EU Stock-Deligreen 96kWh High Voltage LiFePO4 Battery 8000 Cycles HV Control Unit with WiFi Monitoring

96kWh High Voltage LiFePO4 Battery System

The HV-96K brings together high-capacity storage, precision-built modules, intelligent system control and dedicated EU-based service. Each module features PCB-integrated voltage sampling, laser-welded cell connections, engineered cell insulation and reinforced mechanical support, all designed for consistent assembly and long-term reliability.

Designed for compatible high-voltage inverters, this complete set includes six matched 51.2V 314Ah modules and one dedicated high-voltage Battery Control Unit (BCU). No mixing parts from different suppliers: you get one clearly defined 6-module + 1-BCU system, built to work together.

With master-slave battery management, touchscreen and Wi-Fi monitoring, and module-level cooling, the HV-96K is a powerful platform for large residential solar storage and commercial energy storage projects.

1. A Complete 96.46kWh High-Voltage Battery System

Each LiFePO4 module is rated at 51.2V and 314Ah, about 16.08kWh. Connected in series and managed by the central BCU, the six modules form a 307.2V high-voltage system with 96.46kWh of total nominal energy.

Working voltage range: 278.4-345.6V DC. Maximum current: 200A, for up to 61.44kW of DC power.

2. Advanced Battery Module Engineering — Built for Connection Integrity and Long-Term Performance

Six 16.08kWh modules, engineered beyond the cell specification

A great battery is more than great cells. Deligreen’s HV-96K pays equal attention to how every LiFePO4 cell is positioned, connected, insulated, sampled and cooled.

Each 51.2V 314Ah module delivers about 16.08kWh, and six modules combine to give you 96.46kWh of reliable home energy storage. Built with the same precision manufacturing used across Deligreen’s high-voltage range, the HV-96K is made for the EU market and made to last.

PCB-integrated cell voltage sampling — orderly signal routing

Deligreen replaces long, loosely routed sampling harnesses with an integrated PCB layout. The result is cleaner routing, more consistent assembly, fewer loose connections, and easier voltage monitoring and diagnosis.

Double-ring laser welding — robust, repeatable cell connections

Every cell connection in a Deligreen battery is joined with a double-ring laser weld, creating a solid, consistent electrical contact that stays secure through years of charging, discharging and temperature changes.

Each module is checked for polarity and insulation before welding and inspected for weld quality afterward. Unlike joints that depend on manual tightening, laser welding delivers the same precise result every time, so you get power you can count on.

Reinforced cell layout and insulating separation

Inside every module, cells are held firmly in place by a supporting structure with epoxy-based insulating separators. This keeps each cell properly spaced and electrically isolated, while the layout is designed to accommodate long-term cell expansion and everyday vibration.

The result is fewer mechanical and electrical connection risks over the battery’s service life. As with any LiFePO4 battery, proper use remains important for long-term performance.

Module cooling: airflow supported by a ventilated enclosure

Each module has its own fan-assisted cooling and a multi-opening ventilated metal housing. Module-level temperature sensing feeds the master BMS, which adjusts fan operation to match system conditions and keeps the battery running smoothly within its specified temperature range.

3. Intelligent Master–Slave BMS and Cloud-Connected Balancing

A battery this size needs more than a basic indicator. In the HV-96K, the BCU houses the master BMS, and every module has its own slave BMS (BMU) for cell-level monitoring and data-informed balancing. Connect via Bluetooth and check your system in real time from your phone.

Each module’s electronics track cell voltage and temperature and report to the central controller. The master BMS coordinates the whole system, so it sees far more than overall pack voltage, and technicians can pinpoint abnormal conditions faster.

• Cell and module monitoring: Cell voltage, temperature and system data at a glance
• Coordinated charge/discharge: Centralized control of voltage and current within system design limits
• Smart balancing: Integrated BMS balancing keeps cell-voltage differences under control
• Built-in protection: Overcharge, over-discharge, overcurrent and high/low-temperature protection
• Clear fault visibility: Alarms and diagnostic information shown on the touchscreen

Cloud-connected visibility and data-informed cell balancing

The monitoring architecture combines on-site BMS control with Wi-Fi-connected data access. According to Deligreen's manufacturing and technology materials, operating history can support data-informed balancing decisions, helping the management system recognize cell-voltage differences and select appropriate balancing actions. Physical monitoring and protective decisions remain functions of the battery electronics, even where remote data services are available.

The BCU is the heart of the system

The BCU brings the key electronics into one unit: the master BMS, DC fuse, soft-start circuit, charge/discharge circuits, 24V DC/DC supply, protection cut-off switch, touchscreen, Wi-Fi module and status indicators.

Its built-in soft-start circuit helps the battery connect smoothly to compatible inverters that don’t have their own soft-start function.

4. Smart Monitoring: Touchscreen, Wi-Fi and Detailed Diagnostics

Know what your storage system is doing

The integrated color touchscreen shows your system’s status right at the battery. Authorized users can view total voltage, state of charge (SOC), current, highest and lowest cell voltages, cell temperatures and relay status. If something goes wrong, the fault screen lists alarm names and timestamps, making troubleshooting quick and structured.

For users and technicians who need visibility away from the battery, the system includes built-in Wi-Fi remote monitoring and debugging capability, with cloud-connected access and historical operating data supported by the configured monitoring platform. The manual also lists CAN and RS485 communication interfaces for connection to suitable high-voltage inverter systems.

5. Engineered Protection for High-Voltage Energy Storage

Multiple protective functions, managed as one system

Built-in safeguards include cell overvoltage and undervoltage monitoring, overcurrent protection, temperature monitoring, a DC fuse and a protective cut-off switch.

The BCU also houses the soft-start circuit and central charge/discharge control, so key operating and protection functions are coordinated across the whole system rather than left to individual modules.

6. Dedicated Module Cooling and Space-Efficient Installation

Each battery module incorporates a cooling fan, supported by a ventilated sheet-metal enclosure. The master BMS can control cooling operation in response to temperature information supplied by the battery modules. This design helps dissipate operating heat and supports monitored thermal management.
