The first thing you will need to recognize is what you are planning on running in this time of urgent situation. The lesser the items or the smaller the amperage, the smaller or least exclusive inverter will be needed. I will give a chart of items and their average power makes use of below followed by a simple formula that will give you a consideration of the size of inverter you will require.
Electric Chain Saw: 1700 Watts
Electric Circular Saw: 1600 Watts
Home Stereo: 350 Watts
Mini Microwaves: 1000 Watts
1/3 inch HP Submersible Pump: 920 Watts
Reciprocating Saw: 720 Watts
1/2 inch Reversible Drill: 620 Watts
Coffee Maker: 600 Watts
Transportable Vacuum: 525 Watts
Electric Garden Tools: 475 Watts
Ten Speed Blenders: 450 Watts
3/8 inch Variable Speed Drill: 320 Watts
Twenty inch TV/VCR Combo: 300 Watts
12 inch Speed Fan: 200 Watts
Computer/Printer/Fax: 150 Watts
Quartz Halogen Spotlight: 100 Watts
Mini Stereo/CD Player: 50 Watts
Laptop computer Computer/8 inch TV: 38-45 Watts
Cell Phone/Camcorder Charger: ten Watts
14 Volt Cordless Drill Charger: 8 Watts
Stackable Washer/Dryer: 2500 Watts
Orbital Sander: 400 Watts
If the appliance you are planning on using is listed in watts, go ahead & use that number. If it is listed in amps you need to make use of this easy formula: volts (120) X amps (listed on tool) = watts. This will give you the quantity of watts the electrical device will be using. So in the event you had a three amp appliance, & you desired to find the watts, the formula would be: 120 (volts) X three (amps) = 360 watts.
You would then sum all of the watts that you will be using and come up with a number. Let’s say your whole watts usage is 500 watts. If that is the case it would be a lovely suggestion to receive a 750 watt inverter. Always receive a bigger size than what you think you will require, it may come in useful.
Your next step will be to decide where your power supply is going to come from. If it is for urgent situation there is an outstanding chance that it will be coming from a battery connected to your vehicle or you could be a small better prepared & have a bank of batteries connected in a parallel fashion.
The last thing you need to know about Three Phase Lighting Inverter is how long your power will supply (battery) last before it needs recharging. First you will need to identify the wattage of all the appliances. Let’s say they have 480 total watts of power being used, & they are jogging our inverter off of a 12 volt battery attached to the automobile. Next they must convert this number so that they know how plenty of amps are being used. They do this by taking the watts (480) & dividing it by 12 (volts of the battery) & come up with 40 amps. The formula is: watts / volts = amps. If they have a 120 amp hour battery they would divide 120 (amp hours) by 40 (amps) & get three hours before the battery is dead. It is suggested not to drain a battery below 50% of its capacity so you may need to divide the three hour in half giving you one 1/2 hour before beginning the automobile up to recharge the battery.
