For those unfamiliar with the Enphase Solar system I will give a brief explanation.

If you have solar panels you mostly use a, so called, string inverter. All the cells of the panels are connected in series and the DC power is converted in one single inverter to AC. The disadvantage of such a system is that, if one panel, e.g. because of shadow, produces less power then the others, the whole system switches back to that lower level. You can solve this by means of optimizers.

Another solution is to use micro-inverters. Each single solar panel gets its own inverter and the DC power is directly converted on the roof to AC.
You don't have a (larger) inverter in your house.

This system has several advantages, but the disadvantage is that it is more expensive if you have a large number of solar panels.
One of the advantages is that you can read the individual power production of each panel.

As recently the functionality of the Enphase Envoy-S has been extended and now also support the Envoy-S metered, I suggest that the software for Enphase S is extended once more so that we are able to read the power production of each individual solar panel.


In this case it will give you all the results for the individual panels.


I have made it this way with Node Red and it works fine for about 3 months now.
Would be a good idea to have this natively implemented in the Enphase "hardware".

I'm open for discussions and other suggestions.

Can you plz share your flow of Node Red
Now I run a Batch script every 5 mins but think it's better to use mqtt for it

Thanks already

Hello Arjan,

As I got another request as well, I started another thread.
Currently I'm on holiday and it is to complex to make a clear description on a tablet.

See: https://www.domoticz.com/forum/viewtopi ... 14&t=29331

It will be continued end of next week.

Can i install node-red on my synology

Hi,

I do not own a Synology Nas, but Google is your friend
If you try Node Red Synology, the your first hit is: https://www.rs-online.com/designspark/i ... nology-nas.

But if you don't succeed @waaren has wrote a dZvents script that gives the same result.

when i try to install i get this error.

npm ERR! code Z_DATA_ERROR
npm ERR! errno -3
npm ERR! zlib: invalid distance too far back

Hi,

I suggest, that you open a new topic, as your problem is not related to Enphase microinverters or to collect data of individual Solar panels, but more on how to install Node Red on a Synology NAS.
