Inverter

The KH/KA Series is a single-phase hybrid inverter designed for larger arrays, available in 7, 8, 9 and 10kW options.

Battery

Pair with Fox ESS high-voltage batteries, including EP, EQ and CQ battery ranges.

The KH/KA Series removes the need to choose between system types.

  • DC Coupled – Ideal for new installations, maximising efficiency by storing energy directly from PV
  • AC Coupled – Perfect for retrofits, integrating seamlessly with existing solar systems
  • Battery Ready – Install now, without batteries, adding storage later with no system redesign

This flexibility allows a single platform to cover multiple use cases – reducing complexity for installers and future-proofing for homeowners.

ENERGY STORAGE

KH/KA Series battery options

The KH/KA Series is fully compatible with our modular battery ranges, allowing systems to scale as energy demands grow.

EP battery range

The Fox ESS EP range is a flexible modular, wall-mounted storage solution, available in two models: the EP6 (5.76kWh) and the EP12 (11.52kWh). Designed for easy scaling, up to four units can be connected in parallel, providing a total storage capacity of up to 23.04/46.08kWh. This makes the EP series ideal for everything from smaller residential setups to larger systems needing substantial storage.

KEY FEATURES

EQ/CQ battery range

The Fox ESS EQ/CQ range combines compact design with modular flexibility, making it a popular choice for scalable home energy storage. Available models include EQ2900 (2.88kWh)EQ4300 (4.32kWh), EQ4800 (4.66 kWh) and CQ7 (7.02kWh), these compact, floor-mounted modules can be stacked to build the ideal capacity for any installation.   See the sizing guide below for details of storage scalabilty.
