KSTAR, a global leader in energy solutions, successfully organized the Customer Workshop 2025 under the theme “Connected from Power to Delivery,” with participation from its strategic partner OSW – a leading distributor and solution provider in renewable energy sources. The event was attended by over 60 key installers and representatives from OSW’s Management Board. Through immersive factory tours, technical seminars, and cultural experiences, the workshop day showcased KSTAR’s innovation and production excellence in energy storage and management, strengthening the strategic partnership between both companies.
During the event, guests visited KSTAR’s smart technology factory and product showroom, gaining direct insight into the company’s advanced production processes and innovative solutions. KSTAR experts then presented industry trends and the latest technological solutions, followed by live demonstrations. The presentations featured residential energy storage systems (ESS), single-phase and three-phase from the BlueSpark series, with power ratings from 3.68 kW to 12 kW, as well as the new generation of commercial and industrial energy storage systems BluePulse KAC50DP2+BC107DE2 and BluePulse KAC125DP2+BC233DE2.
The workshop day incorporated elements of cultural heritage and special artistic performances, which enriched the event format and was received very positively by participants.
