Current transformer (CT) clamps installed by our licensed electricians to feed accurate grid and solar readings to your monitoring, battery or solar-matching EV charger.
From $190 (Supplied and installed), including GST. Indicative starting price: the final fixed price is confirmed in writing after a site assessment.
A current transformer, commonly called a CT clamp, measures the current flowing through a cable without cutting into it. Monitoring systems, batteries and smart EV chargers rely on CTs to know how much power your home is importing or exporting. A solar-matching EV charger, for example, uses that reading to charge the car from surplus solar instead of grid power.
The CT Clamp Kit is from $190 supplied and installed. This is an indicative starting price; the final price depends on how many CTs are needed, single or three-phase supply, the distance from the switchboard to the device and whether wireless or wired communication is used.
CT problems are usually simple: a clamp on the wrong cable, facing the wrong direction or on the wrong phase. The result can be a battery that charges from the grid or an EV charger that never sees surplus solar. We place, test and verify every clamp against real loads before leaving, and our licensed electricians do the work safely inside the switchboard. If existing CTs are the cause of odd readings, we correct them rather than selling you equipment you do not need.
Owners of monitoring systems, batteries or smart EV chargers that need accurate CT readings to track usage or charge the car from surplus solar.
CT clamps must match the device they report to. A clamp from one monitoring system will not necessarily work with another, even if it looks the same, because ratings and outputs differ.
If you already have CTs and the readings look wrong, the fix may be repositioning rather than new parts.
1. Request a quote and tell us which monitor, battery or EV charger the CTs are for.
2. We confirm the correct CT type and number for your supply.
3. Our licensed electricians install the CTs and cabling in your switchboard.
4. We configure the device and test readings against real loads and solar export.
5. We show you how to check the readings in your app or charger.
The price shown is an indicative starting price; the final fixed price is confirmed in writing after checking your equipment and supply.
CT clamps are installed only by our licensed electricians and are not supplied for self-installation.
CTs must be compatible with the connected device; unsupported equipment may need a different solution.
Wireless CT links need a signal check, and long distances or thick walls may require wired communication.
Switchboard defects found during installation are reported and quoted separately.
