The European branch of the Chinese multinational Sosen, with more than 13 years of experience and over 100 million LED drivers sold worldwide, is consolidating its presence on the continent. The company brings its expertise in power electronics applied to solar energy, focusing its strategy on hybrid solutions for the commercial and industrial sectors.
At the centre of this new phase is the three-phase hybrid inverter SSE-HH40-60K-P3EU — a high-voltage solution that combines versatility and power to operate both in grid-connected and off-grid systems.
With four independent MPPTs and a maximum photovoltaic capacity of 100 kWp, the unit provides exceptional flexibility to optimise the design of the solar field. Its dual battery channel (2 × 100 Adc) enables simultaneous charging and discharging, while its sub-10 millisecond switching ensures continuity even during unexpected grid failures.
According to Raúl Ruiz, Commercial Director of Sosen Europe, the product’s development responds to a growing market need: an all-in-one solution combining self-consumption, storage and full backup.
“Storage is the true driver of the energy transition; our goal is to offer genuine independence, even in industrial or rural environments disconnected from the grid,” he told Strategic Energy Europe.
The possibility of connecting up to eight units in parallel — reaching nearly 500 kW — expands its application to large-scale commercial projects.
It is no surprise that interest in such solutions has soared following the blackout that affected Spain, exposing the limitations of many self-consumption systems.
In this context, Ruiz explained that “many users had panels and batteries but were left without power during the outage”, underlining the importance of total backup and how a properly configured system can prevent multimillion-euro losses.
Announcements from Red Eléctrica regarding the need for system adjustments to prevent future blackouts have renewed business urgency, reinforcing the call for more resilient infrastructure and technologies that ensure operational continuity in the face of grid instability.
From an economic perspective, the return on investment for fully isolated systems ranges from two to four years, depending on backup energy costs and consumption profiles. However, the key value lies in service continuity, especially in sectors where an hour without electricity can entail significant losses.
The company highlights that its technology is ready for integration into energy communities and collective self-consumption, although it acknowledges that Spain’s regulatory framework still presents challenges.
Ruiz welcomed the advances introduced by the new draft Royal Decree, which extends the connection radius for shared self-consumption from 2 to 5 kilometres and includes associated distributed storage — steps he considers crucial to speeding up project deployment and enhancing sector competitiveness.
With an operational structure already in place and local technical service and stock in Europe, Sosen is committed to agile, close-to-market support for installers and distributors. Its expansion plan covers Spain, Portugal, Italy, Greece, Poland, Romania, Hungary, the Czech Republic and the United Kingdom — markets where storage and intelligent energy management are gaining strategic importance.
To engage with the sector, the company confirmed its participation at Genera 2025 (Stand 10E09), where it will officially present its line of hybrid inverters and its vision for integrating storage as an essential component of Europe’s new energy model.
Combining technological innovation, industrial expertise and local support, Sosen aims to establish itself as a key player in building a more autonomous and energy-efficient Europe.
