Hello again from Germany! I was totally fascinated by todays video and pressing my thumbs for you that this time your switch to offgrid would be a success! I could totally understand your feelings going like a rollercoaster! I could follow your analysis up to a certain moment but here in germany we dont have the situation with varying energy prices so I am off grid nearly all the time. I hope that your system is now working as expected, well done again! I very much like your videos and am waiting for tomorrow!😊👍
Haha you really had me at 3-2-1... oh wait like&subscribe 😂 Love it! I still hesitate a moment every time I go to turn big breakers, there's just something about them.
Hi, In the event of a network failure, it automatically switches to backup and I use this output to power all the appliances in the house. I don't have separate backup appliances. Basically, from March to October, I am running island mode. Just the whole house is on the same distribution as when it is powered from the grid. I have 2x10kW Solax G3 + 35kWh battery in parallel mode.
My inverter worked like that before I installed my Home Assistant to the inverter after that, I seems to have those issues with it discharge current not been set up correctly in an event of a power outage. Without the micro controller, it works just perfect so I will see what I come up with. Thank you so much for your comment.😃
Thanks for sharing! I know the feeling, it was a startling situation, but in the end, persistence is an admirable value here. I am not up to speed on Solax inverters, but a UPS battery backup might work for your microcontroller, so it would not lose the communication to the inverter during transfer. Congratullations!
Thank you so much and I will absolutely try with a backup battery to my micro computer, but then I also have to see if the automation are there for it so it actually send that information to the inverter when the grid fails. Let’s see about that later, thank you so much for your comment.😊
SOLAX touch switches : We have an old Miele oven and microwave which was back then quite expensive which also has such buttons that seem to work not always. The issue is that you will have no issues at all if you have only 1 finger touching the plate or the device at all. We came behind it cause it is an oven mounted on chest height where you easily touch or grab around the bar of the door and then try to touch the switches. It will not work then. So be aware to touch the device with just finger only and nowhere else to get a hopefully better result. It took a while till we got behind the Miele secret and since then if the touch is not working it had been our fault.
18:30 - 30 A discharge current does not sound much but it depends on the world or system you live with where we usually have 48 or 56V batteries and 30 A would be about 1600 Watt but with your 400 V high voltage where 30A equal 12000 Watt, quite a lot for you. I had thought your HA system would go out of power first and could not control anything more - or you had added a ups or a step down converter from the battery to be independent from the grid which I might have missed cause with the HA automation that has become the brain of your home I guess, not the solax inverter anymore.
Thanks for sharing on your channel. I just got my solax 15kw home and I'm like a little kid before Christmas. have bought the master and slave battery as well. Out of curiosity, what do you use the GROWAT inveter for besides the solax? and does the low-voltage inveter cooperate with SOLAX?
That growat inverter are connected to my panels in the garden on the trackers. Solax only have support for 2 different strings an this is my third. Good luck with your system and I wish you a merry Christmas 🎅🏻
Maybe have a button to override grid/off-grid. Might be handy in the future in case you are not at home and any other familymember has to perform this in home assistant!🎉
@@flyingtools sometimes others need to understand the system as well. We technical people might have difficulty understanding others are not understanding all things which are clear for us.

Hello Mr. A pleasure to follow you and you have been a great inspiration. I have two istabreeze 2000w that I would like to have over my newly acquired Solax x3-hybrid 15kw. How would you connect them to one and the same system so Solax manages the power.. 1: Conveter to battery and at the same time let solax take from the battery bank? 2: Otherwise, connect the Istabreeze conveter to the solar cell ports in the Solax inveter? However, I see this can be a problem, with large fluctuations. Or the third solution, where the istabreeze inverter charges a small battery pack and from there connects it to the Solax solar connection?
Hi and thank you. 😃 The problem is the voltage, 48v. Solax lowest voltage is 160v and that’s the reason why I sold my istabreeze. I did not want to play around with that on my solax inverter together with some voltage boosters etc. Sorry, it’s possible but I do not recommend it. Thanks for asking btw.
@@flyingtools Yes, makes sense. But we have a company that needs energy also in the evening and our climate conditions are the same as yours. Not much solar energy in the winter. A step-up convector would not be helpful.
In the Solax manual page 51, they recommend running them on their own circuit for consumption. But it would be fantastic if Solax could register and administer consumption.
I have found a solution. DC to DC converter. 48v to 220. Solax have PV a range from 180v to 950v. setup is from istabreeze charge controller to 4x12v Gel battery, to charge controller, to dc/dc conveter. So Solax will not have strong fluctuations, as the batteries will ensure calm fluctuations.
Maybe you can permanently connect the Home Assistant to the EPS port. If I'm not mistaken, the EPS permanently provides a small amount of power for testing purposes, maybe that's enough. My EPS switch switches in approx. 0.1 seconds (GEYA W2R-100 II) . The home assistant could survive that too...
Hi, it is already connected to the EPS side of the inverter and I don’t know why the transfer switch will have that kind of delay. But anyway, we do not have any power outage here in Sweden at all almost so it will not be any big issue, anywayit is, of course a little irritating😅 I will try to connect a small battery in parallel between micro computer, and the transformer to help the micro computer with that small power outage that will happen in the transfer time.

Hej, såg din senaste video om att gå off-grid. Har lite input till dig angående varför man inte får göra så utan att ha en automatisk "frånskiljare" mellan invertern och nätet. Det som kan hända i ditt fall är att o strömmen går och du går över i off-grid så kommer ditt system att mata ut ström tillbaka på nätet. Detta är inte tillåtet för att skydda de som jobbar på elbolaget samt deras utrustning. Tar gärna en diskussion om hur man kan göra då jag själv funderar både på batteri som i din lösning och att stötta nätet mm.
Hej och tack för din input. 😊 Den automatiska frånskiljaren är inbyggd i denna invertern så ingen ström kan matas ut från eps sidan vidare ut på nätet. Men du har absolut rätt, det får ALDRIG finnas någon risk att spänning matas ut vid ett ev strömavbrott.

IDLE is when you don’t have power from either batteries or panels: it often happens when the battery is too low at night. On Solax batteries it happens when the battery is at its minimum SoC. I don’t know what that means with your BMS.
Yes, you are absolutely right about that, the strange thing here is that I need to cycle the Battery main switch before it starts to take power again from the battery when it once went in to idle mode. That’s pretty irritating and I have not found a solution for that yet, but I am learning to live with that.😅 thank you for your comment😊
@@flyingtools Idle is not too bad per se BUT the inverter won't accept commands via the app (or the buttons) when it is in that mode. The only command that it will accept is SYTEM ON/OFF. One can turn off the system and then turn it back on. Then you have about 3 minutes of waiting/checking where the inverter accepts commands (one could MANUAL/FORCE CHARGE). After that it will revert to IDLE if nothing was done to remedy to it. One question: do you have additional earthing (jordtag) for when you go offgrid?

hm lite intressant men kanske för komplicerat för mig :) Jag hade gärna byggt Victron systen för AC nån gång eftersom jag förstår hur DC systemet fungerar. En fråga: hur funkar att bygga ett offgrid system i Sverige? Krävs det speciella saker eller en del byråkrati? Ser fram emot flera videos!
Man kan ha det (vad jag vet) men behöver ha en automatisk "frånskiljare" för att inte mata ut ström tillbaka i nätet vid strömavbrott. Annars får du driva alla grannarnas utrustning oxå ;-)
tomasis7, Strömfrånskiljaren är inbyggd och automatisk denna invertern, det fungerar riktigt bra men precis som du misstänker så ska det anmälas att man har ett system för ö-drift med mera. Detta är dock bara ett kontrollerat test och lite kul att veta att det går.

Hej!
Tack, va kul att höra😃
Låter som du planerar en rejäl anläggning👍🏻👍🏻
Tusen tack för att du kollar🙏
👏👏👏💡
hm lite intressant men kanske för komplicerat för mig :) Jag hade gärna byggt Victron systen för AC nån gång eftersom jag förstår hur DC systemet fungerar. En fråga: hur funkar att bygga ett offgrid system i Sverige? Krävs det speciella saker eller en del byråkrati? Ser fram emot flera videos!
Man kan ha det (vad jag vet) men behöver ha en automatisk "frånskiljare" för att inte mata ut ström tillbaka i nätet vid strömavbrott. Annars får du driva alla grannarnas utrustning oxå ;-)
tomasis7, Strömfrånskiljaren är inbyggd och automatisk denna invertern, det fungerar riktigt bra men precis som du misstänker så ska det anmälas att man har ett system för ö-drift med mera. Detta är dock bara ett kontrollerat test och lite kul att veta att det går.
Way not use a powerbank for the homeassistant plc.
That’s the plan👍🏻
He is using the wrong battery!!! I'm working with Solax
And it works great with the correct settings👍🏻💪🏻
Even with neg prices you benefit from runn9ing your system ... stupid to disable
You are absolutely right, this was mostly done for testing.
