TSUN Debuts Advanced Plug & Play Micro Storage Portfolio, Redefining Residential Solar Flexibility at Solar Solutions Dusseldorf

DUSSELDORF, Germany – December 4, 2024 – TSUN, a global innovator in solar and storage technology, is premiering its comprehensive new suite of balcony micro-storage solutions this week at Solar Solutions Dusseldorf (B12, Hall 14). The launch represents a strategic expansion of the company's Plug & Play ecosystem, addressing the growing European demand for scalable, retrofittable, and user-installable energy independence systems.

Moving beyond one-size-fits-all solutions, TSUN's latest offerings are engineered for specific application scenarios, providing both new and existing solar owners with precise tools to maximize self-consumption, optimize energy costs, and strengthen grid resilience.

Product Deep Dive: Engineered for Diverse Energy Needs

The showcased portfolio is built on a philosophy of modularity and intelligent energy management:

1. The Direct PV-Coupled Solution: SolarTrunk (MSU2000)

Designed as the optimal entry point for new balcony PV systems, this all-in-one unit integrates a 2kWh LFP battery, a 2000W bidirectional microinverter, and a BMS. It supports direct input from up to four solar panels (max. 2800W), converting and storing energy at the DC level for higher overall system efficiency. Its core innovation lies in eliminating complex system design, allowing true DIY installation from panel to socket.

2. The Retrofit & Grid Intelligence Solution: PowerTrunk (MAU2000)

Targeting the vast market of existing solar homes, the AC-coupled PowerTrunk connects seamlessly with all mainstream inverters. It intelligently captures excess AC power that would otherwise be exported, storing it for later use. Its advanced energy management system actively leverages dynamic electricity tariffs, automatically charging during off-peak periods and discharging during peak hours to deliver maximum financial savings without altering the primary solar setup.

3. The Future-Proof Hybrid Platform: MH2000 Microinverter

TSUN introduces a paradigm shift with the MH2000, a hybrid microinverter decoupled from a proprietary battery. This architecture grants users the freedom to select and upgrade battery brands, protecting their investment against battery technology obsolescence. The inverter itself boasts an extended lifecycle, reducing long-term maintenance costs and offering unparalleled flexibility in system design and battery capacity.

4. The Modular DC-Coupled Core: SolarCan (DCU2000Lite)

Showcased at the Innovation Boulevard, the SolarCan is a DC-coupled unit that acts as the intelligent core of a solar storage system. Installed between PV panels and microinverters, its stackable design allows flexible expansion from 2 to 10 kWh. It stores surplus DC energy for later use, featuring time-of-use control and zero export to maximize self-consumption and savings for households.

5. Scalable Plug & Play and Residential Solution: MAU5000 PowerTrunk Plus

Launching in early 2026, the MAU5000 PowerTrunk Plus is a 2.5 kW/5 kWh AC-coupled unit for Plug & Play or residential use. It features three smart modes: self-consumption, time-of-use, and dynamic tariff. It supports single- or three-phase grids, enabling businesses to cut peak-time energy costs and enhance power resilience efficiently.

6. Compact Innovation for Modern Living: MSU2000Lite

The 2026-bound MSU2000Lite is a compact evolution of the SolarTrunk. It utilizes space-saving 314 cells to achieve a smaller form. This all-in-one, Plug & Play unit for balconies offers full performance for urban homes where space and aesthetics are key priorities.

Leadership Commentary

"The European energy landscape requires not just products, but adaptable systems that grow with the homeowner," said Andy Liu, Founder and General Manager at TSUN. "Our new lineup directly answers this need. Whether it's a renter with a balcony system, a homeowner retrofitting storage, or someone designing a system from scratch, we now provide an optimized, professional-grade path that prioritizes longevity, financial payback, and effortless adoption."

Event Engagement

At the TSUN stand, engineering and sales teams are conducting detailed technical walkthroughs and live simulations of the energy management software. The focus is on demonstrating the tangible economic benefits and installation simplicity that underpin TSUN's value proposition to distributors, installers, and informed end-users.
