TSUNESS Recognized as a Leading SRDI Innovator

TSUNESS is honored to be recognized as a 2025 Specialized, Refined, Differentiated, and Innovative (SRDI) Enterprise, marking another major milestone in our continued pursuit of innovation across balcony solar, microinverters, and micro-storage technologies. This recognition reflects our role as an early pioneer and core technology leader in the global balcony PV sector, and our commitment to advancing consumer-centric clean energy solutions worldwide.Pioneering the “Solar-as-an-Appliance” Vision
Since 2019, TSUNESS has been shaping the evolution of balcony solar by making solar generation as simple and intuitive as modern home appliances.

Through six years of dedicated R&D, we have built a complete ecosystem covering:

Microinverters

Micro storage systems

Balcony solar hardware and structures

Supported by 100+ patents across modules, mounting systems, and plug-and-play control algorithms, TSUNESS now offers one of the market’s most complete balcony PV product families—from compact lightweight modules to microinverters spanning 300W–3300W.

Scenario-Driven Engineering for Real-World Self-Consumption

TSUNESS develops technologies tailored to real usage scenarios, enabling stable, safe, and efficient self-consumption systems.

Our multi-path anti-backflow solutions address diverse installation environments worldwide:

WiFi & WiFi-Mesh coordinated control

RS485 hardware-isolated anti-backflow

4G cellular models for low-signal regions

These technologies ensure system reliability and compliance across various grid conditions, home structures, and installation constraints.

Integrated Systems that Redefine User Experience

To address global demand for simple, reliable residential solar, TSUNESS created a fully integrated balcony PV solution combining:

High-efficiency modules

Microinverters

DIY or Pre-installed brackets

Zero-export function

This system enables true plug-and-play installation, significantly lowering complexity for end users and installers which earned major international certifications and are widely deployed across Europe, South Asia, and other regions.
