OJU Systems·19 May 2026·5 min read
The biggest mistake is guessing and that is why talking to a professional like OJU Systems Technology is essential . An inverter that's too small for your home or office gadgets, trips constantly; one that's too big wastes money. So, how do you know what you need?
List your essential loads
Write down everything you need to keep running during a power outage — lights, fans, ACs, fridge, TV, laptop — and if possible, add up their wattage.
Account for start-up surge
Appliances like fridges, ACs and pumping machines draw extra power briefly when they start. Whatever inverter you will be getting must be able to handle this surge.
Get a load analysis
The reliable way to size a system is a proper load analysis. At OJUSYSTECH, we do this as part of every power solution we quote.
