Hatte einer von euch Probleme beim Radio oder wlan Empfang mit #Zendure, #EcoFlow oder #Growatt #Steckerspeicher?

Da suche ich seit gestern einen Fehler in meiner Config, dabei setzt der Speicher den Wert für die täglich generierte Energie nicht um Mitternacht, sondern erst zwischen 8 und 9 Uhr zurück.
Nu gut, dann muss ich halt eine eigenen Sensor (Utility_Meter) dafür nutzen
En voorlopig laatste update na een volle maand draaien. Ik heb bijna 120 kWh opgewekt en daarvan 90% zelf gebruikt; alleen op de zonnige dagen had ik halverwege de middag teruglevering. Al met al toch ruim 45% minder verbruik. Als we uitgaan van dat een gemiddelde augustus 12% van de jaarlijkse zonuren geeft, betekend dit een bruto jaaropbrengst van zo’n 1000 kWh.
Eind van het jaar komt er een tweede batterij van 2 kWh die ik aan de P1 meter koppel, zodat ik volgend jaar hopelijk vrijwel alle opgewekte stroom zelf verbruik en niet meer teruglever.
Balkonkraftwerke liegen im Trend – leider funken viele Wechselrichter ungefragt Daten in die Cloud. Das ist weder nötig noch akzeptabel. Wie man einen Growatt-Wechselrichter samt WiFi-Stick von der Cloud trennt und lokal betreibt, habe ich dokumentiert. 👇

Presently I manage my #growatt solar hybrid inverter and batteries through a combination of the #shinephone app, the #growatt web portal, and #homeassistant
This works fine for normal stuff, although I need to manually control battery charging times to match up with #OctopusEnergy tariff I'm on of #IntelligentOctopusGo
None of this is too difficult, but it is a bit annoying to have to remember to do all the right things in order to control the combination of kit and my #Myenergi #Zappi charger to ensure charger my #EV doesn't drain my solar batteries.
So I thought I would give #WonderWatt a trial and see if this helps automate and manage schedules and IOG charging correctly.
They offer a 14-day trial, which doesn't appear to be functionally limited, so I'm able to confirm if this does meet all my needs. A monthly subscription of around $6 (not sure what that is in £ for me in the UK) isn't too bad a deal if indeed it does simplify everything for me.
Wonder Watt revolutionises solar energy management with innovative online services, offering advanced and automated battery charging solutions. Our mission is to optimise solar energy production, enhance efficiency, and maximise returns for users on feed-in tariffs. Harness the sun's power, save money, reduce your carbon footprint, and embrace a sustainable future with Wonder Watt.
I have a #growatt hybrid inverter which is the base 3.6kW unit. Attached to this I have 2 x Growatt GBLI6532 batteries, each with a 6.5kWh capacity.
Whilst that means my total capacity is 13kWh, the Growatt system only allows a depth of discharge down to 10%, making the capacity a maximum of 11.7kWh in real-world usage.
My background household load averages between 200W and 250W.
My 6kW ASHP runs somewhere between 400W and 600W for normal idle use to keep the internal temperature at or around 20C which is what it's set to.
Given weather compensation on the ASHP, the power can average a little higher on colder days and be as high as 1kW when the outside temperature is below 0C.
Whilst it is technically possible to have up to 4 battery modules connected in series, the GBLI6532 is not that cheap here in the UK, and given it's really only a problem for a handful of weeks that is why I don't intend to increase the capacity further.
