Products Description
This 120kW/209kWh mobile battery energy storage system is a fully integrated fast-charging solution for mid-sized stations, industrial parks, and commercial centers.
It features secure, long-lifespan LiFePO4 battery storage, automotive-grade BMS cell monitoring, and an active fire protection system. This all-in-one solar storage charging system integrates batteries, a bidirectional PCS, solar controllers, and fast-charging modules into a single unit. Pre-commissioned at the factory, it requires minimal on-site installation, drastically cutting O&M and setup costs.
Key Product Performance & Features
1. All-in-One Integration (Turnkey Solar-Storage-Charging) Our system fully integrates the battery bank, bidirectional PCS, solar charge controller, and fast-charging modules in a single unit. With high compatibility, it connects seamlessly to PV arrays, the utility grid, and EV charging posts. Pre-commissioned at the factory, it simplifies on-site installation, slashes project delivery times, and reduces civil construction costs.
2. High-Power Fast Charging (120kW Dual-Gun Output) Supporting 120kW high-power fast DC EV charging with dual guns, it is compatible with global charging protocols (including GBT, CCS1, CCS2, and CHAdeMO). It delivers rapid power to two vehicles simultaneously, maximizing vehicle turnover and operational efficiency for mid-sized charging hubs, commercial parks, and communities.
3. Multi-Energy Synergy (Optimized Operation Modes) The system seamlessly supports multiple intelligent modes: solar priority, grid priority, peak shaving, and emergency power backup. It utilizes green solar power to charge EVs, dramatically lowering electricity bills. During peak hours, battery discharge offsets grid demand, while off-grid mode automatically kicks in during power blackouts to keep critical loads running.

Multi-Level Safety Systems
Automotive-Grade Intelligent BMS
At the core of the system's safety framework is an automotive-grade intelligent Battery Management System (BMS). Unlike standard industrial controllers, this premium BMS delivers ultra-precise, real-time monitoring of cell-level voltage, current, and temperature dynamics. It constantly calculates the State of Health (SoH) and State of Charge (SoC), maintaining perfect cell uniformity during intense high-power charging cycles.
6-Level Active Safety Protection
The infrastructure is governed by a proactive 6-level active hardware and software safety loop. The system instantly detects anomalies and triggers automated isolation protocols to protect the asset and connected vehicles from:
- Overcharging & Over-discharging
- Over-current & Over-voltage
- Short-circuits & Insulation faults
- Over-temperature fluctuations & Reverse-polarity connection
FAQ
Q: Can the dual charging guns deliver the maximum rated power simultaneously?
A: The system is equipped with 2 charging guns featuring premium 7-meter wires. The maximum charging power (120kW for standard models and 160kW for the flagship model) can be dynamically distributed between the two guns to charge two electric vehicles simultaneously.
Q: How does the system handle thermal runaway risks?
A: This is backed by a 6-level active hardware/software protection loop and a built-in automated Aerosol fire protection system that isolates faults and suppresses thermal threats within seconds.
Q: How well does the system perform in extreme outdoor weather environments?
A: The entire enclosure is built to a rugged IP54 or IP55 ingress protection rating, completely sealing internal components from rain, snow, sand, and dust.
Q: What does the on-site installation process look like? Is it a "turnkey" solution?
A: It is a 100% all-in-one, fully integrated turnkey system. The battery bank, bidirectional PCS, solar charge controllers, fast-charging modules, and safety systems are entirely pre-assembled and fully pre-commissioned at our factory prior to shipment.
Q: Can we customize the physical enclosure branding and technical specifications for our region?
A: Yes. We can tailor the exterior color and branding, modify the enclosure dimensions to fit specific footprints, configure the exact charging gun standards (CCS/GBT/CHAdeMO), and adapt software communication parameters to fit your local network.
