The company designs and manufactures switching mode power supplies rated from 11W to 240W+ for home appliances, office automation equipment, LED lighting, and industrial applications, alongside a renewable energy product line under the SOLAGE brand that includes grid-tied photovoltaic inverters (300W to 10K, with maximum efficiencies up to 98.5%), ESS power conversion systems (including 100kW grid-connected PCS), and lithium-ion and LiFePO4 battery modules. Product families also extend into PD-adaptors (45W/65W, USB-PD compliant) and automotive power components for controllers, motors, and sunroofs.

The business is B2B enterprise sales-led, selling directly to tier-1 OEMs in Korea and exporting to 17 regions across 12 countries. Anchor customer relationships include Samsung Electronics (SMPS core supplier since 2001, ECO partner since 2005, Supplier Council member since 2012) and Coway (SMPS supplier for water purifiers since 2007, named best partner in 2018). Pricing is quote-based with no public list pricing, consistent with custom OEM/ODM supply.

Manufacturing is distributed across three wholly-owned production subsidiaries: Shenyang (Liaoning Province, China, 9,000m², ~600 workers), Qingdao (Shandong Province, China, 10,184m², ~350 workers), and Binh Phuoc (Vietnam, 16,086m², ~350 workers), supported by a 115-person Korean HQ and a Donggwan R&D Center established in 2011. Total workforce is approximately 1,415 across all sites. The company holds multiple certifications including KS marks for SOLAGE inverters, lithium-ion battery certification, Green Technology Certification from the Ministry of Knowledge Economy, and INNO-BIZ status, and has received Korean government recognition including the 2009 Presidential Prize for Corporate Innovation, multiple Export Tower awards, and 2015 Deloitte Fast 500 Asia Pacific recognition.

Broad incumbents

• Delta Electronics: Taiwanese power electronics giant with a portfolio spanning industrial SMPS, telecom power, EV power, and renewable energy inverters. Overlaps Powernet's SMPS, inverter, and automotive power electronics businesses, but at vastly greater scale and broader product breadth.
• Lite-On Technology: Taiwanese conglomerate with a power systems division manufacturing SMPS, LED drivers, and inverters for global OEMs. Comparable in product mix and B2B OEM model to Powernet, though operating at materially larger scale and with a more diversified technology portfolio.
• TDK-Lambda: Subsidiary of TDK Corporation manufacturing industrial SMPS, DC/DC converters, and power supplies for OEM customers worldwide. Overlaps with Powernet's industrial and high-efficiency power supply offerings, with comparable regulatory certifications (Level VI, etc.) but at greater scale.

Emerging players

• SolarEdge Technologies: Global solar inverter and power optimizer specialist with focus on module-level power electronics. Comparable in solar inverter/MLPE product category to Powernet's SOLAGE line, but serving primarily distributed generation markets in the US and Europe.
• Sungrow Power Supply: China's largest solar inverter manufacturer and a major supplier of ESS PCS. Comparable to Powernet's SOLAGE inverter and ESS PCS product lines, but at vastly larger scale and with global utility-scale market share that Powernet's SOLAGE line does not approach.
