DIY Bi-directional DC Energy Meter for Solar Battery System

This video shows how you can DIY a two directional DC Energy Meter that measure input and output power. Most of the commercial DC Energy Meters are unable to measure reverse power. This DIY DC Energy Meter not only simple to make but also can measure reverse power. The import and export powers are separated thus it is suitable to be used for Solar PV Battery System.

thx for the video. The white wire of the YHDC sensor Vref is not connected ? regards

[@gulshan0799]

I want to Ask two Questions :
1. Will the wattage of the resistors affect the accuracy of voltage reading in Arduino or specifically what wattage of resistor should I use ?
2. Can i use Acs712 5A current Sensor in place of CT current Sensor ?

[@vaibhavxyt]

Is this ct sensor support nodemcu/d1 mini with esphome,tasmota

[@solarduino1374]

Hi, this is just another regular sensor that supports most micro controllers like arduino Uno and nodemcu. For display platform like blynk, esphome & tasmota, you need to know how to communicate between micro controller and their server. Hope it explains.
