Energy Pass-Through Meter

Energy Pass-Through Meter As shown in photos Includes: PZEM and current transformer, ESP8266, black enclosure, and electrical connectors. It was previously used to measure solar panel power generation every minute, with values sent via Telegram messages every fifteen minutes. In good condition. Requires reprogramming, as the existing firmware is customized; only the hardware is for sale. Reprogramming can be performed using Arduino. I have three complete sets. Listed price is per fully assembled meter, excluding programming.
