DC48V Solar Air Conditioner – 9,000 BTU

DC48V Solar Air Conditioner – 9,000 BTU | 100% Off-Grid

Stay cool without the grid. The DC48V Solar Air Conditioner is built for homes, cabins, workshops, and remote sites where mains power is unreliable, expensive, or simply unavailable. Running directly from a 48V DC battery bank charged by solar, it delivers 9,000 BTU of cooling power while keeping your energy costs and grid dependence at zero.

Because it runs natively on DC power, there’s no need for a power-hungry inverter to convert battery power to AC. That means less energy wasted in conversion and more of your stored solar power going straight into cooling. Built-in battery low-voltage protection automatically safeguards your battery bank from deep discharge, helping protect your investment and extend battery life.

Designed to perform in demanding climates, this unit operates across a wide temperature range from -10°C up to a scorching 58°C, so it keeps working reliably when you need it most.

Key Features

• 100% Off-Grid Operation: Runs entirely on solar-charged battery power, with no reliance on mains electricity.
• DC 48V Battery Powered: Connects directly to a standard 48V battery bank, a common voltage for residential and off-grid solar systems.
• Battery Low-Voltage Protection: Automatically protects your batteries from damaging over-discharge.
• DC-Driven High Efficiency: Native DC operation avoids inverter conversion losses so more of your stored energy goes into cooling.
• Wide Operating Temperature: Performs from -10°C to 58°C, ideal for hot climates and harsh environments.
• 9,000 BTU Cooling Capacity: Well suited to bedrooms, home offices, cabins, site offices, and other small-to-medium spaces.

Ideal For

Off-grid homes and cabins, remote site offices, farms and agricultural buildings, telecom and equipment shelters, workshops, and anyone looking to cut electricity bills with solar-powered cooling.

Frequently Asked Questions

Does this air conditioner need grid electricity to run?
No. It’s designed for 100% off-grid use and runs entirely from a 48V DC battery bank, which can be charged by solar panels.

Can I connect it directly to solar panels?
The unit is powered by a 48V battery bank. Solar panels charge the batteries through a solar charge controller, and the air conditioner draws its power from the batteries. This setup allows it to keep running after sunset and during cloudy periods.

Do I need an inverter?
No. Because it’s DC-driven, it connects directly to your 48V battery system without an inverter, avoiding the energy losses that come with DC-to-AC conversion.

What does battery low-voltage protection do?
It monitors your battery voltage and shuts the unit down before the batteries are drained to a damaging level. This helps prevent deep discharge and extends the life of your battery bank.

Will it work in very hot weather?
Yes. It’s rated to operate in ambient temperatures from -10°C up to 58°C, making it suitable for extreme hot-climate conditions.

What size room can a 9,000 BTU unit cool?
A 9,000 BTU air conditioner is typically suited to small-to-medium spaces such as bedrooms, offices, and cabins. Actual performance depends on room insulation, sun exposure, ceiling height, and local climate.

Is it compatible with my existing solar system?
If your solar system uses a 48V battery bank, it’s designed to integrate with it. For systems running at 12V or 24V, a 48V battery configuration would be required.

How long will it run on my batteries?
Run time depends on your battery bank capacity, solar array size, cooling settings, and outside temperature. A larger battery bank and solar array will support longer running hours, including overnight use.
