Easee Equalizer P1 (90501UK): Smart Load Balancing for Modbus Energy Meters

Integrate intelligent load balancing into your Easee EV charging system with the Easee Equalizer P1 (90501UK). This version is specifically suited for installations utilising a compatible Modbus RTU (RS-485) energy meter. These meters often employ CT (Current Transformer) clamps for accurate measurement of the total current (Amps) being drawn by the property, suitable for supplies potentially rated at 100A or significantly higher, common in larger homes or commercial installations. The Equalizer monitors this energy usage via the meter and dynamically adjusts the power delivered to your Easee One or Easee Charge Charging Robot(s), preventing overload and optimising performance.

Ideal for Modbus Meter Installations (incl. CT Clamps)

If your property uses an energy meter communicating via the Modbus RTU (RS-485) protocol (often paired with CT clamps by the meter manufacturer), this Equalizer variant is the appropriate choice. The datasheet confirms Modbus connectivity via the RJ12 port using the included 1.5m cable. This allows the Equalizer to accurately read the site's total power consumption in Amps and kWh, enabling it to intelligently manage the load from one or multiple Easee chargers and ensuring the installation stays within the measured supply limits (e.g., up to 100A or the CT/meter rating).

Prevent Overloads and Enable Faster Charging Based on Amps

By constantly monitoring the total load (Amps) measured by the Modbus meter, the Equalizer prevents the combined demand of your EV chargers and other appliances from exceeding your supply capacity or main fuse rating. It automatically reduces charging power during peak times and increases it when spare amperage capacity is available, ensuring you charge as fast as safely possible without tripping breakers. This is vital for managing multiple chargers effectively on higher capacity supplies often found in commercial sites.

Unlock Solar Charging and Energy Insights

Connect the Equalizer to leverage the full capabilities of your Easee system. As outlined in the product information, it enables solar charging modes, allowing you to prioritise using surplus solar generation (when detected via low building load in Amps) for your EV. You can also monitor your property's overall energy consumption trends (Amps and kWh) directly within the Easee App, providing valuable insights for energy saving.
