products DESCRIPTIONPRODUCTS
The Deye DC 48V Solar Air Conditioner is a wall-mounted, 100% off-grid cooling and heating system designed for locations without reliable grid access. It operates directly on a 48V battery bank charged by solar panels, eliminating the need for an inverter and reducing energy conversion losses.
1. Core Features
100% Off-Grid Operation: Runs entirely on DC 48V power (operating range 46–58V) from a battery bank, with no grid connection required.
High-Efficiency DC Compressor: Features a brushless DC compressor (rotary variable-speed) that operates directly on solar power, bypassing AC conversion losses for maximum efficiency.
Wide Operating Temperature: Engineered to function reliably in extreme ambient temperatures ranging from -10°C to 58°C, suitable for tropical and harsh environments.
Integrated Battery Protection: Includes low-voltage protection that triggers a safe shutdown to prevent deep discharge and damage to the battery bank.
Smart Control & Monitoring: Wi-Fi enabled for remote monitoring and control via a smartphone app, with programmable settings for convenience and performance optimization.
2. Key Advantages
Significant Cost Savings: Eliminates reliance on grid electricity or diesel generators, substantially reducing long-term energy costs in remote locations.
Higher Energy Efficiency: By running DC power directly to the compressor, it avoids the efficiency losses inherent in converting DC solar power to AC. Models like the 12K unit achieve an EER of 3.60 at T1 conditions.
Reliable for Remote Locations: Specifically designed for telecom stations, container houses, and other off-grid sites where stable power is scarce. It provides dependable climate control with minimal maintenance.
Precise Temperature Control: The variable-speed inverter compressor allows for precise temperature regulation and quieter operation, while only drawing the power needed to maintain the setpoint.
3. FAQs
1. What is the power source for this air conditioner?
It operates 100% off-grid using a DC 48V battery bank (typically LiFePO4 or lead-acid) charged by solar panels. It does not connect to the grid and does not require an AC inverter for operation.
2. How large of a solar system is needed to run this AC?
For a 12,000 BTU (1 Ton) model, a general rule of thumb is that it requires around 1.5 to 2 kW of solar power to charge the battery bank adequately. The exact size depends on your location's solar irradiance and daily usage, so consulting a solar professional for sizing is recommended.
3. Is this unit compatible with standard solar panels and batteries?
Yes. It is designed to work with standard solar PV panels via a charge controller. It is compatible with any 48V battery bank operating within the 46–58V DC range, including both LiFePO4 and lead-acid types.
