2 AWG Gauge Red + Black Pure Copper Battery Inverter Cables Solar, RV, Car, Boat 12 in 5/16 in Lugs

Product Information

The cable sizes for the inverter and battery are not necessarily the same as those for the solar panel and battery. Refer to the proper documentation or owner’s manual for the recommended wire gauge and lengths. How to Calculate Inverter Wire Size Requirements Each end of the core should be crimped and set into an appropriate connector. Insulation and sheath Some cables come with a solid core instead. Solid core cables are used in buildings where cables are out of the way and won’t be disturbed.

Inverter cigarette lighter adapters are plug and play. Once plugged in your vehicle it should work. However you won’t be able to use the maximum power. From a 500 watt inverter, the lighter might pull only 250 watts. But if portability is your main prioerity,, then this should be an issue. It is hard to describe the difference in cables (ignoring the physical size) in words to determine what to look for and what to avoid. Youtube 'Vanlifers' don't help by saying things like "I am installing a Victron 12/3000 Multiplus, which has a 3000W inverter" and their fans hang onto every word as gospelThe units that are used to identify power inverter cables is in AWG, or the american wire gauge, which has been used in North America since 1857, and has since been the standard measurement for solid, nonferrous, round, and electrically conducting wires. Below are the typical sizes for power inverter cables We calculated our total power usage as 78Ah/day. We then add a 20% factor of safety to this figure to account for any days with higher power usage, giving us a total power usage of 94Ah/day.

In North America the AWG standard is most commonly used for stranded cable and expresses the Gauge together with the number of strands and their Gauge. For example, a cable specified as 16 AWG 7/24 has a size of 16AWG and is made up of 7 individual strands, each of 24 AWG. You will need to consider a couple of factors to help you decide between AGM and lithium batteries for your campervan. You should think about how long you plan to keep your van, how much of factor space and weight are in your conversion, and what your budget is. In theory you can install an inverter anywhere and from any distance from the battery bank. But the bigger the inverter and the further it is from the battery, the larger the voltage drop. In fact the voltage may plunge so low the inverter will not even run.

The cable rating will include a thermal limit, the amount of heat the cable can safely dissipate.

My approach would be to get an inverter large enough to run whatever single item you want to use (and a battery bank large enough to power that inverter).Yes you can use an extension cord with an inverter. If the distance between the inverter and the battery or appliances is too far, an extension cord will work. Just make sure the cord specs are suitable for the inverter and load.

By planning the installation ahead of time, you can determine where the inverter and batteries have to be so they can be as close to each other as possible. Doing this will reduce the amount of time required to configure the cables so they are in the right position. Conclusion The sizing gauges can vary depending on what you look at, but there are a few factors to consider and ampacity (current carrying capability) is just one of them. Voltage drop can be very important depending on the device (for an Inverter, it is far more important IMO than when specing up a B2B, for example) and heat (=wasted energy) is a key factor, as is efficiency. Suppose you have a 1500 watt 12V inverter, the WZRELB Pure Sine Wave. for example. The calculation is like this:

It may not be the most interesting or fascinating thing to do, it matters that you choose the right cable choice for the power inverter that you have decided to use for whatever purpose. The size corresponds to the wattage rating of inverters. As you can see, using 0.5mm is not sufficient for the task because it exceeds the ideal 3-4% voltage drop (6.45%).
