Frequently Asked Questions When Choosing an RV Generator
What size generator do I need for my RV?
Size requirements depend on your power needs. Generally:
- Small RV (basic needs): 2000-3000 watts
- Medium RV (with AC): 3000-4000 watts
- Large RV (full amenities): 4000-7000 watts
- Luxury RV (multiple ACs): 7000+ watts
Can I run my RV AC with a generator?
Yes, but you need to ensure:
- Generator has sufficient starting watts (typically 2-3 times running watts)
- Proper sizing for altitude operation
- Adequate surge capacity for AC compressor start
Should I choose an inverter generator?
Inverter generators are recommended if you:
- Use sensitive electronics
- Camp in noise-restricted areas
- Value fuel efficiency
- Need clean, stable power
What about parallel capability?
Parallel capability allows you to:
- Connect two smaller generators for more power
- Provide flexibility in power needs
- Share load between units
- Add capacity as needed
