【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.
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
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
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.
"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."
- 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.
