1000 watt Inverter and coffeemaker

I have a Xantrex XM 1000 (watt) inverter that came with the 2016 Greyhawk. I have tried using a 800 watt coffeemaker that uses Keurig K-cups. When I turn on the coffeemaker, the inverter turns off for a few seconds and then resets. I have two Trojan 105 golf cart batteries that power the inverter. Has anyone had any success using the 1000 watt Xantrex to run a small wattage (800 watts) coffeemaker?
I think the answer is to get a larger inverter -1800 watts at least. Xantrex makes one that will be an easy replacement. The new inverter remote will fit exactly where the original one is in the control center. All the wiring would be the same if the DC wires from the batteries are heavy enough. Any suggestions?

Are they 2 6 volt batteries 105Ah or 2 12v 105Ah batteries? Even though the coffee maker is 800watt it probable pulls more than your 1000w inverter can handle or you don't have juice in the batteries to handle the load. If you have a Watt-o-meter you can tell what the coffee maker peaks at. You can get one for less than $20.

You should verify that the issue is not excessive voltage drop to the inverter. If the inverter is far away from the batteries and/or the wires are too small, I could see that being a problem when you are drawing that much current. For example, to run the coffee maker, your inverter is going to draw roughly 70amps from your batteries.
So, check wiring (as well as tighten connections).
Measure the DC voltage to the converter as you load it down to see how much it drops.

x2 on DanNJanice's advice.

A coffee maker is a straight resistive load and your inverter is rated for 1000W continuous so that part shouldn't be the problem. I checked quick and it cuts out on low voltage at 10.5V DC input - I would start as suggested on checking voltage drop at the input of the inverter.

You might invest in a stove top coffee maker?

In my work van I also was looking into what it would take to make a cup of Kuerig coffee. I don't know the rated wattage of my Kuerig but it peaked at 1200-1300 watts for about 2 seconds and then leveled off to the 750-800 watt range. I also looked into a Xantrax inverter and even though the surge rating on the 1000 watt inverter covered this, Xantrex tech help said surge ratings are milliseconds not seconds. They said it may work but to expect a short inverter life. I suspect your issue is more voltage drop like the others have said which is why I was asking about your battery bank but I wouldn't rule out the surge either. I quickly realized the cost of a mobile Kuerig coffee cup was more than I was wanting to spend at the time.

Response from OP

The Trojan batteries are new and are 6 volt golf cart batteries. they were fully charged when i attempted to use the coffeemaker. I will check the wires from the batteries to the inverter. The length of the wires "should" be ok if Jayco did the installation correctly. I would think Jayco used wires less than 5 feet long. Thanks for the responses!

Have any Greyhawk owners with the Xantrex XM1000 inverter had any experience trying to us a coffeemaker with this inverter?

But isn't the inverter only setup to run the TV. Greyhawks used to come with a 400 watt, but that is no longer made, thus the switch to 1,000.

Wire may be sized accordingly. Just sayin'.

I'm with Murff.


Heating water with battery power is a mis-application of resources!
