Product Introduction

The VoltaNest Container Energy Storage System is a fully integrated, grid-scale battery energy storage solution available in 500kW/1205.7kWh (20ft) and 1000kW/2411.4kWh (40ft) configurations. Built with 3.2V/314Ah LFP cells and a cycle life of over 6,000 cycles, it supports on/off-grid switching, max PV input up to 1440kW, and 110% long-term derating capacity. Military-grade safety design, advanced fire protection (FM200/NOVEC1230 optional), intelligent air cooling, and smart EMS (RS485, TCP/IP) ensure reliable operation from 0 to +45°C at altitudes up to 5000m. Simplified deployment reduces on-site installation work by 70%, making it ideal for PV self-consumption, peak shaving, backup power, and microgrid applications.
