Growatt TPM-CT-E-EU – three-phase smart meter (SDM630) with CT transformers
Growatt TPM-CT-E-EU is a three-phase energy meter (smart meter) based on the module SDM630, designed to work with inverters GrowattThe "CT" version measures current indirectly, through external current transformers (CTs), thus supporting installations with higher currents and power—where direct measurement is not possible. This system accessory provides the inverter with full information about the energy flow between the installation, the grid, and the building.
Thanks to the counter Growatt TPM-CT-E-EU The inverter "sees" how much energy is being drawn from the grid and how much is being fed back into it. This is the basis for energy management functions: export control (limiting the supply of surplus energy to the grid, zero-export), maximizing self-consumption, and precise monitoring of consumption in the application.
Opinion of the technical team PVGroup.pl
"Meter Growatt TPM-CT-E-EU We recommend the SDM630 wherever export control or accurate auto-consumption measurement is required, and the installation currents are too high for direct measurement. The version with CTs is standard in larger commercial and agricultural installations. We emphasize the correct selection and installation of transformers on the phase conductors and maintaining the measurement direction—this is crucial for the proper operation of the zero-export function."

What is the counter for? TPM-CT-E-EU
- Export control / zero-export — limits or blocks the transfer of surplus energy to the grid, in accordance with connection requirements.
- Maximizing self-consumption — the inverter controls production and storage based on the actual energy flow.
- Bidirectional energy measurement — precise information on consumption from the network and the return of surpluses.
- In-app monitoring — full data on consumption and production in ShinePhone / ShineServer.
Why the version with CT transformers
In smaller residential installations, direct-metering meters are used. In larger installations—commercial, agricultural, and industrial—phase currents are too high to pass directly through the meter. In such cases, indirect measurement is used via current transformers (CTs): the transformers are placed on the phase conductors, and the meter SDM630 reads the current from them. Growatt TPM-CT-E-EU this is exactly such a version - universal for high-power installations.
Compatibility and installation
Meter Growatt TPM-CT-E-EU works with inverters Growatt (including MIN series, MID, MOD, MAX and SPH) via a communication bus. The meter itself is mounted on a DIN rail in the switchboard, and the CTs are installed on the phase conductors at the metering point. Correct installation and configuration are required for the export control function to function, so installation should be performed by a qualified installer.

Most frequently asked questions
What is the counter for? Growatt TPM-CT-E-EU?
It is a three-phase smart meter (SDM630) that measures bi-directional energy flow and allows the inverter Growatt export control and maximization of self-consumption.
How is the CT version different from a regular counter?
The CT version measures current indirectly, via current transformers mounted on the phase conductors. This allows it to handle high-current installations where direct measurement is not possible.
What inverters does it work with?
Growatt TPM-CT-E-EU works with inverters Growatt, including the MIN series, MID, MOD, MAX and SPH, via the communication bus.
How are the meter and transformers installed?
The meter is mounted on a DIN rail in the distribution board, and the CTs are installed on the phase conductors. Installation and configuration should be performed by a qualified installer.
