Cables Page for recommendations for each of the inverters we sell. “What happens when you put a 20 amp receptacle on a 15 amp circuit?” Someone plugs in a 20A load, and pops the breaker. A laser printer generally requires a pure sine wave inverter capable of surging at least 6.5 times the maximum wattage rating of the printer. Coil the television power cord and the input cables running from the 12 volt power source to the inverter. The cable size depends on the distance between battery and inverter, and will be specified in the Owner's Manual. When connecting the inverter to the battery always use an overcurrent protection device, such as a fuse or circuit breaker, and use the thickest wire available, in the shortest length practical. Cable size recommendations may vary among inverter brands and models; check the Owner's Manual for the model you purchase before you buy the wire for it. Do I need a Modified Sine Wave Inverter, or a Pure Sine Wave Inverter? What type of battery should I use (automotive or deep cycle)? Example: You want to power a computer with a 17" monitor, some lights, and a radio. Operating a Laser Printer with a Power Inverter. How do I connect two or more batteries together? They are also capable of withstanding repeated drains of power and recharging. AC Watts divided by 12 x 1.1 = DC Amps Chart of Estimated Watts Used by Common Appliances and Tools. A short circuit can damage your system, cause a fire and be hazardous to your health. If you need more length, it is much better to put it on the AC side (as with an extension cord from inverter to appliance) than on the DC side. If the bulb appears to be too bright, or fails to light, do not use the lamp with the inverter. This is caused by deficient filters in the audio system. Or you can use a battery charger plugged into an AC outlet to recharge the battery. Choosing which one is best from such a long list can be a chore. Click the Calculate button Place the inverter on a reasonably flat surface, either horizontally or vertically. It is recommended to install a battery isolator between the batteries. See our These fuses are CSA and UL listed. How long can I run the inverter on my battery? Most often the start up load of the appliance or power tool determines whether an inverter has the capability to power it. Not all fluorescent lamps operate properly with a modified sine wave inverter. Also insure that the antenna cable is properly shielded and of good quality. Enter the total Amp/Hrs of the battery or bank of batteries. For instance, a strobe rated at 300 watts requires an inverter capable of surging to 1200 watts or more. The inverter should not be installed in the engine compartment, due to possible water/oil/acid contamination, and excessive heat under the hood, as well as potential danger from gasoline fumes and the spark that an inverter can occasionally produce. For a 15-amp circuit, the safe load target is 1,440 watts; for a 20-amp circuit, the safe load is 1,920 watts. Pure Sine Wave inverters (also called True Sine Wave) are more suited for sensitive electrical or electronic items such as laptop computers, stereos, laser printers, certain specialized applications such as medical equipment, a pellet stove with an internal computer, digital clocks, bread makers with multi-stage timers, and variable speed or rechargeable tools (see " e) Reliably powers the following devices that will normally not work with modified sine wave inverters: We carry a full line of Pure Sine Wave and Modified Sine Wave Power Inverters here at DonRowe.com. If you wish to use those items with an inverter, then choose a Pure Sine Wave inverter. Amps x time = AH. var amph = document.getElementById("amph"); For instance, a laser printer rated at 500 watts requires an inverter with a surge rating of at least 3,250 watts. Fuses and circuit breakers to protect your inverter are available Cheers GMA Style 5-Amp Fast Acting Glass Fuse (5-Pack) The Cooper Bussmann GMA Series 5-Amp Silver The Cooper Bussmann GMA Series 5-Amp Silver Electronic Fuses are constructed of a glass tube with nickel-plated-brass end caps. Amps are important because it determines what wire size you need, especially on the DC (low voltage) side of an inverter. First make sure that the television antenna produces a clear signal under normal operating conditions (i.e., at home plugged into a standard 110AC wall outlet). Watts are basically just a measure of how much power a device uses, or can supply, when turned on. A fast acting fuse or circuit breaker will blow within milliseconds under short circuit conditions, preventing any damage or hazards. The battery can be recharged by running the automobile motor, or a gas generator, solar panels, or wind. Do not expose it to rain or moisture. We carry many different sizes, and several brands of power inverters. Length - 3.72 inches. Sine Wave, Modified Sine, and Square Wave - Say What? No other appliances, fixtures, lights, or outlets can be served by these dedicated circuits. Inverters come in size ratings all the way from 50 watts up to 50,000 watts, although units larger than 11,000 watts are very seldom used in household or other PV systems.
