Hello i used the search button and this topic was already discussed, i can understand that the current measuring components in the inverter are not the best but i need to calibrate the reading via software if possible (VenusOS RP)
With no load the inverter reads -0.2A altering all the DC power readings adding 46W of loads and its really annoyng, i have some experience with linux but i don't know how i can add a +0.2A to the reading and what to edit.
I could also act on the board if there is something that can be done to calibrate it.
When the inverter was new the readings were good.
Thank you.
