General Questions
-
What is a standby generator?
A standby generator is a backup electrical system that operates automatically. When utility power is interrupted, the standby generator automatically supplies power to your electrical circuits. Once utility power returns, the generator shuts down and the electrical load is transferred back to the utility. This transition happens within seconds, ensuring minimal disruption to your electricity supply.
-
How does an electric generator work?
Electric generators convert mechanical energy into electrical energy. The most common home generators use an engine powered by fuel (such as natural gas, diesel, or LPG) to drive an alternator that produces electricity. When the generator detects a power outage, the engine starts automatically, and the alternator begins generating electricity that flows to your home's electrical panel to power your appliances and devices.
-
How long can a generator run continuously?
The continuous runtime of a generator depends on its type, size, fuel supply, and load. With proper installation and an adequate fuel supply:
- Portable generators typically run 8-12 hours on a full tank
- Standby generators connected to natural gas lines can run indefinitely as long as gas service is maintained
- Diesel or LPG standby generators can run 24-72 hours depending on fuel tank size and load
For extended outages, our service team can assist with refueling solutions.

What size generator do I need for my home?
The size of generator you need depends on what you want to power during an outage. For essential circuits only (refrigerator, lights, a few outlets), a 5-8 kW generator may be sufficient. For powering most household appliances, a 10-15 kW unit is typically recommended. For whole-house coverage including air conditioners and electric heating systems, 20-25 kW or larger might be necessary.
Our team can conduct a free load calculation assessment to determine the precise size that meets your needs. This involves listing all appliances and systems you want to power and calculating their combined wattage requirements.
-
How noisy are home generators?
Modern home generators are designed with noise reduction technology. The noise level typically ranges from 55-70 decibels (dB) at a distance of 7 meters, similar to the sound of an air conditioner or normal conversation. Our Premium Series generators feature enhanced sound insulation, reducing noise levels to as low as 55 dB.
For context, normal conversation is about 60 dB, and city traffic from inside a car is about 70-80 dB. All Darkvolt generators comply with local noise regulations.
