoor cooling demand
  • Ambient temperature
  • System configuration

Complete Solar Air-Conditioning Solution

A complete system may include:

  • Indoor air-conditioning unit
  • Outdoor compressor unit
  • Solar panels
  • Solar controller
  • DC power-management equipment
  • PV connection cables
  • Optional battery storage
  • Optional grid backup equipment

The exact components included should be confirmed before ordering.

High-Efficiency Inverter Compressor

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

This helps provide:

  • Stable indoor temperatures
  • Reduced compressor starts and stops
  • Lower unnecessary energy consumption
  • Smooth and quiet operation
  • Improved indoor comfort

Optional Battery Backup

A compatible battery system can store excess solar energy for use when sunlight is insufficient.

Battery storage may support operation during:

  • Cloudy weather
  • Evening hours
  • Temporary power outages
  • Periods of low solar generation

Battery compatibility, voltage and required capacity depend on the selected air-conditioner model and system design.

Optional Grid Backup

Selected configurations may support utility-grid backup.

When solar power is insufficient, grid electricity can provide additional energy to maintain continuous cooling. This hybrid configuration combines the energy-saving benefits of solar power with the reliability of conventional electricity.

Intelligent Energy Management

The controller automatically manages available solar, battery and grid energy according to the system configuration.

It can adjust the power source based on:

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

This reduces the need for manual switching during normal operation.

Reliable Cooling Performance

The system is designed to provide dependable indoor cooling for residential and light commercial spaces.

Available cooling capacities vary by model. The correct air conditioner should be selected according to:

  • Room size
  • Ceiling height
  • Building insulation
  • Local climate
  • Number of occupants
  • Heat-producing equipment
  • Daily operating time

Modern Split-System Design

The wall-mounted indoor unit features a clean and modern appearance suitable for homes, offices, stores and accommodation facilities.

The outdoor unit can be installed in a ventilated location, while the solar panels may be mounted on a roof, frame or suitable open area.

Smart Control Functions

Depending on the selected model, available functions may include:

  • Adjustable cooling temperature
  • Multiple fan-speed settings
  • Sleep mode
  • Timer function
  • Automatic restart
  • Remote control
  • LED display
  • Fault-code display
  • Optional Wi-Fi monitoring

Functions vary by model.

Comprehensive Protection

Available protection functions may include:

  • DC overvoltage protection
  • DC undervoltage protection
  • Overcurrent protection
  • Overload protection
  • Short-circuit protection
  • Compressor protection
  • Overtemperature protection
  • Reverse-polarity protection
  • Automatic fault detection
  • Automatic recovery

Protection functions depend on the selected configuration.

Main Benefits

  • Uses renewable solar energy for cooling
  • Reduces dependence on utility electricity
  • Suitable for off-grid and hybrid applications
  • High-efficiency inverter compressor
  • Optional battery storage
  • Optional grid backup
  • Intelligent energy management
  • Stable and comfortable indoor cooling
  • Suitable for areas with strong sunlight
  • Flexible solar panel configuration
  • Modern wall-mounted design
  • Suitable for residential and commercial use

Typical Applications

The DC solar air conditioner is suitable for:

  • Residential homes
  • Apartments and villas
  • Offices
  • Retail stores
  • Hotels and guesthouses
  • Restaurants and cafés
  • Farms and rural properties
  • Remote cabins
  • Construction-site offices
  • Guard rooms
  • Schools and classrooms
  • Clinics
  • Telecom equipment rooms
  • Areas with unstable electricity
  • Off-grid solar power systems
  • Regions with high electricity costs

How the System Works

Solar panels convert sunlight into DC electricity.

The controller regulates the generated power and supplies energy to the air-conditioning system. During periods of sufficient sunlight, solar power can operate the air conditioner and may also charge a compatible battery.

When solar generation decreases, the system may use stored battery energy or utility electricity, depending on the selected configuration.

The intelligent controller coordinates the available power sources to maintain stable cooling performance.

Solar Panel Configuration

The required solar panel capacity depends on:

  • Air-conditioner cooling capacity
  • Rated input power
  • Local solar irradiation
  • Daily operating hours
  • Installation angle
  • Shading conditions
  • Required solar contribution
  • Battery-storage requirement

A larger solar array may provide a higher solar contribution and reduce grid electricity consumption.

Product Selection Guide

Please provide the following information before ordering:

  • Room size
  • Required cooling capacity
  • Local ambient temperature
  • Daily operating hours
  • Available solar-panel installation space
  • Average local sunlight
  • Required DC system voltage
  • Battery requirement
  • Required backup duration
  • Grid availability
  • Local grid voltage and frequency
  • Off-grid or hybrid application

Our technical team can recommend a suitable air conditioner, solar panel capacity, controller and optional battery configuration.

Important Notes

  • Confirm the required DC input voltage before ordering.
  • Solar panels must match the controller and air-conditioner specifications.
  • Battery voltage and capacity must be compatible with the system.
  • The number of solar panels depends on the selected cooling capacity and local sunlight.
  • Allow sufficient ventilation around the outdoor unit.
  • Installation should be completed by qualified HVAC and solar technicians.
  • Product appearance, components and functions may vary by model.
