Does my truck have a power inverter?

I am a professional, so yes. Required about $80 in material and 1 hr of my labor.
Material:
4/0 wire (25') $60
250 amp fuze block $18
250 amp fuze $6
Rubber grommets $2
4 Self tapping sheet metal screws $.85
Having the clock on my microwave and all my electronics operating as they should, priceless.

 

00 seems a bit light for 250A DC rating.

 

now you are gonna make me look at my receipt to see what I ordered when I did it last year...
Gee thanks lol

 

Correction, 4/0 was used on that. 2/0 was on the stereo amp (500 watt) I did at the same time.

 

good ones are not modified sinewave inverters, and no most things don't run well on modified sinewave inverters.

 

What electronics require a pure sine wave inverter?

 

Read it, the last two paragraphs are not really accurate, he leaves out how adaptors really work.

 

What's wrong about it. DC-DC converters are made for laptops, and as long as there's an external power brick the power going into the device is already DC at the correct voltage. The only problem is getting thick enough transmission wires to run higher power devices safely, as lower voltage necessitates higher current.

 

I get what you are saying, but unlike the author in the article who has a lot less experience and less education than I do, I can judge those last two paragraphs as inaccurate.

I have a lot of inverter experience, repairing them for a while. These are just switching power supplies.

A lot of modified sinewave inverters, even those branded with popular names are cheap Chinese junk. They produce harmonics not just into the air but also on the line which can shorten the life of the device. Some drivers notice this when the inverter is on and they turn on the am radio or the cb and hear nothing but static, then turn it off and the radio is quiet.

A lot of people install those cheap ones and hook up a fridge or a coffee maker and think that it is the truck that causes the fridge or the coffee maker to crap out, when it is the inverter. There was an issue with o/o on another forum going through coffee makers, two a month and they had the same type of inverter the the dealer they bought their trucks from installed. I told them to replace the inverter, some did and the problem went away. Those who didn't I told them to unplug the coffee maker when they are done brewing, and they did and never lost another. The element in the coffee maker wasn't going bad but the control unit was and that was becuase it derived its timing for the clock circuits exclusively from the line power frequency and when was seeing dirty power it would burn out.

the same goes for many power supplies for things like gaming units or laptops. These are also switching power supplies and a few of them use the line frequency for the timing of power supply switching circuit to maintain the voltage going out of it.

I could go on but it gets more complicated.

My advice is to get the best our sinewave inverter you can find becuase if it is properly installed it will last longer and be better for your equipment and allow them to last trouble free than a modified sinewave inverter or a cheap one.

 

I have a xantrax inverter charger. It runs anything I need and it also has the charger so when you get home you can leave the bunk heater running on low and the fridge stocked an not kill the batteries over a couple days. Love it.
