Hi! I'm trying to calibrate my Growatt SPF 12000t HVM to correctly read the battery voltage which is currently 0.5V too high. Does anyone know if there is a service menu one can access to apply some kind of a voltage offset in this particular model? A quick google search returns some...

Hi There, I'm planning on making my own busbars for an S16 48V battery and a 12kW off-grid inverter. I can see that many battery manufacturers seem to have stopped placing BMS and Balancer leads directly on the cell terminals and instead, they seem to be now placing them in the middle of the...

Hi All, Today I've received my first order from Alibaba and EVE Energy (https://evebatteryglobal.en.alibaba.com/?spm=a2700.12243863.0.0.2ce83e5fYxTya4) and it's been a complete disaster. I've ordered 16 of their new 6000 cycle 280Ah cells - unfortunately most of them have arrived damaged...

Hi All, I'm working on my first solar system and wanted to ask you to help me pick an inverter that would be able to automatically prioritize which data source gets used to power my house like this: solar panels -> battery pack -> the grid. Please note that I am not interested in exporting any...

Hi, I'm interested in purchasing my first solar battery pack (together with a handful of used 500W panels) and since I can't quite afford Tesla's PowerWall, I decided to go with a Chinese PowerWall instead :cool: . 1) I'm ready to pull the trigger on this bad boy since it comes with CATL cells...
