It depends how you use the property and how much generator noise, fuel, and maintenance you’re willing to live with.
A smaller system plus generator can work when:
- Weekend or occasional use — you arrive to charged batteries and run the generator rarely
- Occupancy is light and predictable
A full off-grid system makes sense when:
- You live there full-time or for extended stays
- Guests or Airbnb rotation won’t accept power rationing
- Resale value matters — a complete system is an asset; a minimal setup often isn’t
100UP specialises in generator-free normal operation. If a generator is included, it’s emergency redundancy — not a weekly crutch.
