Designed for larger single-phase arrays, the KH/KA Series offers high rates of output in 7, 8, 9 and 10kW options, with 3 or 4 MPPTs for maximum design flexibility. As part of Fox ESS modular solutions, the KH/KA Series can be paired with EP or CQ/EQ batteries and installed with or without panels (AC-coupled).
The KH/KA Series is a single-phase hybrid inverter designed for larger arrays, available in 7, 8, 9 and 10kW options.
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.
This flexibility allows a single platform to cover multiple use cases – reducing complexity for installers and future-proofing for homeowners.
The KH/KA Series is fully compatible with our modular battery ranges, allowing systems to scale as energy demands grow.
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.
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.
| Battery Model | Minimum # Batteries | Maximum # Batteries | Capacity range |
| EQ2900 | 2 (1 x EQM, 1 x EQS) | 7 (1 x EQM, 6 x EQS) | 5.76 – 20.16kWh |
| EQ4300 | 2 (1 x EQM, 1 x EQS) | 7 (1 x EQM, 6 x EQS) | 8.28 – 28.98kWh |
| EQ4800 | 2 (1 x EQM, 1 x EQS) | 9 (1 x EQM, 8 x EQS) | 9.32 – 41.94kWh |
| CQ7 | 2 (1 x CQM, 1 x CQS) | 7 (1 x CQM, 6 x CQS) | 14.04 – 49.14kWh |
| EP6 | 1 | 4* | 5.76 – 23.04kWh |
| EP12 | 1 | 4* | 11.52 – 46.08kWh |
*For installations of 2-4 EP batteries a junction box is required.
