    Inverter not powering some things

    We just picked up our 2024 Influence and I have two 330W solar panels as well as a Go Power IC-3000 3000W inverter/charger. In addition I have added two 270 AH lithium batteries in place of the included lead acid batteries. From what I gather, the inverter has taken the place of the converter. I noticed today that the only thing the inverter powers is the outlets. It does not power the microwave (the outlet it is plugged into) or either of the AC units. I installed soft starts on both ACs and had hopes of being able to run one on the inverter. I checked the breaker box and there is no voltage at any other breakers other than the standard outlets when solely on the inverter. Does this mean they didnít hook up some things to the inverter? How would I go about adding the microwave and AC circuits on the inverter so I can use those?

    An inverter changes 12V DC into 120V AC

    A converter changes 120V AC into 12V DC (usually to charge your battery and run all your 12V DC items like lights, thermostats, LP detector and whatever else is on your DC load panel - the one with fuses).

    So you likely have BOTH a converter and an inverter.

    I guess in your case Grand Design chose to only power the outlets, or some of them.

    To power other devices, assuming battery capacity is available) would require moving the AC circuits you want on the inverter over to the inverter output. One way to do this is to install a separate inverter circuit breaker panel and move the now non-inverted circuits to that new sub panel. I did that in my rig but only have all the outlets (GFCI and non-GFCI) and my refrigerator (residential, 120V AC). I choose to run a generator when in need of lots of high amperage power for the microwave and air conditioners.

    I'm not qualified to say whether you set-up will power the microwave and air conditions either alone or in conjunction with each other. But I'd guess you'd need a lot of battery for that. I'll let others comment on that.

    Was the inverter installed by GD or someone else? On my Reflection, I have "inverter prep". When I wired in the inverter and transfer switch, the breaker box supplied power to the house AC outlets including the microwave. It does not power the air conditioner, I doubt if many inverter installs do. As @traveldawg says, the air conditioning uses a lot of battery power, in the neighborhood of 125 Amps per hour on my rig. That would eat up your storage in about 5 hours. If you want to run the A/C for an hour to cool down the coach, you could run a connection from your inverter to the coach's shore connection. You'd have to turn off the charger function, but you'd have power to all your devices. Do this carefully or you'll run out of battery.

    The inverter was installed by the dealer as aftermarket. The RV was prepped for an inverter. I guess I need to start tracing some wires to see where the inverter sends the power to the breaker panel. It’s pretty stupid the microwave isn’t on the inverter. What’s the point of having a 3000W vs 2000W inverter if the only thing on it is just the outlets? I get it, the microwave and ACs use lots of battery and probably quickly, but that is the reason for adding more solar panels and batteries. I’m not expecting to run an AC for hours and hours on the inverter but it would be nice to be able to run one for an hour or so to cool things off. I know it can be done because lots of people do it, I just need to figure out how to get those circuits onto the inverter.

    The reason I think the inverter is taking on the role of the converter is because it is an inverter/charger and charges the battery too and has AC in as well as INV AC out.

    yep. It sounds like you now have an inverter/converter. I got confused when I read inverter/charger. My bad.

    See if there is a circuit breaker for the new inverter/converter. There might be one. I'm not familiar with what GD does for inverter prep so no idea how they get input to the inverter part of the IC. And, like you said, you are going to have to trace the inverter's AC output to wherever it goes to see what is or isn't on inverter power.

    It isn't at all unusual for the microwave to be powered on a non-inverter circuit. Big class A's do that a lot, but they usually come with a lot of house batteries. But not so in the trailer world. Few, if any, 5th wheel rigs come with very much battery power to run heavy duty appliances.

    Trying to run an air conditioner from the batteries is possible, but not simple.

    An RV air conditioner draws about 1800W. Yours might be less. Based on that, you’ll be drawing at least 1800-660W or 1140W from the batteries when the air conditioner is running. 1140W is about 88A, meaning you’ll use up your 540AH in about 6 hours of full sun on a clear day. Then you’ll be recharging your batteries during the remaining 12 hours of full sun. Your air conditioner will run nearly constantly, so something has to give because you aren’t going to get 18 hours a day of full sun. If you run the AC for more than a few hours, you’ll start the next day with low batteries.

    The soft start devices don’t really gain you anything in letting you operate. Your inverter can supply plenty of power to start the air conditioner as can your batteries.

    If all you are wanting is a couple of hours in the evening to cool the trailer, you’ll probably do okay.

    Running the AC for a couple hours is exactly what I want the ability to do. I also need to be able to run the microwave from the inverter. In addition, I can set the amount of pass through amps on my inverter so if I’m connected to 20 amp service it will pull that but then kick in the rest from the batteries if needed. I guess what I really need to do is go from the inverter AC out to the main breakers on the panel so it powers everything. As it stands now, it obviously goes to a sub panel or something that only allows it to control the outlet circuits and not everything. Because the RV was inverter prepped I have no idea where the wires from the inverter go as all I see them do is go down into the belly from the front compartment. It is also prepped for a generator so I do have an automatic transfer switch for shore power/generator but that shouldn’t affect anything I wouldn’t think.

    Did the dealer ask you how you planned to use the system? My experience with dealers (the ones here in NH at least) is that they have a limited understanding and are more concerned with how much they can bill than giving the customer the functionality they need. There is much experience on this forum, and many have found solutions to provide your desired functionality. It is possible. For me, the best way was to learn from the experts here, and then dive in and do it myself, for many forum members that is the best way. If you don't want to do it yourself, I suggest you find someone outside your dealer to work with you.

    My trailer can do what you described, I have a Victron multiplus, 600 amp hours of lithium batterys. I can run the AC, watch tv, run the microwave, make Keurig coffee off grid.

    It was expensive but in my book well worth the cost and effort.
