GoodWe inverter fan holder

thingiverse

Fan holder for Goodwe inverters. Designed for GW-10K ET, but can be used to add active cooling to any inverter using passive cooling. I mounted it underneath the inverter. The holder can be mounted using 4 screws or taped to the wall. Three parts of the holder hold together using screws. I used these components: - 6 digit 7-segment display LED TM1637 (with VCC, GND, DIO and CLK pins) - nodemcu v3 board - temperature probe DS18B20 - five Noctua NF-A6x25 PWM fans (12v) - 230v AC -> 12v DC power adapter - buck converter to convert 12v to 5v to power nodemcu - rocker switch 12v - 12v female connector for the adapter The bigger hole at the front is for the display. The smaller is for the rocker switch. Temperature probe is read by the nodemcu and PWM is used to control the fans speed. I'll publish the code for nodemcu when it is ready, until then feel free to write your own.
