Consider motor starting surge; plan ventilation for high ambient temps
Poultry houses Ventilation fans, lighting, feeding, water systems Standby genset + ATS + silent canopy (if near housing) Fast transfer protects animal welfare; noise may matter
Dairy farms Milking systems, cooling, refrigeration, pumps Standby/prime genset + ATS + stable voltage regulation Prioritize reliable startup and steady power for sensitive equipment
Greenhouses Ventilation, heating, circulation fans, controls Standby genset + ATS + low-noise enclosure (as needed) Long outages can damage crops—plan runtime and fuel logistics
Grain drying & storage Dryers, conveyors, aeration fans Prime/standby genset + robust cooling + dust-ready maintenance plan Dusty environments require filter discipline and radiator cleaning
Remote farm standby Whole-site backup, intermittent outages Standby genset + ATS + remote monitoring Remote alerts reduce downtime and service trips

Notes: Final sizing depends on motor starting method (DOL/soft starter/VFD), duty cycle (standby vs prime), ambient temperature, altitude, dust level, enclosure type, and fuel supply logistics.

Recommended Generator Configurations for Agriculture


Energy needs in the agricultural industry

The energy demands in the agricultural sector vary widely, leading to a diverse range of power generators and their capabilities. We focus on addressing these requirements through the following tasks:

Implementation of irrigation systems

Electric pumps for irrigating large areas of land that lack direct access to the power grid.

Tool use

Use of tools requiring an electrical power source.

Electric power from the tractor

Harnessing electricity from the tractor as the sole available energy source.

Emergency use of generators

Using electricity generators as an emergency backup during mains power outages, particularly on farms and livestock operations.

Agricultural Generator FAQ

1What size generator do I need for an irrigation pump?
The right generator size depends on the pump motor rating and the motor starting method (DOL vs soft starter vs VFD). As a rule, you should size for running kW plus starting surge—a pump that runs comfortably can still trip a small generator during start. Share your motor kW/HP, starting method, voltage/phase, and whether pumps start one-by-one or together. If you don’t know the surge, we can estimate it from motor data and recommend a kVA range.
2Do farms need an ATS for standby power?
If you need power to restore automatically during outages (especially for livestock ventilation, milking, refrigeration, or greenhouse controls), an ATS is strongly recommended. An ATS senses utility failure, starts the genset, and transfers loads automatically—reducing downtime and labor. For critical farm loads, ATS also helps ensure a consistent, repeatable startup sequence. If you only use the generator occasionally and can start/transfer manually, a manual changeover can work, but response time is slower.
3Can a diesel genset run irrigation all day?
Yes—diesel gensets can run irrigation for long hours, but you should choose the right duty rating (prime/continuous) and plan fuel and maintenance intervals. For daily irrigation runtimes, a prime-capable configuration is usually safer than a standby-only unit. Make sure cooling and ventilation are designed for high ambient temperatures, and avoid running at extremely low load for long periods. Plan refueling logistics (tank size, delivery schedule) and basic checks (oil level, coolant, filters) during the season.
4How do I handle motor starting surge on pumps and fans?
The best way is to reduce starting surge using a VFD or soft starter, or by sequencing starts—this often reduces the required generator kVA significantly. Direct-on-line (DOL) starts can create a high inrush current that causes voltage dip and trips. Practical options: - Start motors one at a time (staggered sequence) - Use soft starters (reduced inrush, simple control) - Use VFDs (best control and often the lowest starting impact) Also ensure the generator has adequate alternator capacity and voltage regulation for motor loads.
5How to choose a silent generator set near livestock housing?
Choose a genset with a silent canopy (or super-silent enclosure) and design the installation for noise control—not just the machine rating. Ask for a noise figure with a stated test distance (commonly 7 m / 23 ft) and load condition, then plan placement away from reflective walls and animal housing. Use proper exhaust mufflers, flexible connections, and vibration isolators. If noise is very strict, consider an acoustic enclosure plus site measures (barriers, distance, orientation).
6Prime vs standby: which one is better for my farm runtime?
If your generator runs only during outages, standby is usually enough; if it runs many hours per day or supports irrigation season operations, choose prime/continuous. Standby systems prioritize quick emergency response and are often paired with ATS. Prime power setups are designed for longer daily runtime, steadier thermal performance, and predictable service planning. If your farm uses the genset regularly (not just emergencies), prime-rated equipment generally delivers better lifecycle reliability.
7What maintenance is required in dusty farm environments?
Dusty farm sites require stricter air filter and radiator cleaning discipline than clean industrial locations. Expect more frequent checks and replacements of air filters, and regular cleaning of radiator/fan areas to prevent overheating. Keep an eye on fuel quality (water/contamination), and follow an oil/filter service schedule based on runtime hours. A simple seasonal routine—pre-season inspection, mid-season checks, post-season service—helps prevent downtime during peak operations.
8How do I plan fuel storage and runtime during peak season?
Plan runtime from your expected load and daily hours, then size fuel storage to cover your refueling constraints and safety requirements. For peak irrigation periods, choose a tank strategy that matches your site logistics: built-in base tank + optional external day tank, or a larger bulk tank where permitted. Include a buffer for load variability, and consider fuel quality management (filtration, water separation, rotation). If you share your runtime hours/day, estimated load, and delivery access, we can recommend a practical tank capacity plan.

FAQ

Frequently asked questions

What size generator do I need for my farm?Add up the running kW of everything that must run at once (ventilation, pumps, cooling, lighting), then add the starting surge of the largest motor. Most working farms land between 20 and 200 kW; share your load list and we will size the kVA for you.
Should a farm generator be standby or prime power?If the grid is your main supply and the generator only covers outages, standby rating is fine. If the generator runs daily or is the main power source (remote farms, irrigation seasons), choose a prime-rated set with a larger service interval.
Are diesel generators better than petrol for farms?For farm duty, yes in most cases: diesel sets run longer, burn less fuel per kWh, handle motor loads better, and last far longer at continuous load. Petrol suits only small, occasional loads.
