Scenario: Backup Power Solution for European Homes and Small Commercial Users Amid the Energy Crisis

  • Client Background: A German mid-sized home appliance retailer wanted a power solution that could serve both as an emergency backup and a daily energy-saving device for its VIP customers and stores in remote areas.

  • PurMars Solution: We customized the "Single Phase 220V PES Series" with power ratings of 3kW, 5kW, and 6.2kW.

  • Application Details:

  • Home Use: The 3kW/5kW models provide seamless backup for refrigerators, routers, lighting, and small heaters during outages. They also support peak load shifting to save on electricity costs.

  • Small Commercial Use: The 6.2kW model ensures up to 6 hours of backup for point-of-sale systems, critical lighting, and coffee machines, preventing business losses during blackouts.

  • Customization: We integrated specialized Schuko sockets per German standards, developed a custom APP interface, and applied the client's logo with a distinct color scheme.
