i want to put a fridge or cooler,microwave in my volvo 670

I know that the coolers are rough on the batteries. I have never had a fridge, but am looking to put one in this weekend. This is the 1st truck that I ever had a inverter in.

 

It will drain the batteries as will anything some trucks have a low voltage sensor that sets off an alarm then it will shutt off all accesories untill you restart the truck to recharge the batteries.

My trainer had a fridge with freezer, microwave, tv, play station, 12 volt cooler, then I plugged in my laptop, his cell phone and my cell phone it would last about 8 hours before the alarm would come on.
If you run the microwave unplug everything and idle the truck to keep it in enough juice to have full power.

You will need atleast a 2500 watt inverter to run everything I would recommend to buy the biggest you can afford you will want to put in an inline circuit breaker close to the battery incase you have a problem with the power wires. That way you will not burn up the truck if a short happens.
Plot usually sells the 2500 watt for 199.00 if you look around you may be able to buy one at a place like harbor freight for less it is a local tool store here in my area and they have stores in alot of areas.
I was told it would be better to buy at a plot because of the amount of truck stops that are out there. That way if it goes out prematuraly you may be able to exchange it.

Even with the most carefull installation driving down the road may wear through the insulation of the power wires so check them monthly if you see one getting thin replace it before anything goes wrong.

But I still do not recommend running the microwave with other things running it will not hurt to unplug the fridge for 3-15 minutes just remember to plug it back in.

 

Thats great advice! I will have to call my hubby and tell him that! We just bought a fridge (coleman I think) for his truck- Walmart camping department - $85! It gets cold enough to almost freeze a coke.

 

My Hubby has a cooler microwave Tv ,Playstation , lap top printer and cell phone all on the inverter his company made him take his truck to the dealer to get it installed to made sure it was done right

 

Youst check with your companies policies for inverters..........
Some companies limit the watts of inverters installed in trucks....
My company limits them to 1500w

Check before you invest and throw away the reciept.......
