Home energy management system.


Eddi is an eco smart energy management system, it diverts surplus power from solar PV or wind generation to a designated heating appliance (or two sequentially). This excess energy will go directly to a designated appliance such as an immersion heater. Eddi allows you to stop exporting energy back to the grid and saves money on energy bills.

Technical characteristics:

  • Power control technology: VariSine™ pure sine wave PWM (pulse width modulation).
  • Bypass switch: Integral on/ off/ bypass switch.
  • Cooling: Rear mounted passive cooled heatsink.
  • Indicators: LED indication: Supply On, Heater 1 and Heater 2 active.
  • PWM resolution: 0.1%.
  • Measurement accuracy: ±1%.
  • Power conversion efficiency: 97.5% (typical).
  • Rated input power: 3.68 kW.
  • Standby power consumption: 3 W.
  • Generator size supported: No limit (subject to 100 A per-phase grid supply).
  • Heater load size: Minimum: 100 W; maximum: 3.68 kW maximum.
  • Economy tariff sense input: 230 V AC sensing (2.5 kV isolated).
  • Wireless interface: 868/ 915 MHz (proprietary protocol) for wireless sensor and remote monitoring options.
  • Grid current sensor: 100 A maximum primary current, 16 mm maximum cable diameter.
  • Supply cable entry: Rear, bottom or side option.
  • Weight: 4.3 kg (excluding wall bracket).

Features and benefits:

  • 3.68 kW/ 16 A maximum heater load.
  • Supports two heaters (sequentially).
  • Integral bypass switch.
  • VariSine™ PWM technology.
  • Fan-less cooling.
  • Built-in programmable boost timers.
  • Energy savings data logging.
  • Graphical back-lit LCD screen for ease of use.
  • Overload and short-circuit protection.
  • Expansion module option - two extra outputs with temperature control.
  • Wall mounting bracket for ease of installation.
  • Fully EMC and safety compliant (CE).
  • Works alongside battery storage systems.
