Product Introduction

The VN-HC-70 is a 70kWh high-voltage battery cabinet with an integrated air-cooling design, built for commercial and industrial energy storage. Inside a single robust outdoor-rated enclosure, it combines high-capacity battery pack modules (each with dedicated fan cooling), an intelligent BMS (Battery Management System) and an FSS fire suppression system for all-around safety. Working with a hybrid inverter, energy meter and transformer, and centrally managed by the EMS (Energy Management System) with web and mobile APP monitoring, it forms a complete solar-plus-storage solution connected to the grid and photovoltaic array — ideal for peak shaving, backup power, self-consumption and microgrid applications. As the larger sibling of the VN-HC-50, it shares the same cabinet platform, BMS and FSS architecture while delivering 40% more usable energy in the same footprint.
