NexBlue Zen 2 (Current Sensor)
NexBlue Zen 2 helps residential installations to use available power more effectively by monitoring energy use to support dynamic load balancing and solar surplus charging. Equipped with dual Ethernet terminals and two external antennas, it connects locally to NexBlue chargers via Wi-Fi, LAN or Nexus RF without relying on a smart meter. It also supports load shedding, and the appropriate protection device (MCB) can be selected based on site requirements.
What is included in the package?
Not included, choose to fit your site
Choose the protection device and additional external current sensor that suit the installation, instead of using fixed components that may not be needed.
Optional
3-in-1 clamps or a Rogowski coil can be used for solar generation monitoring(not required for solar surplus charging).
Optimize your energy usage
Popular science
Every building has a limited amount of power available. Dynamic load balancing measures how much electricity the building is using and adjusts EV charging accordingly. When other appliances need more power, the charger reduces its output. When more power becomes available, charging can increase again. This helps protect the installation from overload while making effective use of the available capacity
Solar surplus charging uses available solar energy to charge your EV instead of sending the excess back to the grid. NexBlue Zen 2 can do this without extra hardware by working with your existing solar system. It automatically adjusts the charging current so the EV only uses the surplus power that would otherwise be exported.
Load Shedding allows the EV charger to respond to external control signals for both grid management and safety. When a load shedding signal is received, the charger temporarily reduces its charging power or triggers an emergency stop. Once the signal is cleared, charging can increase again.

Hardware Issue Resolution Process for NexBlue Products
- Send us an email at support@nexblue.com and you will receive faster response within 3 business days.
- Or contact the installer or authorized dealer from whom you purchased the NexBlue product to initiate a warranty claim.
- The NexBlue partner must verify that the unit is safely powered and operational, and then contact the NexBlue support team for an initial remote diagnosis.
- In cases where remote resolution is not possible, NexBlue will arrange an on-site intervention to address the issue.
- Should hardware replacement be required, NexBlue will dispatch the replacement unit to the authorized dealer. The defective hardware must be sent back to NexBlue, utilizing the provided prepaid return shipping label.
Yes! The NexBlue Zen 2 communicates with our NexBlue chargers using a local radio frequency, which we call it Nexus RF. It will continue to function even when not connected to the network via Wi-Fi or Ethernet. However, we always recommend connecting the NexBlue Zen 2 to the network so that you can remotely monitor the status and access energy statistics on the go.
In extreme conditions where NexBlue chargers don't receive signals from NexBlue Zen 2 for more than 3 minutes, it is necessary to implement a lower charging current for safe charging. Charging will return to normal once the chargers reconnect with NexBlue Zen 2.
You can adjust the Fallback current accordingly in the Settings of NexBlue Zen 2.
No, Zen2 does not require additional accessory for Solar Surplus Charging, the additional 3-1 CT clamp or Rogowski Coil is just for Solar generation monitoring.
