Fox ESS Introduces Power Cube, Bringing Flexible Home Energy Storage into One Compact System

MELBOURNE, Australia, Oct. 20, 2026 /PRNewswire/ -- Fox ESS, a global leader in renewable energy solutions, has introduced Power Cube, an all-in-one residential energy storage system combining the inverter and batteries in a sleek, stackable design. Engineered for simpler, faster installation, it helps Australian households manage their energy needs today while allowing flexibility for the future.

The launch follows SunWiz's announcement that Fox ESS ranked No. 1 in Australia for installed energy storage capacity in H1 2026, reinforcing the company's strong position in the market.

By integrating essential components into one compact system, Power Cube streamlines installation and can help reduce installation time and costs. Its modular EQ5500 batteries offer storage capacities from 10.92 kWh to 49.14 kWh across two to nine modules, allowing homeowners to choose a system that suits their household energy needs.

"Power Cube has been designed with the Australian market in mind," said Brooks Richard, Managing Director of APAC & Middle East at Fox ESS. "It delivers superior round-trip efficiency and a flexible range of capacities that align well with Australian household energy needs and available battery rebate tiers. Just as importantly, its integrated design simplifies installation, helping installers deliver a complete energy storage solution with greater ease."

Power Cube combines this flexibility with features designed for everyday performance and convenience:

• Power options for different homes: Single-phase models from 5–12 kW (CEC Approved) and three-phase models from 5–15 kW (coming soon), all supporting up to 200% PV oversizing.
• A compact, integrated design and IP66 rating support indoor and outdoor installation.
• An integrated gateway with 63A on-grid full-home backup support.
• Built-in battery protection: Inter-cell insulation and an aerosol unit in each battery module provide two levels of protection, from cell to pack.
• Integrated heating helps maintain battery performance in colder conditions.
• Fox Cloud 2.0 with AI enables real-time monitoring and remote configuration, with Wi-Fi, LAN and Bluetooth connectivity.

Backed by a 10-year product warranty, Power Cube brings installation simplicity, expandable storage and smart energy management together in one residential solution. For installers, it offers an integrated system designed to streamline delivery; for homeowners, it provides flexibility as their energy needs evolve.
