OPTIONAL HARDWARE

CLIPON80A-COIL-3

The CLIPON80A-COIL-3, or commonly named “external coils” allows active load balancing in residential buildings, both in locations with and without their own energy production, e.g., using PV panels. The main function is to prevent the main MCB from tripping due to the EV charging.  

It consist of a set of three current transformers that can conveniently be clipped around the incoming wires of your electrical installation.  

Combined with the Enovates’ user app*, you can even decide to only charge when your PV-panels are generating enough electricity, or to limit the allowed charging based on total power consumption of the house instead of just setting a current limit (valid from firmware version 2.10 onwards).  

*Please note that for specific grid types, limitations may apply

Product brief

Easy to install on every household grid installation with clip-on coils, no need to interrupt the installation 

Real time bi-directional energy flow detection allowing for optimal energy monitoring

Obtain ultimate green e-mobility in combination with Enovates chargers

Optimize your grid usage to save on electricity costs

Application

Typical usage is a single family home with one standalone charging station.  

It is possible to use it in a small charging hub as well, up to 80A. The CLIPON80A-COIL-3 will then be connected to the master, who uses this as an input for load balancing within the charging hub.  

The CLIPON80A-COIL-3 works based on current transformation (ratio = 1:2000). The transformed current is then measured inside the charging station.  

The coils are mounted in the electrical cabinet and should be connected via an STP cable to the charging station.  

It is in some cases possible to only mount one out of three coils, limited functionality may apply.  

The table below gives an overview of the possible combinations between grid type, charging station connection and whether only current limiting is possible (= protecting the main MCB from tripping) or if power limiting is possible as well (= optimizing energy usage). 
Grid type = three phase STAR (WYE)
Charging station connection = single phase
Current Limit: Yes
Power limit: No (*1)
Grid type = three phase STAR (WYE)
Charging station connection = three phase
Current Limit: Yes
Power limit: Yes
Grid type = three phase DELTA
Charging station connection = single phase
Current Limit: Yes (*2)
Power limit: No
Grid type = single phase
Charging station connection = single phase
Current Limit: Yes
Power limit: Yes

(*1) a future firmware improvement intends to calculate the power of L2 and L3 based on the voltage of L1, allowing slightly suboptimal power limiting for this use case
(*2): Suboptimal when injecting into the grid, because currents are always seen as positive 

Compatible products

The CLIPON80A-COIL-3 can be combined with the Single Wallbox.
