Product Introduction

The VN-HS series is a high-voltage stacked battery energy storage system available in 13 capacity configurations from 64.31kWh to 257.23kWh, built with next-generation 51.2V/314Ah LiFePO4 cells (4 to 16 modules in series). With high-voltage battery technology, it achieves over 98% energy conversion efficiency and superior energy density, ideal for high-demand residential and commercial applications. The standard rack-mounted design integrates seamlessly into existing power infrastructure, significantly reducing installation and maintenance costs while maximizing space utilization. Pre-assembled modules and plug-and-play interfaces enable rapid deployment, and the modular architecture supports flexible system configuration and future capacity expansion. An intelligent BMS provides real-time monitoring with triple hardware protection against over-voltage, over-current and overheating, ensuring long-lasting safety and reliability. Communication via CAN/RS485, cycle life ≥6,000 cycles.

FAQ

Q1: What capacity options are available in the VN-HS
A1: 13 configurations from 64.31kWh to 257.23kWh (VN-HS-64 to VN-HS-257), using 4 to 16 battery modules of 51.2V/314Ah connected in series, with rated voltages from 204.8V up to 819.2V.
Q2: What battery cells are used?
A2: Next-generation 314Ah LiFePO4 cells (51.2V per module), delivering higher energy density, longer cycle life (≥6,000 cycles at 90% DOD) and enhanced safety.
Q3: Can the capacity be expanded later?
A3: Yes. The modular architecture allows flexible system configuration, and modules can be added to scale capacity as your energy needs grow.
Q4: How is the system protected?
A4: An intelligent BMS provides real-time monitoring with triple hardware protection against overcurrent, overvoltage, undervoltage and short circuit, plus overheating protection.
Q5: How is it installed?
A5: Standard rack-mounted integration with pre-assembled modules and plug-and-play interfaces for quick deployment, suitable for indoor installation (IP20, natural cooling).
Q6: Which inverters can it work with?
A6: It communicates via CAN/RS485 and is designed to pair with hybrid inverters for solar self-consumption, backup power and commercial energy management. Please contact us for the compatibility list.
