Inverter

We have read that a 1000W inverter is adequate for running the refrig. during travel. Our big concern is if we travel 7-8 hours when we arrive we won't have sufficient power in our batteries to run anything and then if we can not connect to shore power would we defeat our purpose of keeping the refrig powered.

We have solar to charge our batteries currently.
Does anyone have options or ideas for charging the RV batteries as it appears we need to disconnect the charging to the batteries to use the inverter.

  • We have not tried it just wondering if it is possible. Everything we read seemed to say it wasn't possible but the explanation of the Converter helped a little.
    That sounds promising. Do you have any suggestions for installing an inverter like you have?
  • This is getting confusing.

    So, you DO have a regular gas refrigerator? Traveling with the gas on is fine. But, if you consider it unsafe, then don't do it.

    No, you don't have to shut off your solar when running the inverter. I thought you were talking about the converter.

    You want to run your GAS refer along with your MW? While you're parked?
  • Short answer, NO.
    A 1000 watt INverter will not power a microwave or coffeemaker IF they use more than 1000 watts.

    Check your microwave, most likely it is a 1100 watt model which actually draws 1200 or more, and my 12 cup coffeemaker uses about 1100 watts as well. A single cup model may only use about 700.
  • Are you just wondering or have you actually tried ?
    I have a 2000 watt inverter and a residential fridge. After traveling all day using the inverter and charging with solar my batteries are fully charged when i stop. I suppose if you can't get enough charge from the solar you could run your genset too.
  • We do have the option to run propane but understand it isn't real safe traveling with the gas on. We would like the option to run the inverter both while traveling and when boon docking but does this mean we have to shut off our solar when running the inverter.
    We would like to run the solar and the inverter at the same time but our understanding is you cannot do that. Ideally we would also like to run our coffee maker and microwave along with our refrig. Is this possible.
  • I believe the OP is confusing a CONverter and an INverter.

    To make is as short as possible.

    A CONverter is what your shore cord plugs into, it provides the power distribution from shore 120 Volt AC power to all you outlets, as well as providint 12 volt DC to the unit as well as the charger for your battery. It ONLY works when plugged in to shore power.

    An INverter is an appliance that draws power from your 12 volt battery and changes it to AC power for whatever device it is connected to.
    Inverters are commonly used by manufacturers to power a refrigerator in an RV or to a television. They are drawing power from the battery which must eventually be recharged to allow further function of the appliance.

    The "Loop" some have tried to create is to use the inverter drawing power from the battery, to power the Converter to recharge the power.
    This loop does not work because there is always a small loss when changing the form of power so eventually it always consumes more than it generates.
  • Are you using a residential compressor type refrigerator in the RV? Most RVs come with a refrigerator that runs on propane during travel and on electric when on shore power. An inverter is not needed to run these refrigerators.

    Why?
