Frequently Asked Questions About Generators
A generator is an electrical machine that converts a form of energy (mechanical energy) into electric power. It provides an electric source during a power outage to avoid disrupting daily activities or business operations.
There are several types of generators in the Philippines, namely:
- Whole House – Also called a standby generator, this generator connects to an in-house electrical system and a fuel source, such as natural gas or propane, to keep all appliances running during a power outage.
- Portable Generator – A portable generator is a gasoline- or diesel-powered device that is small in size but has a variety of applications and is more cost-effective than a whole-house generator.
- Inverter Generator – This generator adjusts its engine speed automatically, reduces noise and emission levels, and produces clean energy.
- Gasoline Generator – This is the most prevalent type of generator, which uses a gasoline engine to power light appliances and tools.
- Diesel Generator – A diesel generator is more fuel-efficient, robust, and durable than a gasoline generator due to its low burning temperature.
The price of a generator varies depending on its size, model, wattage output, engine speed, manufacturer and installation process.
Most people invest in generator sets for the following reasons:
- No access to mains electricity
- Insufficient mains supply
- Protection against potential power losses
Generators are covered by a two-year warranty, limited to 500 hours per year following installation and any failure that results from defects in the unit’s design.


Consider the following factors before installing a generator set in the Philippines:
- Location – Ensure that the generator set is placed in an area with proper lighting and access for service and repairs.
- Mounting – Generator sets should be placed on a level base with anti-vibration mounts if necessary.
- Ventilation and Cooling – The generator needs sufficient ventilation for adequate cooling and to reduce heat and fumes from combustion.
- Fuel System – It comes in many options, including manual pumps and fully automatic systems.
A transfer switch is an electronic panel connected to the electrical distribution system that enables generators to work. It prevents the generator from back-feeding into the power supply, which results in injuries to line workers.
Most generators emit intense buzzing or mechanical noise because of their exhaust, engine, and airflow.
A gas-powered generator typically runs for several hours or even 24 hours, while a portable generator has a large fuel capacity that can last for a number of days.
A generator will operate for as long as fuel is available, although it can supply power to a residence for an average of 3,000 hours.
Underloaded generators may fail to reach their peak operating temperature, causing the burnt oil to be heated and form a lacquer on the cylinder liners.
Generator sets are well-designed to withstand harsh environments and adverse weather conditions. Shielding of components is required to prevent shorts and corrosion.
When and How Do I Service and Maintain My Generator Set?
A generator set’s maintenance requirements depend on some factors, including its usage, the environment, and the load it carries. Check the generator frequently or consult with a provider for repairs.
