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

Can you give instructions on how to make a 2ac 1dc measuring device?
it works great .we added an Zero export function to the code controlling an mosfet gate, hooked up to solar panels .the output switch the fet on and off .IT tells a Chinese grid tie inverter ,energy generated is only import ,so zero export if reverse flow goes under the buffer eg. (50watts).go job 😎.
Hey, Are you able to get through the Arduino Code, can you help me with it.
yes u can have the Arduino Code
Thanks a lot broo
Good work, how much would you charge me for assembling this and sending to usa please
Hi nice project you made. I am trying to do the same on ESP32 and is not working any idea why?
can this be use for 3.5w gti inverter?
Sir, can i get the full circuit diagram on PROTEUS?
do you have the Arduino program for this, mate?
hello i used your code to do zero export for grid tie inverter with an SSR .Can u take a look at the code please .i need some help .
how to show engnery kWh ?
thank very much!
Good evening sir,
We are facing issue with coding part of the project, how to resolve it, Kindly help sir...
bro please help me how to find ac power flow direction, howto find ac current direction?
please urgent
hello! can i add blynk app?
Sir, can you also post an Arduino Code for it?
Hello sir, can i use this with Hall Split core Current Sensor SCT013?
if yes, are there any changes in the code other than changing the mVperAmpValue to 66 instead of 31.25?
i am using a 33 burden resistor
Sir I liked your project and I am working on this project, But I am facing a issue regarding the availability of YHDC Hall Split core Current Sensor HSTS016L 10A/2.5±0.625V 1%, What alternate can I use in this project.
Yes Sir, I am also a member of this project kindly suggest us ....
Hi, you can use regular ACS712 current sensor module. It works exactly similar function which is hall effect. Only have to change or modify internal coding.
@@solarduino1374 thank you sir.
@@solarduino1374 Thank u sir for this suggestion...
why didnt you use ACS712 20 A current sensor module ? wouldn't it been more accurate?
Hi, I agree with you that ACS712 module has better accuracy. However it requires more safety measures during installation & fixing as there might be safety risk especially dealing with AC power. Besides, Hall effect CT has other benefits such as suitable for higher current & more convenient without altering existing measurement circuit.
