Generators BullMach

BullMach generators provide electricity where mains power is unavailable or when a backup power source is required. They can be used in homes, construction sites, workshops, farms, mobile facilities and outdoor activities. The range includes compact models for electronic equipment and generators with higher power outputs for tools, pumps, machinery and household appliances.

BullMach develops equipment for agriculture, gardening, construction and transport. The brand has expanded its range to include generators, space heaters, garden shredders, mini dumpers, power stations and other equipment. Its operations are based in Italy, with offices in Castel Ritaldi, warehouses in Bastia and Castel Ritaldi and a central workshop in Spoleto dedicated to after-sales support and repairs.

The page dedicated to BullMach generators also includes the following types, divided according to power-generation technology, fuel type and starting system:

• BullMach inverter generators: they produce electronically regulated power and are suitable for sensitive devices. Their compact size makes them easier to transport for camping, leisure activities and small jobs away from the mains;
• BullMach petrol generators: these include models with different power outputs, sockets and single-phase or three-phase configurations. They are suitable for temporary power supply at home, in workshops, on construction sites and on farms;
• BullMach automatic-start generators: they use an ATS system to detect a mains failure and start the engine. They are intended for backup applications where automatic power restoration reduces downtime;

At AgriEuro, BullMach generators can be selected according to their technical features, helping users identify the model best suited to the appliances being powered, the working environment and the expected operating frequency.

• Maximum and continuous power: the first indicates the peak output available for limited periods; the second is the reference value for regular operation. The calculation must include the combined loads and the starting power required by motors, pumps, compressors and refrigerators;
• Inverter technology or AVR regulation: an inverter electronically controls voltage and frequency and is suitable for sensitive equipment. An AVR stabilises the voltage of conventional generators and supports the power supply of many types of work equipment;
• Single-phase or three-phase power: single-phase models supply common 230 V appliances; three-phase models are intended for machines designed for 400 V. The selected configuration must match the voltage required by the connected equipment;
• Starting system: recoil starting provides a simple configuration, whereas electric starting makes ignition easier through a key. An ATS system automatically starts the generator when mains power fails;
• Running time and fuel-tank capacity: these values help determine refuelling intervals. Actual running time varies according to the connected load, operating conditions and generator model;
• Transport and socket equipment: weight, handles, wheels and the number and format of the sockets affect mobility and connection options. Each appliance must comply with the voltage, frequency and power limits specified by the manufacturer;

Compact models are suited to hobby applications, including camping, lighting and small tools. Semi-professional machines are intended for periodic work in workshops, construction sites or farms. More demanding applications require careful assessment of continuous power, operating duration and compatibility with the actual loads.

The BullMach range addresses different requirements through three main configurations. The selected technology affects power quality, available output and operation during a power cut. Comparing the available types makes it possible to match the machine to the intended appliances without arbitrary oversizing.

BullMach inverter generators convert the energy produced by the engine into electronically regulated power with stable voltage and frequency. This architecture makes them suitable for computers, televisions, electronic instruments, battery chargers and other equipment sensitive to voltage fluctuations. The range includes compact single-phase models designed for frequent transport and moderate power requirements. They can be used for camping, mobile activities, small maintenance jobs or temporary power supply away from a socket. Selection should begin with the continuous power required by the appliances and their possible starting demand. The number of sockets, stated running time, noise level and machine weight should also be checked. A power reserve consistent with the expected loads helps prevent overloads and protective shutdowns during operation.

The following factors should be compared before purchasing:

• Power stability: suitable for electronic devices and equipment fitted with control boards;
• Continuous power: it must cover the expected simultaneous load and starting demand;
• Portability: low weight and handles make transportation between different locations easier;
• Running time: this should be compared according to the applied load and expected operating duration;

BullMach petrol generators cover a range of power outputs suitable for both domestic requirements and activities in workshops, construction sites and agriculture. The petrol engine drives the alternator and supplies electricity through the sockets installed on the control panel. Depending on the model, the range may include 230 V single-phase or 400 V three-phase power, AVR regulation, recoil or electric starting and a wheeled frame. Wheels and handles assist with moving heavier machines around the work site. Single-phase models are suitable for power tools and common appliances; three-phase models should be selected for compatible machinery and with correct load distribution. Sizing must be based on continuous power rather than maximum output alone. Fuel-tank capacity, consumption, running time, sockets and safety devices complete the comparison between the available configurations.

The models can be assessed according to the following features:

• Single-phase configuration: suitable for 230 V appliances commonly used in domestic and trade environments;
• Three-phase configuration: intended for 400 V equipment and to be sized according to load distribution;
• AVR regulation: helps maintain a more stable output voltage when the connected load changes;
• Wheeled frame: makes heavier generators easier to move across even surfaces;

BullMach automatic-start generators are designed to operate when mains power fails. The ATS panel detects the loss of voltage, starts the generator and transfers the load according to the system configuration; once mains power returns, it performs the reverse transfer and stops the machine. These models are suitable as a backup source for homes, workshops, small businesses and appliances that must not remain without power for extended periods. Selection requires an accurate estimate of priority loads, including the starting demand of motors, pumps and refrigeration systems. Compatibility between the generator, ATS and electrical system must be checked. Connection to a building's distribution board must be designed and completed by qualified personnel using suitable transfer and protection devices. The starting battery, fuel and scheduled maintenance must also be checked to preserve operational readiness.

The following points should be considered when selecting an automatic configuration:

• ATS panel: detects the loss of mains power and coordinates the transfer of the power supply to the generator;
• Electric starting: uses a battery whose charge level must be checked periodically;
• Priority loads: their combined power and starting demand determine the correct generator size;
• Professional installation: prevents power from feeding back into the grid and provides switching suited to the electrical system;

Add together the power of all appliances that will operate simultaneously and account for their starting demand. Lights and resistance loads have relatively linear power consumption; refrigerators, pumps, compressors and power tools may briefly require more power than their rated value. The generator's continuous output must cover the normal load while providing a suitable reserve for starting peaks. The rating plates and manuals of the equipment should be checked before choosing a model.

Continuous power indicates the output available during normal operation; maximum power is only available for limited periods. The continuous rating should be used when sizing a generator. Maximum power can support brief additional demand but must not become the machine's normal load. Constant operation close to or beyond the stated limits may activate the safety devices, increase wear and make the power supply unstable.

An inverter model is suitable when sensitive electronic equipment needs to be powered or when compact dimensions are required. The system electronically regulates voltage and frequency, providing power suitable for computers, televisions, battery chargers and devices fitted with electronic boards. It is also useful for camping, mobile activities and small jobs. Available power remains the primary criterion: all simultaneous loads and their starting demand must remain within the values specified for the model.

Inverter technology electronically reconstructs the output waveform with precise voltage and frequency control. An AVR is an automatic regulator that stabilises the voltage produced by a conventional alternator. The two solutions are not equivalent: inverter models are often preferred for sensitive electronic devices, whereas AVR systems are common on generators intended for tools and work equipment. The choice depends on the type of load, required output and instructions supplied by the manufacturer of the connected equipment.

The generator must have the same electrical configuration as the appliances it will power. A 230 V single-phase model is suitable for most household appliances and common power tools. A 400 V three-phase model is required for machinery designed for that voltage. Loads must also be correctly distributed between the phases of a three-phase generator: the stated total power may not be fully available through a single-phase socket.

The ATS system detects a mains failure, starts the generator and transfers the power supply to the connected loads. When stable mains power returns, the panel performs the reverse transfer and stops the engine according to the specified sequence. The ATS must be compatible with the generator and electrical system. System design, connection to the distribution board and protective devices must be entrusted to qualified personnel to prevent dangerous power feedback into the public grid.

No. A generator must never be connected directly to a household socket. Connection to the electrical system requires a transfer device that separates the public grid from the backup source, together with earthing and protective devices suited to the installation. A qualified technician must check the output, circuit diagram, neutral conductor, residual-current devices and ATS compatibility. An improvised connection can cause power feedback, damage equipment and expose people and grid technicians to serious hazards.

Maintenance includes the checks specified in the manual for the engine oil, air filter, spark plug, fuel and fasteners. Before each start, the oil level, absence of leaks and condition of the sockets should be checked. Petrol must be fresh and stored correctly; the manufacturer's procedures should be followed before extended periods of inactivity. On models with electric starting or ATS, the battery should also be checked and periodic starting tests completed.

A petrol generator must operate outdoors, on a stable surface and in a well-ventilated position away from doors, windows and air intakes. Exhaust gases contain carbon monoxide and must not accumulate inside rooms, garages or partially enclosed spaces. The machine should be protected from rain and standing water without obstructing ventilation. Distances, earthing, refuelling and protective measures must comply with the specific manual; fuel should only be added with the engine switched off and cool.

Operating duration depends on the model, fuel-tank capacity, connected load and the limits specified in the manual. The stated running time normally refers to specific load conditions and may decrease as power demand increases. The running time provided by a full tank should not be confused with the permitted continuous operating period. The manufacturer's inspection and shutdown intervals must be followed, and the tank must never be refuelled while the engine is hot or running.
