For powering loads of over watts, you should connect the inverter directly to your car battery. This requires a 4-gauge power cable and draws power directly.

Run the wire from the battery location to the fuse and from the fuse to the power inverter location. Secure the wire with wire ties and electrical tape to whatever permanent medium is in the installation location. Mount the power inverter making certain all grounding instructions accompanying the unit are followed.

He holds a bachelor's degree in philosophy from Santa Clara University. Tips Cover the wiring with plastic conduit cover if installation will be exposed to weather. UL is the listing for inverters and chargers in mobile applications. They must meet strict vibration, environment, and thermal requirements that non-UL units do not. The main point being that the neutral and ground wires are bonded together within the inverter. All inverters that are not UL listed do not do this as it allows the inverter to be made at a much lower cost.
Carlson noted that inverters will occasionally shut down, but quality inverters do so without damaging themselves. If dust or cat hair, for instance, gets inside the inverter, it can cause the inverter to overheat.
Some higher watt inverters have an error code that shows what the problem is. The more you can use shore power, the better, as it prolongs the life of your batteries. This happens by keeping batteries fully charged, offsetting parasitic loads, and reducing the number of cycles. This ensures the truck will have enough juice to start.

They do add weight and cost to the vehicle. But, deep-cycle batteries were designed to be drawn down to a percent state of charge, or This gives you double to triple the amount of continuous power to run hotel loads. According to Carlson, not knowing what kind of inverter your driver is bringing in is why fleets often have a policy of not allowing drivers to outfit company trucks with their own inverters. And, we suggest you make it mandatory that your shop or outside dealer perform the installation.
How to Hardwire a Power Inverter to a Battery
When those conditions happen, just power up the APU for air conditioning. With this set-up, the only time the APU would need to come on is if the batteries drop to a low level. The length of runtime that the battery will provide largely depends on the kind of device you are running. If your appliance needs a steady supply of power for a long period of time, that can put a heavy load on the battery. Therefore it is not advised to use your car or truck battery in this situation. The battery can be easily drained to the point where it no longer hold the power necessary to start the engine.
This will prevent you from recharging the battery using the vehicle's alternator. Draining a starter battery like this on a regular basis will harm it and significantly shorten the expected life span. If you need to run a heavy load through a larger inverter from a car or truck battery, you should only do this while the vehicle is running. Otherwise we recommend you use a deep cycle battery, such as an RV and Marine battery. If you are using a watt inverter or larger, Marine batteries are preferable because they have the capability to withstand being drained deeply and recharged many times.
These deep cycle batteries should give you several hundred cycles of charging and discharging.

If you so, it can significantly shorten the life of the battery. If you need more power or longer runtime, you can connect several batteries together in parallel. Creating battery banks is a good alternative to buying a larger battery. Remember, when configuring batteries in parallel, it should done with 12 volt batteries of the same type as one another.
Using an inverter to generate power from a battery can be an invaluable resource for anyone who finds themselves away from traditional AC power sources. If you can, try to use a Pure Sine Wave inverter. The pure sine wave is better for applications, especially those that have sensitive electronic components.

The other option, the modified sine wave inverter is less expensive but good for simple applications such as radios. The difference is this: The pure sine wave is natural and the wave is curved. From peak to peak there is a full range of frequency in-between. Modified sine waves are rigid waves, only outputting the top peak and the lower peak alternatively, with no range in-between.
Our high end inverters are pure sine wave. We believe that's the best way to get the AC power you need. Choose Your Power Inverter. Name Should contain only letters, numbers, and ' -. Email Email address should be formatted user domain. Can I power a battery charger from an inverter to charge the batteries that are powering the inverter? No, as the charger pulls more energy than it puts out. So you will continually go into the negative, and eventually deplete you battery.
Can they be connected directly to a marine battery? How would this be done? Yes, there are 12 volt light bulbs meant to run off a 12 volt system, such as a battery. I would select a unit that meets your needs. A charger will pull more energy than it can put out as part of conversion process. So you will always be in the negative.
