Sunpura at Düsseldorf – Three Years On｜From “Showing Up” to “Leading the Way,” We Use Long-Termism to Brighten the Future of Home Energy
In December, the winter light glimmers across Messe Düsseldorf, and at booth HALL14-G1, the SUNPURA logo stands out vividly in the crowd. This is our third consecutive year here — the nerves of our debut three years ago, last year’s energetic exchanges with customers, and the calm confidence we brought this year with new products and deep industry conversations… all come together as one simple truth:
One steady step at a time — real progress, year after year.
Three Years in Düsseldorf: From Newcomer to Trusted Companion
2023. We entered the “plug-and-play storage” field as the new face. The booth still had the simplicity of a first-timer — a silver-white home storage system and the first-generation NOVB2048 plug-and-play unit (non-stackable) quietly on display. We demonstrated every function live, answering each question with sincere, straightforward honesty.
2024. We returned with the upgraded, stackable Sunpura S2400 plug-and-play storage system. Europe’s home-energy transition was accelerating, and customer questions had shifted from “Does it work?” to “How can it work even better?”
So we built a Smart Energy Ecosystem Zone, recreating a real household setup connecting storage devices, smart meters, and dynamic-pricing systems. Visitors could use the Sunpura App directly and feel what energy autonomy truly means. By the end of the show, we had gained cooperation intentions from 50+ European distributors.
2025. Standing again at HALL14-G1, we understood long-termism on a deeper level. It’s not about showing up every year — it’s about showing up with better, more user-centered products, a more open ecosystem, and more solid technology, growing together with the industry.
Düsseldorf 2025: We Launch the “Future-Grade” S2400 Pro
This year, our main spotlight was the S2400 Pro — the world’s first 5G/2.4G dual-band smart energy-storage system. From S2400 to S2400 Pro, this wasn’t a minor tweak — it was a major upgrade built to solve real market pain points:
-
More Stable Communication — World’s First 5G/2.4G Dual-Band Storage System
Europe’s home networks are extremely diverse. Older buildings rely on wide-coverage 2.4G, while newer homes enjoy high-speed 5G.
S2400 Pro intelligently switches between both:
-
Weak signals? Automatically switch to 2.4G for stability.
-
High bandwidth needed? Switch to 5G for efficiency.
Remote monitoring, dynamic pricing updates — no more connection anxiety.
-
More Generation Power — 4 × 1000Wp PV Input, “No Sunbeam Left Behind”
S2400 Pro comes with four independent MPPT trackers, each supporting 1000Wp, delivering a total of 4000Wp. Even with panels installed separately — balcony, rooftop, fence — each MPPT finds its optimal output. Solar utilization increases by up to 30%.
3. More Output Strength — 2500W Continuous / 5000W Peak
Powering the Whole Home, Even Off-Grid**
Ovens, air conditioners, washing machines — S2400 Pro handles them with ease.
-
2500W continuous charge/discharge
-
5000W peak for 5 seconds
Even if the grid fluctuates, essential household loads stay rock-solid.
4. More Ecosystem Flexibility — Compatible with 700+ Energy Providers
“One App to Run the Whole Home”**
S2400 Pro integrates into the Sunpura Home ecosystem, supporting Wi-Fi, Wi-Fi+LoRa, and 4G. It can connect with smart meters, infrared heaters, EV chargers, and sync with dynamic-pricing strategies from 700+ European energy suppliers. Which provider saves more? The app calculates it for you in one tap.
Beyond product innovation, we also focused on deeper industry collaboration:
-
13:30–13:45: EUPD Research awarded us Top Innovation 2025 — recognition of Sunpura’s long-term commitment to Europe.
-
14:00–15:00: Together with everHome and Priwatt, we hosted a joint session on market trends, technical execution, and new opportunities in European home energy.
We also brought a lucky draw — with S2400 Pro + EcoTracker as the top prize, and smart-energy bundles as runner-up prizes — bringing the “future of energy” directly into visitors’ hands.
Honoring Long-Termism: Built by Our Team’s Persistence — and Our Customers’ Trust
Standing beside the S2400 Pro, we can’t help recalling:
-
the R&D team spent three months perfecting MPPT accuracy,
-
the Germany service team fine-tuning every detail to uphold our 10-year warranty,
-
and the early customers from 2023 whose real feedback shaped every upgrade in the S2400 Pro.
Our biggest takeaway from three years in Düsseldorf is simple: The most meaningful achievements aren’t about one person running fast — but about a group of people walking far, together.
After this year’s show, many customers asked: “What are your plans for next year?” Our answer is clear: We’ll be back — with products that understand you even better, warmer service, and an even stronger commitment to long-termism.
The future of home energy isn’t just about powerful hardware — it’s about technology that truly understands people.
