You can add up the power ratings of all the electronic appliances, then choose the suitable inverter. Some appliances, like table saws, refrigerators, and ovens, have a surge requirement. Some inverters are uniquely designed to supply such surges, but since all appliances have their own requirements, you should get a bigger inverter than you otherwise plan.
The battery of the inverter must also be able to supply the required surge power, and the cables should be able to supply the increased current without dropping the voltage.
Yes, you can power your computer with the inverter. The sine wave inverters can easily and safely give power back-up to a computer without any problem or risk. In fact, the output voltage from an inverter is better than the electricity grid or the shore power.
The inverters, having a battery charger and a battery set, are often used as a back-up system where the grid connection is unreliable. Laptops can also be powered by an inverter.
The gadgets that work well with a modified sine wave inverter are computers, electric blankets, motor-driven appliances, toasters, coffee makers, stereo players, printers, refrigerators, TVs, ovens, etc. However, the appliances which are known to have problem with the modified sine wave inverter are digital clocks, battery chargers, light dimmers and battery-operated appliances.
There are many advantages of hiring inverter on rent, such as:
