Key Features:

  • The Fox ESS H1 3.0kW Hybrid Charger Inverter is a premium-quality device designed to convert solar energy into AC energy for storage in a battery. With flexible configuration and plug-and-play setup, it offers built-in fuse protection and an IP65 rating for outdoor installations.
  • Four Work Modes:
    • Self-use (with PV power): Optimize self-consumption by using energy produced by the PV system. Excess energy charges the batteries and is exported to the grid.
    • Self-use (without PV power): When solar panels don't provide power, the battery powers home appliances, and the grid supplies power when the battery capacity is insufficient.
    • Feed-in Priority: Utilize an external generator to power home appliances first, exporting excess power to the grid and charging the battery.
    • Force Time Use: Ideal for peak and off-peak pricing. Use off-peak electricity to charge the battery, and flexible settings allow choosing whether to charge from the grid. Use stored energy during peak times.
    • Backup (EPS) Mode: Supply emergency power from PV or a battery during grid outages to support home loads.
  • The Fox ESS H1 3.0kW Hybrid Charger Inverter seamlessly integrates with smart Agile tariffs, offering compatibility with Octopus Energy and other Economy 7 energy providers. Additionally, it supports external backup generators for prolonged grid outages.
  • Fast Delivery Across the UK: Enjoy the benefits of the Fox ESS H1 3.0kW Hybrid Charger Inverter with quick 2-3 working days delivery within the UK (longer to the Highlands, islands, and Northern Ireland).
