Sync Energy (BG) EVAB1ESP120: Single Phase Dynamic Load Balancer Kit with 120A CT Clamp

Safely manage multiple home EV chargers on a standard single-phase supply with the Sync Energy (BG) EVAB1ESP120 Dynamic Load Balancer Kit. Housed in a sleek white steel enclosure (IP20 rated for indoor installation), this intelligent unit prevents overloading your main fuse or supply cable. It constantly monitors your property's total power consumption and communicates with up to 16 connected SyncEV chargers, automatically adjusting their charging rates to keep the overall load within safe limits.

Avoid Supply Overloads in Homes

Installing two or more EV chargers can easily exceed the capacity of a typical domestic electricity supply, leading to tripped breakers or potentially dangerous overloads. The EVAB1ESP120 solves this by implementing dynamic load balancing. As described in the product literature, it ensures reliable charging for all connected vehicles without requiring expensive upgrades to your incoming electrical supply.

Complete Kit for Single Phase Setups

This kit provides a convenient solution for most UK homes. It includes the dynamic load balancer unit pre-installed in an IP20 rated, gloss white steel enclosure, ready for wall mounting. Crucially, it also comes supplied with one 120A CT (Current Transformer) clamp, suitable for monitoring the total current on typical single-phase domestic supplies. Communication with chargers is handled via RS485 connection.

Scalable and Reliable Charging

Engineered for ease of use and future expansion, this system supports up to 16 chargers. The balancer ensures power is distributed efficiently and equally amongst the active chargers based on the available capacity. The unit features over-current and fault protection, plus status indicators (RGB LED and buzzer), and comes with a 3-year warranty for confidence.
