We offer the Growatt TPM-E Three-Phase Smart Meter, designed for monitoring energy flow in compatible Growatt solar PV and energy storage systems.

This direct-connected energy meter supports grid export limitation and self-consumption monitoring. It communicates with compatible Growatt inverters via RS485 and Modbus RTU, making it a practical solution for residential and commercial photovoltaic installations.

Key Features

Three-phase energy metering: Designed for 3-phase, 4-wire (3P4W) electrical systems.

Export limitation: Supports export power control when integrated with a compatible Growatt inverter.

Self-consumption monitoring: Helps monitor energy flow within the solar installation.

LCD display: Enables convenient local readings and status checks.

Direct connection: Rated for 10 A nominal current and up to 100 A maximum current.

Easy installation: Designed for standard 35 mm DIN-rail mounting.

Communication: RS485 interface with Modbus RTU protocol.

Included accessory: Standard 15 m RS485 communication cable.

Certification: CE listed in the manufacturer's datasheet.
