Sizing an inverter is nothing but simple math. A TV may require 150 watts and the VCR you want to add with it may require only 100 watts. Just simply add the wattage requirement for all the appliances that will run at the same time. The answer is 250 watts for both the TV and VCR to run. However, it is recommended to always go slightly bigger (25%). This will ensure that the inverter will power all appliances safely. For more information, visit our Inverter Sizing page.

To determine this, the maximum amount of energy needed to run your electrical appliances (microwave, washer, television, lights, etc.) at the same time is calculated in terms of wattage. Every inverter is sized according to wattage – it is better to go over than not have enough watts.

a rule of thumb (leaning on the high side), an inverter will require 10% of its continuous wattage rating from a battery. Example: A 300 watt inverter providing 300 watts to an appliance will require 30 amps from the battery. The same inverter providing 150 watts to an appliance will require 15 amps from the battery.

Yes, both sine-wave and modified sine-wave inverter output will operate a computer. However, some monitors and laser printers can only be powered by true sine wave output.

a) Output voltage wave form is pure sine wave with very low harmonic distortion and clean power like utility-supplied electricity. c) Reduces audible and electrical noise in fans, fluorescent lights, audio amplifiers, TV, Game consoles, Fax, and answering machines. e) Reliably powers the following devices that will normally not work with modified sine wave power inverters: We carry a full line of Pure Sine Wave power Inverters.

Using thicker power and ground cables will allow your amplifier to draw the juice it needs from the battery more easily. You'll find all the power and ground cable you need available in our online Installation Store. Before you can decide on the appropriate gauge wire for your installation needs, you need to figure out the current demand of your system. To do that, you must ascertain the approximate current draw (in amperes) of your amplifier (or amplifiers).

The main purpose of your power supply is to run your trains. To run your train your power supply must supply energy for your locomotive, smoke unit, sound system , and any lighted cars. You may also need power for accessories like switches, street lights, building and house lighting or any other accessories. Your TOTAL POWER REQUIREMENTS depends upon the number of locomotives or motors, and ALL OTHER items that require electricity. The length of the track is not a factor.

The small power inverters (350 watts and under) come with a cigarette lighter adapter, and may be plugged into your car's lighter socket. The small units also come with cables that can be clamped directly to a battery. If you want an DC to AC power inverter that will plug into your cigarette lighter, you must choose one that is 350 watts or less. Larger DC to AC power inverters (500 watts and over) must be hard-wired directly to a battery.

AC inverters have built in voltage input protection that allows for safe operation of your AC powered item. Let's say you are trying to run a 12Volt TV That comes with an AC adapter. You would have two ways you could power that TV with your DC pedal power bike generator. First you could hook up your pedal power bicycle generator directly to your 12V Television TV. The problem is that your TV might blow up in smoke if you provide it with 10 Volts or 14 volts.

Small Power Inverters usually include a DC adapter which can plug right into a car's cigarette lighter, or other 12V DC outlets. Inverters that are 300W or larger usually connect directly to a battery via batter cables, or thick 0-4# wire. Always, follow the manufacturer guidelines. Inverters must be installed in a dry place. Never install inside an automobiles engine bay, or outside where rain or moisture can reach the unit.

A small matchbox size inverter (12v) will power up to 8 meters of Glow Wire, either as one length or seperate lengths wired to the inverter in parallel. Larger inverters are available to power longer lengths of Glow Wire. We can provide inverters that will power up to 1000 meters of Glow Wire!

The power rating used with microwave ovens is the "cooking power" which refers to the power being "delivered" to the food being cooked. The actual operating power requirement rating is higher than the cooking power rating (for example, a microwave with "advertised" rating of 600 watts usually corresponds to almost 1100 watts of power consumption). The actual power consumption is usually stated on the back of the microwave.

Many people use the wrong size cable for their systems but working out what power cable you need is actually very simple. Add all the ratings together. ie total each amp so a 2x50wrms amp would be 100, then add the totals together. This gives you a number representing the current draw, in amps, of your system. Then match the current with the length of the cable in the following table to give you the correct size cable to use.

Short Answer: The size power inverter you choose 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). We recommend you buy a larger power inverter model than you think you'll need. For this application, you would need a 500 W power inverter, and should give some thought to a larger one, as there will likely be a time when you wish you'd bought a bigger model ..
