What is Dynamic Load Balancing

Usually, every building has limited power to use for different electronic appliances. Dynamic load balancing is like having a smart system in your product that acts like a traffic controller for energy distribution.Imagine NexBlue Zen as a power commander, ready to monitor the power flow to all home appliances, and adjust the power goes to our NexBlue EV charger to make sure it works with maximum efficiency. This means the energy in your house can work more smoothly and quickly, without being overwhelmed or underused. It's like making sure the charger is always just busy enough, but not too busy while charging, so everything gets done faster and better. Overall, NexBlue Zen's smart balancing act happens as the work comes in, making your product adaptable and efficient all the time.

What is Solar Surplus Charging

NexBlue Zen helps charge your electric vehicles using renewable energy from sources like solar or wind power. With optional 3-in-1 CT clamps for solar surplus charging, it can track how much energy your solar panels are producing. NexBlue Zen uses this information to make sure your EV charges using just the right amount of solar energy.
This way, you get to charge your EV using clean, renewable energy, which is better for the environment and can also save you money on electricity bills.

Does NexBlue Zen function without a network connection?

Yes! The NexBlue Zen 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 to the network so that you can remotely monitor the status and access energy statistics on the go.

What is the Fallback current for NexBlue Zen?

In extreme conditions where NexBlue chargers don't receive signals from NexBlue Zen 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.|
You can adjust the Fallback current accordingly in the Settings of NexBlue Zen.
