I'm waiting for batteries, if the inverter will end up working I will open it up to check the pinout on the PCB.
I just checked with my hobby osciloscope,
8 as GND:
1 as GND:
Seem to work with standard pinout, just strange voltages when measuring.
I've got POW-HVM3.2H-24V-N, still waiting for the batteries, so testing it with benchtop power supply.![IMG_20240321_183427](https://github.com/odya/esphome-powmr-hybrid-inverter/assets/3867507/58914744-0c52-46ea-b2b8-839e73ff5d40)
I'm checking the RJ45 pinout on my bench and I'm getting different outputs than from the diagram provided.
White green (1) is GND Brown (8) is + VBat 24 V Blue (4) is + 13.2 V
or at least that's what my multimeter says. Don't want to remove the top cover because of the tamper seal to check for the RJ45 board.
