For the Northern Hemisphere， now is the summer, and it is very hot.
1. there are plenty of solar power
2. It is too hot to stay at home, how about go out for travelling?
So: a power inverter is very important no matter in home usage or for a travelling.
1. For home usage,
a) The emergency power outage
b) Connect to solar panel system or batteries to exchange the power for the appliances .
2. For travelling
a) It is a very advisable to take a power inverter when driving a car with family especially when taking the kids.
b) It is also very useful to take a power inverter when for a picnic.
So, how to choose a proper power inverter for home use and for the travelling ?
- How to choose a proper power inverter ? There are so many different size power inverters, also with so many different watts appliances, and we still need to power different appliances meantime. So, how to calculate the correct watts and amps, then to choose a proper Power Inverter is very necessary and important.From the point of utilization, it depends on the Watts(or amps) of what you want to run (find the power consumption by referring to the specification plate on the appliance or tool.)From the point of professional:One of the key difference between inverters is how much AC power they produce. Add up the wattage of each device you will run simultaneously, and make sure the inverter will supply sufficient AC power.
To select an inverter that has enough power for your application, add the watts for items you may want to run at the same time. Use the total wattage, plus 20%, as your minimum power requirement.
It is advisable to buy a larger model than you think you will need (at least 10% to 20% more than the largest appliance load).
For example, you want to power a computer, with a 17″ monitor, some lights, and a video.
Coffee Maker: 320 Watts LCD TV: 120 Watts Laptop: 100 Watts Total Needed: 540 Watts
Here some Information for the Common Appliances.
Note: the wattage’s given below are estimates. The actual wattage required for your appliances may differ from those listed. Check the namplate ont he appliance to determine the actual wattage required.
* Appliances and tools with induction motors (marked *in tables)may require from 3-7 time the listed wattage when starting. The start-up load of the appliance or tool determines whether an inverter has the capability to power it. Be sure to check the specific wattage requirements and operating instructions for appliances /tools to be used. Also, air conditioners are a very difficult load because of the high start-up surge. Use the locked Rotor amps to determine the start-up surge requirement.
(conversion formula: Watts/120 volts = Amps…….Amps*120 volts=Watts)
