there are some users in our german pv forum who have this inverter, as far as i know they run very well. but i cant say if it is communicating well with the diy bms because nobody of them use this bms.
in theory it should run. stuart is also communicating with his inverter via pylontech canbus.
the 12kw deye has a idle consumtion of 90w if this is important for you, this 90w adds to your consumption 24h/7.
Many thanks for your feedback - much appreciated!
Unfortunately, single phase is not an option regarding the requirements and the existing distribution and cabling.
May I ask where the 90W idle power value comes from? Can’t find this in any Deye specs sheet. Is this from the experience of the German users you mentioned? Surely - wasting energy - especially in idle - is not in anybody’s interest. I think we are all here to achieve the opposite. On the other hand, what does idle in case of an hybrid inverter truly mean? Ideally it is generating power during the day and delivers power through its batteries at night (at least for some hours). So not long in a true idle state.
Without a battery, my current inverter switches down to just a few W when voltages are longer below the min required. When running, it takes a minimum of 105W for itself regarding my own measurements. so 90 W would be at least in a similar ballpark.
so this is then the idle(or on) consumption of your inverter.
i have a sma sunny island single phase, this one has 25w idle (or on) consumption it ads to my consumption on top, i have measured this.
maybe this is diffrent if no battery is connected, idont know. dont have a grid connection, i am offgrid.
Hello @stuart,
The configuration values (The multiplier to calculate the offset between the measured value and displayed value) was not lost. I could get it back from the Web GUI.
As per your comment, I reflashed the module and now it’s working fine. I will see if it happens again and will let you know.
Appreciate your quick response and support.
Thanka a lot.
We´re facing the issue of not being able to manually entering the right value of the Calibration multiplier.
Issue description:
I´ve got a cell that is not willing to accept it`s manually measured voltage.
I´m entering e.g 3.292 Voltage into the Calculater → Press Calcutlate
And than I´m ending up with a value higher than 5,0000 in the Calibration Multiplier.
So logically the BMS is not accepting the value.
Alltogether I can´t change one specifiy value set of the batterie.
Tries without outcome:
Changed the modules 3 times
Changed the modules before and after the issue module
Latest software is installed (todays release!)
Reseted everything several times
I got really badly stuck and please ask for ideas to solve that issue.
If we start to unattach the modules from top number downwards the problem with the wrong displayed voltage is shifting WITH the modules down until we reach number “0” (1st module/cell).
When i first built my v4.4 modules i accidentally left off D1 (the voltage reference) AZ432ANTR-E1.
They exhibited the exact same erratic symptoms.
When i say I left off … it was really JLCPCB didn’t have them (nor attiny) - I added the tiny but forgot the voltage ref.
Also make sure you reload your browser - i have on occasions had trouble doing updates to the controller/modules until i reloaded my browser - no error message … just doesn’t work - i haven’t debugged why but believe assume stale cookie.
If it is, it’s the first time it’s been reported in over 5 years! Either way, I’m happy to fix and bugs when found.
I’d be surprised if it were a code issue though. The modules are electrically isolated from each other. They are in effect autonomous, they have their own CPU etc.
All the controller does is ask each module for it’s voltage readings.
In the 2 years I have had this system running, there have been two times that one of the modules has started to go bad, I replaced the D1 and so far. Carlos, from what you describe, it sounds to me like a hardware problem, some component of some modules or of the controller has degraded, it is not frequent, but it can happen
I also recommend that you carefully review the communications (even reviewing the RX TX soldering in each and every one of the modules) and of course the quality of the communication cables
the wait is over , on friday i will receive 57 attiny 1624 purchased directly from Microchip Tecnology . I am looking forward to receive them and test my prototype of 16 modules
