Many small inverters watts and under come with a cigarette lighter adapter, and may be plugged into your vehicle's lighter socket although you will not be able to draw more than to watts from the cigarette lighter socket. The small units also come with cables that can be clamped directly to a battery. If you want an inverter that will plug into your cigarette lighter, you must choose one that is watts or less. Larger inverters watts and over must be hard-wired directly to a battery. The cable size depends on the distance between battery and inverter, and will be specified in the Owner's Manual.
The easiest way to install a car power inverter is to simply plug it into a 12V accessory outlet. These outlets have traditionally been used for cigarette lighters, but a lot of new vehicles eschew the lighter entirely.
Since the cigarette lighter, or 12V outlet, is tied into a circuit that typically includes other electronics, there is a limit to how much power you can draw from it.
For that reason, a lot of cigarette lighter inverters artificially limit the available wattage when using this type of connection. These plug-in inverters are great for laptops and other small electronic devices. One way to permanently wire a car inverter is to either tap into power wire or go straight to the battery.
How to install power inverter?
After you tap into the battery, an in-line fuse will ensure that nothing melts down or catches on fire when you switch on the inverter. If you tap into an existing power wire, you could easily end up with the same set of problems you deal with in plugging into a cigarette lighter socket.
Some fuse boxes are located under the hood, but a lot of them are conveniently found somewhere under the dash. You can either install a new fuse in the empty slot and tap into the back of the fuse box or use a spade connector to plug directly into the front of the fuse box.
What does a power inverter do, and what can I use one for? How do I hook up the Inverter? What size cable should I use, and is it included? What is an overcurrent protection device? What type of battery should I use (automotive or deep cycle)? If you don't find your answer here, Read our Power Inverter Blog. The maximum length generally recommended is 10', and shorter is better. 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. Power Inverters - How to install a DC to AC Power Inverter Yes. There are two ways to use solar without batteries: 1. Grid-Tied. This is connecting your solar panels directly to the electricity grid using a DC-to-AC "grid-tied" inverter. The inverter converts the DC output of the solar panels to AC electr.
Adding a new fuse looks cleaner, but plugging in a spade connector is a little easier. If you don't include a fuse somewhere in the circuit, you could end up with a fire inside your vehicle should anything go wrong. When getting power from the fuse box, you should also check to see whether the connection always has power, or if it only has power when the ignition is on.
If you want to be able to plug into your inverter at all times, you'll want a connection that is always hot, while using one that's only hot when the ignition is on will prevent your battery from accidentally going dead. Take care not to cross the wires at any point. Cross-wiring the electrical circuit will damage the power inverter, and may cause an electrical fire.
Depending on the Wattage rating of the power inverter, the power inverter may generate excessive heat. Keep the power inverter away from any flammable materials. A power inverter inverters is a means to supply electricity for devices that use household voltage and current when only a DC power source is available. Connecting a power inverter is useful for portable electrical power; however, you can use a power inverter for more permanent uses as well.
Using the screwdriver, loosen the retaining screw on the power inverter Positive red wire insertion socket.
Insert wire end firmly into wire socket, and tighten screw so that the Positive lead wire is firmly in place. Loosen retaining screw on the Negative black wire insertion socket and insert the end of the second wire firmly into the socket.
Tighten the Negative wire insertion socket screw so that the wire is firmly in place. You might find it practical to get a small Pure Sine Wave inverter for any "special need" you may have, and also a larger Modified Sine Wave inverter for the rest of your applications.
How do I hook up the Inverter? What size cable should I use, and is it included? Many small inverters watts and under come with a cigarette lighter adapter, and may be plugged into your vehicle's lighter socket although you will not be able to draw more than to watts from the cigarette lighter socket.
The small units also come with cables that can be clamped directly to a battery. If you want an inverter that will plug into your cigarette lighter, you must choose one that is watts or less.
Larger inverters watts and over must be hard-wired directly to a battery. 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.
See our Cables Page for recommendations for each of the inverters we sell. NOTE: These are general recommendations for inverters that utilize a single cable set one positive and one negative cable only and may not be correct for all inverters or applications. Additionally, some inverters require two or more cable sets and therefore may require a different cable size than listed.
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.
Nov 13, The utility provided by a good power inverter is especially useful to salesmen, truckers, and other people who spend a lot of time in their vehicles, but a car power inverter can also be a lifesaver on a long road trip, camping excursion and in a lot of other circumstances.

Cables with battery terminals ring terminals or stud terminals to hook up your inverter are available here.
What is an overcurrent protection device? Why do I need one? Batteries are capable of supplying large amounts of current, and thousands of amperes could be present if a short circuit were to occur.
A short circuit can damage your system, cause a fire and be hazardous to your health. Incorporating an overcurrent device is an effective line of defense against a short circuit occurrence.
An overcurrent protection device is typically a fuse or circuit breaker that goes inline on the positive cable, between the inverter and battery, to protect your system.
A fast acting fuse or circuit breaker will blow within milliseconds under short circuit conditions, preventing any damage or hazards. It is important to appropriately size your fuse or circuit breaker for both your inverter and cables.
An oversized fuse could result in cables exceeding their ampere capability, resulting in the cables becoming red-hot and dangerous. Consult your owners manual for the recommended sized fuse or circuit breaker and cable gauge for a safe installation. Fuses and circuit breakers to protect your inverter are available here. What type of battery should I use automotive or deep cycle?
How does a power inverter hook up
Small Inverters: Most automobile and marine batteries will provide an ample power supply for 30 to 60 minutes even when the engine is off. Actual time may vary depending on the age and condition of the battery, and the power demand being placed on it by the equipment being operated by the inverter.
If you use the inverter while the engine is off, you should start the engine every hour and let it run for 10 minutes to recharge the battery. If you do not have a deep cycle battery, we recommend that you run the engine of your vehicle when operating the power inverter. When operating the inverter with a deep cycle battery, start the engine every 30 to 60 minutes and let it run for 10 minutes to recharge the battery.
Installing a Power Inverter in a Car or Truck
When the inverter will be operating appliances with high continuous load ratings for extended periods, it is not advisable to power the inverter with the same battery used to power your car or truck. If the car or truck battery is utilized for an extended period, it is possible that the battery voltage may be drained to the point where the battery has insufficient reserve power to start the vehicle.
In these cases, it's a good idea to have an extra deep cycle battery for the inverter installed close to the invertercabled to the starting battery. It is recommended to install a battery isolator between the batteries.
How long can I run the inverter on my battery? You can also use these formulas to calculate how long your appliance will operate on your battery. Tip: Deep cycle marine batteries generally have the highest reserve ratings. They are also capable of withstanding repeated drains of power and recharging. Doing so will shorten the life of the battery based on most battery manufacturers recommendations. Note: If you intend to use power tools for commercial use, or any load of W for more than 1 hour regularly between battery recharging we recommend installing an auxiliary battery to provide power to the inverter.
This battery should be a deep cycle type and sized to meet your run time expectations with the engine off. The auxiliary battery should be connected to the alternator through an isolator module to prevent the inverter from discharging the engine start battery when the engine is off.
