Why we use the range
Equipment is only useful when it fits the site.
Compact all-in-one, hybrid-inverter and modular battery options for residential and small-commercial storage, monitoring and planned growth.
Fox ESS offers grid-tied and hybrid inverters, modular batteries, all-in-one systems, EV charging and cloud monitoring. Its residential range covers compact entry points through to larger modular storage, so the system can be shaped around space, existing PV and intended energy use.
Product breadth
The useful parts of the range.
This is a practical, paraphrased guide to the manufacturer's published range. Exact models, approvals and availability are checked against the current project information before quotation.
Hybrid & grid inverters
Single- and three-phase inverter choices for new solar, storage and suitable retrofit arrangements.
Modular batteries
Low- and high-voltage storage families that can be configured to the compatible inverter and required usable capacity.
All-in-one systems
Integrated PowerQ, Evo and related formats combining inverter, storage, backup options and smart control in a compact package.
Selection model
Four tests before a product reaches the quotation.
Brand familiarity is not enough. We look at what happens during normal operation, credible faults, maintenance and future change.

Whole-life assessment
Why it may suit a particular environment.
Resilience
Compatible backup outputs can maintain selected loads, but changeover, neutral/earthing behaviour, surge demand and realistic autonomy must be designed and proven.
Performance
Matched battery and inverter communication enables charge limits, state monitoring and energy-flow control to work as a coordinated system.
Environmental value
Storage can increase self-use of solar and shift grid demand; lifecycle value depends on usable cycles, temperature, tariffs and avoiding oversizing.
Parts & support
A UK technical hub, documented compatibility and monitoring support maintenance. Warranty registration, firmware and replacement strategy are checked for every system.
Our application
Selected against evidence—not a favourite badge.
We review load profile, PV strings, DNO limits, phases, battery location, fire and ventilation considerations, backup circuits and expansion rules.
- Survey the supply, load, interfaces and physical environment.
- Confirm current technical data, approvals and system compatibility.
- Define maintenance access, records, spares and software responsibilities.
- State the chosen equipment and material assumptions in the quotation.
- Test, commission and hand over the work included in our scope.
Lifecycle note
Manufacturer names and advertising imagery are used with permission for product identification and to explain equipment our team works with. Their inclusion does not imply endorsement or a formal partnership unless expressly stated. Product ranges, firmware, warranties, approvals and spare-part availability can change. We verify the current position for each quotation and do not promise indefinite continuity of supply.
