TSUN at Intersolar Europe 2025: Empowering Every Solar Scenario

This year at Intersolar Europe 2025 in Munich, TSUN proudly presented a comprehensive lineup of solar energy solutions designed to meet the diverse and evolving needs of homeowners, businesses, and solar professionals. From high-power microinverters to modular storage systems and solar kits, our innovations aim to make solar simpler, smarter, and more accessible. 

From Day 1, we welcomed a steady stream of visitors, including long-time partners, industry professionals, and curious new faces from across Europe and beyond. In total, we had over 5000 visitors on our booth and making connections. We hosted a dedicated product session introducing the MSU & MAU systems. Visitors were invited to explore our products hands-on, enter a lucky draw, and receive exclusive gifts. But more importantly, we had meaningful conversations that will drive new partnerships, new ideas, and new momentum for the industry.

Here’s a deep dive into the real-world applications of the products we showcased, and how TSUN is enabling more people to participate in the global transition to clean energy.

⚡TSUN Microinverter Series – Scalable Power from 300W to 6000W

From compact setups to complex systems, TSUN offers a complete portfolio of high-efficiency microinverters, including:

• in-1, 2-in-1, and 4-in-1 microinverters for small to mid-size rooftop systems
• MH2000 / MX3000D / MX3000D-T – dual or triple input options for more flexible design
• MP6000 – our flagship 3-phase inverter for commercial-scale applications

These microinverters ensure maximum energy harvest, module-level monitoring, and higher safety with no high-voltage DC lines. Installers benefit from faster setup and reduced complexity, while end users get reliable performance with real-time insights.

TSUN microinverters are compatible with virtually all module types and support parallel expansion, making them ideal for projects that need to scale over time.

🌞 ESK Balcony Air Vertical & ESK Pop-up

We also showcased the plug & play solar solution with solar panels, microinverters, brackets, and cables. They are pre-assembled, compact, and easy to deploy on balconies, rooftops, or small spaces. They are perfect for urban living – just set it up, plug it in, and start generating clean energy in minutes. Whether for homeowners or renters, the ESK makes solar truly accessible for everyone. Currently, we have stock in Europe. Arriving to your house at any time.

With 400W or 800W output, ultra-light panels, powerful and efficient microinverter, and app monitoring via Wi-Fi & Bluetooth, TSUN ESK Balcony Air Vertical is perfect for balconies and small spaces. It's easy to install, waterproof, and certified for safety – just plug it in and start generating clean energy.

SolarTrunk (MSU) & PowerTrunk (MAU)

This time, we also bring SolarTrunk MSU and PowerTrunk MAU – TSUN’s brand-new all-in-one balcony micro storage systems.

Both products have robust performance. Each unit offers 2kWh capacity and 2000W output power. The DE version adjusts output power to 800W to comply with government regulations. Both MSU and MAU have bidirectional charge and discharge. With high-rate LiFePO₄ battery cells, they support 1C charge and discharge. The difference lies in that PowerTrunk does not have solar input. It means that PowerTrunk is compatible with all households with or without solar systems installed. It can charge from grid when electricity price is low and discharge when it’s high. They’re stackable up to 10kWh, compact, easy to install, and designed for both on-grid and off-grid use.

SolarTrunk, the MSU, has maximum 4 MPPT input. Each MPPT is compatible with 700W+/18A solar panels, offering a maximum of 2800W input. It charges from solar panels and from grid, that said, it can take advantage of both solar energy and dynamic power tariff. Both products are all-in-one design with battery, built-in hybrid microinverter, and BMS. The Plug & Play design makes installation as simple as building blocks. No electrician is needed. Users can DIY them on balconies, gardens, garages, etc.

Users can achieve zero-export with TSUN Smart app and smart meter as they ensure real-time monitoring and dynamic output adjustments. Combined with bidirectional charge and discharge, SolarTrunk and PowerTrunk can take advantage of the dynamic tariff by charging at low rates and discharging at high rates.

Apart from daily energy storage, SolarTrunk and PowerTrunk can function as emergency power supply during outages or portable powerbank for outdoor use. They offer 2,000W AC output off-grid. They are both IP65 ingress protected and can operate from -20°C ~ +55°C with the self-heating function. During continuous overcast days, SolarTrunk and PowerTrunk can charge from grid to maintain a healthy battery SOC and extend longer lifecycle. SolarTrunk and PowerTrunk has 6000-cycle or 10-year warranty, giving you long-lasting security.

⚙️ACU – High-Capacity AC Coupled Storage

For users who need more power, the ACU delivers storage capacity ranging from 5kWh to 20kWh, designed to be installed alongside existing PV systems.

It’s ideal for retrofitting older solar setups or expanding energy autonomy for households and small commercial users. ACU allows users to take greater control of their consumption, shifting to self-consumption, load shifting, or backup power strategies.

With its robust build, smart control interface, and easy integration, ACU supports customers looking to go beyond basic energy savings and move toward true energy independence.

🌍 Looking Ahead

As solar adoption continues to grow globally, TSUN is committed to making solar energy simpler, smarter, and more user-friendly for everyone — from city apartments to countryside homes, and from individual users to professional installers.

We thank all our visitors, collaborators, and partners who joined us at Intersolar Europe 2025. We can’t wait to power the next chapter of solar together.
