CT clamp (small model)

zappi & eddi are supplied with one wired CT terminal as standard.

The 22kW 3-phase Zappi comes standard with 3 CTs.

One (or 3 in case of a 3-phase inverter) additional CT clamp is needed if you want to see the real time output of your solar/wind system on the product's LCD display.

This is a smaller version of the standard CT clamp, you can use this CT to measure up to 40A. Moreover, this is not a "Clip-on" model, so you have to detach the relevant cable to put it through the CT. This is only for the advanced electrician !

With this Clamp Terminal, zappi can take measurements on the phase cable(s) of the main fuse, for its protection, the consumption of the house. the surplus of your own generation, but also for the yield of your energy system (solar panels or wind turbine).

With the 1-phase zappi and eddi, 1 CT is supplied as standard (with the 3-phase zappi, 3 CT clamps are supplied)

With an additional CT, you can also display the yield of your solar panels and read this on the display. It is not necessary for the correct operation to also place a CT on the inverter. This is only necessary to get a complete overview on the display (and via the HUB in the app) of all the information about where the power is coming from or going to.

For the zappi v1 models: If you want to do a 3-phase measurement, you must use 3 CTs in combination with harvi - You can only connect 2 terminals wired in the zappi v1.

For the zappi v2 models: If you want to do a 3-phase measurement, you can connect 3 clamps directly (wired), and/or connect 3 (extra) clamps wirelessly with a harvi
