Okay, i get to have some fun designing a power box for remote-ish work.

Task:
Power GPS receiver, Starlink, overwatch camera, and maybe a radio of undetermined power

Outputs likely a mix of 12V\110V\Ethernet (POE unsure)

Main constraints:
Cheap company
Generator, light plant or other dirty electric source that isn't on 24/7
Need to output clean steady power, pure sine wave or better
Has to fit in a JobBox or similar.
Weight not a huge concern, but lets not get too stupid
Plan on 1/3 of the box for project equipment, cable storage, etc.
No power for 11-14 hours per 24H, might need to run up to 48 hours with no power. Rather not put in a timer option, but might have to consider it

Rough plan:
Dirty power source into jobbox through one plug pass through
Backup pass through for second genny option (like an RV plug style maybe so cord stays in box)
Batteries in a bank of some size to stabilize power and supply reserve power when dirty source is off
Dirty source keeps batteries topped off
UPS to clean power and run electronics at all times (generator friendly)
solar panels or another power source may be an add on later
an option to provide clean power to additional equipment would be nice. Think Laptop or something you roll up to it with.

What do you suggest?
and what am I overlooking?

Leaning towards either Deep Cycle auto batteries, or forklift\golf cart batteries. Open to other types, especially if cheaper.

Camera might get dropped, so POE not mandatory unfortunately. (Will be after vandalism\theft, lol)

UPS needs to be genny friendly. Network Management would be nice (remote)
VFI\double conversion
Line Interactive vs UPS
Power conditioner
Temp sensors for cooling fans (2 different fans\set points)
What to use for pass throughs? probably round holes cut in thin sheet metal.
 
Go LiFePO4 for the battery

Victron makes everything you could ever need for this project
