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...
