Does the CerboGX (v1) run cooler / more efficiently on 12V than 48V, particularly when it comes to running many (10) USB devices (ve.direct - USB)
I suspect it’s using a linear regulator and not a DCDC converter internally, so combined with 3.6 runs very hot and then slow.
I run my Cerbo GX on 48v. It’s pretty hot in certain places. I can easily find the hot spot with my infrared camera.
Testing with IR camera on 48 and 12
With 12 it wont even boot up.
7x mppt w USB ve.direct adapter
1 x usb vedirect for phoenix inverter
1 usb gps
1 usb BT (for temp sensors)
1 usb mk3 for second inverter
2 x ve.direct
1 ve.bus
1 ve.can
1 touchscreen 50
Time to test with powered hub
I was going to say probably a good candidate for multiple duppa.net usb to four port ve direct adapters and cheaper ve.direct cables, but powered USB hub should help.
