I am specifically asking since Off-Grid (when the Grid is Not present) has a lot of additional Challenges: - Startup of big Motors/Loads (transients) - Harmonics (voltage harmonics are OK-ish I'd say based on what I could seed from time to time on my Eastron SDM630 Meter) - Response withing...

Uhm OK ... Can you please confirm you are running OFF-Grid ? I just want to be sure (I asked many questions in my previous Posts 😅 ).

@houseofancients However, the Firmware that our Facebook User Group shared online is of the following Versions: - MCU1-3PLV-Ver1001-C037-CK.bin - MCU2_SG12KLP3-V200x-1144-1122.bin You had (Sunsynk) Version 1150 main and c042 for lcd. So it looks like it's NOT the latest version that my...

I actually found that the Solar Group where I bought the Inverter had its own Dropbox share with the latest Firmware (and also a few older ones). And apparently the Update is done via Webserver (similar to an ESP32 I guess :ROFLMAO: ), so I don't need to use a Windows Laptop. However the...

I had sized for the worst case that I probably will never have. Each Inverter: 120mm2 / Fuse don't remember (I think it's 1x Class T 320 A or something + 1x gS maybe 400A + 1 x gG maybe 250A, not deployed yet, so subject to change) Each Battery: 50mm2 (next generation battery scaled down to...

So 1150 main , c042 for lcd, you said. And it's a Deye SUN-12K-SG04LP3-EU you are running, correct ? I am still worried about that Spark that I heard yesterday during the F18 event: https://diysolarforum.com/threads/bonding-multiple-deye-12kw-inverters-in-off-grid-mode.70969/post-1071155

Uhm ... I am not using the Wifi Dongle. I am pretty sure I saw somewhere some screenshots where you use a Windows (:rolleyes: - I am only using GNU/Linux nowadays) PC to connect and upload the Firmware though. But really, every Person has to send them a Request in order to Update ?

Sorry if the question is stupid but how do you Upgrade ? And where do you get the Firmware ? What are you currently running Exactly ?

I am mainly using to monitor data at the moment. I forked the original Project, added a bunch of Off-Grid Sensors to it, and made it more modular. https://github.com/luckylinux/esphome-for-deye The Apparent Power is not really working though, Deye's RS485 Register must be off ... Not a huge...

Well for an Inverter type Heatpump, sure. I also see the same. Although the lights flicker when the Microwave is turned on or Finishes cooking :ROFLMAO: . I don't think it can handle a "Normal" e.g. Asynchronous/Synchronous Motor without a Soft-Starter (those typically take 5-10 times the...

Can you please give me some more details about it ? - Are you running Grid-Tied or Off-Grid ? - What about "Improved MPPT" ? I'm pretty sure I saw lots of Power Fluctuation (cannot really tell if it's the Sun being behind the Clouds for a while or what). Also the Fans keep ramping up and down...

I tried to approach him for some customizations, if he could make it open source etc. Said no. This project is very interesting. I had to learn a lot, but it's all worth it. Approx 30 EUR for the M5Stack S3 Lite (ESP32-S3) + the Isolated CANbus base. Forget about the 200$ + that the Peter Board...

Well pros and cons. One Inverter less means also: - MPPT number of Channels is reduced -> Less Solar Power/Energy Production (unless you have lots of MPPT Channels to spare so you can transfer them to the other Inverter) - Less ability to cope with "High" Load Steps

To be honest I'm running a VERY old version of the Firmware (unsure now ... I think I got it at the Beginning of 2023 but it's still running 2022 or even 2021). BUT you know what they tell you ... You know the Devil you have, you don't know the Devil you get. And then I don't know if I can...

If he's in Off-Grid mode he cannot do the "trick" of dynamically switching the Battery Off. That would be the biggest Power saving. Similarly, you cannot turn them off via Modbus, without causing a Trip. And for Off-grid that's also not an option. I saw some Posts on GitHub where I forked my...

I think you are confusing with the AUX/Generator/MicroInverter Port. There I think it's only rated for 50% of Rated Power. But I think there is definitively a lower Rating in terms of Peak (Inrush) Current on the Load Port, at least from what I could understand by looking at the label, although...

I suggest using BMS Communication. I also thought that it wasn't needed but: - You might hit OVP all the time (I had 5 times per day quite regularly unless I monitored constantly on HomeAssistant) - You might never go High enough for Long enough and therefore you could suffer from an Unbalance...

That's what I am doing with 3 of them in parallel :) . Off grid only, everything is connected to the Load/Backup Port (a big UPS basically). I had some mishaps yesterday not sure why though ... I was getting lots of F18_AC_over_current_fault_of_hardware, F41_Parallel_system_stop as well as...

Uhm difficult to tell yesterday was a bit of a mess with something like 20 trips. First checked network connectivity that is also sketchy inside the garage apparently. And of course when I put back the Esp32 which I had to flash using usb, I connected it to the inverter but the USB cable that...

I just (by accident) "tested" this. The ESP32 Rebooted within 15 seconds of losing connection to WiFi / API / MQTT. Not 15 minutes ...

@Sleeper85 , @MrPablo : Somewhat unrelated (and maybe obvious to everybody except me ...) I tried switching a Test HomeAssistant Instance (basically an empty one where I just setup some MQTT entities logging) for test Purposes. I converted the SQLite3 Database from this Test HomeAssistant...

I've seen worse requirements at full-time jobs trust me :rolleyes:. Anyways I really have to hurry up finding a new Job now :( .

It seems more expensive than what I / @upnorthandpersonal use 😅 . Emerson Charger 48V 3000W around 80-85 EUR each with interface PCB included (you MUST contact Seller prior to ordering and remind them that you want the CAN Pads exposed, i.e. the "old Style PCB")...

Around 70-80% of Rated Power according to their Datasheet (and which Version of the Datasheet you are looking at IMHO) for 120VAC nominal. But then if it's more like 120VAC - 10% due to grid/voltage drop/etc it's going to be rather 60-65% of Rated Power ...

If you are grid connected this means that you also need to set grid charge (or forced grid charge) parameters.

Are you sure it's a BMS triggered disconnect and not the Inverter Thresholds for Shutdown / Alarm / Warning based on Battery Voltage ? Cannot remember what I have on the Deye now that I enabled BMS communication, but before I for sure had a Shutdown Voltage, a Warning / Low-Battery Voltage as...

You can connect multiple BMS to ONE ESP32 via BLE :oops::oops::oops::oops::oops::oops::oops::oops: ?

Wow, that's MUCH faster than I expected. But how exactly do you want me to test on the same Atom S3 Lite ? I don't have a wired connection ...

Right now 2 packs. 2 new being built. Space for 8 or maybe 10 in the garage. Why should there be a limit? Bms master should just give a high level overview to the inverter. Or are you thinking about bms master internal CAN/RS485 registries to store the data to process?

Pylon or Pylon+? Are you telling me I will habe problems hitting 100 kwh 🤣? IIRC when I was going through the rs485 registries for the Deye I also remember battery 1, battery 2,... But then again in case of multiple batteries the inverter shouldn't really care... The Esp32 master can just...

Are you sure you have ENABLED a setting on the inverter side, in case BMS (ESP32) communication stops ? It seems a bit weird that it didn't trip the inverter when you rebooted the Atom S3 Lite. On Deye that is BMS-Err_Stop- Otherwise in case of communication loss it will go full power (max...

OK, sorry, I didn't know that. Did you talked to him directly or just made that GitHub Issue ? Maybe it slipped through so many other issues, that's why I thought you could have pinged him directly and maybe he could have helped diagnose the problem a bit better since he has quite a bit of...

I suggest you tag @syssi in a message on your GitHub issue: https://github.com/syssi/esphome-jk-bms/issues/477 He has helped many other people debug issues giving indications how to run commands etc. The project by @Sleeper85 is leveraging the syssi code for JK BMS <---> ESP32 communication...

That was my point :) . Maybe he simply didn't configure Home Assistant correctly, therefore the Home Assistant would not establish an API connection to the ESPHome and the ESPHome device would reboot (since it didn't receive any signal that Home Assistant is up), just like it's designed to do...

Just to make sure ... One thing that caught my attention. In the YAML file do you have this ? api: If you have it and you did NOT add your ESPHome device to Home Assistant (Settings -> Devices and Services -> Add Integration -> Search for ESPHome -> Click-> Put the IP address / hostname ->...
