TSUN Launches Revolutionary Micro Storage Systems for Solar Energy Solutions

TSUN Unveils Innovative All-in-One Solar Storage Solutions

April 23, 2025, Suzhou, China – TSUNESS (TSUN), a prominent global player in smart energy solutions, has made headlines with the introduction of its latest products, the SolarTrunk and PowerTrunk micro storage systems, complemented by the powerful MX3000D micro inverter. These advancements mark a significant leap in the realm of solar energy for residential use.

Founded in 2019, TSUN draws from over 15 years of expert knowledge among its core team members. The new product launch on March 25 captured attention across Europe, with SolarTrunk and PowerTrunk being unveiled in Germany, while the MX3000D debuted in France. Such developments reflect TSUN’s commitment to empowering households and businesses by enabling energy independence.

All-in-One Micro Storage Systems

The SolarTrunk and PowerTrunk are pioneering solutions designed for balcony and garden usage. These innovative systems utilize sustainable energy and offer significant reductions in household electricity bills. With advanced bidirectional charging and discharging capabilities, users can leverage dynamic tariffs or time-based electricity pricing. The SolarTrunk model boasts a remarkable 4 MPPT (Maximum Power Point Tracking) input capacity of 2800W, ensuring efficient energy usage.

One of the standout features of these products is their integrated design, which combines a battery, hybrid micro inverter, and Battery Management System (BMS) into one unit. This functionality streamlines installation, making it as easy as a DIY project. With no need for a professional electrician, users can conveniently set up the systems on balconies, gardens, garages, and more.

Moreover, the performance of SolarTrunk and PowerTrunk is impressive, incorporating high-rate LiFePO4 battery elements. They can handle charging and discharging rates of 1C, offering a capacity of 2 kWh per unit that can be stacked to achieve up to 10 kWh, allowing users to customize their energy storage solutions adequately.

With TSUN’s smart application and intelligent meter, users can fine-tune their energy export levels to reach zero export, facilitating real-time monitoring and dynamic adjustments in energy generation.

Besides serving daily energy storage needs, these systems double as backup power sources during outages and can function as portable energy banks for outdoor activities. They deliver a robust AC output of 2000W along with two Type-C and USB ports. Designed to withstand harsh elements, they come with an IP65 protection rating, functioning seamlessly even in temperatures ranging from -20°C to +55°C.

The MX3000D Micro Inverter

Highlighting the potential of residential solar energy systems, the MX3000D micro inverter stands out with its high performance, scalability, and enhanced safety features. It can accommodate power levels up to 3300W, connecting with six high-capacity solar panels (700W or more). Diverse wiring options are available, including balcony, Daisy Chain (VDE EMC certified), and Trunk Cable configurations, ensuring rapid plug-and-play installation.

The MX3000D's Daisy Chain and Trunk setups allow users to easily expand their systems from 3000W to 9000W, providing flexibility as energy needs evolve. Importantly, unlike traditional string inverters, this micro inverter operates at a safe low voltage (≤60V), eliminating the necessity for additional safety components, such as RSD, AFCI, or DC boxes.

To facilitate seamless system monitoring, the MX3000D includes an integrated RS485 interface as well as Wi-Fi connectivity, with optional 4G support for stable performance, even in areas with limited internet access.

Conclusion

The unveiling of the SolarTrunk and PowerTrunk micro storage systems, alongside the MX3000D inverter, sets a new benchmark in solar energy solutions at TSUN. As these products roll out their impressive capabilities, TSUN ensures the accessibility and practicality of solar energy usage for the everyday user. With a focus on innovation and customer ease, TSUN is well-poised to lead the future of sustainable energy solutions across more than 50 countries worldwide.
