The cFos EVSE is able to control other EVSEs (also from other manufacturers) including load management. For this purpose, one cFos EVSE is designated as the master and the other EVSEs are connected to the master as slaves. It is possible to link other EVSEs to a cFos EVSE using WLAN (Modbus TCP/IP) or a two-wire connection (Modbus RTU).
If several EVSEs are used at the same time, the maximum possible network connection power is often exceeded. This saves you the costs of upgrading your power connection. For single-family houses, the available mains connection power is usually 14.5 kW, and 34 kW if electrical hot water is available.
You must set the load management mode to "Monitoring" under "Settings" in all slaves. The same TCP ports or COM parameters and the same Modbus ID must be stored under the settings for the wallbox and meter as you have set in the master for the respective slave.
Yes. However, we do not recommend this due to the following disadvantages that are associated with it: An Internet connection is required for software updates (once the master-slave configuration has been set up, it no longer requires an Internet connection to operate). Access to the Master Box without an Internet connection is only possible via the cFos Power Brain Wallbox's own access point. You must manually set the time in the Master Wallbox and update it if necessary.
Without load management, the fuse could blow.
As soon as you have connected your cFos Power Brain Wallbox to the home network, you can read out the network address in the router menu.
Yes, you can use the supplied S0 meter or a Modbus energy meter for this. Here is a list of supported counters.
Ways to use the electricity meter. If, as described above, you have added meters to the configuration for each wall box and these are attached to the wall box, the cFos Charging Manager can determine the power consumption and the power currently drawn from each wall box and use it for load management. Without a counter, the cFos Charging Manager assumes that the car is always using the maximum charging current allocated to the wallbox (static load management).
A cFos Power Brain Master can manage up to 25 slave boxes.
With a cFos Power Brain Wallbox, you can manage up to 3 third-party boxes and any number of cFos Power Brain Wallboxes using the Charging Manager. If you want to connect more than 3 third-party boxes as slave boxes, you need additional licenses. cFos Charging Manager
