In this buying guide, we are going to guide you on which of the features you must look at before purchasing a Generac generator.
Inverter vs. Conventional vs. Standby
First, decide which type of generator you need. If you need a generator for recreational activities, an inverter generator is ideal for you. For small or mid-size homes with not many appliances to run, go for a portable conventional generator. But to power whole big houses or businesses, a standby generator is a must.
For inverters, you can either go for the iQ Series or GP Series. To buy a portable conventional generator, there are many options available. These include the GP Series and XT Series, along with the XC Series. And for a standby generator, you can have any generator from Guardian Series, PowerPact Series, EcoGen Series, and Protector and QT Series.
Inverter generators are compact and light in weight. Due to their smaller size, they have smaller fuel tanks, but the presence of economy mode makes them fuel-efficient.Also, they make a less operational sound because of in-built special mufflers. Moreover, they produce clean and stable power. However, inverter machines cannot deliver higher power output. Also, they are expensive.
Conventional generators are bigger and heavier, but they are portable as well. They have bigger fuel tanks that give extended runtime. Also, they produce higher output power,but most of the units fail to provide clean AC power. Also, they are louder than inverters.
Standby generators are more powerful. They operate automatically within seconds with the help of a transfer switch. When the utility power goes off, this transfer switch immediately senses it and forces the generator to start and take the electrical load.
Make a list of appliances, tools, or electronics that you will power through your generator. This will help you to know how powerful your generator should be.
Generac has a variety of generator models, so you will surely find one to meet your power requirements.
An inverter generator with 3000 rated watts is enough for camping, tailgating, or even to power RV. For home usage, you can also go for a 3000-watt generator to run limited appliances. But a 4000-watt generator is an ideal choice for small or mid-size homes. For construction sites, at least an 8000-watt generator is required. And to power the whole house, make sure your generator produces more than 12,000 rated watts.
In a nutshell, power output totally depends on the number of appliances you need to power. More appliances and tools, more power is required. Fewer appliances and tools, less power is required.
Fuel Tank Capacity and Runtime
If you need longer runtime, go for a Generac generator with higher fuel tank capacity. Portable conventional generators are less fuel-efficient; thus, they have bigger fuel tanks. On the other hand, inverter machines have smaller fuel tanks because of their fuel-efficient engines that use less fuel to give similar runtime.
Power outlets of a generator also need to be checked. For camping and tailgating, make sure your generator has USB ports along with two 120 Volt AC household outlets. To connect your generator with an RV, you must have an L5-30R receptacle. To power home appliances and tools, make sure your generator has at least two 120 Volt 20 Ampere (5-20R) outlets along with one 120/240 Volt outlet.
Noise pollution has already done severe damages to our environment. It is our responsibility to limit its devastating effects. So, by purchasing a quiet generator, we can play our part in reducing noise pollution.
Inverter generators produce less operational sound than conventional portable generators. Also, there are many home standby generators, which operate without making much noise. So, it is suggested to go for a unit that has less decibel rating.
