SEVR OPTI Three Phase CT Module & Clamp Kit for 22kW EV Charger

The SEVR OPTI SV-EVACC-CT22-SEM3 is a three-phase CT module and clamp kit designed specifically for the 22kW SEVR OPTI EV Charger. Installed at the property’s main electrical supply, it continuously measures real-time current consumption across the three-phase supply and communicates this data to the charger via Wi-Fi or RS485. This allows the Dynamic Load Balancing system to automatically adjust EV charging power around other site loads, helping reduce the risk of overload while improving energy use. It can also support solar integration by monitoring grid power flow and allowing the charger to respond to available surplus solar generation.
