The Wi-Fi communication module for the ESB and HPS series inverters is a device that allows for monitoring the operation of the inverter. It acts as a communication gateway between the inverter and the monitoring server. It connects to the inverter via an RS232 cable, collecting operational data from the device. Communication with the server is conducted through the local WiFi network via the user's router. The collected data is transmitted to the monitoring server WWW. The monitoring server aggregates operational data and information regarding the inverter's status in the system, and also allows the user to monitor the status of the PV installation through the control panel.
