Source a Broad Product Portfolio from One Supplier

Residential ESS, high-voltage batteries, commercial and industrial BESS, all-in-one systems and related solar storage solutions can be matched to different market segments without managing multiple battery vendors.

03

Build Your Brand with OEM & ODM Manufacturing

Customization can cover logo, enclosure appearance, product labeling, packaging, manuals, capacity configuration and communication requirements, subject to product and project feasibility.

04

Verify Compliance Before Committing to Volume

Model-specific certifications and transport documents can include UL, IEC, CE/CB, UN38.3 and other regional requirements. Confirm the destination market first so the correct product and documentation path can be reviewed.

05

Reduce Procurement Risk with Engineering & After-Sales Support

Technical review before production helps confirm capacity, voltage, inverter communication and application fit, while remote support and warranty coordination continue after delivery.

From RFQ to Repeat Supply

A Clear Procurement Path for Wholesale, OEM and Project Orders.

Define the commercial and technical requirements early so pricing, samples, certifications, production and logistics can be aligned before the purchase order.

  1. STEP 01

    Send Your RFQ

    Product type, target capacity, estimated quantity or project scale, buyer type, destination market and required delivery window.

  2. STEP 02

    Technical & Compliance Review

    Voltage, inverter matching, communication, application, certificates, labeling and market-entry documentation are checked.

  3. STEP 03

    Confirm Commercial & OEM Details

    Pricing, quantity, branding, enclosure, packaging, manuals and approved technical configuration are locked before production.

  4. STEP 04

    Production, QC & Shipment

    Manufacturing, inspection, testing, transport documentation, battery-safe packing and international shipment coordination follow the confirmed order.

System Integration Ecosystem

Compatibility Validation for Leading Inverter Platforms

For B2B procurement, inverter compatibility is verified by battery model, inverter model, firmware and communication protocol. Send the exact inverter specification so the engineering team can confirm integration before volume ordering.
