How to Choose Parallel Generators
-
Match Wattage to Needs
Start by identifying the total wattage you require. The GENMAX GM9000iE delivers 9000W, which suits whole-home backup when linked. For lighter loads, the Pulsar 2300W provides sufficient power for camping. Ensure your chosen model meets your peak demand. Linking units doubles output, so verify the base unit handles half the load comfortably. Higher wattage models often weigh more, so balance power needs with portability constraints for your specific use case.
-
Verify Fuel Flexibility
Dual-fuel capability offers backup if one fuel source is unavailable. The BILT HARD 4500W and Westinghouse iGen12000DFc run on gasoline or propane. This flexibility is valuable for home standby or extended camping trips. Pure gas models like the Westinghouse iGen2550c are simpler but rely solely on gasoline. Choose dual-fuel if you want versatility, or stick to gas if you prefer straightforward operation without managing propane tanks.
-
Consider Weight and Size
Parallel setups often involve moving two units. The Westinghouse iGen2550c weighs only 40 pounds, making it easy to carry for RV camping. In contrast, the GENMAX GM9000iE weighs 259 pounds, requiring a cart or two people. Measure your storage space and vehicle capacity. Smaller inverters fit in tighter spaces, while larger units need dedicated garage or shed areas. Prioritize lighter models if you frequently transport power to campsites or job sites.
-
Check Start Mechanisms
Electric and remote start options add convenience for heavy units. The Westinghouse iGen12000DFc and iGen5000DFc feature remote start, allowing you to power on the unit from a distance. This is helpful for home backup during storms. The GENMAX GM9000iE uses electric start. Basic models may rely on recoil pull. If you have mobility issues or prefer ease of use, prioritize units with remote or electric start features over manual pull starts.
-
Prioritize Safety Features
Carbon monoxide sensors are critical for indoor or enclosed space safety. The BILT HARD 4500W, Westinghouse iGen5000DFc, and AMERISUN 4500W include CO sensors that shut down the unit if dangerous levels are detected. This feature is essential for home backup or RV use. Models without this sensor, like the Pulsar 2300W, require strict outdoor placement. Always verify safety certifications and sensor inclusion before purchasing for enclosed or semi-enclosed environments.
Frequently asked questions
Can I run two parallel generators at the same time?
Yes. Parallel capability allows you to link two compatible units to increase total wattage. The BILT HARD 4500W and Westinghouse iGen12000DFc support this feature. This setup provides higher output for heavy loads. Always verify that both models share the same parallel protocol before connecting them.
Do parallel kits come included with the generator?
Not always. The BILT HARD 4500W requires a separate parallel kit purchase. The GENMAX 9000W uses a separate parallel cord that may also need to be sourced. Check the product specifications or verdict to confirm if the necessary cables are included in the box.
Which parallel generator is best for RV camping?
The BILT HARD 4500W is the top pick for RVs. It delivers clean power and includes a CO sensor for safety. The Westinghouse iGen2550c is a strong budget option for lighter loads. Both models offer parallel capability to expand power when needed for extended trips.
How much weight do I add when linking two units?
You must account for the combined weight of both generators. The Westinghouse iGen5000 weighs 106 pounds, while the lighter Westinghouse iGen2550c weighs just 40 pounds. The GENMAX 9000W is significantly heavier at 259 pounds. Plan your transport strategy based on the specific model weights.
Are inverter generators safe for sensitive electronics?
Yes. Inverter technology produces clean sine wave power. The Westinghouse iGen5000DFc and iGen2800c are designed for sensitive devices. They provide stable output suitable for laptops and medical equipment. The parallel feature allows you to scale this clean power without compromising safety or device integrity.
Can I use dual fuel generators for parallel setups?
Yes. Dual fuel models offer flexibility with gasoline or propane. The Westinghouse iGen12000DFc and BILT HARD 4500W support parallel connection. This allows you to switch fuel sources while maintaining expanded power output. Ensure both linked units are dual fuel compatible for seamless operation.
What is the lightest parallel generator available?
The AMERISUN 2500W is the lightest option at 39 pounds. It is ideal for portable camping needs. The Pulsar 2300W weighs 47 pounds and also supports parallel expansion. These lightweight models allow for easy transport while still offering the ability to link units for extra capacity.
Do parallel generators have remote start features?
Some models include remote start for convenience. The Westinghouse iGen12000DFc and iGen5000 both feature electric and remote start options. This allows you to power on linked units from a distance. Check the start type in the attributes to confirm if remote control is included with your chosen model.
