In case you're in the process of preparing for emergencies, planning for a way to run a work site, or you have recreational usage in mind there's plenty to think about when purchasing portable generators. To help you figure it all out from the myriad of options available we've put together the things that our team of professionals is looking for when they're in looking to purchase the latest model.
Power and Outlets
If you are looking to purchase the right generator to meet your needs the first thing to be aware of is the size generator you're looking to purchase. It is important to know how much power you will require. Your refrigerator might require 700 watts to operate however what happens if it requires 2100 watts of starting power? Be aware of the startup power needed to operate the appliance you're planning for connecting with the generator, as in addition to your "running watts" you require when everything is working.
The other aspect of the discussion is what kind of outlets you require. Inverters with smaller capacities will typically come with a few 120V AC outlets, and perhaps some USB ports. As you increase the power to 4000 watts you'll start getting 240V plugs together with additional 120V outlets. If you're considering having an electrician connect the generator directly to your power panel, you'll require an 240V plug. If you're planning to use your generator outside, make sure you choose one with GFCI secured outlets.
THD or Total Harmonic Distortion (THD and Clean Power)
If you are planning to operate electronic equipment , like laptops or laboratory equipment, the waveform is important. In general, you require the harmonic distortion to be lower than 6 percent in order to prevent damaging electrical circuits. Sometimes, it's called "clean power" or "pure sine wave" as it's an extremely stable and reliable amount of voltage. Pure sine waves are more costly and can be found on units with lower watts.
In addition, battery inverters do not have to be model with low-THD. Some emit square waves. Make sure to check the specs if think you need power that is clean.
Infrequent or Regular Use?
A majority of generators have the consumer warranty that will cover you for a number of years. In case of emergency power or recreation, any reliable model will be able to meet your needs. But if you're managing an operation that requires generators every day, you're likely prefer to look for a generator with a commercial-grade engine. It's not just an ideal fit however, you'll also have a warranty for more than a whole year instead of 60 days or 90 days. The only downside is that they're typically more costly.
Type of Fuel
Gas generators are the most popular. It is easy to find, except for the chaos that precedes and days after major hurricane preparations.
Diesel generators offer greater fuel efficiency if you're willing to spend the money for an upgrade. Additionally, you'll get rid of the carburetor which always appears to be blocked at the most inconvenient moment. If you're considering buying the purchase of a complete house generator, you'll need to look at diesel. Be aware that diesel isn't as readily available as gasoline.
A different option would be to search for an propane generator or gas generator that could be converted to propane. If you want to go for a more environmentally-friendly fuel source and don't mind that it's a bit more complex, it's another way to go.
Inverters powered by batteries like EGO's EGO Nexus Power Station and the Ryobi Power Station offer the benefit of being rechargeable via solar panels, work completely silently, and produce zero emissions. However, they're expensive, charge very slow, and will typically not provide over 2000 Watts, or even so. Apart from tailgating and camping it's not a practical choice at present.
Fuel Tank
The larger the tank, the more time it will take between refills. It's a fact. The majority of generators have an energy tank that can provide you with 7 to 9 hours of power at 50 percent load. It will run longer if you utilize less of the available power, and less when you're using more. If you have to choose between a larger or smaller tank, I'd go with the bigger. Be aware that it'll weigh more with the full tank.
There are also gas and plastic fuel tanks. The pros and cons to each, and we have both. In general, I prefer plastic because there aren't any corrosion problems associated with it (thanks to alcohol). But it's not an issue for me.
Beginning
If you are a fan of using a recoil cable on an engine, then by all means, avoid using the electronic start. However electrical start engine are great in the event that you can afford the additional cost. When purchasing an electric generator for your portable it is likely to make use of lead-acid batteries similar to the ones in a car. There are lithium-ion models that are out there, however.
Make sure you recharge your battery prior to using it. The majority of generators can be used keeping the charger on to keep the battery charged in between.
Noise Level
Smaller generators are able to avail of quiet designs. They can be quieter than standard conversations. If you're going to be tailgating or camping in a place that has generators Your neighbors will appreciate the attention.
At the point you are able to move to the 4000-watt class or greater, there's not much to be found within"quiet" class "quiet" class. The main issue is the fuel source. Diesel generally produces more noise than similar gas-powered model.
