What size generator do I need for my home or business?
The size of the generator you need depends on the total wattage of the appliances or systems you want to power during an outage. For basic home use (fridge, lights, small appliances), a portable 3–5kW unit may be sufficient. For larger homes or businesses with air conditioning, pumps, or heavy machinery, a generator between 7kW and 20kW may be more appropriate. A licensed electrician can calculate your power needs and recommend a generator that won’t overload or underperform.
What is a change over switch and why is it important?
A change over switch allows you to safely switch your power source from the grid to a generator. This prevents backfeeding into the mains (which can be dangerous for utility workers) and ensures your generator powers only what it’s meant to. Manual change over switches require you to flip the switch when the power goes out, while automatic transfer switches detect outages and start the generator automatically. Both are critical for a safe, compliant backup power system.
How often should a backup generator be serviced?
Most manufacturers recommend servicing your generator at least once a year or after every 100–200 hours of use—whichever comes first. Maintenance typically includes checking the oil and filters, inspecting connections, testing the battery, and running a load test. Regular servicing ensures your generator will work when you need it most and helps extend the life of the unit. If you rely on it heavily or live in an area prone to outages, more frequent checks may be worthwhile.
