Always difficult to have all settings aligned, remember them and keep them working. Good stuff in explaining, keep up the good work and great you are broadcasting this. Live is not always positive so you had a good thought and explained what was going on, this we learn from. Succes in being off-grid/on-grid when needed.
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!😊👍
Well done for sticking with it and continuing to record when things went wrong. I make YT videos too so I know how tempting it is to set the camera sown at times like that. Seeing you had an issue and how you solved it is much more helpful. BTW I'm going through your videos at the minute to pick up tips on the Solax inverter as I have only today got it going. Thanks for sharing.
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.😃
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.
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. Thank you for your comment.☺️
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. A simple checklist might prevent a Single Point of Failure and gives you rest when not at home and someone needs to help who is home! In the end it's a lot of moving parts and also some automations which might bite you in the behind. Good luck!
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.😊
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.
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 🎅🏻
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.
Very nice and informative video.. 👍 How far is your high voltage battery from your inveter.. What is the cable length and gauge.. is there a voltage drop? Thanks
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?
@@nicolaslaurencin6862 wow, this was interesting and very good information, thanks!!😃 This makes me understand this idle mode better. The strange thing is that it will go in to idle mode when the discharge current sets to 0 Amps. I will give you a scenario: Inverter mode: feed in. Energy price high Discharge current set to 25a. The sun sets and it will start to take power from the battery, everything is working as expected. Scenario 2: Inverter mode: feed in. Energy price low Discharge current set to 0A. The sun sets and it will start to take power from the grid, everything is working as expected until the energy prices is high and I set the discharge current back up to 25A, it will not take power from battery, still saying idle. I then need to do a hard power reset. Soc over 90%. Soc info is coming from home assistant via modbus to inverter. Inverter works in lead acid mode, and I think that that might be the issue, a software bug only in lead acid mode. Or maybe a missing massage in the modbus protocol that it is ok to start using the battery again. I’m just guessing here… And yes I have a earth rod, it’s measured to 46 ohms by a certified electrician. Probably one of the most important things in a off grid system.
@@flyingtools In your scenario 2, aren't you better off choosing Manual/NoChargeNoDischarge instead of Going FeedIn with 0A max discharge? I feel that advanced settings should be left alone if you can achieve the same results by using basic settings...
Super intressanta Videor😁 Följer dig slaviskt😜 ”Har själv ett litet off grid system 24 volt till 230v 8 gel batterier ”. Kommer att Bli 3 fas med Huawei Växelriktare.
Hi and thank you for all your interesting videos. It's there a schematics available for your Solax inverter? Interested in how your of grid connection is wired up
@@flyingtools Ok, thanks. I have looked at it a bit before as well and it seems quite strait forward. One question pops up about the ground rod. How have you solved that and where is the rod connected?
Hallo Freund, ich möchte dich um Rat bitten. Ich habe einen Sofar-Wechselrichter und möchte zwei Batteriespeicher eines Ford Kuga parallel schalten. Einer hat 14,4 kWh und 350 V. Es gibt 7 Stück 12s1p-Artikel. Können Sie mir raten, welches BMS ich für die Verbindung mit 84s2p verwenden soll? Ich habe am Wechselrichter nur einen Eingang für die Batterie. Nun, danke. Martin aus Bratislava
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, 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.
@@MrRosentorp Vid 500v på batteriet så ger ger den 15kW jag har som Max 450v i mitt batteri vilket ger 13,5kW. Men med stöd av solpanelerna så går den på 100% om soleffekten bara är tillräckligt.

Hello!!! It steel working inESP mode without battery!!! The question is why without a battery? In our country is a different system when we connect solar panels inverters to the city grid. To date 31.12.23. we can make connections to neto delivery systems, we give power to the city grid, and in winter we can bye from the city grid (the price is 3,9 cents + VAT). These neto systems working to the date 02.2029.
Hi. I tried that now when I did this video, of camera, and I was not able to have my system running on only solar panels, but it can be different software in different countries.
@flyingtools Solax ingineere toking about different settings for Solax. Today, we are coming to our country, and I hope we have a meny answers to questions. Jautājumi, ko sūtam rūpnīcas supportam: We are an automation company from Latvia. We are working in Baltic States, and our customers need the best solutions with full automation. Can u make some WEB learning's for me, or can you send a webinar video. We tray to use Solax X3 HYBRID-12.0 G3 and 15+kW inverters and need factory support to find the best solutions for the full automation system with a) Smart Hub b) Smart Cars chargers Solax produce? c) With and without batteries (another brand and we need to use lead accid settings and upgrade inverter to new factory firmware) CORRECT? ! d) energy meter Chint with the ModBus RS 485 (we need limmit power to City grid max 11.1kW, but all another power go to home, not limited full inverter power to 11.1kW) Questions and customers waiting for immediate answers before we order from the factories: 1. ESP loads give out power without batteries if solar panels give out more 2kW of power? 2. Solax has 4DC PV inputs, but only 2 MPPT. How we can connect 3 different roofs? 36pcs (PV1 18+ PV2 18) East 10pcs (PV3) East 12pcs (PV4) West How is working this setup with only 2 MPPT. There were no roofs to the South in our customers' place 😢 3. What's the new with smart car chargers? If solar power gives meny power, then all free energy charging car wiht the smart power regulator. Hi bye Audi E-Tron.
