Key Features

  • This is a flat vector illustration illustrating the operation of a home off-grid solar system. Against a light blue sky and green grass background, the central image features a white, two-story modern house with a sloping roof. Above the house is the bold blue title, 'Off-grid solar system'. Four blue solar panels, labeled 'Solar panels', are mounted on the dark gray roof. A bright yellow line tracing the flow of electricity extends downwards from the roof, connecting to a small gray 'Charge controller' mounted on the exterior of the house. To the left of the controller, a yellow arrow connects to four white, floor-mounted energy storage battery modules arranged side-by-side. From the battery modules, an orange arrow extends upwards, pointing to the air conditioning unit mounted on the second-floor exterior wall, labeled 'Electric loads' in blue. The diagram is clearly composed, visually illustrating the flow of electricity in a home's independent solar-energy storage system through yellow and orange lines and text labels.
    All‑in‑One Off‑Grid Power Integration
    The system integrates a 6kW inverter, MPPT controller, and LiFePO₄ battery into one unit, reducing installation time and wiring complexity while improving reliability for off‑grid deployments.
  • A 3D model image showcasing the explosive disassembly and technical analysis of a rack-mounted energy storage battery structure against a clean, light gray gradient background. The main subject is a white, vertically stretched and disassembled rack, broken down from top to bottom into multiple mechanical components: the top layer is a flat white chassis cover; following this are two layers of white cuboid main control and battery chassis modules with control panels and cooling fans; below that is an independent battery chassis module in a disassembled, suspended state; the base is a gray 'Standard 19-inch Rack Mount' with four orange adjustable horizontal feet. On both sides of the chassis module, four small gray metal lugs for securing and connecting side rails are also suspended in the air. The image is surrounded by five white boxed technical labels with leads: the upper left corner reads ‘Modular & Scalable: 16kWh to 272kWh’; the right side, from top to bottom, reads ‘Smart BMS: Cloud-Edge Monitoring & Balancing’, ‘Active Thermal Management’, ‘Grade A LiFePO4 Cells’, and at the bottom, ‘Standard 19-inch Rack Mount’. At the bottom center, the system's basic specifications are printed in bold: ‘51.2V 314Ah-HV Rack Mount Battery’. The entire image, presented in a meticulously disassembled engineering style, clearly showcases the battery system's internal construction and modular assembly process.
    15.36kWh High‑Safety LiFePO₄ Battery Storage
    Equipped with 51.2V LFP cells, the system delivers long cycle life, high thermal stability, and multi‑layer BMS protection, ensuring safe and consistent performance in residential and remote environments.
  • This image combines a physical product with text showcasing a residential energy storage system that supports flexible capacity configuration. At the top of the image are two prominent lines of yellow italicized English: ‘Flexible capacity configuration’. Against a clean, light gray wall background, three white, vertical, stacked energy storage units stand side-by-side, their height increasing from left to right in a stepped layout: the first unit on the left consists of a top main control module and two battery modules stacked together, each with a blue capsule-shaped grip and a black horizontal handle; the second unit in the middle is of medium height, consisting of the same top main control module (equipped with a micro LCD screen) and four battery modules stacked below; the third unit on the right is the tallest, consisting of a top main control module and six vertically stacked battery modules below. All three units have curved support legs and exquisite craftsmanship. The visual comparison of the stacked layers vividly demonstrates the modular and robust characteristics of this energy storage series, allowing for flexible capacity expansion.
    Modular & Scalable 51.2V Battery Architecture
    Stackable battery modules allow flexible capacity expansion, enabling installers and distributors to configure systems for different load requirements and future energy growth.
  • This is a high-tech promotional image showcasing a smartphone app for remote monitoring of a residential green solar energy storage system. In the foreground on the left, a hand holds a white smartphone, its screen clearly displaying the green and white energy management app interface, including a complex power flow topology diagram, battery percentage, and a data list below. Above the phone, three progressively larger blue Wi-Fi signal ripple icons are blurred and overlaid. The background is a modern, white, irregularly shaped detached villa with a wide, sloping roof covered in deep blue solar photovoltaic panels. The villa's ground floor features large, floor-to-ceiling windows, emitting warm yellow light. On the outdoor ground floor to the right of the villa, a white, vertical, modular energy storage unit is placed, also topped with a small blue Wi-Fi signal icon. The entire image cleverly combines the software interface with the real-world architecture, vividly conveying the convenience of smart home energy management.
    Smart Monitoring & Intelligent Energy Management
    Real‑time monitoring via app or communication ports (CAN/RS485) enables remote diagnostics, load management, and system optimization for installers and end users.
  • A 3D concept model showcasing a full range of customizable energy storage systems (ESS) products against a pure white background. From left to right, three identical sets of white, industrial-style modular energy storage cabinets, but differing in capacity and size, are arranged from low to high: On the left is a 'Household ESS' for residential use, consisting of two side-by-side, low-profile, stacked white battery cabinets, each with five layers of modules stacked together and featuring striking light blue decorative lines; in the middle is a 'C&I ESS' for commercial use, consisting of two side-by-side medium-sized, enclosed, white integrated electrical cabinets with long, honeycomb-shaped ventilation louvers on the doors; on the right is a 'Utility ESS' for grid-scale applications, consisting of four tall, deep, heavy-duty container-style white energy storage cabinets arranged in parallel, their imposing presence integrating high-density dual-row power modules, intelligent circuit breakers, and complex power distribution display panels. The overall composition is neat and the sense of technology is strong, perfectly presenting a full-matrix hardware ecosystem for energy storage that can flexibly meet the customization needs of OEMs.
