Product Lines
Home energy storage systems: 5–20 kWh wall-mounted, stackable and all-in-one units built on LiFePO₄ cells, compatible with mainstream hybrid inverters including Deye, Growatt, Victron and Sunsynk, with CAN / RS485 / Modbus communication. Applications cover grid self-consumption, off-grid supply and backup power during outages.
Portable power stations: 600W–3000W output range with LiFePO₄ cells and 220–240V / 50Hz AC output, designed for household emergency backup, small-business power supply and off-grid outdoor use.
Manufacturing & Quality Control
Operating five production lines, the factory delivers a single-shift monthly capacity of 5,000 portable power stations and 1,000 home storage battery packs. Core processes cover cell sorting and matching, laser welding, BMS integration, aging tests and final assembly, governed by a three-stage inspection system (IQC–IPQC–OQC). Every batch undergoes industry-standard outgoing tests, including full-charge aging, high-low temperature cycling, dielectric withstand and vibration. Shipment quality consistently meets industry standards.

Warranty & Compliance Support
All products carry a 5-year warranty with spare-parts supply and remote technical support within the warranty period. For destination-market requirements we support customers through conformity procedures such as SONCAP (Nigeria), SASO / SABER (Saudi Arabia), EAC (CIS), INMETRO (Brazil) and SNI (Indonesia).

OEM / ODM Service
Standard workflow: requirement confirmation → solution design → sampling (5–7 working days) → certification adaptation → mass production → global delivery. MOQ starts from 100 units; lead time follows industry-standard schedules based on order volume. Customization covers casing printing and coating, retail packaging, firmware parameters, communication protocols and product configuration. Cell type and structural safety components are not open to modification, to ensure safety and batch consistency.
