I interpret it as difference to a reference

AFAIK there is a minimum price level agreement. Tax stuff is so complex and different per country... I am not aware that is it free, typically you have to pay tax equal to you VAT. In Germany there are several level like
So I don't think doing it yourself is worth the saving (here in DE). I am not a tax expert so please check with someone you knows
4600W is due to regulation of max 20A on a single phase (in Germany called Schieflast avoidance) - not sure if this could be changed by other country settings.
Moin Moin,
Das es oben in der Menüleiste nun einen Shopbereich gibt habt Ihr ja sicher gesehen (hauptsächlich 3D Druck relevant).
Zusätzlich habe ich noch den Logoabschnitt oben (da stand vorher immer Woltlab suite) und unten den Teilen Bereich (Knöpfe für FB, Twitter etc.) entfernt. Das bringt fast 4cm mehr Platz für content oder eben weniger scrollen.
Das regelmäßig (1-2x im Monat) neue Updates (Bugfixes) eingespielt werden brauche ich denke ich nicht extra erwähnen.
Cheers schönen Sonntag noch

Hab ich ehrlich gesagt noch niemals probiert - geht bei mir aber auch nicht.
KOntaktier doch mal REC selber - ehrlich gesagt wüsste ich auch nicht wozu das BMS die Uhrzeit bräuchte außer evtl. Logfile.
Very good - thx for letting us watch the progress and the hurdles you took exceptionally well.
Check you minimum SOC settings and capacity using the SOC discharging & voltage curve as well. If it immediately drops to a low soc a "virtual" cell has reached low Volatage and BMS reacts on it.
For SI setting see RE: Nächstes Projekt: Batteriespeicher für daheim
ah OK - my old one does not have a web interface - all via sunnyexplorer or the physical interface.
Hmm - I am blind how to export the settings to PDF?
Reagarding the Parameter for the SI I am completely lost now - I don't see any of those on my SI. I can also only compare with the sunnyportal. Sunny Explorer does not give me any annswer on config settings (need to figure out why).
@ALL: someone able to suport here?
Charging control should be at BMS - Maybe I am wrong but somewhere you can set the SI to LION so BMS is external via CAN. If the SOC displayed in SunnyPOrtal is correct your setting should be OK otherwise you would get no values.
Regarding the resistence I did not get your question.
RE: Nächstes Projekt: Batteriespeicher für daheim
is a post how the SI was connected by a user.
Asymmetric between phases? You have only one phase or? Here my current AC readout - unfortunately my SI does not answer on settings request
thick copper?
RE: Nächstes Projekt: Batteriespeicher für daheim
Could be wrong measurement or bad connection - I would monitor if always the same cells are showing the higher resistance.
All cells will reach the 4.1 - it is more about that the ones with less capacity - the BMS will have to compensate with balancing acitivity, as they otherwise would be "overcharged" - if your BMS get's hot even if cooled it looks like a lot balancing. Acceptable for the first few cycles but also to be monitored.
BMS temp is already pretty high - how is this currently cooled?
Cell 5 and 9 I would monitor the resistance
And don't be surprised if it jumps to 100% soon as the voltage is close to max.
Did you check cell voltage? If this is the first charge the SOC % might be wrong. So in case cell voltage is on higher side it would charge slower.
But the picture in sunny portal looks OK - all available goes into the battery.
I don't remember to long ago - I think my SunnyIsland and SunnyWebplatform passwords are different.
You are still connected to the grid right? So I would choose 1.
Is it not powering the house at all? What about charging the batteries or is your PV just feeding into the grid instead of charging?
The SI gets all signals from the BMS (via CAN) and the SMA Homemanager/Sensor (via LAN) measuring if you feeding into the grid or consuming. So no need to connect extra current sensors etc. to the SI.
Could provide my SunnyExplorer setting this evening (if I do not forget)
Some settings that I posted before:
I only did a full charge (let the BMS balance) discharge, fullcharge cycle to calibrate at the beginning. Since this year I lowered the balancing start voltage as it seems some cells are no longer that optimum. I need to check them individually and maybe replace some - but nmot checked yet. No problem in summer when regularly reaching 100% but winter time is a but of calibration.
