    Inverter Trips When Keurig CoffeeMaker Used

    We had a 2000 Watt inverter installed in our brand new 2024 Imagine 17MKE. It was pre-wired at the factory, with the inverter installed at the dealership. The first time we used the TV, the inverter tripped and would not reset. Back to the dealership we went. They said they installed a new plug on the inverter. Then we went on a one night camping trip a few days ago. In the morn, we turned on the Keurig Mini Plus Coffeemaker. As soon as I touched the brew button, the inverter made several loud beeps and tripped. What happened??

    Thread moved to Electrical Systems and Wiring.

    The TV is a relatively low-draw appliance. The Keurig has a resistive heating element which, along with toasters, etc., are high-draw appliances.

    It takes a pretty stout battery and wiring to handle a load like that. It draws 1470W, which is going to be well over 100A from the battery. Itís highly likely the dealer didnít upgrade the wiring to handle that kind of load, so you see a voltage dip and the inverter alarms.. Dealers in general are a poor choice for upgrades like that.

    In general, itís not very practical to run resistive heating items from an inverter unless you have a significant battery bank and a means to recharge it.

    Are you referring to the wire that is left for "inverter prep"? I was going to ask my dealer to install an inverter in my "inverter prep" trailer.

    Too much draw....what else was on 120 when you tried to run the Keurig?

    Really just not trusting a dealer to do the installation properly in general. I don’t know that the 17MKE has the inverter prep.

    We use to run an electric frying pan off an inverter circuit. Every time it kicked on our inverter (2000 watt Xantrex XC with tons of battery(s)) would alarm with an overload message but nothing would trip. And if we had the electric coffee pot along with the electric pan on that circuit the inverter alarm would chirp every time the coffee pot cycled to keep the brew hot.

    I took the outlet we use for the electric cooking pan off the inverter. Now no more alarms.

    I need to ask if you have a Lithium (LiFePo4) battery, or a Lead Acid battery powering your Inverter.

    In either case, It sounds like your battery is not powerful enough to run your Inverter.

    Presuming that your Kureg actually draws 1470 Watts, You would need at least one (probably 2) 100ah Lithium batteries to power that load.

    When you upgrade to the Lithium batteries, you need to make certain that your cables running from the batteries to the Inverter are large enough to safely carry the load. Also, once you add the Lithium batteries, be certain to install the appropriate sized fuse as close to the battery as practical to protect the cables and Inverter.

    There is a lot of information on batteries and Inverters in the following thread:

    Be sure to click on the embedded links for detailed information on Lithium batteries (LiFePo4).
