Accessories M1-40 / M3-40 / M3-40-Dual
SolaX Power measurement accessories are advanced energy meters designed to work with inverters and photovoltaic installations. The series includes single-phase and three-phase models, offering high measurement accuracy, fast refresh time and simple, quick Plug-and-Play commissioning. Thanks to intelligent features, the devices provide safe and efficient control of energy flows in the system.
Key features Accessories M1-40 / M3-40 / M3-40-Dual:
- Plug-and-Play solution: Easy and quick installation thanks to ready-to-use current transformer configuration.
- High refresh rate: A refresh time of 50 ms ensures more precise and faster control of the system.
- Increased safety: The design effectively separates high-current circuits from low-current circuits.
- Intelligent regulation: Automatic adjustment of phase sequence and current transformer direction solves common installation issues.
- Support for multiple sources: Ability to monitor power drawn from the grid and from third-party inverters simultaneously (feature available in the dual-circuit M3-40-Dual model).
- Remote management: Supports remote configuration via the SolaX Cloud APP.
Who is this a good choice for?
The M1-40, M3-40 and M3-40-Dual measurement accessories series is an ideal choice for installers and residential and commercial photovoltaic system users who are looking for reliable tools to monitor electrical energy. These devices are suitable wherever high measurement accuracy of class 0,5 is required and the possibility of integration with advanced SolaX inverter systems.
