When embarking on a recreational vehicle (RV) adventure, the comfort of your living space is paramount. A crucial aspect of ensuring your RV remains a cozy oasis, especially during scorching summer months, is the efficient functioning of your air conditioning (A/C) units. However, powering multiple A/C units simultaneously requires careful consideration of the generator size to avoid power-related hiccups. In this comprehensive guide, we delve into the intricacies of selecting the appropriate generator size for an RV equipped with two A/C units.
Understanding the Power Requirements
RV air conditioners are energy-intensive appliances that demand a substantial amount of power to operate smoothly. Standard A/C units commonly used in RVs draw around 1,300 to 1,500 watts each. Given the potential need to run two such units simultaneously, a generator that can handle their combined power consumption becomes imperative. However, the challenge arises from the fact that A/C units experience power surges during startup and when the condenser kicks in. These surges can temporarily strain the generator, necessitating a power capacity that goes beyond mere summing up of wattages.

- The potential need to run two A/C units simultaneously necessitates a generator that can handle their combined power consumption;
- A/C units experience power surges during startup and when the condenser kicks in, requiring a generator with a capacity that exceeds the combined wattage of the units.
Calculating Generator Size
To provide a cushion for power surges, experts recommend using generators with a capacity that exceeds the combined wattage of the A/C units. For instance, a 4,000-watt generator might appear sufficient for two 1,500-watt A/C units, but the potential power spikes require a more robust generator to ensure uninterrupted comfort. Depending on whether you use soft starters or not, you may require a 3,000-watt generator with soft starters or a 6,000-watt generator without.

Comparing A/C Models
To gain a clearer perspective, we’ll explore the power requirements of popular A/C models from Dometic and Coleman. By examining their BTU ratings and running/surge amperage, we can better gauge the generator size needed for optimal performance. Here is a glimpse into the power specifications of some well-known models:
| Model | BTU Rating | Running Amperage | Surge Amperage |
|---|---|---|---|
| Dometic Model | 13,500 | 12.0A | 55.0A |
| Coleman Model | 15,000 | 13.7A | 58.0A |
What Size Generator for an RV with 2 AC Units? Finding the Right Power Solution
When embarking on a recreational vehicle (RV) adventure, the comfort of your living space is paramount. A crucial aspect of ensuring your RV remains a cozy oasis, especially during scorching summer months, is the efficient functioning of your air conditioning (A/C) units. However, powering multiple A/C units simultaneously requires careful consideration of the generator size to avoid power-related hiccups. In this comprehensive guide, we delve into the intricacies of selecting the appropriate generator size for an RV equipped with two A/C units.
Choosing the Right Generator Type
In your quest for the perfect generator, various options come into play. One practical solution involves combining two 2,000-watt inverter-generators wired in parallel. This setup ensures ample power without the bulkiness of a single large generator. Brands like Yamaha and Honda are known for their reliability, although cost-effective alternatives like Champion and DuroMax also prove worthy.
Optimizing Power Management
Managing power distribution becomes crucial to avoid overloading your generator. Load shedding, a technique that prioritizes power consumption based on necessity, prevents breaker tripping. Installing an Energy Management System (EMS) automates this process, intelligently directing power where needed while ensuring smooth operation.

FAQ
The generator’s power output, specifically its running wattage, is crucial. You need to ensure that the generator can handle the combined wattage requirements of both air conditioning units while leaving room for other appliances.
Yes, solar power systems can be integrated to power RV air conditioning units, albeit with certain limitations. They are most effective when paired with energy-efficient A/C units and a robust battery bank.
Start capacitors provide an extra boost of power during the A/C compressor’s startup, reducing the initial power demand. Soft starters achieve a similar result by gradually increasing the compressor’s speed. Both technologies reduce the strain on the generator during startup.
EMS units monitor your RV’s power consumption and manage the allocation of power to different appliances, preventing overloads. They can prioritize critical devices, like air conditioning while balancing the overall power distribution.
It’s not recommended, as this can lead to imbalanced power distribution and potential issues. It’s best to have a generator that can handle the combined load, or to consider load-shedding solutions.
