Petrol (gasoline) generators are the most widely available entry-level units in India. They are lightweight, easy to start, and usually come with a pull-cord or electric start. Their power output ranges from 1 kVA to 7 kVA, making them suitable for small apartments, single-room offices, or as an emergency starter unit.
Diesel generators dominate the Indian market for medium to large residential applications. They offer higher torque, better fuel efficiency and can run continuously for long periods. Capacities typically range from 5 kVA to 25 kVA, and many models are equipped with automatic voltage regulation (AVR) and low-oil shutdown features.
Inverter generators combine a traditional engine with electronic circuitry that produces clean, stable AC power. They are ideal for sensitive electronics like laptops, televisions, and home automation systems. Power output usually ranges from 2 kVA to 5 kVA, and many units feature fuel-saving modes that adjust engine speed based on load.
Solar hybrid generators integrate a conventional engine (usually diesel or petrol) with a solar panel array and battery storage. They can run on solar energy alone for low-load periods, reducing fuel consumption dramatically. Capacities vary widely, from 2 kVA to 10 kVA, depending on the solar panel size and battery bank.
Choosing the right generator capacity is critical to avoid under- or over-sizing, both of which can cause inefficiencies or damage to equipment. The table below lists typical household appliances and the approximate kVA they consume. Use this as a reference to calculate the total load you expect to run simultaneously during a power outage.
