Just a "Back in the olden days comment" (early 70's) when I was learning about electricity, we were taught that AWG stood for "average wire gauge". Now days, everyone seems to refer to it as "American wire gauge". Anyhow, great informational video as usual Ray.

Maybe it is referred to now as American wire gauge because pretty well the rest of the world uses metric these days. MM2 square millimeters for wire gauges. However, since Canada is so close to the USA and a big trading partner, we still hang onto Imperial measurements for some stuff. Cheers, Ray

Thank you for the explaining the installation. Very informative and easy to understand. I'd been trying to find how to do this for a boat with shore power and your explanation is amazing thank you.

My under standing as to the delay in the transfer switch is so if your shore power is a generator, it gives the generator time to stabilize its output before sending power to the system. You can usually adjust or turn off the delay time with dip switch settings on the transfer switch.

Thanks Ray.

Nice sir, I think I need bigger than my 700-watt inverter to copy your move. Thanks again for reminding this old electronic technician that I still love playing with electronics. -Dave

I just installed this same inverter to replace my previous Motomaster 3000 watt modified sine wave inverter. My setup is for emergency home backup power with simple 14 AWG extensions to critical appliances, so no transfer switch or breaker panel. With my previous setup I needed an Edison plug to bond inverter neutral and ground to operate my furnace correctly. Same situation with the new pure sine wave inverter, but I elected to use the built-in terminal connections to do the bonding, so I just added a short jumper between N and E and closed the lid again. Now the entire inverter presents proper grounding to connected devices, including circuit testers like the one used in the video.

Great video! Thanks! I’m new to RVing, bought first camper in 2020 after returning to US from Canada where we rented a few times. I’ve been wanting to add an inverter, with this video I’m confident I can accomplish the task. One question, I have an onboard generator, do I need a different transfer switch, one with 3 separate inputs from shore, generator and inverter? I guess I do.

Very good but my solar power is completely separate from pole power and I installed separate outlets so I can be hooked to shore power and still use my solar power for whatever I want with the outlets that I installed for solar power works for me

Is your inverter ground(neutral) bonded to the case of the inverter(equipment grounding conductor)? Edit: Thanks for going into detail about the grounding :)

Hi thanks for the all the great videos. Just a question, did you upgrade the wires that go from the converter to the batteries, or did you leave the camper mfg.'s cables in tact after your installation of lithium batteries?

As Always a great and detailed video.. Just one question, everything else in the power system you have installed is protected by fuses in case of a short or failure. Should you not have a fuse in the 120V 30amp output from the inverter or does the inverter have a built in circuit breaker or fuse on the 120v inverter output.

@LoveYourRV

Yes. I took it apart and saw eight 40A blade fuses soldered to the circuit board for protection also there is microprocessor-control protection against low input voltage, high input voltage, short circuit, overload and over-temperature. Max output is 26 amps so as long a person uses a cable rated for at least that there shouldn't be a problem as anything above 26 amps for more than a brief instant will automatically shutdown the inverter output putting it into an overload state and cut off the AC output. I used a 30 amp continuous current rated RV cable as my main conductor. Cheers, Ray

Curious, how do you prevent AC operating inadvertently while on Inverter vs shore power? (Power outage or mistakenly forget to turn off). Is your shore power already combined & switched with Generator line in?

@LoveYourRV

Жыл бұрын

No, my generator is portable type not wired into the camper and only 2000W. I'm not sure what will happen haven't found out yet. :) Power outages are pretty rare and especially for both of us to be away from the camper at the same time plus forget to turn off the AC while gone. We also only ever need AC for about 2 months of the year. during the summer. When I head off grid, usually 8 months of the year, I routinely flip off the water heater, converter and AC breakers. But, I'll have to give it a test try and see what happens. My guesses are the inverter might have an overload shutdown or the 250A fuse might blow during the AC start up surge or the inverter will fire the AC up fine and it would run for a several hours until the battery bank ran down. Longer if the sun is out with solar recharging power from 940W of roof panels. So unless the power outage is extended things may work out OK. I could install a subpanel and move some breakers over to it so that the inverter could only ever power select circuits, Maybe a future project! :) Cheers, Ray

Ray, I'm curious what your voltage drop is at the inlet power of your inverter after turning the microwave on? When nuking lunch, I've triggered the low-voltage warning on my inverter a few times.

Warm is OK but hot means its creating too much resistance causing the voltage to drop.

Hi Ray, I am curious about the chassis grounding. From what I understand, most inverters are case grounded to the negative terminal of the battery.

In my fifth wheel, the DC battery negative is attached to the metal trailer chassis as some things use it as a DC negative conductor, I guess to save wire costs, also the AC ground bar is wired to the trailer metal chassis, and now the case of this inverter ground lug. Here is what this inverter manual says about the case ground terminal connection: "Prepare a 14 AWG copper wire with enough length to connect the inverter to a ground. Strip the insulation at both sides. Connect one end of the copper wire to the ground terminal (3) of the inverter, and the other end of the wire to the chassis or ground. NOTE: If connecting the inverter in a vehicle, connect the copper wire to the chassis of the vehicle. If connecting the inverter in a boat, connect the copper wire to the boat grounding system. If connecting the inverter in a fixed location, connect the copper wire to a ground rod (a metal rod pounded into the earth) or other proper service entrance ground."

Yes they do appear to be connected inside the inverter. So it appears redundant but maybe its a failsafe incase of something failing in a certain way inside the inverter.

Not sure, but when I had it apart in the first test video, I saw that the positive and negative inputs are spit into what looks like 4 separate sections on the main circuit board, each fused with two 40 amp fuses in parallel.

Hello Ray, thanks for your video. Question: I've got two inverters in my RV. The original is 2kW and came with the RV. I've installed a second 3kW inverter and it runs all the appliances. However, I have a 120V charger for my 2017 Chevy Volt. I can run it fine on the 2kW inverter, but the charger rejects the 3kW due to a 'bad ground'. Why would it work with one but not the other? I've connected the ground wire to the chassis as required. However, the AC ground (green) is not connected to anything except the proper terminal of the 30A plug I've connected to it. Basically, the original inverter should be fine, but the builder put 100A breakers on the DC inputs thereby limiting the effective power to about 1200W, which is not enough for a microwave etc. I got a decent price on a motomaster 3kW inverter and have installed it. I then plug my RV into it and shut off my converter. It seems work quite well. The other electrical equipment I've tried seems to work fine. Only the car charger rejects it. By the way, the original 2kW inverter is by Xantrex. Any good ideas would be appreciated. Henri (RVing with Henri)

It's likely because the Motomaster AC output isn't bonded neutral to ground. It's a floating neutral, so some things will reject it as miswired.

@@LoveYourRV Hello , again, Ray sorry to be a pest. However, in my situation above, if I plug in the RV to my wired 30A off the 3kW inverter wouldn't the ground wire from the 3k inverter be grounded to the RV frame via the RV AC distribution system? I can see your point if I just plugged in a load on the inverter's front panel and got a ground fault, but if it's connected to the RVs AC system shouldn't that ensure the AC ground wire is frame grounded? Or are these units wired so the neutral does not connect to ground so that the frame is not energized when stepping into the RV?

@LoveYourRV

Жыл бұрын

Yes, the ground from the inverter connects to the RV frame ground. But it isn't bonded to the neutral. In a normal shore power campground situation, the AC neutral and ground are bonded at the campground's main power panel, never inside the RV. So anything plugged into the camper sees that N-G bond. However, many inverters don't bond the neutral and ground but instead have a floating neutral, which works fine. I think most that have floating neutral are aimed at the mobile market where there aren't earth grounding rods installed, like cars, boats, RVs, and people just plugging stuff into them. I also think they are cheaper to manufacture. Some expensive inverters even have a way to choose floating or bonded neutral via a switch or jumper. Most things will work fine with the floating neutral setup, but some devices, like sophisticated surge protectors, will detect this and show a wiring error as open ground. See this page hughesautoformers.com/product/ground-neutral-bonded-plug/ Some devices sensitive to seeing a normal N-G bond will fail to start. An example is some home gas furnaces. See this page temperaturemaster.com/furnace-wont-run-on-generator/ My guess is your Volt charger is one of these devices sensing the non-bonded neutral and ground and not starting.

Found this on a GM-Volt forum www.gm-volt.com/threads/problem-with-off-grid-120-volt-charging.155625/page-2 but like I said I'm not sure if its wise to use a bonding plug on the Motomaster 3000W. Like I said haven't tried it yet since it seems to used a split voltage method of 60V on the hot and neutral to make the 120 VAC. So if the neutral gets shorted to ground it may damage the internals.
