3000 watt cobra Power inverter installation?

There are charts online for gauge depending on the length and wattage.I have had a Harbor Freight 2000:3000 watt inverter for a year now and no issues.They now have one that’s pure sine wave for $299.

 

Put a fuse on the hot lead at the battery. I have a 3000 watt and used 4/0 gauge leads. Probably could have used 3/0. Would have been a bit easier to work with.

Here's what I bought:

4/0 AWG Gauge Red + Black Pure Copper Battery Inverter Cables Solar, RV, Car, Boat 4 feet 5/16 in Lugs

I had to drill the lug for the negative lead so it would fit the battery terminal. The hot lead went to the fuse:

Blue Sea Systems MRBF Surface and Terminal Mount Fuse Blocks

 

Just one of each. A 4/0 cable is as big as the lead from your battery to your starter. It'll do.

 

Just the cables.Harbor freight sells the cables as well.Just one.

 

With cobras keep in mind if you put a heavy load on them such as a microwave they get VERY hot even compared to other inverters i have used, make sure where ever you mount it has at least 6 inches of clear space behind and infront of the unit. Also dont mount it near the hot air vent on a bunk heater. Ive had them actully melt trim and in one case a pair of boots just from how hot the exhaust got when under heavy load for a while.

 

Probably not a bad idea. Mine is an AIMS 3000 watt and it is so big my seat touches it when I slide it all the way back. Also, some of them have a voltage meter. Mine doesn't and I wish it did. I did buy the remote on/off switch and mounted it in the sleeper. I would do that again.

Just make sure whatever you buy it is a pure sine wave inverter. The cheaper ones will burn out your electronic toys over time.
