Nexblue Zen (Current Sensor) is an advanced solution for dynamic load balancing and solar surplus charging. It is ideal for homes without smart meters and can easily communicate with Nexblue chargers via Wi-Fi, LAN or radio frequency (Nexus RF) locally. With built-in Bluetooth, the load balancer can be easily configured and used without the need for Wi-Fi. Nexblue Zen is designed for simplicity and can be installed by an electrician in less than four minutes thanks to the quick-connect terminals, built-in power supply module and the circuit breaker (MCB). In addition, it is easily configured together with the charging box via the Nexblue Partner app.
