It would be best for the forum and the topic to describe the problem first.
Is it with this app and a flow possible to let the inverter âwake upâ at a certain time in stead of when the sun rises?
I know it is possible to set the active power limit to 0% at a certain time, but this will not prevent the inverter to âwake upâ, right?
I hope I can make a schedule with when the inverter may wake up and shut down (a few minutes before sunset). That way the inverter does not have to click on-and-off multiple times in the morning and evening.
Off course I can switch the inverter off manualy, by the AC-switch or the DC-switch, but I like to automate this. In a YouTube-video of âKetel Kletsâ I saw that switching it on and off mutiple times on the AC-side is probably not the best thing to do.
If I want to switch it on the DC-side I could maybe connect something in the inverter, but I donât want to loose the garanty/support.
A finger-bot could do the trick, but I hope it is possible in this appâŚ
Can somebody advice me what to do best?
I think you have a solaredge but why is this an issue for you
That way the inverter does not have to click on-and-off multiple times in the morning and evening.
Donât know if it is bad for the inverter and you still have garanty. Do you have those spikes during that time?
I have a SolarEdge SE5000H inverter.
When the sun rises, I hear the inverter switch on with a few or a lot of clicks. The amount of clicks depends on the how clouded the sky is. Sometimes it is like a pinball-machine (flipperkast).
When the sun sets, it starts againâŚ
Like this evening it is clouded. If heard the âpinballâ multiple times this evening.
I like to switch the inverter on (and off) automaticly by a schedule : for example every weekday on at 07:30 and on a weekendday on at 09:00.
Is it possible to do this with the app (and a flow)? Or do I have to put a âfingerbotâ on the DC-switch of the inverter or mount a âdeviceâ in the inverter?
Hopefully this clears what I want to realise. Can somebody advice me?
It seems that the inverter settings need a threshold by advanced flow. Assume you have no battery;
-
Make sure the export is at 0% and start with 100% or a value at your wishes after sunset + x minutes & only if the solar panels produce > 100w
-
Within the flow, start a delay of at least 10min. as interval-time, no new settings possible within this timeframe.
-
Same for sunset, set export to 0% after sunset + x minutes & only if panels produce < 100w
-
Within the flow, start a delay of at least 10min. as interval-time, no new settings possible within this timeframe.
With this the threshold becomes 100w, anything below that value is stop, re-measure after delay time.
-EDIT-
There are only technical disadvantages of putting the inverter out of commision, regardless if you do this manually or by software. The Inverter is made to be online.
Letâs see if I understand it: the sun is set, it is nighttime and the inverter is switched off. If I set âthe active power limtâ to 0% now and leave it like that, will the inverter not switch on in the morning? Or will it still start clicking?
We need Edwin for this since I refer to Growatt variables. I dont know what the âactive power limitâ does.
@edwin, if you feel confident with the advanced flow solution having a threshold with delay, would you be so kind to see which vars need to be used in the AF to make it work?
For sure you need to determine a TIME, a THRESHOLD (Solar Watts) and DELAY in the AF (flow).
Just made a sample flow for you. Note that this has not been tested or error-checked, Itâs on the fly.
Also note that this would work on a Growatt using #Solarinput and #set export limit.
when active power limit is on 0 does that help? else I donât know a solution for this , besides switching off .
I cannot set the inverter status to off. You can make a support call to solaredge how to do this.
mine is in the garage and I donât hear it.
It doesnât have to be set to unlimited.
Port 502 and ID are set in the app?
The Huawei inverter was selected in the app?
Here is some more information about the settings in the app or on the web
I would assume a test with a flow on the active power = 0 option will show. @LJ_Homey, any news?
Edwin_Biemond and Phil_Bro, thanks for your replies!
With a simpel flow yesterday I all ready set âthe active power limitâ to 0% for a few minutes (and back to 100%), but the SolarEdge-inverter did not make any click-sounds then.
As I experience it, the âpinball-machineâ sounds have to do with the switching on (and off) of the inverter depending on how much sunlight is on the solarpanels. When it is clouded (like yesterdayevening) the inverter switches off and on for a hour.
I was hoping to tackle this with the app (and a flow), but I guess it has to been done with hardware.
One option I can think of, is putting a fingerbot on the DC-switch, which is operated by a schedule. (The schedule for switching off the inverter can also be fed with a minimum amount of output, X minutes before sunset.)
Another option was mentioned on the site: [SolarEdge] Inschakelen op tijd - Duurzame energie en installaties - GoT
Here somebody was thinking of putting a switch between the DC-switch and the board of the inverter, to switch the inverter on-and-off with domotica.
Does anybody know what kind of switch I could use for that purpose, which I can control easily with the homey? It would be nice/easy to disconnect the plug from the board of the inverter and connect it the the switch.
I will try to reach the guy who mentioned the switch. If I learn more, I will post it here.
If somebody has an even better idea, I like to hear it!
By the way: yesterday I also called with the helpdesk of SolarEdge. I asked for somebody with knowledge of domotica, but the Dutch guy said he knew nothing about Homey (or HomeWizard)âŚ
He said he did not know how to tackle this âchallengeâ.
Hi,
I dont think your âtestâ with setting things to 0% and back does not proof anything. The way I see it is that the inverter receives YES or NO with a fast interval to the min operating DC power. By simply putting the NEED to generate power to 0% and wait for (delay) to check the same, should avoid frequent switching.
If you try the delay as described earlier, you will have a good test.
Happy hunting!
Phil_Bro: thank you for the flow. I think I understand what you are trying to do.
Is the â#Solar inputâ in your flow for GroWatt the same as âSolar Powerâ in W for SolarEdge?
Does this measure what the SolarPanels are generating in DC, what you use as trigger?
(Or do I have to ask this question at Edwin_Biemond?)
I think it is the same but check the app tile and read what the panels produce, it should be.
Itâs the DC side idd
my SolarEdge installation showed the same behavior in the last two weeks in March.
On days with an apparently clear sky with white clouds, I get the message that the system is throttling. (I cannot hear the sound, the inverter is upstairs in a technical room. I had made a flow a few months ago for changes in the status of the inverter
Last Sunday I had a workshop on electricity on board sailing ships. The subject of solar panels was also discussed and the angle of inclination of panels.
He then explained that at a certain angle of the sun relative to the panel and with very white patches of clouds reflection in the clouds can cause a peak and the inverter will throttle.
I think this is the explanation for the behavior we see now with the inverters. It is a safety in the inverter.
Now the sun is higher I did not noticed this behavior anymore.
oh , I try to do this at midnight maybe homey or inverter was busy at that time. can you send me a report. maybe there is still some error output visible.
e2f6f665-dc01-43b2-a8c8-30b5c1561bd9
I restarted the app this morning hoping the value would reset. So i hope it has no consequense on the report.
Thanks for the quick reply

Hi again @Edwin_Biemond and thanks again. Iâve been using the app to control my Growatt inverter for about a year now 
There are currently 2 things that look to be a bit off. One is the battery temperature which we wrote about here
The other thing is the Total Day Yeld which shows 1.7 kWh, however the Total Pv1 Day Yeld and Total Pv2 Day Yeld accumulates to 4.9 kWh. This is what the Growatt webinterface shows as well, so thereâs something wrong with the Total Day Yeld
Could you have a look at this? If so what can I do to help you out?
