Ruihan: Your Global Energy Manufacturing Partner
Ruihan New Energy is a Guangzhou-based manufacturer founded in 2018, focused on high-performance, high-safety energy products — portable power stations, home energy storage systems, solar inverters, solar panels and complete solar-plus-storage solutions.
Guided by a "quality first, reliability always" principle, our in-house engineering team has grown with the company — covering inverter control, BMS and energy-storage system design under one roof. Every product line is designed and manufactured in-house, so partners source less, verify less, and deliver more.
Our automated production runs to ISO 9001 & ISO 14001 standards with full-process quality control, supporting flexible OEM/ODM customization — from private-label portable power to complete home energy systems — for partners across 85+ regions.
