• Temperature Sensor Inputs: Includes two PT1000 temperature sensor inputs for enhanced heating control logic.
• eSense Input: Allows connection to economy tariff meters for optimised energy usage based on cheaper electricity rates.

Why We Recommend This Product: This board unlocks advanced control strategies for your eddi, allowing for more sophisticated integration with heating systems and energy tariffs.

Maximise self-consumption of your solar or wind energy with the myenergi eddi power diverter (EDDI-16A1P02H). Eddi intelligently diverts surplus generated electricity to heat water or rooms for free, instead of exporting it to the grid.

• Divert Surplus Energy: Automatically uses excess solar/wind power (up to 3.68kW/16A) for heating loads (e.g., immersion heaters).
• Reduce Energy Bills: Minimise exported energy and reduce reliance on importing energy for heating, saving money.
• Smart Control & Monitoring: Built-in WiFi/Ethernet, programmable timers, graphical display, and app monitoring.

Why We Recommend This Product: eddi is a leading eco-smart device for maximising the use of your own generated renewable energy for heating, significantly improving payback on solar panels. Works seamlessly with harvi.

The MyEnergi Libbi Control Module enables seamless communication between your solar inverter, battery storage and myenergi devices. A required component for operating the full Libbi system effectively.

• Central hub for all Libbi components and smart scheduling
• Required to integrate Libbi batteries and inverters
• Works with myenergi app for remote control and insights

Why We Recommend This Product: It’s the essential brain behind the Libbi energy storage system—small, simple and critical for smart solar control.

Why We Recommend This Product: A reliable optimiser that improves panel performance and simplifies system design—ideal for complex rooftops.

The SolarEdge Energy Meter K2 provides accurate export/import monitoring across single or three-phase systems, essential for SolarEdge optimisers and smart EV integration.

• Compatible with 1Ph and 3Ph systems (230/400V)
• Supports SolarEdge inverter, EV charger and battery setups
• Modbus RS485 communication ensures seamless data sharing

Why We Recommend This Product: A reliable energy management hub for homeowners and businesses using SolarEdge smart energy solutions.

Simplify your myenergi installation with the innovative harvi wireless energy monitoring sensor. Harvests energy from your cables to transmit CT clamp readings wirelessly to your eddi or zappi, eliminating the need for wired connections.

• Wireless CT Readings: Transmits data from connected CT clamps wirelessly (up to 65A per phase with included clamps).
• Energy Harvesting: Cleverly powers itself from the energy field around the monitored cable – no batteries or extra wiring needed!
• Simplifies Installation: Avoids running hard-wired sensor cables back to the main myenergi device.

Why We Recommend This Product: harvi drastically simplifies eddi and zappi installations by removing the need for wired CT clamps, using clever energy harvesting technology for power.
