Here are the specs : Monitoring is done via Home Assistant running in a Docker container, itself running in an LXC container on Proxmox. Most sensors communicate in zigbee, including the Linky via a tiny self-powered module. To communicate with the solar inverter, a Solarman Integration via Wifi is used. The first 4x 435W string is installed on the roof, but the 6x 400W are still on the ground for now, as the hardest part is climbing on the roof with large fragile objects of 20 Kg each and not…

One of our US-48-500W died at work. Since Ubiquiti has bumped the price and shifted the range quite a lot, I decided to repair it to keep it as a spare. I first confirmed that the PSU was the culprit by powering the switch with my lab PSU.

I didn't put much efforts into PSU placement in…
