Key Features:

The Fox ESS AC Coupled 5.0kW AC1 Charger Inverter is a high-quality solution converting solar energy to AC energy stored in a battery. Use it to optimize energy consumption, store energy for future use, or feed excess energy into the grid. The system offers several advantages:

  • Advanced DSP control technology
  • Utilizes the latest high-efficiency power components
  • Advanced anti-islanding protection
  • Max efficiency up to 97.8%, THD <3%
  • Export limitation (CT/Meter/DRM0/ENSTOP)
  • WiFi remote control (with WiFi dongle installed)

Operating Modes

The Fox ESS 5.0kW AC1 Charger Inverter features four work modes to adapt to various needs:

  1. Self-use: Prioritizes battery discharge for local loads first, with the grid supplying power when the battery capacity is insufficient.
  2. Feed in priority: In the presence of an external generator, generated power is used for local loads first, then exported to the grid. Redundant power charges the battery.
  3. Force time use: Ideal for areas with peak and off-peak pricing. Allows flexible setting of charging and discharging times, with the option to charge from the grid.
  4. Back-up (EPS) mode: Supplies emergency power from PV or a battery during grid outages.

The Fox ESS 5.0kW AC1 Charger Inverter seamlessly integrates with smart Agile tariffs, with compatibility confirmed with Octopus Energy and other Economy 7 providers. It also supports an external backup generator for extended grid outages.
