Metering – Overview of GivEnergy Meters (GEM120CT, GEM630MCT, LoRa)

GivEnergy systems rely on precision metering to ensure accurate import/export data and intelligent power flow control. The three main metering devices used across installations are:

Meter – GEM120CT

Type – Single-phase

Application – Domestic and light commercial single-phase systems

Compatible Systems – Gen 3, AC Coupled 3.0, All-in-One


Meter – GEM630MCT

Type – Three-phase

Application – Commercial and high-power three-phase systems

Compatible Systems – 6kW, 8kW, 10kW, 15kW, 20kW HV inverters


Meter – GIV-LoRa-LCD

Type – Wireless bridge

Application – Long-distance metering communication (up to 6 km)

Compatible Systems – Any system with distant meter-inverter connection


Core Function

Each meter provides accurate measurement of:

  • Energy consumption and generation (import/export)
  • Voltage, current, and frequency
  • Power factor and load balance
  • Bidirectional energy flow (for hybrid operation)

All meters communicate with the inverter via RS485 Modbus, enabling the inverter to:

  • Calculate true load and grid import/export values
  • Control charge/discharge operations
  • Display metering data in the GivEnergy Portal
