Es gab zu der Zeit als ich das Video gemacht ein update welches den Verbrauch von 100 auf 50 Watt senken sollte - das war zu Hochzeit des Dieselskandals und entsprechenden Update für Auto... Es wäre eine Variante, die Anlage extern abzuschalten. Müsste man programmieren. Innen drin gibt es einen Sicherungsautomaten. Den könnte man durch einen Schütz ersetzten und diesen über eine Uhr steuern. Oder einen Raspi. Aber ich vermute, hier liegt ein Hardware-Problem in der Leistungsseite vor und das kann man nicht mir Software weg-patchen.

@@mxsteini Also bei mir in der App werden die Life-Daten relativ in Ordnung angezeigt. Gelegentlich entsteht ein Netzbezug von 3W bis 75W bzw. meistens 5W bis 30W, obwohl der Akku voll ist. Das liegt aber glaube ich eher daran, dass die Last schwankt und es dadurch immer kurz zum Netzbezug bzw. zur Einspeisung kommt. Allerdings weiß ich nicht, ob die App das auch korrekt angezeigt. Bei mir gibt es auch Netzbezugsspitzen von manchmal 200W, während der Akku gefüllt ist. Allerdings sind diese sehr kurz und kommen evtl. 3 mal am Tag vor. Ich denke, dass das z.B. an dem Einschalten von großen Verbrauchern liegt und der Schwankungen, die dann auftreten. Der Speicher oder die Wechselrichter sind da halt bissl träge. Ich bin leider neu in dem Thema und kenne mich nicht ganz so gut aus. Laut App sieht es also bei mir ganz in Ordnung aus. Kann natürlich sein, dass die App nicht alles wahrheitsgemäß anzeigt.

Habe Mal im Portal von Alpha ESS geschaut, weil es da ein paar mehr Werte gibt. Der Netzbezug für das Laden/Entladen der Batterie betrug im Jahr 2022 105kWh. Das sind bei 40ct./kWh insgesamt 42€. Falls die Daten stimmen, geht das ja eigentlich klar.

Talk not about that is untrustworthy. Senec has their values in their datasheets.

Hallo Kai, 2,5 Megawattstunden im Jahr - ist ein korrekter Verbrauch für eine 5 köpfige Familie.

Hallo Kai, 2,56MWh sind umgerechnet 2.560kWh. Das ist sogar ein recht sparsamer Wert für eine 5-köpfige Familie.

Sounds like they fixed their issues. Congratulations. My senec is like this.

@@mxsteini Do you still have your system? And the energy loss is it still a problem? My in-laws has the same system and I try to help them change a fit of their consumption from low price at night to day evening. Charging from grid. In Denmark we pay the Nordpool price with the electricity meter read each hour.

Lieber Waldemar, ich weiß nicht, was der Kommentar soll. Auf verschiedenen Ebenen ist er einfach nur hohl und frech. Und zur Belehrung: Mir geht es vor allem darum, auf ein schlechtes Produkt und eine schlechte Firma hin zu weisen. Wenn Du eine Gegendarstellung oder Lösung hast, lass es uns wissen - ansonsten halte die Klappe.

Hi Thomas, i was talking to them a long time. Last summer the battery was deinstalled. The problems with this battery could not be fixed by support. Only has replacing. They offered me an extra battery for a special price. The condition was: Delete this video and never ever do it again. The reason for being the only one with this kind of video is, that most people oversize their battery. I was talking to a energy Consultant and he said this self consumption is peanuts. So, if you are willing to take this peanuts ...

@@mxsteini did you discover whether you had a faulty unit, or is 138w 'normal' for these systems? I would not be happy with this standby consumption, even on a setup with 5x the capacity. I'm moving towards the idea of going with GivEnergy. They claim less than 5w standby consumption

@@thomaschilds8781this is the normal consumption. The update they installed didn't work anyway.

Good for you great diligents The company should upgrade this current model And tell the truth about consumption of that battery I hope when you contact them they realise this point I would now know through you never to get this battery !! Thank you

Go to senec - they need out of the box 20w without a noisy fan.

Well, as germans says: Der Glaube stirbt zuletzt. (stupid german phrase for: don't believe it) They installed an update on my battery which would fix that high consumption - but didn't. That, my friend, reminds me on the german dieselskandal. But as you wrote 68W is crazy high. * Senec Home 2.1 promised 20W * Solarwatt promised < 10W

@@mxsteini If this power consumption is not due to any durability reasons: yes it is high

Sorry, no news here. But if alpha ESS doesn't answer your question, don't touch. The reason why my issues are not published in the manual is obviously. The web interface look nice - must feature are working as promised. Don't try to stretch it over a 4k display. I sent them a css-bugfix but they said it is already optimised for 4k (no more to say) The UX of the ticketsystem is a little bit weird and you have to search a little bit for the answer link. Once they closed a ticket without a comment. Once the ticketsystem didn't work Once the ticketsystem ate my screenshots The android app is working - but "ugly as the night" (german phrase). The app internal ticketsystem can't render the HTML-text which ist produced by the backend. So the HTML-tags are displayed as text and without line-break. The battery (smile b3) has an aux-port. I never figured out for which reason. The system has no API I didn't found any information how to connect that battery to my house automation. The question was not how connect: The System itself has no meaningful function and in lag of an API I couldn't use IFTTT to do anything. It's just a battery - it is working: Secure lower threshold: 200W (it is switching far below - but not stable) Powerconsumption: 138W Conclusion: Hardware is bad, Software is bad.

@@mxsteini Hallo Michael (ich hoffe dutzen ist ok), ich bin beim surfen über folgende Seite gestolpert: www.bastel-bastel.de/blog/?p=1880 Hier wird gemutmaßt, es wäre evtl ein mini PC verbaut. Dies könnte einen Teil des Stromverbrauchs erklären. Aber das wären mMn maximal 50 Watt. Was denkst du? Gruß Heinz

Hi Christian, I know that I polemized a bit and I shortened some facts. 1. The bms needs 138w not 100w 2. You're right with 0.11 euro but 3. The high consumption forces more load cycles which damages the battery 4. Alpha ESS by themselves doesn't help or correct me at all. Instead the made me an offer for all second battery to a low price with the condition 'never ever do a video like this' 5. Senec needs 28w 6. Solarwatt runs below 10w (I can't use them in my setup) 7. BYD is below 50w So yes, I shortened a bit. There is no reason buy that device not to talk to a company that gives software updates like volkswagen.

Hi Christian, here is the correct calculation In one year the battery need 1208.88 kWh/year (138Wh) At autarky of 75% * I loose 99.73 € because I'm not selling them (1208.88 * 0.75 * 0.11) * in addition I have to _pay_ 75,55 € while the battery is soaking from grid! (1208.88 * 0.25 * 0.25) That battery costs 175.28€ each year!

I heard good things about BYD - but I don't know if they're true. I found a datasheet for some sunny island in the web that promised a selfconsumption about 20W or so. I haven't done any deep research on other systems.

Hi Chris, sorry for late reply. I didn't found something detailed about the BYD-boxes. It is hard to get technical data ... The good news is, that I can give that alpha ESS crab back. In the next step I will purchase a senec.HOME 2.1. The selfconsumption is at 28W and the lower switch theshhold is at 70W. This values will bring me trough the night.

I don't know if that device can be used in an off grid system. But I think you to store your energy and not want to waste it by running a fan and bitcoin mining machine (or what ever they do!) If you run that device in a grid, it uses power from the grid to prevent deep discharge (They never had the idea to switch take the battery from the grid). Look at these screenshot. Always 0 to 6 am. cloud.wirsteins.de/index.php/s/gAQc2KZXW2TaGJR 1 .The Device take power from the grid to prevent deep discharge. In january they installed an update (after complaining much) which reduced the standby consumption. 2. On some days (2020-02-16) there is a massive discharge like a knee in the early morning. I ask for that in a ticket. That was closed without answer! Thanks for good support. Conclusion: Do not believe in them at all.

I don't have any idea. And I cannot recommend alpha ess as company. Their datasheets are incomplete about this issue and they did not talk to me about this thing. The only thing they did was to offer me a second battery to a special price with the condition "never ever do a video like this" Look for another company - there are many. Today I would try a DC-coupled system. PS.: They installed an update with reduces the power uasge. 1. This reminds me to the german diesel scandal 2. It doesn't work

Hi Conor, sorry for my late reply. No, I have no glue which component is the gangster. Maybe they running a cryptomining software ... Yes there is a cooling. The Fan is running 24/7. Even the battery is empty and the sun is down! I want to emphasis 2 points: 1. the installed an update, after long complaining, which shoul lower the selfconsumption by 50% 2. the update didn't work I belief that they're trying to sell their last-year-development.

Thanks for your feedback. 138w is the value in the app. I used 100w in my calculation because of 2 reasons. 1. it easier to understand because the values are smoother 2. All of this moneythings are a mixed calculation and I tried to be a little bit fair. The main reason of this video was, to come in communication with alpha-ess an other users. But: Alpha-ESS is not interessested in talking anyway. They just want to sell their misconfigured devices. Think about this: After 10 years in developing this kind of device they didn't had the idea to switch it into standy if the battery is empty IN THE NIGHT. Instead of this, the device is producing grid-request to prevent deep discharge. So all of you guys out their: Do not buy Alpa ESS SMILE B3!

Dear Claran, I'm happy that a least one could learn from my experience. Next time, I would prefer a DC-coupled battery which is directly integrated in the PV installation.
