I pulled the trigger this morning on the 8kw system for a possible upcoming build. Figured at the price, it's worth the risk.

Okay, so I think I am winning. Everything is installed and working flawlessly. I have noticed that the installer of my tank system was very very conservative with the float and when the float stops the tank from filling, we are only indicating about 1980lt. So, I'll address that at some stage. The enclosure might need a little tweaking and reprinting too, but for the interim it'll do. Otherwise, I'm happy with how everything turned out. I'll monitor it for a couple of weeks and then start building one for the other tank too. Thanks for all the help - the inner nerd in me would not have been able to figure this out.

Whilst the 3D Printer is printing away, I managed to fry an S2 Mini and the only DC-DC converter I have. I honestly do not know how the dc-dc got fried, but I ordered some new ones and will update once it arrives and everything is up and running.

Awesome, I'll have to resolder a bit and hopefully we're good to go then. I'll wire it all like yours and just use an additional buck converter down to 5V for the ESP32 The trusty 3D printer is busy doing its thing for an enclosure, so once it is all done, Ill give an update.

Hi Muttley Thank you for this - Claude and I are still struggling with each other, maybe because of my very Afrikaans-like English. I've gone through the schematics and cannot figure out the reason for DC-DC voltage regulator, as both the INA219 and the DF Robot can accept 24V input? What voltage setting do you use on the 'out' on the DC-DC voltage regulator then? The 24V power supply I got have two DC outputs, so I'll use a buck converter to power the ESP32 from there, but can I not connect the INA219 and DF Robot directly to the 24V power supply? I'm a little confused And also, can you cut the cable and tube on the DF Robot shorter, or should it remain at the full 5m length?

Hi Muttley and Robbie I'll be attempting this project over the weekend, as the ultrasonic sensors are proving to be absolute rubbish inside the tanks. I have 2x ECO Slimline 2220lt tanks, but will initially only use the DF Robot solution in one tank. Problem with these slimline tanks are that they have two cylinders, which join together towards the top, so I'm not sure on which formula to use in the yaml file. Do you guys perhaps have any ideas?

Hi Regbes It's now been a few weeks since your installation. I am researching a system for our family farm (we have sunsynk installed at home, so I'm biased), but the sunsynk/deye systems will just be too expensive for our use and I have come across this post of yours. How are you finding your system so far, reliability and ease of use wise? I am struggling to find warranty details or battery details (C rating/useable cycles, etc)? Regards JP
