  1. @Powerforum Store any good/special prices on 330w pannels?
  2. Draw.io I used it for mine. Takes a bit of time to catch how it works but after that it works super nice.
  3. The bmv is design actually to be use with lead acid based batteries by using the Peukert's law to work the state of charge of battery and discharge. With the lithium and lifepo4s busy taking over the market slowly, Peukert's law don't really work with them. A bms is Battery Management System that actually keeps a eye on every sell in you lithium / Lifep4 setup and works out the stage of charge and deside if it needs to shift volts over to other cells "active ballancing" or if there cell run away that it stop the sell from run away by stopping the charge toe the batteries and start movin
  4. If planning to 10kw, then look at the new design MLT powerstar. There is plans of it be in the CoCT new list. Just need to dubble check with @Stanley
  5. Yes, my MLT gives that info and they really close. I use say about 98% the shelly EM info if i need to check. My day to day use lines up with my PV kwh and Battery kwh use. Best is to check here : https://shop.shelly.cloud/shelly-em-50a-clamp-wifi-smart-home-automation-1#139 The SA one you mail got a bit of story behind them, you can check on mybroadband. I see takealot stocks the Shelly 2.5 but it's way over price. You can import 2 for that price. SHELLY EU got n fix rate of €35 with DHL and then you stack the box full of shelly stuff. Maybe check on the forum if some poeple
  6. I'm running mine in my inverter DB that supply the house. It uses the L and N from your supply to give it power, so it keeps eye on AC volts and Power Factor. Clamp 1 I'm running in Main AC Breaker to my change over switches and Clamp 2 I'm running on my geyser to keep a eye there. I got my geyser interlock between eskom and the inverter so dump all my extra solar to the geyser then. What nice about the shelly EM is, it's got n relay/contactor control so jy kan switch stuff on via the Shelly EM. In the settings you can adjust so if you got n load on clamp one of say 3000w, and your inver
  7. @Energy mine was in the same DHL box in lockdown with yours
  8. Other option is the Shelly EM. It runs wifi, upload via cloud so you van connect to it via app, website or log into the IP. Keeps log , hour, days Nd months and year and you export data. You can connect it with Grafana to. It runs 2 clamps and gets it's power from AC in your DB so it works Power Factor in to.
  9. Hahahahahah. Your OCD is working overtime with my posts. Jammer!!!
  10. To add what JJS where posting about, we were talking off forum allot, I had the same problem with my Microcare MPPT. When I started with my first lifepo4 bank, It will charge it full, go in float and stay on float then. If there is demand from the inverter, it will start taking from the lifepo4 bank, and a bit from the the MPPT where the MPPT must have supply the full load. It will idol like this and put a bit back in to the lifepo4 in float mode and then will idol in low volts again, till you switch it over in Boost mode again and then it will charge at full. Same story in Float it will not s
  11. Here some better photos of one of them. I think this is a lower amp version. My got FIT's on both side. @plonkster Jip. Looks like a ESP. I got the 3de bms on it's way, slooooowwwwllllyyyyy. I will open that one and take some close photos.
  12. @Louisvdw no problem. Here it is You will see there is n google drive file and everything is in there. He explains how to upload and setup all the stuff. Keep us posted if you get something running.
  13. Here is the board behine the screen
  14. Nope. The ant BMS bluetooth part sits on the BMS. The screen output rs485 that go's to the board that process all the info for the screen. I got the python script to upload to a Pi to pull the data off the bms to Grafana.
