【Rimini, Italy | March 18, 2025】BYD Energy Storage, a global leader in renewable energy innovation under BYD Group, has made a strategic leap in residential energy solutions with the debut of its fully-integrated Battery-Box HVE energy storage system and next-gen Power-Box inverters. The landmark announcement occurred during the Key Energy 2025 exhibition at Rimini Expo Centre, marking a new era in customizable home energy management.

Revolutionary Battery-Box HVE: Modular Design Redefined 

The new flagship system introduces groundbreaking modular architecture with two core units:

- HVE4.2 Module: 4.29kWh | 76.8V | Ultra-slim 140mm profile | 42.1kg

- HVE6.4 Module: 6.45kWh | 115.2V | Space-efficient 499mm width | 61.1kg

 

Through intelligent modular stacking, the system achieves unprecedented scalability:

- Single Tower Capacity: 6.4kWh (base) → 23.6kWh (4-module max)

- Multi-Tower Expansion: Parallel connection of 3 towers → 70.92kWh total capacity

Key Technological Advancements 

1. Space-Optimized Design: 140mm depth makes it the slimmest solution in BYD's portfolio, supporting flexible wall/floor mounting

2. Smart Energy Ecosystem: Integrated BYD Energy APP enables real-time monitoring, remote diagnostics, and OTA updates

3. Industry-Leading Warranty: 15-year performance guarantee backed by over 1.1 million global installations

Synergistic Power-Box Inverter Solutions 

The energy storage system pairs with two new hybrid inverters:


Single-Phase Power-Box SH Series (3-6kW) 

- 35A bidirectional current flow

- 97.7% peak efficiency

- 200% surge capacity for seamless grid transitions


Three-Phase Power-Box TH Series (5-15kW) 

- 98.2% conversion efficiency

- IP66 weatherproof certification

- 150% peak output with<10ms grid-switching

- DC18A compatibility with high-efficiency PV modules


Both inverters feature 24/7 smart monitoring and predictive maintenance capabilities through BYD's cloud platform.

Market Strategy & Executive Insight 

"2025 marks our transition to complete energy ecosystems," stated Jiang Feng, Residential Energy Solutions Director at BYD Energy Storage. "While maintaining partnerships with third-party inverters for existing Battery-Box lines, the HVE-PowerBox integration represents our commitment to delivering turnkey solutions for modern smart homes."

Commercialization Timeline 

- European Market Launch: June 2025

- Phase II Product Expansion: Q2 2025 (European-specific solution previewed)


The new solution maintains backward compatibility with existing BYD HV/LV Premium systems, offering customers flexible upgrade paths. With its combination of modular scalability, intelligent management, and industrial-grade reliability, the HVE series positions BYD at the forefront of the residential energy storage revolution.
