A True Inverter Factory – Not a Trading Company

One of the biggest frustrations among U.S. buyers is unknowingly sourcing from middlemen. What sets Congsin apart is that it is a genuine, full-process inverter manufacturing factory — not just a reseller or agent.

  • 🧪 Aging and load testing for 100% of units

  • 🏷️ On-site OEM branding: stickers, silk screen, color boxes

  • 🚛 Weekly container shipments to U.S., Europe, Southeast Asia

This direct-to-factory model allows Congsin to offer better pricing, shorter lead times, and full customization, which makes it the ideal OEM inverter supplier for U.S. wholesalers.
