Introducing the Sunsynk Acure: Our Next Generation Hybrid Inverter

As solar energy adoption continues to grow, so does the demand for smarter, safer, and more future-ready solutions. At the core of every installation is the inverter, the critical piece of technology responsible for transforming solar energy into usable electricity. Whether you’re powering a home, managing a business, or building an off-grid setup, the quality of your inverter directly impacts the reliability and efficiency of the entire system.

The launch of Sunsynk’s Acure Series represents the next generation of hybrid inverter technology. Designed from the ground up with both installers and system owners in mind, Acure goes beyond small improvements. It is a complete reimagining of what a modern hybrid inverter can and should be.

Understanding Hybrid Inverters

A hybrid inverter combines the capabilities of a traditional solar inverter and a battery inverter in a single product. Like any inverter, it converts DC power from solar panels into AC power for use in your home or business. But hybrid inverters go further: they also manage battery storage, allowing you to store excess solar energy for use at night, during load shedding, or when grid power is unavailable.

Unlike older systems that required separate inverters for solar and batteries, a hybrid inverter is more efficient, cost-effective, and easier to install. It can seamlessly switch between solar, battery, and grid power depending on demand, automatically optimising usage for maximum savings and self-sufficiency. Many hybrids, including Acure, also support grid export, smart load control, and off-grid backup capabilities.

Built To Perform

The Sunsynk Acure is our most advanced hybrid inverter to date, combining high-efficiency energy conversion with integrated connectivity and intuitive control. Every feature has been engineered to reduce complexity, save installation time, and provide long-term value.

Available in single-phase 3.6-8kW and three-phase 5-12kW models*, the Acure range is suitable for everything from smaller homes to large commercial installations. Whether you’re starting fresh or upgrading an existing system, Acure adapts effortlessly to your needs.

Connectivity comes standard with Bluetooth, Wi-Fi, Ethernet (LAN), and LoRa all built in. That means faster setup and reliable remote monitoring straight out of the box, without the need for external modules or dongles.

What Makes the Acure Different?

The Acure isn’t just another hybrid inverter; it’s designed to deliver faster installations, smarter control, and safer operation.

A wireless CT coil and support for up to ten wireless smart switches reduce unnecessary cabling while enabling dynamic load management. A hinged terminal cover and discreet cable routing give every installation a cleaner, more professional finish, while also enhancing safety.

Built-in arc fault detection reduces the risk of electrical fires, while a PV circuit alarm alerts users if panels are tampered with, disconnected, or stolen. The Acure also supports rapid shutdown and dry contact generator start, providing flexible backup options for grid failures or off-grid use. Combined with its IP65 weatherproof rating, the Acure is engineered for both indoor and outdoor installations, offering robust protection in any environment.

Total Control with Sunsynk Connect Pro

Pair Acure with Sunsynk Connect Pro, our cloud-based energy management platform, for complete visibility and control. Through the mobile app, users can track generation, consumption, and battery status in real time, all within a clear, intuitive interface. Installers benefit from remote commissioning, adjustments, and troubleshooting, reducing site visits and downtime, while commercial operators gain fleet management tools including multi-site monitoring, user permissions, and remote firmware updates.

To get deeper insight into the thinking behind the Acure, we sat down Sunsynk UK Managing Director Steve Donaldson. Here, he shares why the Acure range was developed and what it means for both installers and homeowners. 

Q: Steve, what prompted Sunsynk to develop this new range alongside your existing successful inverter products? 

The Acure really represents our philosophy of "respecting the past whilst designing for the future." Our existing range has been incredibly successful globally and continues to serve our customers brilliantly. But we recognised there was an opportunity to address some specific challenges that installers face, particularly around complex cabling and monitoring setup. The Acure builds on everything we've learned from our proven technology whilst introducing innovations like wireless CT coil technology that genuinely solve real-world problems. It's about giving installers choice - they can continue with our established range or opt for Acure when projects would benefit from wireless capabilities. 

Q: The wireless CT coil technology is being positioned as a key differentiator. Why is this feature so significant for installers? 

Wireless CT technology transforms the installation experience in properties where running cables is challenging or disruptive. Think about Victorian terraces, listed buildings, or homes where customers simply don't want cable runs through finished surfaces. With LoRa technology providing reliable communication over several hundred metres, installers can position monitoring points optimally without compromising on aesthetics or spending hours planning cable routes. It's particularly valuable in retrofit situations where traditional wired solutions might require significant disruption. The feedback we've had so far is that it opens up opportunities for projects that installers might previously have declined due to cabling complexity. 

Q: What specific features of the Acure are you most excited about from a business perspective? 

The integration capabilities really excite me. The Acure supports up to 10 wireless smart switches, which means installers can offer comprehensive energy management solutions rather than just solar equipment. This creates ongoing service opportunities - managing water heaters, pool pumps, EV chargers, and air conditioning through intelligent scheduling. It's about positioning installers as energy consultants rather than just equipment suppliers, which naturally leads to stronger customer relationships.  

Q: Safety features like arc fault detection and solar panel theft detection are built into the Acure rather than offered as optional extras. What's the thinking behind this approach? 

Safety simply cannot be optional. By integrating arc fault detection directly into the inverter, we ensure every installation has this crucial protection without relying on installers to remember additional components or customers to approve extra costs. We've seen too many situations where optional safety devices either weren't installed or failed to operate correctly. Solar panel theft detection addresses a growing concern, particularly as solar installations become more common and therefore more attractive to thieves. When safety features are built-in, there's no question about whether they're present and functioning correctly, which protects both the customer's investment and the installer's reputation. 

Why the Acure, and Why Now?

As energy prices continue to rise and grid reliability becomes increasingly uncertain, having a smart, resilient energy system is no longer a luxury - it’s a necessity. The Acure provides a future-proof platform that delivers efficiency, safety, and adaptability in equal measure. Whether you’re installing your first solar system or scaling a commercial operation, Acure  gives you the confidence to grow, adapt, and optimise.
