One Factory. Six Product Lines.
Zero Middlemen.
Founded in 2018 in Guangzhou, Ruihan New Energy started with a single focus — solar inverters professionals can depend on. As our partners' needs grew, we expanded step by step into a complete solar and storage portfolio.
Today we operate as a one-stop partner across six in-house product lines. From a single component to a complete system, everything is designed and manufactured in-house: our partners source less, verify less, and deliver more.
Make clean energy accessible to every home and business.
Become the world's most trusted smart energy manufacturer.
