Measuring MicroGeneration From Home PV Solar

Other Hardware Sensors
1

I have a six panel PV which does not feedback into the electricity network but does generate electricity as we use it. There is also no storage option.

Right now I am using a commercial product called GEO Solo II which takes an LED pulse signal from a Landis and Gyr 5235B Single Phase Pulse Meter. The GEO takes the LED pulse and converts it to a remote display.

I was curious of a project using the Arduino which could achieve the same and perhaps integrate with Home Assistant and/or a cloud service to record and monitor the Solar regeneration.

Thanks

What is displayed ?

Energy being generated in kW.

Sounds very plausible. Best to get something with WiFi capability such as an ESP32 or even a ESP8266 if you're just monitoring a flashing LED and passing the data on.

It should be easy to count the LED flashes. Even a humble light dependent resistor would be good enough if it can be attached near the LED

Presumably each LED flash indicates the use of a certain amount of energy

looks to be 1/W from the data sheet

Hi ElProblemo,

I designed and constructed a kWh meter pulse counter for my micro-PV system three years ago. It is still running 24/7 !

Are you aware the geo Solo II already monitors and records performance online, and can download a record of readings to a .csv file?

The energynote service is no longer available - geo (Green Energy Options) : geo (Green Energy Options)

Yes thanks. Seen that but doesn’t integrate with Home Assistant unfortunately. I’ve lost the internet bridge too which doesn’t help
