How to find out amount of EV charging from solar generation? I have an Indra smart pro and solar panels.

Hi. Is there a way to find out how much ev charging  is done whilst generating on solar mode? I have an Indra smart pro and solar panels.

Your charger doesn't know where the electricity is coming from because it isn't linked to your inverter. Some chargers can be set up to monitor the electricity you're exporting and divert it into the car, but yours can't. I think you'd need to link everything up to something like Home Assistant to get the information you're after.

 

Home Assistant is a piece of software that runs on a Raspberry Pi and allows you to integrate smart devices in your home. If your inverter and charger have HA integrations you could connect them. Then, with a bit of programming you could crunch the data from them to get the info you want. This isn't straightforward as HA isn't an "out of the box" system. It requires some technical and programming skills. But it could be a fun project, if you're that way inclined.

With solar PV installs you can see a variety of components:

Solar Yield ; sometimes split into load/charge/export

Battery charging (where fitted) ; sometimes split into charge/discharge

Feed In / Export (grid monitor)

Consumption 

Therefore I can see what the property consumes and where it is generated. Individual feeds inside (or outside) the property would need separate monitor circuits with ct clamps or in circuit devices to report back for recording (I have know people to do this). Without the additional individual circuit monitoring it would not be possible to see what different parts take. 

 

What about your inverter? (Control box) Does it have a nameplate on it?

It’s just if you can find the make, there’s probably an app or at least a website where you might be able to see solar generation and basic use data. Mine is LuxPower and although I have battery storage as well it would track use over the day. For example, yesterday I can see 

Showing me before sun up - solar generation (green), battery charging (blue), house consumption (orange) and grid import (red).

I can see peaks and extract any significant switch on .. for example around 9am and again at 10pm, I can see a large draw (electric shower) which is partly powered by solar (morning), battery and the grid providing the excess required. If you had something like this it might give you a degree of information about individual power draws and their source. 
There is more detail available in my web feed including power logs every few minutes which give me a good historical record as well

Hi @am84 and thanks for this. Very interesting post. I’d love more info to figure out if this is a feature idea or a question that we can get a good answer to. 

 

Can you confirm if you have the Charge Anytime add on, connected to your Indra smart pro charger?

 

What you’re hoping for is visibility of how much of your generated energy is going to EV charging. Do you have a solar app?

Hi @Tim_OVO yes  we’re on anytime add on.

it’s a question first then then an idea if there’s no such function through ovo or Indra app.

I feel It wouldn’t just good to see how much is being used/saved through the use of the solar generation. Also to keep an eye on the way it effects usage from the grid and keep and eye on how true the billing is minus the solar kWh.

no we don’t have a solar app. I wasn’t aware there were any.

@BPLightlog what would be your advice for someone with solar looking for more insight into where their generation goes? My understanding was that there are apps which can help?

 

My understanding of the Anytime app is that you’ll see how much you imported for your EV via the amount of credits added to your bill. @Dark might be able to elloborate...

What is your solar system @am84 ?

Hi have a total of 16 panels.

10 at the front and 6 at the back.

I’m not very clued up in it so not much more information for you.
