Emergency Power Wiring Kit (for 2016-2018 Chevrolet Volt)
View All Inverter Kits & Prices | Frequently Asked Questions | Brochure (PDF)
(1200W Wiring Kit ONLY)
(1200W Wiring Kit with 90%
Efficient True Sine Wave Inverter)

  • Detailed Instructions (with photos) Included
  • Utilizes 12V accessory power system of the Volt
  • Provides backup power without needing to run the Volt’s gasoline engine*
  • Includes all hardware and accessories designed specifically for the Volt
  • Aside from a small notch in battery cover, no permanent modifications to the Volt are needed
  • Quick disconnect system allows for easy connection of inverter
  • Maximum continuous power supported: 1200W with 3000W surge
  • Installation Time: 30-45 minutes

The EVEX-1200W and EVEX-1201W are do-it-yourself** wiring kits to provide emergency backup power from your Chevrolet Volt. The kits are custom-designed for the Volt (model years 2016-2018), to allow for a hidden installation with power connector access through the storage compartment on the left-side of the hatch storage area

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

The EVEX-1200W is designed for a maximum continuous power of 1200W with 3000W surge. These power ratings are designed to work within the limits of the Volt’s 12V power electronics design. The EVEX-1201W is the same wiring kit bundled with a 1500W pure sinewave inverter - see note below.

Note: While a 1500W inverter can be used to help start appliances with higher start-up surge power needs, continuous loads should not exceed 1200W. This is a limitation of the Volt's DC-DC converter system, not the wiring kit. For this reason, if using an inverter larger than 1200W, we recommend using an inverter equipped with a power meter display, to properly monitor power usage.

Frequently Asked Questions
Do you have Gen 2 Volt Inverter kits available for inverters larger than 1200W?
At this time, we have chosen to only offer a wiring kit that supports up to 1200W continuous power.  While the wiring of the kit we provide can handle 1500W, the 1200W limitation 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 Volt can provide, ultimately resulting in a dead battery or damaged electronics within your vehicle. While a 1500W inverter may be used to help start appliances with higher start-up surge power needs, usage should be monitored to ensure continuous loads do not exceed 1200W. 
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 with only a 1000W inverter 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 continuously 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 Volt'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 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 a kit available for the Gen 1 Chevrolet Volt and Nissan Leaf, and hope to have kits available for other popular hybrid and plug-in vehicles soon, including the Chevrolet Bolt EV.  If you would like to be notified of when a particular vehicle has a kit available, please contact us.
