Yes. It is possible to extend CT production and data exchange cables of Elios4you up to 20 metres, using shielded cables at least 2×0.75sq. mm long.
If the distance to cover is more than 20 metres, the two CT shielded cables of Elios4you Smart can be replaced with two RC wireless Energy Meters (single-phase or three-phase). It is not possible to replace the CT of the Power Reducer SA with one RC wireless device.
