    How to Select a Portable Generator

    You should start by considering the right type and size of portable generator. Once you have come to terms with the type and size, you should thereafter consider the following.

    Portable Generator Type

    The type of the generator is the most crucial detail that you must always consider first. Portable generators are generally distinguished by the type of fuel they use. For instance, you can select a propane powered portable generator, a gas powered portable generator, or a diesel powered portable generator. Ideally, all the portable generator types may prove useful; however, they differ conveniently based on the fuel running the engine. Propane portable generators are known to be effective since propane burns clean. Gas portable generators are considered effective since they do not produce pungent odor. Diesel portable generators are considered effective since they provide continuous supply of power. Nevertheless, diesel types are known to be expensive as compared to the other two. On the other hand, propane types are not only efficient, but also affordable.

    Your choice of fuel in addition to generator type should be established by how frequent you will be using the portable generator along with the fuel available in your region. A diesel powered portable generator is most effective if you reside in a region where blackouts are frequent. Diesel powered portable generators are known to be powerful, and long-lasting; however, they tend to be quite challenging to start in cold meteorological conditions. You should consider propane powered portable generators if propane is readily available in your residential area. Propane normally burns cleaner when compared to diesel generators, and they also last longer. Therefore, your choice of generator type is mainly guided on the type of fuel used, and how easy you can access the fuel, as well as how the environment affects the fuel.

    Portable Generator Sizing

    Portable generators are normally most efficient when the load is 50% of the rated generator capacity. To properly size a generator that you wish to buy, you need to come up with a list of items that will require electrical power. You need to pay more attention to the voltage that your appliance requires. For instance, if it runs on 240V, and you plan to run it during an emergency; then you need to select a portable generator that outputs both 120V and 240V.

    Portable generators are sized with both surge and constant power ratings. Therefore, make sure that the portable generator you select provides you with enough constant as well as surge power for your specific loads. Remember, anything that involves a motor will need additional surge power during startup. You can determine total constant power by adding up all constant power loads that will be running synchronously. You need to determine the extra surge power needed for your appliances in order to calculate total surge power.

    How You Will Use Your Portable Generator

    There are several major uses of portable generators that you may have, including: emergency power backup; camping, boating, tailgating, and RV; and construction and rental. To make an accurate list of power usage, you are advised to check appliances’ labels as well as paperwork for power requirements. Ideally, the amount of electricity indicated on an appliance is normally the maximum electricity it uses. You should know that some devices have the tendency of consuming a small amount of power even when they are off. Therefore, to get the most out of your reliable power source, you are urged to unplug anything that is not being used.

    Specific Portable Generator Features You Should Look For

    1. Compact and Lightweight

    A good portable generator should be compact and lightweight. The design should be easy to maneuver as far as transporting and positioning is concerned. A compact and lightweight gen-set should be easy to throw into the boot of your van while out camping. In the event of an emergency, such as hurricane, the gen-set should be easily accessible from whatever position you would have stored it.

    1. Automatic Transfer Switch

    This switching mechanism is useful in that it senses when power goes out, and turns on the portable gen-set for virtually uninterrupted power. Once power is reinstated, the automatic transfer switch turns your portable generator off. The automatic transfer switch helps to prevent back feed into the power that could potentially lead to fatalities.

    1. Automatic Voltage Regulation and Instant Reset Circuit Breakers

    Automatic voltage regulation is essentially useful when you are powering sensitive appliances, including: personal computers and home theater systems. This helps to stop voltage fluxes that may significantly harm your appliances. Instant reset circuit breakers, on the other hand, help prevent damage to your connected appliances by shutting down power in the event of excess current passing through.

    1. Low Oil Shut Down System

    The best portable generator is one that is fully equipped with automatic low oil shut down system. The system is set to detect when the oil level hits the minimal mark, and shuts down the gen-set. This helps to prevent damage to the engine by protecting it from frying up.

    1. Fuel Tank Capacity and Run Time

    A good portable generator system should have a significantly large fuel tank capacity. For small types, you should consider a gen-set with at least 4 gallons fuel capacity; while for a considerably large portable generator you should consider a generator system with at least 10 gallons fuel tank capacity. The most convenient run time (hours/tank) is 10 hours per tank at half load on full tank. A gen-set with these features will run conveniently for a good number of hours without refill.

    1. Quiet Operation

    One of the most renowned virtues of portable generators is the ability to operate at relatively low noise level. Different types and models of portable generators are set to operate at specific noise level. However, it will be advisable for you to go for a gen-set that has at least 50 decibel noise level. You should know that a moderately noiseless portable generator is also promoted by the presence of super quiet muffler. The muffler ensures that the noise is reduced considerably.

    1. A Full Wheel and Handle Kit

    A good portable generator should have a full wheel as well as handle kit. These allow you to move the generator gently from one position to another with respect to your needs. The kit makes moving a portable generator a manageable task, particularly when dealing with a large portable generator.

    1. Electric Start and High Temperature Shutdown

    Most portable generators are equipped with a recoil start; however, it is convenient to go for a portable generator with an electric start system. Electric start is known to save wear and tear on your muscles, particularly during winter when temperatures are cooler. On the other hand, high temperature shutdown system helps protect a portable generator from overheating.

    Conclusion

    Portable generators will not only provide you with backup power for emergencies, household and commercial uses, but you get to save a great deal of money. The range of choices is great, running as low as 800 watts units to more than 10,000 watts units. The difference between 800 watts and zero is very significant, and 0.8kW is enough to keep much of your appliances running, including sensitive equipment. Nevertheless, there is one thing to watch out for as far as diesel portable generators are concerned. They tend to fade fast with increasing altitude, and they may not be useful at all at high altitudes. You need to check the specifications in detail if you reside in higher altitudes. As much as a specific model of portable generators is attractive to you; you are advised to also go through the customer reports ratings and reviews. They will help you understand what other customers have experienced about the portable generator you are about to purchase. In most occasions, customer reviews will help you make a more pronounced decision on a particular generator model, especially if it is the first time to make purchase.
