Re: Emergency Power Wiring Kit (for Nissan Leaf)

This wiring kit is pretty slick for a permanent clean installation, but if all I want to do is occasionally use a 1000W inverter when there is a power blackout (i.e. 1x or 2x/yr), is there anything wrong with just connecting my inverter to the 12v battery with jumper cables?

It is fine to hook up temporary. Just connect the negative side to the "engine" block or someplace other than directly on the battery. Also make sure you have heavy enough wires to feed the inverter and they have a good connection. You can tell if they start to get warm at all they have a poor connection at that point. That is the way I use mine now since I can move it between vehicles.

Since EVExtend is currently sold out, I'm planning on doing this, but I'm nervous about just using the inverter alone without anything else from the kit.

The EVExtend kit has a fuse. I don't know a lot about electricity but I would think having a fuse is a good idea. What voltage (do you measure fuses in voltage?) fuse would you need for the leaf, and where would you put it? (I'd also like to be able to use this on my Prius Plug-in, I assume the same fuse would work for both cars.)

The EVExtend kit also says it has:
EVEX-1000L Brochure wrote:High current DC connector for quick inverter connect when emergency power is needed

What is that? Is that just a description of the 4AWG and 8AWG wiring for the positive and negative connections, or is there an additional connector to somewhere else?

If your inverter fails, could it damage your car? If so, a fuse is a good safety feature. Select fuse current to match your inverter.

Anderson SB50 connectors are inexpensive and rated up to 50A. These would be a good choice for a quick-connect port. Buy two identical connectors. Wire one inside the car with 4 gauge stranded wire and a suitable fuse, Wire the other to your inverter. Use cable ties to hold the car connector in place so it doesn't vibrate when driving.

Here is one vendor, but many people sell these connectors:

If you buy SB50 connectors, you must either buy the housing and pins separately or buy the kit with both housing and pins. Don't get fooled if you see housings for sale cheap without pins.

It's recommended to crimp the pins with a fancy tool, but you can also solder them. Just be careful to avoid getting solder on the contact end of the pin.
