Installing a fridge in our new truck?

Yeah, seems like. Just checked and seeks like I'm using its peak wattage. Only weird thing is that even nothing plugged in and I starting the truck engine while inverter is on, it beeps same way.

I'm just looking for new inverter to order on Amazon. What wattage would I need for 3.2 fridge, microwave, laser printer and coffee machine and not to hear that alerting noise? Fridge would probably run 24/7, others just as needed.

 

You need to add up your wattages and have some reserve on top. I would think you need a 2500 or 3000 watt inverter. The wattages of your AC stuff are printed on them. Google helps too.

Keep in mind laser printers are nothing like regular (inkjet) printers. Laser printers take a huge amount of power to start up. I tried this with a good 1500 watt and it didn't work. I read online how lasers use more power and prefer pure sine. I got a pure sine wave 2500 watt inverter but it cost about $500. Still, I can run anything now. I have coffee pot, Keurig, microwave, Brother laser printer and a couple other things like chargers.

 

Thanks a lot. I appreciate your time and information you provided.

 

Add all those wattages together. And do the math. I left a fairly simple procedure somewhere in page 1 or 2 about how to figure out how much juice you need because an appliance needs more power in a truck and If you want the inverter to last you need headroom

 

I bought and installed 3000w pure sine inverter and wanted to test it. While installing inverter I cleaned up all battery terminals as well. I left 3.1 mini fridge on overnight, however in the morning batteries were dead and truck wouldn't fire up the engine. I replaced all 4 batteries 1.5 years ago and truck was mostly sitting since then, however I would run the engine for an hour or so every 1-2 months.
Does this mean that it's time for the batteries to be replaced? And also, shouldn't inverter stop working at certain point, so it doesn't drain batteries.

No. Your inverter will keep pulling power (even more if anything is plugged into it). In the link I saw that it has a power button. So your gonna have to power it off while if the trucks gonna sit for an extended period. Based on the size of the inverter, your either gonna need an APU, a generator like Hurst, or cycle the engine every 4-5 hours.

 

Don't recharge the batteries too fast, or you will need batteries. Right now I don't think you need batteries. When you charge any battery, the slower the better. Charging too quickly will either shorten the life of the batteries, or fry them. If you charge slow and still can't start, hopefully you have a warranty

 

What's holding that micro in place from sliding off every other corner?

 

Ya my last truck was a freightliner century. I had one of those $150 dorm fridge from Lowe's. Removed the cabinet behind the passenger seat, slid it in there. Had a cheap $50 Wal-Mart micro, that wedged in pretty darn tight. Between top of freezer compartment and bottom of cabinet. Ran it off a heavy ### invertor i got from tool store at truck world in hubbard oh. Only problem was sometimes had to start truck if running tv, micro, and fridge at same time. But was just easier to shut off tv while starting micro.

 

Mine always beeped when starting truck. I figured the starter motor is a huge draw on batteries.
