Is it possible to extend the CT clamps on the Dura-i?

Yes, the CT clamps on the Dura-i inverter can be extended by up to 15 meters using a CAT5 coupler. However, ensure the CT cable is kept at least 200mm away from any power cables or sources of electromagnetic interference (EMI). If the CT cable must cross power cables, do so at a 90º angle. For installations where the energy storage system (ESS) is more than 25 meters from the main grid supply, an REM (Remote Energy Monitor) can be used to assist.
