Polar Power designs and manufactures DC power generators and renewable energy systems for telecommunications, military, electric vehicle, marine, and industrial applications, with output ranging from 5 kW to 50 kW. The company offers four main product lines—base power systems, hybrid power systems integrating battery storage, DC solar hybrid systems, and mobile power systems—leveraging proprietary DC-based technology that delivers higher efficiency than conventional AC systems and integrates directly with batteries and solar installations. Revenue comes primarily from direct product sales, aftermarket parts, remote monitoring services, and installation support, with telecommunications serving as the dominant customer base, while military, EV charging, and emerging-market microgrids represent growth opportunities.
