The EVEX-1000L and EVEX-1000M are do-it-yourself** wiring kits to provide emergency backup power from your Nissan Leaf. The kit is custom-designed for the Leaf, to allow for a hidden installation with power connector access under the front hood of the vehicle.

The kit includes a fuse holder with fuse, heavy duty wires cut to length with soldered leads and pre-installed wire terminals, as well as a heavy duty connector set to allow quick connections to the inverter of your choice as needed.

The kit is designed for a maximum inverter size of 1000W with 2000W surge. This maximum size is designed to work within the limits of the Leaf’s 12V power electronics design.

Frequently Asked Questions
Do you have kits available for inverters larger than 1000W?
At this time, we have chosen to only offer a wiring kit that supports up to 1000W continuous power.  This is to ensure that the power draw from the inverter will work properly with the built-in power electronics of the vehicle.  Larger systems, combined with other electronics that are always running in your vehicle, may draw more total power than the Leaf can provide, ultimately resulting in a dead battery or damaged electronics within your vehicle.
I want to run a fridge or freezer off my vehicle, will this kit work?
The compressor of a refrigerator requires an initial starting current that is much greater than the current it will use once the compressor is running.  Refrigerators are quite varied in size and energy efficiency, and as a result, this starting current (also known as "surge current" or "surge power") can vary greatly, even among similarly sized refrigerators.  The ability for an inverter to provide this surge current can also vary greatly from product to product.  As a result, it is often difficult to know definitively if an appliance can be operated from a given inverter without simply trying it.
This kit has successfully powered a full-sized kitchen refrigerator having a nameplate rated current draw of 3.5 amps at 115VAC.  The methodology to label the power consumption of the appliance, however, also varies greatly.  This test was done using a 1000W pure sine wave inverter, with a rated 2000W surge capability.
As a general rule of thumb, people suggest measuring the continuous power of a fridge when the compressor is running, using a Kill-a-Watt power meter.  An inverter that can supply 3 to 4 times this measured power is typically sufficient to handle the initial starting current of the refrigerator's compressor.  However, as stated above, the only real way to know is to simply try it with the inverter you plan to use.
Will this void all or part of my vehicle's warranty?
There have been various discussions and posts on forums about whether or not a wiring modification such as this would void all or part of your vehicle's warranty.
The wiring kit only makes a connection to the Leaf's 12 volt battery terminals.  As a result, it would seem reasonable to conclude that any warranty issues as a result of this installation, if any, would be limited to the 12 volt system.
There is also the Magnuson-Moss Warranty Act of 1975 that states a dealer must prove that aftermarket equipment caused the need for repairs before it can deny warranty coverage. (See Edmunds.com article: What Voids your Vehicle's Warranty?)
This would suggest that only a small portion of your warranty could be voided, and only if the dealer can show it was this wiring kit that caused the need for repairs.
However, EV Extend cannot make any definitive claims as to whether or not installing this kit will void your warranty.
Do you have wiring kits available for other vehicles?
We also have kits available for the Chevrolet Volt, and hope to have kits available for other popular hybrid and plug-in vehicles soon.  If you would like to be notified of when a particular vehicle has a kit available, please contact us.
