A power inverter converts DC power into conventional AC power allowing you to use your favorite devices when an AC outlet is not available. Simply connect an inverter to a battery source, plug your appliance into the inverter and you're set!

Different devices require specific wattages to run correctly and efficiently. Please use this easy formula to determine the correct size inverter:

AMPS x 120 = Watts

Example: 15 Amp Cooling Unit X 120 = 1800 Watts

Please refer to our estimated watts to help you find the inverter that is right for you.

Keep the cables between your inverter and batteries as short as possible. This will help your batteries perform their best and keep the inverter's signal clean. The cables that come with the inverter are "rated" or good for up to six ft. If you plan on going over six ft., drop down to a larger gauge cable. Please call us if you are still unsure. This is pretty important stuff that should NOT be overlooked. If the cables between your battery and inverter get hot while under heavy load, then you should use heavier cables.

Yes, no problem. If cables need to be run, it is best to keep inverter as close as possible to batteries. Use extension cords on the output side (Vac output) rather than extending the Vdc cables. Tip: Contractors often need to mount the inverter in the back of their trucks. In a case like this it would be best to mount a secondary battery near the inverter and wire it to the primary truck battery. Vac extension cords should not exceed 200 feet or you will have signal loss

The run time depends solely on the amount and size (capacity) of your batteries.

FORMULA:

· Total the amps on your batteries and divide by 12. Take that number and set it aside, we'll get back to it in a moment.
· Total the amps on the devices you will use on the inverter, add another 1/2 amp for the inverter itself.
· Take THAT total and divide into the first number you came up with.
· The result will be your runtime in hours. The more batteries you put in parallel the longer runtime you can expect.

The low voltage alarm will sound when the DC source falls below 10 volts and the automatic shutdown will power off the inverter. This is done to save your battery(ies).

My inverter's fans won't come on
Good! On all our inverters over 1000 watts, the fans are connected to a thermal switch which will only allow the fans to come on when they reach a certain temperature. This helps keep your batteries holding their charge longer, and also makes it QUIET! Hooray!

No. Treat your inverter like you would your TV. You wouldn't put your TV outside in the rain, please don't leave your inverter there either. Be aware of lighting storms. If struck, your inverter would go into a permanent overload state and may even smoke it. If using in a marine environment, try to keep it tucked away underneath, in a dryer area.

Most of our customers prefer to use deep cycle marine batteries with their inverters. A few advantages are:
· Delivers higher peak amps faster than conventional batteries
· Provides up to twice the life of conventional batteries
· More consistent voltage across the discharge curve
· Superior cold and hot weather performance vs. conventional batteries

We suggest Tangos deep cycle batteries, they work extremely well with Tangos power inverters.

The following three paragraphs are for TANGOS Batteries

If your battery application requires more starting power or reserve capacity you can install multiple batteries together in parallel by connecting the like terminals together (positive to positive / negative to negative). Each time you add a battery in parallel you increase the CCA and Reserve Capacity, the voltage remains at 12 volts. For example, two TANGOS® 34/78's in parallel will provide 1600 CCA and 208 minutes reserve. Three in parallel provides 2400 CCA and 312 minutes of reserve. If you have any questions about multiple battery installations, contact our technical support team.

Suggestions for connecting batteries in parallel

· Use batteries of identical make, model, and age.
· Make sure cable gauge is sufficient to handle the higher current flow.
· Prevent cables from shorting (do not allow them to rub against the vehicle body).
· Use only high quality connectors, clean all contacts prior to installation.
· Periodically check all connections for snugness.
· If you are unsure of this procedure, contact your automotive service center.

Battery installation tips

· Ensure that the battery is properly secured to prevent movement or vibration wear.
· Do not over tighten the hold down bracket
· Replace any cables and connectors that have corrosion, rust, or other damage.
· Do not install batteries in a non-ventilated or sealed compartment.
· Do not lift or handle the batteries by the terminals.
· Do not over tighten terminal bolts

Modified sine wave power inverters are more portable than pure sine wave power inverters, lighter, and lower in cost. If your device will handle voltage fluctuations, a modified sine wave inverter should be considered. Most devices that people typically wish to power will work fine with a modified sine wave inverter, as a precaution, please contact the manufacturer of your device to determine if it is compatible.

Pure sine wave power inverters motor's run cooler, last longer and provide very clean power like you would receive from a power company. Devices such as laser printers, digital clocks, and most medical equipment require a pure sine wave inverter to run correctly. As noted above, as a precaution, please contact the manufacturer of your device to determine if pure sine wave power is required.

Here are some examples of the range of nameplate wattages for various household appliances:

Clothes iron = 1000–1800
Microwave oven = 750–1100
Personal computer

CPU - awake / asleep = 120 / 30 or less
Monitor - awake / asleep = 150 / 30 or less
Laptop = 50

Radio (stereo) = 70–400
Refrigerator (frost-free, 16 cubic feet) = 725
Televisions (color)

19" = 65–110
