choosing the right genset: factors to consider

Choosing the right generator set involves more than just understanding the different types and sizes available. It requires a detailed understanding of your unique power requirements and the environment in which your generator will operate. Here, we’ll guide you through the basic factors you need to consider when choosing the perfect generator set.

portability

Generator sets are available in a variety of sizes and movement options. The most compact ones are usually portable and weigh around 20kg. Mobile genset are larger and have wheels, making them easier to maneuver. For high power needs, portable models are available. Their structural design can be moved with a forklift or placed inside a container for transportation. Finally, the largest and most powerful generator sets are stationary generator sets, intended for permanent installation.

start the system

Generator sets typically use one of two primary starting systems: electric or recoil starting.

Recoil starter generator sets use a pull-cord mechanism, and while this may require more physical effort, it does not rely on batteries and therefore is more reliable in some situations. We do not recommend this type if you must use your generator set regularly.

Most of the more powerful generator sets will come with an electric starter that is connected to the battery. The advantage of an electric start generator set is that it is easier to start, often with just the push of a button.

single phase or three phase

This refers to the type of electrical service the generator will provide. Single-phase genset are generally suitable for homes and small businesses with lower power needs. In contrast, three-phase genset can accommodate higher power loads and are suitable for industrial or commercial environments with high power consumption.

air or water cooling

Air-cooled genset are low-cost and simple in design, making them suitable for smaller, less commonly used equipment. Water-cooled genset, on the other hand, are more complex and costly, and are typically used in larger, more frequently used equipment because they are able to handle longer durations and higher power outputs.

Other important features to consider:

• Voltage Regulation System: A good voltage regulation system helps protect sensitive electronics from voltage spikes and fluctuations, ensuring smooth, “clean” power.
• Noise: Large genset can be very noisy, up to 100 decibels (dBA). If noise is a concern, consider purchasing a soundproof model for quieter operation.
• Transfer Switch: Automatic Transfer Switches (ATS) automatically start the generator when a power outage is detected and allow for smoother transfers during emergencies.
• Inverter technology: In addition to reducing noise levels, this technology also makes the generator more energy efficient and allows it to run at different speeds depending on the load, providing “cleaner” power to sensitive electronic equipment.
