Questions and answers

What type of generator do I need?
We offer generator sets as main power supply systems, backup power supply systems, and also rent them out. We supply diesel and petrol generators from 2kVA, ideal for domestic use and small retail outlets, to 2500kVA and more, which can power entire villages and even feed into the grid. Our generators can be started either manually or automatically and can be supplied as open systems, protective hoods or containers. It is also possible to install the generator on a trailer if there is a need to transport it.

The type of generator you need will depend on the facility that needs to be powered, where it will be installed, and whether it will be needed all the time or only during power outages. In order to determine which type of generator is most suitable for you, contact our specialists who will be able to analyze your requirements and determine their cost.
How do I determine what generator power should be purchased for my facility?
There is no clear answer to this question. The power of the generator will be determined by many factors. In order to make sure that the power of the generator set is determined correctly, you should contact our specialists. They will come and help you determine the power in kVA or kW for all equipment and devices in your facility that will draw power from the generator. This will enable them to provide you with detailed information on what type and power generator will best suit your needs.
What is the standard equipment of FG Wilson generator sets?
All generators consist of a set of different parts. The main components included in the standard composition of FG Wilson machines are as follows:

• Engine

• Control panel

• Body and fuel tank

• Generator

• Switches

• Fuses

• Cooling system

It is possible to order auxiliary functions that can be ordered when completing the FG Wilson generator set for an easier selection of the product that meets the individual requirements of the consumer.
What do I need to know about generator set installation?
When making a decision to install a generator unit, the following must be taken into account:

• Location - You will need to decide where you want to install the generator set - ideally it should be installed in areas with adequate lighting and access to the generator for operation and maintenance. Generators can be installed indoors or outdoors - NVP "MADEK" offers noise protection hoods for generators installed outdoors.

• Installation - generator units should be installed on a flat horizontal surface, and if necessary, use anti-vibration pads. In most cases, the mounting surfaces meet the requirements, but a structural engineer should be consulted when installing the generator on the ground or roof.

• Ventilation and cooling - it is important to ensure that the air current is sufficient to cool the generator and eliminate the smoke and heat emissions produced by the combustion of fuel in the engine.

• Fuel system - you should think about how you will fuel your generator. There are several options, from manual pumps to automatic filling systems. Small units usually have a manual electric or mechanical pump capable of filling the unit's main tank from a reservoir.
Can I connect a generator set to my home power system?
Generators can be connected to your home electrical system via a transfer switch, which of course must be made by highly qualified electricians. Trying to connect such a system yourself is dangerous for you.
How does the generator work with the mains?
Feed electricity is supplied to the premises by electrical cables. When the power supply from this source is interrupted due to a power outage, a signal is sent from the transfer switch to the generator unit, which then starts and returns the generated electricity back into the room. When utility power is restored, the transfer switch disconnects power from the generator and returns to utility power.
What is a transfer key?
At the moment, two types of switches are supplied - manual and automatic. The transfer switch is a panel that is connected to the electrical power system of the room, which allows you to use the generator set. It prevents the generator from delivering power to the utility grid, which can seriously injure workers trying to restore utility power.
How long will the generator work on one tank of fuel?
The amount of time a generator will run on a single tank of fuel depends on the size of the tank, the amount of time the generator is running, and the generator's power consumption load. All FG Wilson generators are designed to operate for a minimum of eight hours at maximum possible load.
How long can a backup generator run continuously?
There is no specific answer to this question. Generators are designed for long-term operation in difficult conditions. However, it is important that the unit is inspected periodically after each use, that the fuel and oil levels and any signs of abnormal operation are checked before restarting. Our generators can run continuously when the load is reduced.
Will the generator be loud?
All generators produce some level of exhaust, engine, and airflow noise. The generators are designed to provide maximum noise control and are noise tested during production to comply with applicable legislation. Our generators can be supplied with sound-proof or super-sound-proof hoods that absorb excess noise.
Is it possible to build fences around generator sets?
We supply both outdoor generators and hooded generators - if your generator will be installed outside, we would recommend buying a hooded generator. This means that you will not have to build a fence around it. Generator sets require air flow to cool generator set components such as the engine. With long-term operation of the generator, long-term air circulation will occur, which may be undesirable for home fencing. FG Wilson generator sets in hoods have louvered air cooling systems that allow air to blow through various generator components. Poorly made enclosures can cause excessive redistribution of air, which leads to dust or moisture from rain entering the generator, causing premature failure of the generator.
Can the generator set be used in adverse weather conditions?
Generator sets supplied by NVP "MADEK" are designed to work in adverse environments and extreme weather conditions. To extend the service life of the generator and avoid such phenomena as shorting and corrosion, the units should be protected, if possible, from the effects of natural elements.
Where and how should I service the generator set?
The frequency and type of maintenance required to keep the generator in working order will depend on several factors, including the use of the generator, the environment in which the generator is operating, and the degree of load it is operating under. You, as the owner, are responsible for the timeliness and completeness of the service. You will need to carry out frequent visual inspections every two to three months to make sure that the unit is working properly - any breakdowns and malfunctions that you notice must be reported to our specialists. A full service, including things like changing filters and oil, should be done every 12 months. Most cases of generator failures during start-up are the result of the unit not being periodically inspected. We recommend that you inspect the generator every week.
What is the warranty on generator sets?
The warranty on generators varies depending on the manufacturer. All FG Wilson back-up generators come with a two-year warranty (limited to 500 hours of use per year from the date of launch).
What can happen when the generator set is overloaded?
Generating sets should not be overloaded, but they are designed to be overloaded for a short time when the unit is started. If the unit operates for a long period of time in an overload state (the degree of load is higher than the maximum permissible for the unit), various phenomena may occur.

Among them are:

• Overheating of the cooling system

• Overheating of the windings of the alternating current generator

• The viscosity (thickness) of the oil drops, leading to low oil pressure

• Reducing the service life of the generator set
What will happen if the generator set is underloaded?
All generators are designed to work with different loads, varying from the maximum permissible to the minimum. Problems occur when light loads (minimum loads) continue for long periods of time, causing the engine to not warm up to normal temperature. The oil in the cylinder to be burned is heated, and a vitreous film forms on the cylinder liner. If light loads are used over a long period of time, blue smoke will appear and the engine will need service to remove the vitreous film or replace the gasket.
