Adding a FOX Failover System
A FOX failover system was included to provide backup support for selected circuits during a grid interruption. Failover operation depends on the system design, available battery charge, connected circuits, and the amount of electricity being used when an outage occurs.
Prioritising essential circuits helps available battery capacity support the parts of the property that matter most during a temporary loss of grid power.
Connection and Compliance Documentation
The project records included responses relating to G98 and G99 requirements. These processes apply to electricity-generating equipment connected to the distribution network, with the appropriate route depending on the system specification and connection arrangement.
Export limitation and final commissioning documents should be retained with the system records alongside electrical certificates, equipment details, warranties, and handover information.
Estimated Annual Performance
Based on an indicative yield of approximately 905 kWh per installed kWp, the 13.8 kWp array could generate around 12,500 kWh of electricity in a typical year.
For illustration, if 70% of that electricity is used within the property at an avoided import cost of £0.25 per kWh and the remaining 30% is exported at £0.15 per kWh, the system could provide an estimated annual financial benefit of approximately £2,750.
Using an assumed avoided grid-emissions factor of 0.177 kg of CO₂ per kWh, annual generation could correspond to approximately 2,210 kg of avoided carbon emissions.
These figures are illustrative rather than guaranteed. Actual performance and savings will depend on solar conditions, system configuration, household consumption, battery use, export payments, and electricity tariffs.
