SolaX M3-40-Dual - 3-phase electricity meter with real-time monitoring

The SolaX M3-40-Dual electricity meter (MPN: 3252020026) accurately measures voltage, current, power, frequency, and other electrical parameters and can be easily integrated into existing energy systems. The DIN rail mounting saves space, and the wide LCD display clearly shows all relevant data. Unlike the M3-40, the M3-40-Dual can simultaneously monitor the current from the public grid and that from third-party inverters. With an update rate of 50 ms, the meter provides accurate, real-time power data that is crucial for efficient control of energy flows.

Highlights of the M3-40-Dual

• Plug & play CT solution for easy installation
• 50 ms high update rate for more precise and faster control
• Intelligent phase sequence and CT direction adjustment—automatically solves installation problems
• Supports remote settings via the SolaXCloud app
• Separates strong and weak currents for customized safety
• Able to monitor grid power and power from third-party inverters simultaneously

Intelligent phase sequence and CT direction adjustment

The meter automatically detects the phase sequence and direction of the current transformers (CTs). Installation errors are corrected automatically, ensuring accurate power measurement without time-consuming manual adjustments.

Remote access via SolaXCloud

Remote settings and real-time monitoring can be carried out via the SolaXCloud app. This allows centralised control and monitoring of energy flows, even without direct access to the meter on site.

Safety through separation of strong and weak currents

The separation of strong and weak currents ensures increased operational safety. This reduces the risk of damage to sensitive measuring components.
