Inverter Upgrade

2007 Winnebago Voyage 35L just upgraded to lithium, new converter etc. Now I would like to upgrade the inverter from the 600 watt to about 2000. The 600 watt powers the front TV, two front outlets, and the rear TV. How hard would it be to power all the 15 and 20 amp breakers on the load center? Just want to power the outlets, possibly the microwave. I know a little about electrical stuff, but far from an expert. Is this something I could do myself? All
Ideas and input appreciated!

    Thanks for the responses. After looking I may just leave it as is except I would like to power the outlet by the bed for my CPAP at night. Does anyone have a schematic or picture of how the inverter is wired into the 120 volt load center? I’ve looked at the wiring manual from Winnebago and can’t figure it out.
    Why not just install a new outlet and wire it to the inverter?

    By the way, I have 50 amp shore power and 350 amps in lithium house batteries.

    Too bad you didn't just upgrade to an inverter that was also a charger (converter). Two birds with one stone. I agree with Bruce Brown, that you should maybe upgrade to a 3000 watt inverter so that you can for sure use the microwave. It would involve some wiring, but there are many on here who could help.

    Good advice offered above.

    The only thing I would add is we have a 2000 watt inverter and our microwave does NOT like running on it. It'll run but it's not happy about it, to the point we simply don't do it.

    The simple way is to plug in the shore power cord to the inverter, while turning off the converter. Fridge set to propane.

    If that works out well, then add a sub panel for the items you don't wish to power from the inverter.

    Is the RV a 30 amp service?

    How many amp-hours of battery bank do you have?

    As long as you learn and follow the basics of 120V wiring codes so that the change over is safe then it's reasonable. Keep in mind that a 15A AC draw is about 165A DC which is a large battery discharge with the inverter. So other factors like battery capacity, how to recharge them etc are factors. Likely your 600W inverter DC wires are inadequate.

    ie Look at the big picture and your usage to see if it meets your obectives.
