Hi,

Could you add a option to read and write the export limit? It is address F001

Thanks

yeah, will do, should be easy.

export limit is what we control or not?

By the way for your solcast, is it possible to add a flow condition so I can charge the batt with dal tarief when needed (like when expected kwh for today is less ) , I run this after midnight so prediction should be in for that day..

djfanatix commented 2 years ago

I am not sure if it is export limit or total production limit I have to try it.

I will check on the Solcast app

biemond commented 2 years ago

can you test this and see if this is what you want.

and https://github.com/biemond/solaredge.modbus/commit/80bd9ae7780b22c7404ca49af1f91bd3ff6b8dae

djfanatix commented 2 years ago

Yes I see the same.

I found some more documentation:

Can you make a flow card or a setting to change the power limit?

I think people with dynamic energy contracts can then enable zero export in case of negative prices

biemond commented 2 years ago

really that is a thing in europe. you have to pay when you do export to the grid. So you can only do this when you have batt or when it is stimulated and get paid for it.

biemond commented 2 years ago

so an enable/disable flow with. advanced power on 1 and reactive power config to 4 or for normal/enabled both back to 0 is this also a menu setting/action? which one?

if you do this on the invertor = active power limit 0 % then?

djfanatix commented 2 years ago

No most of the time you get paid to export, but on sunny and windy days, the rates are negative, so you have to pay. (or you get paid to import)

djfanatix commented 2 years ago

I found this in another repo: I think I was wrong, the active power limit, limits the inverter, that's not what we need, we need to limit export (with a meter of course)

I don't think (for my needs) that E001 has to be included.

0xE000 - 1 - Export control mode: 16bit_uint

 0: "Disabled",
 1: "Direct Export Limitation",
 2: "Indirect Export Limitation",
 4: "Production Limitation"

0xE001 - 1 - Export control limit mode:16bit_uint

 0: "Total",
 1: "Per phase"

0xE002 - 2 - Export control site limit: 32bit_float

["Export control site limit", "export_control_site_limit", 0xE002, "f", {"min": 0, "max": 10000, "unit": "W"}],

biemond commented 2 years ago

yes that looks better , I know sometimes on US or AUS you cannot deliver back to the grid.

biemond commented 2 years ago

let me 1st retrieve those and add them when they are ok.

I checked this, but I am not planning to rewrite the app for sdk 3, as it is too much work with the whole UTC timezone and crontasks thing. You can just use logic and the solcast tag and use it as a condition. (greater or smaller then..)

biemond commented 2 years ago

thanks

biemond commented 2 years ago

I need this from oct/nov

biemond commented 2 years ago

biemond commented 2 years ago

so only when you have a meter.

I think I only need to set these 3

export_control_site 5000 xxx Export control site limit

biemond commented 2 years ago

can you try this https://homey.app/a/solaredge.modbus/test/ for now only a menu item ( no flow ) and export limit fixed on 5000W
