Description
xVoltacon Energy Cube 30kW–120kW Hybrid Inverter with 30kWh Expandable Lithium Battery
The Voltacon Energy Cube is a scalable hybrid energy storage system built around the InfiniSolar WP 30kW inverter and the EC605 high-voltage lithium battery bank. With G99 approval, IP65 weatherproofing, and the ability to parallel up to four inverter units for a combined output of 120kW, it is designed for commercial, industrial, and large residential installations that require high-capacity reliable power with battery backup.

Product Overview
The Energy Cube is configurable to your project requirements. The default configuration provides a 30kW inverter and 30kWh energy storage. For systems requiring higher output or longer autonomy, additional inverter and battery units can be added. Up to four inverter units can be paralleled to deliver 120kW of single or three phase output, and battery banks can be expanded to 120kWh by stacking additional EC605 modules.
The 30kW AC charger allows the battery bank to be fully recharged from the grid in approximately one hour, making it particularly effective in areas with frequent power outages or load-shedding, where fast recharge between outages is critical.
When two or more batteries are included, the HVC05 parallel control module is supplied. This module contains the copper busbars for distributing current evenly across the battery bank and mounts directly on top of the battery stack.
Applications
- Commercial and industrial buildings requiring large-scale energy storage
- Three phase properties with high peak power demand
- Off-grid and hybrid systems in areas with unreliable grid supply
- Large residential and agricultural energy independence projects
Installation and Safety Notes
This system must be designed, installed, and commissioned by a qualified electrical engineer experienced in large-scale battery storage. G99 notification and DNO approval are required for UK grid connection. High-voltage lithium battery banks present serious hazards if incorrectly installed. Do not attempt installation without the appropriate engineering qualifications and grid approvals.
