400V High Voltage LiFePo4 Lithium Battery

Description

High voltage Battery storage

The EG Solar 400V DC 60kWh battery storage system is a high voltage system featuring 4 pcs LiFePo4 battery modules, each rated at 400V 16kwh. These 4 battery modules are connected in parallel to achieve a total voltage of 400V DC, resulting in a 64kWh battery storage system with total energy of 64kWh. This compact high voltage lithium battery system can be used as a UPS or solar energy storage system, and is compatible with most popular HV hybrid inverters on the market, such as Sol Ark, Deye, Goodwe, and others. The EGbatt HV battery design makes this system operate more efficiently and promotes green energy. The system includes an additional high voltage box. Each battery module can work independently, supporting discharging and communication. Each module supports 5kW of power, so the 4 modules together support a maximum of 20kW for both charging and discharging.

high voltage output will help to lower down the output current value.

System Overview

The EGbatt Hbrick-HV50A is a high-voltage lithium battery energy storage system designed for residential applications. It integrates a high-performance LiFePO₄ battery pack (314Ah / 51.2V nominal) with an internal boost converter that raises the output to 330–450V DC, directly compatible with most HV hybrid inverters.

An intelligent Battery Management System (BMS) monitors cell voltage, current, temperature, and balances cells to maximize lifespan. The BMS provides comprehensive protection against:

1. Over-voltage / Under-voltage
2. Over-current (charge/discharge)
3. High / Low temperature
4. Short circuit

Multiple Hbrick-HV50A units can be connected in parallel (max. 16 units) to increase total storage capacity and backup time.

The EGbatt Hbrick-HV50A

is a state-of-the-art high-voltage lithium battery storage system designed for residential and light commercial energy storage applications. With a nominal energy of 16 kWh and a robust 314Ah LiFePO₄ (Lithium Iron Phosphate) cell architecture, this system delivers safe, reliable, and efficient energy storage for solar self-consumption, peak shaving, backup power, and UPS functions.

Unlike low-voltage battery systems, the Hbrick-HV50A integrates an internal boost converter that raises the native 51.2V battery voltage to a 330–450V DC high-voltage output. This makes it directly compatible with most HV hybrid inverters on the market, eliminating the need for external transformers or complex wiring. The result is higher round-trip efficiency, reduced current losses, and a cleaner installation.

Whether you are retrofitting an existing solar system or designing a new home energy storage solution, the EGbatt Hbrick-HV50A offers a future-proof, scalable, and safe energy storage platform.

Key Features & Benefits

High-Capacity LiFePO₄ Chemistry
16 kWh usable energy (90% depth of discharge) – enough to power essential home loads through the night or during grid outages.
314Ah prismatic LiFePO₄ cells – known for exceptional thermal stability, non-toxic materials, and over 6000 cycle life.
Wide operating temperature range (0°C to 60°C) – suitable for garages, utility rooms, or sheltered outdoor areas (IP54 rated).

High-Voltage Architecture (330–450V DC)
Built-in boost converter – transforms low battery voltage to high voltage, matching modern HV hybrid inverters.
Lower current at higher voltage means thinner cables, less heat, and up to 95%+ round-trip efficiency.
Smoothing inverter integration – plug-and-play communication with leading inverter brands.

Intelligent Battery Management System (BMS)
Multi-layer protection: over-voltage, under-voltage, over-current, short circuit, high/low temperature.
Active cell balancing – extends battery lifespan and maintains capacity across thousands of cycles.
Real-time monitoring of voltage, current, SOC (State of Charge), and temperature.
Alarm & protection logic – automatically disconnects in fault conditions, protecting both battery and inverter.

Scalable Parallel Architecture
Up to 16 units can be connected in parallel for a total capacity of up to 256 kWh.
Automatic master-slave configuration – one unit acts as the master communicating with the inverter; slaves follow seamlessly.
Voltage matching guidance – pre-installation voltage balancing ensures smooth parallel operation.

Comprehensive Communication Ports
CAN bus (CAN1 / CAN2) – standard for most HV hybrid inverters.
RS485 (Modbus RTU) – for PC monitoring, data logging, and integration with energy management systems.
48V backup charging port (LINK1) – can wake up a deeply discharged battery using a 48V DC charger.
Parallel sync ports (LINK2/LINK3) – daisy-chain for control and address assignment.

Easy Installation & Maintenance
Wall-mounted or floor-mounted – compact footprint (972×528×162 mm) fits in tight spaces.
Natural convection cooling – silent operation, no fans to fail.
Clear LED indicators – quick status check at a glance.
Pre-assembled power cables and communication cables included in the box.

Safety & Certifications
IP54 ingress protection – dust-protected and splash-proof.
CE, UN38.3, MSDS certified – compliant with international transport and safety standards.
Fire-resistant enclosure – meets residential safety requirements.
No cobalt – LiFePO₄ is non-explosive, non-thermal-runaway prone compared to NMC.
