Suncool Retrofit Coldrooms
Retrofit Existing Coldrooms with Solar and Battery
Turn your existing coldroom into reliable off grid cold storage
If you already have an insulated coldroom, we can design and install a solar + battery system with a 24‑volt DC refrigeration package with integrated backup power. The result is a quieter, cleaner operation, and far less generator runtime or expense from grid-fed electricity bills.
How Plug-In Coldrooms Works
How It Works
Reliable off-grid cooling, powered by the sun.
Suncool Coldrooms use solar panels to charge an onboard battery system, which powers a 24V DC compressor to keep your goods at a steady 2°C — even when you’re far from the grid.
Solar Panels
Capture energy from the sun to power the system
Battery Bank
Stores solar power to keep the coldroom running day and night
24V DC Compressor
Reliable and consistent cooling down to 2°C
Controller
Simple digital controls to set and monitor the temperature
Backup System
Ensures reliability when solar power is limited
Green energy
Runs on solar to lower the environmental impact
Off-grid Ready
Operates anywhere without mains power
Portable
Perfect for markets, farms, and remote sites
Quiet and Cost Saving
No noisy engines or ongoing diesel costs
Retrofit Existing Coldrooms with Solar + Battery
Already have a coldroom or insulated container? We can retrofit it with solar + battery power to lower your energy costs and reduce reliance on diesel generators.
We’ve worked with infrastructure, mining, food processing and farming operations to help them achieve energy-efficient refrigeration in even the most remote conditions.
Designed for Your Room, Your Site
Every retrofit system is engineered specifically for your coldroom and your location.
We assess your refrigeration needs and solar exposure, then design a system with the right combination of compressor, battery, and solar panels to keep you reliably cool – day and night.
Turn On & Cool
Once your system is installed, you simply turn it on and it runs.
The system is quiet, low-maintenance, and works even when there’s no sunshine thanks to the battery backup.
You can also monitor performance and temperature via digital display.
Where It Works
Remote farms, food processors, and disaster response agencies are all using our retrofit solar + battery systems to bring energy‑efficient cooling to insulated rooms in the field.
These systems are especially useful in regions with limited generator fuel or no grid access.
A Smarter Way to Power Your Coldroom
Retrofitting solar + battery power to your existing coldroom is one of the most effective ways to reduce operational costs – especially in off-grid or remote settings. Whether you’re running a farm, a mining site, or a disaster response unit, our customised systems are designed to meet your cooling needs without the hassle of diesel or connection to mains power.
Our team handles every step, from site assessment and custom design to installation and aftercare. We engineer systems that are durable, high-performing, and tailored to Australia’s unique environmental conditions.
With Suncool Coldrooms’ retrofit solutions, you’re not just upgrading your power supply – you’re investing in long-term reliability, sustainability, and savings.

Frequently Asked Questions
What is a solar + battery retrofit system?
A solar + battery retrofit system is a customised upgrade that allows existing coldrooms or refrigeration units to run on solar power. It combines photovoltaic panels with battery storage to provide reliable off-grid cooling — without needing diesel or mains electricity.
Can any coldroom be retrofitted with solar power?
Most standard coldrooms can be adapted with the right assessment and design. Our team evaluates your unit’s size, power draw, and operational use to determine the best-fit solar + battery configuration for your site.
What are the main benefits of retrofitting with solar?
Retrofitting helps you reduce energy costs, cut carbon emissions, and operate independently of fuel supply or power outages. It’s ideal for remote, mobile, or seasonal operations that need consistent refrigeration without relying on grid access.
How long does the retrofit process take?
Timeframes vary depending on the system and location, but most retrofits are completed within a few days to a week. Our team handles everything – from solar panel fitting to system integration and testing.
Will solar power be enough to keep my coldroom running 24/7?
Yes. Our retrofit systems are designed to store energy efficiently in lithium battery banks, ensuring stable temperature control through night hours, cloudy conditions, or low-sun periods.
What if I still need backup power?
We offer hybrid options that include optional backup generators or can be integrated with grid power if needed, giving you total flexibility for your operation.
