1. Genergy electric generator

Welcome to Genergy Generators – the definative source for your backup electrical generator or engine needs. With engines, gen-sets, parts and service from Genergy, there’s a electric generator for you. Whether for main use, or use as a standby generator or emergency power generator, get the unit or engine you’re looking for with parts and service as well!!

Genergy manufactures gasoline electric generator, 1500 RPM diesel generator and a complete range of professional machinery. Genergy Zero Emission offers energy solutions more sustainable and respectful with the environment. Products that significantly reduce consumption and harmful emissions, and allow us to manage our electrical energy more intelligently.

Genergy generators, it should be noted, are rather less expensive than some other company’s generators. However, it comes with a longer warranty – theree years total warranty – than many of its competitors, it is designed to work well with transfer switches (which are needed to prevent dangerous feedback into the power lines during an outage), and can provide direct current (DC) electrical output for recharging batteries as well – all part of a compact, fairly light, and highly effective package.

2. What is an electric generator?

Let us start by describing electrical generator as a machine that transforms mechanical energy into electricity. This initial mechanical energy will be obtained through fourstroke combustion engines, one of the two most important parts that make up a generator. These engines are going to be fed by different types of fuels. The most common will be conventional 95 octane gasoline but we can also find options for diesel or even propane and butane gases.

An electric generator is a rotating machine that maintains an electrical potential difference between two points called poles, a device that converts mechanical energy into electrical energy. Its basic operating principle is Michael Faraday’s law of induction, and is achieved thanks to the connection between magnetism and electricity: a magnetic field acts on the electrical conductors arranged on the stator (static part or armature), this creates a magnetic flux that the rotor (rotating part or inductor) transforms into electricity by producing a relative movement between the conductors and the field. As a result, an electromotive force (EMF) is generated.

The other essential part of an electric generator alongside the engine is the alternator that is composed of an outer body called a stator, an armature, and an inner mobile, called a rotor or an inductor, that rotates when driven by the force of the combustion engine thanks to exitation through brushes. A magnetic field is generated between both bodies which as a result causes the production of an alternating current. Another especially important function of the alternators will be the regulation and stabilization of the voltage, avoiding oscillations that could endanger the connected devices. To achieve maximum stability and quality of current we will use voltage Regulators called AVR, SVR or an inverter. These devices will protect from possible variations even in the event of sudden or intermittent power demands.

The control panel is another important part of the generator where we will find the generator start stop buttons, the different electrical outlets, the overload or short circuit protections, grounding informative displays of the parameters of use or the start contacts in the case of automatic generators.

Other important parts to consider would be the quality of the frame, the transport kit, the
battery or the fuel tank.

3. Determining generator type

When selecting a generator, it is essential to know as accurately as possible what it will be used for during its life and more specifically the hours it will be running for daily. So first we need to determine if the customer will need it throughout the Working Day for sporadic uses during the day or for automatic uses without their presence.

The most common will be that the customer’s needs are either sporadic or interrupted, so we will opt for a portable generator with a 3 000 RPM (revolutions per minute) engine. This segment will be the main focus for most of the clients and potentially where we will find the need for other alternative units.

At Genergy we manufacture:
– standard generators with a gasoline engine from 1 up to 18 KW,
– inverter generators with a gasolina engine from 1 to 7.5KW,
– portable diesel generators from 3 to 7 KW and
– propane gas generators from 3 to 7 KW.

Depending on the quality of the different ranges, the maximum time that these generators will be able to work for continuously is around 5 to 7 hours and they can be used either domestically or professionally.

If the customer requires a unit that can work uninterrupted for long periods we should opt for a generator with 1500 RPM engine. These units work with diesel engines and are normally high powerered. At Genergy we manufacture generator sets from 10 kVA up to 350 kVA in both open and soundproof versions and single or three-phase units. For these cases, Genergy recommends that you seek advice from our technical or sales department as they are very high value equipment and there are logistical complications too, so we must find and offer the most efficient and precise solution on a case by case basis. These generators are intended for professional public outdoor emergency and rental uses.

Finally, we will find customers who require automatic generators that can be used conventionally, they can start or stop by themselves and will often be installed for protection against possible power outages and as an auxiliary source of load in photovoltaic installations. Our generators incorpórate all the automatisms in the control panel itself so it’s not necessary to install external panels that will only make installation more expensive and difficult. At Genergy, we manufacture this type of generator in both low power with gasoline engines between 6 and 8 kW as well as high power diesel generators from 10 up to 350 kVA.

4. Determine the power required

The required power of the generator to best suit our client’s needs will be calculated by adding the maximum power of all the appliances that we can keep connected at the same time, and increasing that number by 20%. We recommend a margin of 20% because it’s not recommended that generators work continuously above 85% of their potential load. Working with loads below 80% increases the life of your generator and results in significant fuel savings.

The appliances to be connected are divided into two groups: resistive or inductive. For resistive appliances (lighting, TV, Hi-Fi and electronics in general) the power consumption will be indicated on the name plate of the appliance in a uniform way from the moment it is switched on until it is switched off. Inductive appliances are motor-driven appliances that need extra power at startup. This excess power demand is for a very small time but it’s essential to take it into account or we won’t be able to start our equipment correctly.

As we said before, once we have calculated the maximum necessary power obtained from the sum of all the devices to be connected, both resistive and inductive, we will increase the power obtained by an extra 20% to avoid overworking the generator. As an example, if we have calculated a required nominal power of 4 000 W, we will go to a 5 000 to 5 500 W generator. This oversizing allows us to work around the nominal power of the generator which will allow us to save a significant amount of fuel as well as increase the longevity of the machine.

Remember to always check the power rating of a generator on its data sheet. It is quite a common mistake to confuse the name of the generator with the real power. Do not assume that the generator model Acme 4000 is a generator of 4 000 W of power. At Genergy our nominal and maximum power ratings are 100% real and you won’t find this a problem in any case.

5. Determine power quality

In Europe, we will use two types of voltajes: three-phase and singlephase:
– Three-phase 380 to 400 V units are usually reserved for high power and industrial equipment intended for professional or business customers to connect to large motors machines or pumps.
– Single phase units have the most common voltage 220 to 240 V and these suit the needs of a wide range of customers.

In Europe, we usually use these two types of voltages in alternating current generators.

Another fundamental factor in the quality of the electricity produced by a generator is frequency. In both voltajes, the energy varies from positive to negative in constant cycles called Herz which is the unit of measurement we use to determine the frequency. In most of Europe, we work at a frequency of 50 HZ and our generator must keep this parameter stable to guarantee and protect the connected appliances.

6. Determine voltage quality

The voltage and frequency of a generator can generate different oscillations ups and downs when subjected to intense or intermittent load variations. These oscillations can damage the connected equipment and to avoid them there are different voltage regulators or protectors on the market:
– The regulation by a capacitor is of low precision and can reach voltage variations of up to 20% or even higher with a high high risk of damaging equipment. However, it also withstands voltage surges which allows for extra power for starting inductive equipment. At Genergy we do not recommend or use this system in any of our generators, although there are manufacturers that continue to use them.
– The AVR system which is widely used in the market limits these oscillations to approximately 5% which allows the safe connection of most devices on the market. In the event of an overload it cuts the voltage to protect the equipment.
– The new SVR system implemented by Genergy in 2020 was a world first in the profesional ranges. It has all the advantages of the AVR but can withstand and manage overloads that allow us to start inductive equipment of much higher power than equipment with AVR. With this device, at Genergy we can combine the benefits offered by the AVR and the capacitor at the same time.
– The highest quality voltage option is offered by inverter regulators that reduce voltage oscillation to only 2% to 3%. They are especially suitable for use in extremely sensitive equipment (electronics, computers, lighting, Wifi, etc.) so it should not be recommended for use with particularly aggressive devices such as welding machines nor in construction work sites as dust, dirt and stones can damage them.

7. Genergy equipment

Once we have selected the type of generator, the power we need and the quality of current for our needs, various options will be open to us.

We guarantee the highest quality:
– Alternators wound with 100% copper which guarantees greater longevity and better current quality during the generator’s lifetime

9. Start up

Now that we have our geny generator, we’re going to start it up. First, we will proceed to remove the generator from its box and place it on a firm and stable base, we will also check and order all the accessories for the assembly such as wheels, handles tools and the user manual. Ee then proceed to the assembly of the wheels and handles in the models that require them.

Next, we put oil in the engine. How much oil you need is indicated in the manual, this is dependent on the size of the engine, normally it will be a standard SAE 10W30 oil for gasolina engines. The oil level should cover half of the thread of the inlet port for optimum performance. Both an excess or deficiency in the oil level will not allow it to start or even shut it down preventively.

Once the oil is in, we will put the fuel 95 octane gasoline in and pour it through the inlet filter to avoid rubbish from entering the tank. Remember to wait 15 minutes after turning off the generator before refueling. It should never be done with the generator running. Once the equipment is refueled, we will open the gasoline stopcock to the engine.

Only for models with electric startup, we will connect the battery terminals. In all Genergy generators, the positive and negative poles are indicated or differentiated by colors to avoid confusing them. Once the battery is connected, we will turn on the generator from the main switch from off to on and the generator will now be ready to start.

Inmediately before starting, we will close the air inlet from the starter lever, this will produce a richer fuel mixture and will facilitate the initial start. Once closed, we will start it with a manual puller or with the switch or ignition key if it’s electric. After a few seconds we will take the starter lever to the initial position, letting it breathe and we will make sure that after a few seconds the engine is stabilized and the generator will be ready to work.

When we finished we turn off the generator, simply by turning the main switch to the off position and we must remember that both at the start up and shut down phases there should be no appliances connected to the generator.

If you have any doubts or problems during the starting of your generator, please contact our customer service team and we’ll be happy to help you.
