On March 8, 2026, Light+Building 2026, the world's premier trade fair for lighting and building services technology, officially kicked off at the Frankfurt Exhibition Center in Germany. ONESTO has set up its booth at D61E in Hall 10.2, where it is showcasing a full range of innovative products and solutions. We are now engaging in in-depth discussions with global industry professionals to explore the latest cutting-edge trends and development directions in the field.

At this exhibition, ONESTO showcased six core product lines, covering diverse needs in the fields of building electrical and new energy.

Digital Feed Pillar Solution:

The series of fuse disconnect switches offers efficient power distribution with a modular design tailored for smart buildings.

It features high-quality materials, optimized arc-extinguishing, and heat dissipation for reliable operation and low-temperature performance. With sizes 1-3, the switches are suitable for both single and three-pole operation in 185mm busbar systems and are compatible with existing market products, supporting both new installations and system expansions.

Solar System Solution:

Onesto offers comprehensive energy solutions for industrial and commercial applications, featuring on-grid inverters from 2kW to 125kW, hybrid inverters ranging 3.6kW to 30kW, and intelligent energy storage batteries between 5kW and 44kW. These are integrated with industrial-grade AC/DC dual protection systems, enabling smart and dynamic optimization of photovoltaic power output.
 

By connecting smart meters with hybrid inverters in real time, the system can automatically manage the coordination between power generation, storage, and the grid, supporting peak-valley load balancing and improving overall energy efficiency.

PV Components & String Box‌：

Onesto's series of pv combiner boxes offers various specifications ranging from 4 to 52 channels, supporting highly flexible modular configurations. Built-in components can be freely combined according to customer needs, such as SPDs, MCBs, disconnect switches, and fuses, achieving "one box, multiple functions" for safety management.

The meticulously designed structure not only ensures the reliability of system operation but also facilitates future expansion and maintenance, providing comprehensive protection for the efficient operation of photovoltaic systems.

Circuit Protection Devices Series:

Covering a full range of equipment including circuit breakers, surge protectors, residual current operated devices (RCDs), and residual current circuit breakers, providing comprehensive safety protection for building electrical systems and robust safeguards for users' power environment.

Air ciruit breaker & electronic devices:

Air circuit breakers possess high breaking capacity and stable protection performance, providing reliable safety assurance for power distribution systems.

Distribution board & enclosure:

Offering standardized and customized power distribution solutions to adapt to different power distribution needs in various scenarios, combining practicality and flexibility.
