Power Electronics has reached 11 GW AC of installed capacity in the UK, building on more than 15 years of activity in the country’s solar and energy storage markets.
The UK was the first international market where the inverter manufacturer scaled rapidly, and remains its longest-standing market in Europe. Some of the earliest UK solar plants equipped with Power Electronics technology have now been operating for more than 15 years.
Its first UK solar plant was commissioned in 2011 and remains in operation today. Since then, the company has expanded into large-scale battery energy storage, including a major BESS project in 2025 involving 145 PCSK battery inverters for its first phase.
A second phase of the same project is set to use a further 150 PCSK units, while additional UK projects are deploying more than 150 PCSK GEN 3 units.
The company says its UK growth is supported by a local service organisation of more than 60 professionals, backed by spare-parts hubs and long-term manufacturing capability.
“Reliability over 15 or 20 years is not achieved through design alone,” explains Borja Monzó, UK Country Manager at Power Electronics. “It requires manufacturing quality, proven technology and a service organisation capable of supporting assets throughout their entire operational life. That combination is what allows us to lead the UK storage market and support new applications such as data centres.”
Power Electronics’ UK portfolio includes the PCSM battery inverter, offering power ratings of up to 5,360 kVA in an integrated medium-voltage architecture, alongside the HEM solar inverter and the Freesun DC/DC converter for hybrid solar-plus-storage projects.
The company said its experience in solar and storage is now supporting its expansion into new critical applications, including data centres, where long-term availability and resilience are becoming increasingly important.
