Using a 3000w inverter and generator

So I just bought a new to me travel trailer that has 3 solar panels 3 batteries and a 3000 w inverter. Just wondering if i can use my Honda EU 2000 generator at the same time the inverter is being used, or is it one or the other?n New to the solar :)
Thanks

    No, not unless it is an inverter that has a "grid-tie" function, but I can't see someone going to the expense of adding that type of unit to an RV. They are meant for residential and commercial solar electric systems, and cost a fortune, and are complex to wire.
  • Hi oilerzchick,

    I did used to use power from both the inverter and the generator, but not in a way that allowed it to be combined.

    I did that by having a dedicated inverter outlet in the Kitchen.

    I also did it by having a way to power only the converter. Then I would run the rest of the RV from the inverter. This is useful when you do not have access to the shore power breaker, and there is only a 15 amp service to draw on.

    No. Even if that were possible, you'd run your batteries down in short order, even with solar.

    You can get another 2000 and do it.
  • No you cannot combine power unless it is a Victron Multiplus or Magnum inverter that has this option.
  • Mainly wondering if i could use the generator and inverter to have 5000watts to run my a/c if needed? Don't really want to buy a Honda EU3000 to run the a/c if i don't have too.

    What we do is run all the 120VAC items we want to run from the inverter which is connected to a calculated battery bank and all of the 12VDC items connected directly to the batteries.

    Where we camp has generator run time restrictions in place so we run off the batteries and hopefully don't drop our charge state below 50% before 8AM the next morning when we can run our generator.

    The only reason for the generator is to re-charge the battery bank in as quick of a time frame as possible. The only reason for the solar panels is help re-charge the batteries so we don't have to run the generator as much.

    This is what we would have to do here on the East side of the USA when camping off the power grid where the campgrounds usually have generator run time restrictions.

    The 3000W INVERTER will require a very large battery bank if you are planning on loading it down full load. This would be pulling 250 AMPS DC current plus losses from your battery bank if fully loaded down. That is alot of juice to pull...

    Your solar panels would have to produce a very large amount of DC current to run directly off the panels. The only good use for using the solar panels is to help charge the batteries during the HIGH SUN time of the day. A typical 120W SOLAR panel will only produce around 5 AMPS DC current when in high sun. High sun is usually only 5-6 hours a day...

    Need to do some good planning on what you want to do with your setup and beef up things accordingly...

    Just my thoughts...

    no. You posted in the Truck Camper section.
