Generator FAQ


Should I buy a standby or portable generator? 0

Why should I buy an Aurora Generator home standby generator instead of a portable generator?

While portable generators are effective in terms of backup power, an Aurora Generator home standby generator produces more power, offers hassle-free, automatic operation even when you aren't at home and exercises to ensure extended life.

With a home standby generator, there is no need to run extension cords, the unit will operate rain or shine, and it will automatically turn on even when you are not home.

Standby/Emergency, Prime, or Continuous Power Supply for my home or business?


There are numerous reasons for individuals or businesses to own their own backup/standby, prime or continuous power supply generator set(s). Generators provide an added level of insurance to your personal daily routine or business operations ensuring uninterrupted power supply. The inconvenience of a power outage is rarely noticed until you are the victim of an untimely power loss or disruption.

Backup Power for individual residences can avoid the inconvenience of power outages by purchasing a small backup generator. Electricity is essential to maintain lighting, HVAC, refrigeration, electronic entertainment equipment, household appliances, water in some cases and security systems.

The inconvenience of losing power may not be realized in your pocket book but rather in the safety and well-being of your family. Houses and small residences only require a small amount of backup power, typically in the neighborhood of 8-10kW. Larger residences or businesses may require more power, which will increase the cost slightly, but still is highly affordable considering the benefits of owning your own power supply.

As a business owner, an emergency standby generator provides an added level of insurance to keep your operation running smoothly without interruption. Luckily, the decision to purchase a generator is easily made by performing some basic financial calculations.

First, you must determine how much money your business generates on a daily basis. Only consider the revenue that is strictly dependent on the power supply (i.e. phones, computers, payment systems, electricity, process equipment, machinery used for the business, etc.).Next, factor in any capital equipment or assets that depend on a power supply in order to maintain its value (i.e. perishable goods, etc.). You must also consider costs that are associated with a startup or shutdown of a process or manufacturing line.

Costly startups and shutdowns due to power outages can prove to be very costly. Paying employees to wait around until the power is restored not knowing how long it may be can add up to hundreds if not thousands of dollars depending on the number of employees you have. Finally, add up all of these costs and multiply it by the number of power outages you have each year. This will give you your annual operating losses due to power disruptions. Dividing the cost of the generator by these potential losses will determine how many months it would take for the generator to essentially pay for itself.

Costs alone should not be the driving factor in purchasing a generator. Another advantage to having a localized backup power supply is to provide a consistent power supply to your business. These expensive company assets require consistent power quality in order to function properly.

Generators also allow for end users, not the power companies, to control and provide a consistent power supply to their equipment. End users also benefit from the ability to hedge against highly volatile market conditions. When operating in a time-of-use based pricing situation this could prove to be a huge competitive advantage. During times of high power pricing, end users can switch the power source to their standby diesel generator for more economic power.

What is the difference between air-cooled versus liquid-cooled generator? 0

What is the difference between air-cooled versus liquid-cooled generator?


Air-cooled systems work by forcing air to the engine's metal fins around the engine cylinder only. Liquid-cooling systems, on the other hand, have a radiator and a water pump. The pump cycles the thermostatically controlled liquid coolant to the engine block through hoses, and the heat from the engine is transferred to the coolant. The heated liquid then goes to the radiator where the air cools it. Diesel generator engines commonly use liquid-cooling, but you will find all portable and most liquid propane, natural gas generators are air-cooled engines models only.

Air-cooled engines are generally cheaper to produce than liquid-cooled engines. This is because their components are less expensive to produce, need fewer parts. Air-cooled engines can easily overheat and have a much shorter engine life. Since air-cooled engines have the potential to overheat, using them full time is not recommended, nor warranted. Air-cooled engines that fail generally require either a major overhaul. Their maintenance and repair tasks tend to be more frequent and more time-consuming.

Since air-cooled engines in either portable generators or home standby LPG or LNG work at much faster speeds, they also wear out much faster. Oil break-down also happens faster and damage can occur with little warning.

Aurora Generators recommends you do NOT run air-cooled engines full-time. Shut down your air-cooled engine every few hours so it can cool. This is a good time to check your oil, add fuel and perform a general maintenance and/or inspections. All Aurora Generators are liquid cooled ranging from as small as 8kW - 30kW.

What types of generators are there? 0

There are 3 primary types of generators: Air Cooled Portables - These are usually a gasoline air cooled engine operating upwards of 3600 rpm. Used for small portable power needs, whether it be light commercial or for small home periodic portable standby. These generators are manually operated, recommended for short monitored run times only and cannot be used for automatic home standby.

Standby Generators - These are fixed installations including electrical connections and fuel supply (LPG and LNG). Engine plants can be either Liquid Propane (LPG), Natural Gas (LNG) or Diesel. For home or small business standby, all other generators except diesel are air cooled operating upwards of 3600 rpm. Aurora Generators are diesel liquid cooled engine plants operating at 1800 rpm. When paired with an automatic transfer switch, standby generator systems can detect any interruption in power from the utility company and automatically provides alternative power from the standby generator system. When utility power returns, your standby generator system will revert power back to the utility and the generator will shut down automatically.

Commercial Generators - These can be either portable such as trailer mounted, or fixed installation which includes prime power. Both engine and alternator are designed and equipped to be more rugged and durable. Engine equipped is more commonly diesel due to its far superiority in both longevity, fuel economy and lesser overall operating expense. On board, safer diesel fuel supply eliminates costly additional external fuel connections or supply such as the case for LPG or LNG require.

Alternators are heavy duty built providing both better longevity, reliability and cleaner power. Prime power generators are a continuous source of power when there is no access to public electric utilities. Applications are for off-grid cabins/cottage, military or remote commercial businesses.

What does a generator do? 0

What does a generator do?

Our society has become increasingly dependent on electrical power for everyday needs such as lighting, climate control, cooking, water, refrigeration, computers and home security which all need electricity to work properly. There are times when you could be without power for a few minutes, hours, days even weeks. It could be an equipment failure on the part of the utility company or severe weather that disrupts the power grid.

The purpose of a generator is to take over when power is lost or not available and provide you with the electricity you and your family need and depend on.

What is a generator? 0

A generator is a device for locally producing electrical energy on demand. This is mainly used as a backup to the main electricity supply and can automatically start and provide electricity for as long as the outage lasts. Other applications include commercial, construction, off grid backup or even prime power. A generator consists of a mechanical engine and electrical alternator.

The engine is the mechanical drive source which powers the electrical alternator output source. Engines can either be gasoline, liquid propane, natural gas, or diesel. This alternator contains a rotating mass of copper (rotor) and a stationary magnetic field (stator). When the rotor spins within the magnetic field it produces electricity at the alternator terminals. This is, of course, a simplistic statement and many other processes and controls are required to produce stable electricity at the correct voltage and frequency.

What is Battle Run?

Battle Run on a DynaGen controller means the generator is running with the controller ignoring all warnings and errors. This is used when you want to run the generator at all costs. The controller will not shut down for any warning or failure.  

If it is in Battle Mode, either someone turned it on or you may have changed a setting by mistake.
