Privacy & enquiries
This website does not use advertising or analytics scripts. When direct submission is available, selecting “Send enquiry” sends the details you enter and any optional electricity-bill attachment to our server for private storage and delivery to our team. Attachments are not uploaded when merely selected and are not made publicly accessible. We use these details to respond to your enquiry and manage the related business discussion.
If direct submission is unavailable, the form offers an email draft or a copy of your brief. Opening a draft does not send it; you send it from your email application. We do not save unfinished form entries in browser storage. Our hosting, private storage and email providers process information needed to operate these services. Please share only the information needed for an initial discussion; drawings and detailed specifications can follow by email.
For personal-data questions, contact hello@ruianglobal.com. External websites linked from this site operate under their own policies.
About the imagery
The Japan installation references use photographs from the supplied project reference material, attributed to Green Energy & Company / Green Energy Plus. They show the named installations and are distinct from the AI-generated equipment and infrastructure illustrations used elsewhere on this website. Those illustrations communicate product families and system context; they are not records of supplied products, supplier facilities or completed Ruian projects.
For conceptual renderings, equipment, proportions, connections and layouts are illustrative. Product appearance, configuration, dimensions and installation requirements follow the selected manufacturer’s documentation. The power journey and system map are explanatory views, not electrical designs.
About the system map
The map shows illustrative AC and supplier-described DC arrangements, not single-line electrical designs. Protection, redundancy, bypasses, UPS batteries and auxiliary loads are omitted.
Site BESS connects through a conversion and step-up skid at the MV bus. Generation voltage matching and the packaged-substation boundary vary by project. DC backup batteries are separate from site BESS and require compatibility qualification. HTS is an optional cable system on the illustrated incoming link. UPS and IT equipment are shown as system context.
“Documented equipment” means product material is available, not that every configuration is certified or suitable for every site. Ratings, compatibility, certification scope, availability and supply responsibilities are confirmed for the selected equipment.
Technical & commercial information
Public family descriptions support an initial discussion. They do not replace a project-specific datasheet, engineering assessment, quotation or contract. Specifications, availability, evidence, support and commercial terms are confirmed for the selected configuration.
Technology perspectives are areas of evaluation. References to third-party research or specifications do not imply endorsement, certification or a commercial partnership. Supplier records are not presented as Ruian-delivered projects.
