WattmonMEGA
The WattmonMEGA1) is the most recent and capable release of the Wattmon range of embedded data logging and control devices. The external connections are the same as for the WattmonPro, but the internal hardware is improved, with four times as much RAM (512 KB), 100 Mbps Ethernet, a processor clock of 200 MHz, 12-bit ADC inputs (4096 possible values for the full scale), and an expansion of the maximum number of RS-485 Modbus RTU/TCP devices (32 RTU, 10 TCP).
The MEGA uses the same OS as any of the Wattmons including the PRO, and is compatible with the same set of Modules and Accessories. The firmware has the same set of functions as all of the Wattmons and the PRO, but is expanded to take advantage of the hardware improvements. These changes add flexibility and speed, making it over twice as fast as the PRO and easier to customize for any application.
The MEGA can be used for any application in monitoring, control and data logging for the IoT. But particularly noted applications include:
- Inverter Monitoring - Inspect generation and efficiency of gridtie and hybrid inverters
- AC Power Monitoring - Supervise load and performance of substations and mini-grids
- Off-Grid Battery Monitoring - Observe battery voltage, current, SoC, charging trends and health over time
- Zero Export & DG Protection - Reduce active output power of multiple inverters to regulate energy generation
