Best Generator for Apartment – Buyer’s Guide

1. Standby vs Portable generator

The first thing you need to consider is whether to go for a portable or standby unit.

This largely depends on your budget, power consumption and needs!

If you have a large home or office in areas prone to outages, it’s always better to buy a standby generator. The power output is huge and it starts on seamlessly.

For budget consumers looking for backup power in emergency situations, portable generators are enough. You will have to manually get it started.

2. Wattage

Wattage plays a big role when buying home generators. If you need to power up your entire home that might include a big ton central AC and large appliances, you need more wattage. The Generac 7043 boasts the highest wattage in this list.

Small apartments can do with wattage in the range of 4000-5000. In that case, the DuroStar DS4000S and Champion 3800-watt should be just perfect.

When buying a portable unit, you need to look at the starting and running watts. Because with larger appliances, you will need higher starting watts. 

3. Reliable performance

Reliability almost always depends on the quality and performance of the engine. The models we reviewed are from reputed and popular brands known for durability and reliability.

Some engines will have weather-proof protection like the Kohler 20RESL and Generac 7043 and sometimes in-built Cold-Start technology for smooth operation in freezing conditions. 

4. Tank Capacity and runtime

Tank capacity and runtime is applicable to portable units. Anything between 8-9 hours of runtime is good enough for most apartments. The DuroMax XP12000EH has the highest fuel tank capacity with highest runtime compared to other portable generators in this list.

5. Ease of use

Apartment Generators might include the following features for ease of use:

Wireless monitoring through smartphone

  • LED indicators.
  • Electric start.
  • Dual-fuel operation.
  • Low oil shutdown.

6. Transfer switch

Transfer switches are crucial for a home generator. You don’t want to run in the middle of an outage with cords all over your home.

Standby generators usually come with automatic transfer switches to automatically restore power as soon as the electrical connection is lost. A 200-amp ATS is the best you can get.

Portable generators don’t come with transfer switches and you will have to purchase that separately. 

FAQ On Generator For Apartment

1. What can a generator for apartment power up?

Standby apartment generators can power up your entire home including refrigerators, central ACs and sensitive devices all at once. Portable generators can power up essential appliances, but don’t do so well for sensitive electronics.

2. Automatic vs manual transfer switch— what is the difference?

Automatic transfer switch gives you hands-off experience as it shifts to generators and back to electricity automatically. With a manual transfer switch, you will need to make the shift by yourself.

3. What should I buy— a portable or standby generator?

If you have a large and permanent premise with frequent power outage, get a standby generator. For infrequent outages in small homes, portable generators will be sufficient.

Conclusion and Editor’s Choice

In terms of reliability and power consumption of a typical apartment, the Kohler 20RESCL Generator is the best Generator for apartments.

This air-cooled standby unit restores power in less than 10 seconds and that’s what you need in emergency situations. The ability to install a wireless monitoring device is another great advantage of the generator. 20,000 watts is more than enough for most big apartments.

Residents of small apartments can get portable units as buying bulky and expensive standby units might not be always necessary.
