Energy meter – GROWATT – SPM-E – single-phase

SPM-E/TPM-E

SPM-E/TPM-E is a series of smart energy meters compatible with Growatt photovoltaic inverters and Growatt energy storage inverters. It provides class 1 measurement accuracy, and the LCD display makes operation and checking readings easy. Depending on the model, the meters support a single-phase two-wire or three-phase four-wire grid.

Key benefits of SPM-E/TPM-E

• Measurement accuracy: class 1 and voltage and current measurement accuracy of 0.5%, power 1% and frequency 0.2%.
• LCD display: makes it easier to operate the meter and check readings.
• Compatibility with Growatt: compatibility with this brand’s photovoltaic inverters and energy storage inverters.
• RS485 communication: Modbus RTU protocol, baud rate of 9600 and a 15 m RS485 cable included.
• Electrical parameters: nominal current 10 A and maximum current 100 A; input voltage 184–276 V AC between phase and neutral or 320–520 V AC between phases, depending on the model.
• Installation and environmental parameters: 35 mm DIN rail, IP51 protection rating and operating temperature from -25°C to +55°C.

Who is this a good choice for?

The series is designed for users of photovoltaic installations and energy storage systems with compatible Growatt inverters who need energy measurement and monitoring of readings on an LCD screen. Versions for single-phase and three-phase networks allow the meter to be matched to the network type, while the RS485 interface with the Modbus RTU protocol provides communication.
