# ENP-RS232-MPP
Note
This module is discontinued. Monitoring and control of Watchpower enabled inverters (Voltronic, MPP Solar, etc) is possible with Enapter ENP-RS232 (opens new window) and MPP Solar Single Mode Blueprint (opens new window) or MPP Solar Parallel Mode Blueprint (opens new window)
# RS-232-MPP Module
The RS-232-MPP Module monitor and manage MPP Solar Inverters with RS-232 port and Watchpower Serial Protocol. It sends the collected data to the Enapter Gateway and Cloud via secure wireless connection. The RS-232-MPP Module is based on Enapter RS-232 Module.
