Inverter solar Clamp

What is a CT clamp & a hybrid inverter?

CT clamps provide real-time data on the electrical current passing through the wire they encircle, which is essential for energy management systems in residential solar setups. A hybrid inverter is a versatile component that can convert DC electricity from solar panels or batteries into AC electricity for household use.

How many CT clamps does a single phase inverter have?

Single phase inverters will come with one CT clamp and three phase inverters will come with three CT clamps. These will be used to measure the GRID imports and Exports of your system. Different sized inverters will have a different CT clamp rating supplied but they will look something like this:

Why do you need a CT clamp for an inverter?

This helps in reducing electricity bills and optimising the use of renewable energy. Accuracy: CT clamps provide precise current measurements, allowing the inverter to make accurate decisions about energy distribution. Non-Intrusive: They can be installed without interrupting the power supply, making them ideal for residential setups.

Do I need a CT clamp for a string inverter?

When the inverter is set up as a string inverter and no export limitation is in place using a CT clamp is optional. With no CT you can set the inverter to ‘Selling-First’ this will use the PV to cover the property load and then export any excess to the grid. Without a CT you will only see the generated PV values recorded.
