1. What is Load Balancing?

Load Balancing is the distribution of power between the different points of consumption. In other words, Monta automatically divides the available power over the vehicles that are charging.

Monta's system analyses the available capacity and how much power the vehicles require. Subsequently, power is distributed based on the maximum capacity of the connection. With the system, electric vehicles can always be charged, even if the installation has a limited capacity. Thus, no expensive investments have to be done in a more powerful installation.

Please note that Load Balancing is only available for Enterprise Teams. Here, you can learn more on how to upgrade your plan with Monta.

At Monta, we offer the following 3 methods for Load Balancing:

2. Static Load Balancing

Static load balancing describes a setup, where the site is set up under a static load. This means that the available power is evenly distributed to the charge points, whether they are being used, or not.

Example: A site has 40A available and 4 charge points that need to use it. With Static Load Balancing, each charge point receives 10A regardless of whether a car is charging there or not.

3. Dynamic Load Balancing

In a dynamic setup, each charge point is allocated current from a pool, based upon a set value. With this setup, a maximum current needs to be set, and the system will automatically distribute the available power among the charge points that are used at the time.

Example: In the Partner Portal, you have set that the maximum current the setup can use is 40A. This means, that if two charge points are being used, the system will allocate 20A to each of the charge point.

4. True Dynamic Load Balancing

This is the most advanced method of Load Balancing we offer at Monta. It's very similar to Dynamic Load balancing.

The key difference is that for this type of setup you need an additional external meter source, which is connected to the system. The role of the meter is to dynamically reduce the load that is shared across the charge point. The setup can work through either an API integration or ModBus integration.

Example: You have a maximum of 40A to use for a building and 4 charge points. The building is using 10A, which the external meter detects and reports to our central system.

Monta's system registers that 10A is used by the building and calculates that the charge points have 30A to share amongst each other (40A - 10A = 30A). Therefore, if two cars are charging, the charge points will be allocated 15A each.

Here you can read about the types of charge points and meters and Monta supports for Load Balancing.
