I assembled a solar server with those parts laying around last year:

- Victron Monocrystalline Panel 90W 12V

- Victron Gel Battery 12V 60Ah

- Victron MPPT Charge Controller 75V 15A

- Raspberry Pi Zero W

- Witty Pi 5

- Sixfab 4G/LTE Base HAT

- Quectel EC25 Mini PCle 4G/LTE Module

Almost 100% uptime except for a few days after a bad winter storm, pretty neat!
