Product Introduction

The VN-HR-70 is a stacked high-voltage battery system delivering 70kWh of storage through 10.24kWh×N stackable modules (optional configuration) in a single tower rack. Each battery module features dedicated fan cooling, safety handles and status indicators for simple installation and maintenance, while the bottom control unit manages the whole tower. The modular ×N design allows flexible capacity expansion — add modules as your energy needs grow. Integrated with a hybrid inverter and managed by the EMS (Energy Management System) with web and mobile APP monitoring, it works seamlessly with photovoltaic arrays, meters, transformers and the grid — an ideal choice for commercial and industrial solar-plus-storage, backup power, peak shaving and self-consumption.
