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 easier. Depending on the model, the meters support single-phase two-wire or three-phase four-wire networks.

Key benefits of SPM-E/TPM-E

• Measurement accuracy: class 1 and measurement accuracy of 0.5% for voltage and current, 1% for power and 0.2% for frequency.
• LCD display: makes it easier to operate the meter and check readings.
• Compatibility with Growatt: compatibility with photovoltaic inverters and energy storage inverters from this brand.
• RS485 communication: Modbus RTU protocol, baud rate 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 the phase and neutral conductors 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 ensures communication.
