Smart Charging

Smart charging is an extra option for your charging station which is available at most charging points that we offer via Cable Soolutions. With Smart Charging you can charge your car smartly and minimize the one-off and annual costs for electricity connection. The charging points hereby have an additional RJ45 communication connection with with additional sensors to be placed. The Solarbox has 3 functions within Smart Charging:

  • Solar: ensures that your car will only be charged with the energy produced by your own solar panels.
  • Load Balancing: ensures that the car charger never exceeds the peak power of your connection. This prevents extra costs from your network operator. 
  • Panel Sharing: if you connect multiple charging points to an electrical connection, Panel Sharing ensures that the available power of the entire connection is smartly distributed if multiple vehicles are charging. If one of the vehicles is fully loaded, the remaining load capacity then goes to the vehicles that still have to be loaded.Smart Charging ensures that your charging station always makes smart use of the available load capacity.

By smartly charging your electric car with a Smart Charging charging point you can save up to hundreds of euros per year.


Use extreme caution when installing the charging station. It is recommended that the construction is carried out only with prior knowledge or by a trained professional.

The charging points of ratio are available with and without Load Balancing. The load balancing versions come in a master and a slave version. If you only install 1 load point with Load Balancing, you need a master. The versions offered here with load balancing are always Master's and are supplied with an additional measuring core which must be placed at the main connection in the meter box.

If you also want to place an additional charging point on the same mains connection, then a Slave in combination with a Master is sufficient. A maximum of 3 Slaves can be connected to 1 Master. If you want an extra Slave you can order it separately from us. These cannot be ordered directly via the website.

In order for this charging station to work with 32A and 3 phases, you need at least a 3 phase 400V connection of at least 3x35A. If you have less than 35A you can also set the charging point to a lower maximum charging current or connect to 1 phase.
