China Ring Main Unit Manufacturer, Supplier, Factory

Box type photovoltaic pre installed substation integrates high-efficiency PV inverters, intelligent power distribution, and temperature control systems in a single unit, ensuring stable operation across -40℃ to 60℃ (IP65 certification). Full ODM/OEM customization is available, with options ranging from structural design to smart monitoring modules, proven by 30+ overseas PV projects and a yearly failure rate <0.3%.

As the core equipment for distributed energy access, the new energy prefabricated substation (Huashi box transformer) is reconstructed and designed according to the "dual carbon" standard: using all copper windings and intelligent temperature control system, the loss rate is greatly reduced. The new energy prefabricated substation (Huashi box transformer) supports photovoltaic/energy storage multi scenario grid connection.

Container energy storage system is centered around "high reliability+low TCO", using A-grade lithium iron phosphate battery packs (IP67 protection), paired with an intelligent BMS system, supporting operation at -30 ℃~55 ℃, and designed for a lifespan of over 10 years. Supporting ODM/OEM services, customizable 20 foot/40 foot cabinet types, integrated with optical storage and charging modules, have been successfully applied in more than 30 projects such as Southeast Asian industrial and commercial energy storage and European microgrids.
