I have a tracking number and Rosie is set to be delivered today!
A little background. Robin had a thread here on the forum which was the contest to name their new inverter. The B-17 was already named. Their smaller self contained inverter was planed to be either 2000 watts in 12 volts or 4000 watts in 24 or 48 volts. Well we all knew from the start it wasn't going to be ONLY 4000 watts. Heck its Midnite. But the new smaller plucky inverter needed a name.
Other offered very good names and the contest continued. I even tossed in a few names that did not make the cut. Then I was talking to a good friend about a physics class back in the day and I remembered some of my professors and the staff which guided us along. One of those people was Stella, she really was one of the Rosie the riveters back in the day, except she was a welder back in WWII. I thought, hey, how about one for the ladies and I offered "Rosie" as the name. Well I got calls from several on the ladies who work at Midnite thanking me for including them. The name stuck.
Now today, I am about to receive my Rosie to test here in Texas. I have a lot of stuff to play with in the barn including a five HP air compressor, and my welder. I am told Rosie is ready. I have a good friend who is an electrician and will make sure I am safe and by the book. But I plan to test Rosie to her limits. Its what we do. Mine will be named Stella.
The anticipation is growing, but I can wait. This weekend will be filled with moving equipment and the first few tests. Then long term testing begins.
You are all welcome to follow the journey. It is going to be electrifying.
Rosie is in the house!!
Rosie has made it to the farm and I am getting every thing ready to be able to install her today if everything goes to plan. Fingers crossed.
I am excited for you dude. Pics will help calm your followers tho. I am also hoping to receive a beta Rosie. Got my Mail and.few days ago. Any word on the idle current draw.

Okay, Rosie is on the wall and I'll take a picture in just a few. I am trying to get everything done but with this weather, It is a real struggle. But I do owe you guys a picture! STBY.

Nice
Rosie (Stella) is alive and updated!
Now Barcelona, Hawk's Bay, Rosie and both MNGPs are updated and talking over the Canbus.
I really like the current updates as they are maturing very well.
The system screen tells you about the total system and you know at a glance the status of the entire system.
If you look at the MPPTs section, it combines the outputs from all charge controllers and you know what you are "making."
Looking at Rosie's section tells you what you need to know about AC generation and Rosie's output in amps and watts.
I will let Rosie run for a few days and then test her a bit. The Air Compressor is still waiting to give Rosie a run for her money!
All in all, Very nice updates and I really like Rosie, she has been worth the wait!
HF,
I have a couple of questions. are you able to monitor rosie and the controller remotely through mymidnite or any other available software.
The second question is about the dongle on the DIY inverter. Are you able to monitor the activity and status of the DIY inverter remotely. I have a 3024 and have one on order hoping that I could monitor its activity from work.
Can you determine the real world ideal draw of the Rosie.
Thanks much
Damani
HF,
I am not sure if you can answer this question...if one had a classic installed with a rosie and a mngp2 will the mngp2 also report on the activity of the classic.
Damani
question for midnite,
Is the rosie innards conformally coated and if not what is the expected peformance over time in an environment near to the sea not necessarily directly in a marine environment.

Damani,
Midnite is working on a new path for remote monitoring of the new devices. I expect that testing to happen sooner than later. I have my fingers crossed it will be very soon.
As for the DIY and its dongle, Yes I can monitor the DIY from anywhere I have internet access. I used my android tablet to setup the DIY using the free downloadable app. It lets me see a good amount of information. I found it way easier to use an android tablet than my Iphone. The Iphone app was a real pain.
I believe the Classic and the new stuff are not yet talking to each other but I bet they will. The engineers who are programming the new stuff are making very good progress.
As for the idle draw, I would say it is low. I have not put an amp meter to it, but using the system with the Rosie loads off, Rosie was only pulling around a tenth of an amp, so I would put that around 5 watts. Plus or Minus, but that is just better than a WAG. I would bet Midnite will have the real answer soon enough.
As for the coatings, I'll let the engineers answer that one as well.
"Well, I could not wait.
I hooked up the 5HP Air Compressor up to Rosie. With the tank at 135 PSI and the motor cold (5C in the barn), Rosie did start it up but after several seconds, Rosie tripped. Three minutes later I had the tank bleed down to 130 PSI and we got the same results. So after another three minutes, I bleed the tank to 120 PSI and she started it up and ran until the tank was topped off (around 30 seconds). The conditions were not ideal, but she did it. We used 50 feet of 10 gauge wire from Rosie to the compressor. The MNGP said Rosie was making just under 6000 watts continuous, NO fans came on. We will retest after Rosie is mounted by the main breaker box. That is the biggest load I have in the barn, it is good to know she can do it!"
We will continue testing and updating as Midnite send out new software. I am going to add several resistive heaters today and she how she does with them.
Many thanks HF. I am wondering how Rosie would cope with a stick welder. Did you setup any meters to test the in rush current while trying to start the compressor.
Damani
Damani,
I have a MIG welder which will be run using Rosie as soon as I can get things setup (*I do not have a spare 240 outlet here at the farm right now). I suspect Rosie will run my welder very well. For reference, I have a millermatic 180.
Inrush was not taken with an amp meter (midnite has a video or two showing inrush earlier), but the MNGP showed a sustained 114 amps while running. I missed the inrush if it showed up on the MNGP. The voltage was very solid during the tests. In short, I was impressed with Rosie's performance.
HF,
I was checking the post and didnt see any reference to your system the rosie has been installed with. Could you advise on the main system components your Rosie is working with.
Damani
You bet,
I have a Hawk's Bay, a Barcelona, a DIY 5048 and Rosie. I am using lithium (600 AH) for my batteries and I have around 6kW of solar panels powering my aquaponic system.
I have a backup lead-acid battery which is charged by a Midnite windmill.
I plan to use Rosie for the entire barn after I learn what I can do with her.
Does that help?
HF,
Yes it does. Your lithium are LifePo4 and are they built by yourself with cells or a finished product like the rack mounted battery systems. 30kwh bank is a good size as well.
Damani
Damani,
I use both, but the system with Rosie is rack mount LiFePo4 batteries.
Well we ran several thousand watts for hours a day or two ago. Rosie did not care. Temps were very good, and no hot spots found.
I think we will up the game next week. I think I'm going to need a bigger load.....
I wonder how Rosie would handle a 7kW load for hours on end? Like for charging my EV. That's assuming I have enough battery/solar to keep up.
Mike
Mike,
That is on the list of tests. I'll let you know.

I think the Charger portion is good for some 5+ kW but not quite 7.
Like, 120 amps or so
boB,
I thought he was asking how using the 240VAC output from Rosie at 7000watts to charge an EV (level 2) would work out. That is the test I am going to get ready to do.

Oh ! OK.
That might be more.
Lettuce know hot it goes !
boB
It should be a cool cucumber.
The new software seems to be maturing well. The SOC for the battery pack seems right on.
I have increased the loads on Rosie, but I have not yet pulled the full 7000 watts for more that a few minutes. I have pulled over 4000 watts for a long time and found no hot spots. I am adding additional outlets to see if I can get to the full 7000 watts next week. Also, I now have the material to move Rosie to the area where the E panel for the entire barn is located and plan to run on Rosie power alone if possible. Testing continues.
I do know the fans do run, but only because I reboot after each software update. So far, Rosie has exceeded my expectations. She is a great tribute to the ladies of the greatest generation.
Rosie keeps on running well above my expectations. I now have the parts to add a 30 foot 240 outlet to my E-panel for Rosie to power my Welder. I am going to guess the welder will be no issue. It is a Millermatic 180 in 240 VAC. I'll let you all know how she does after this next trip. Here is to welding up my next array with solar power from Rosie!
Awesome Brian !
Really glad it is working good for you !
What do you think about the performance to weight ratio ?
MY new marketing term !
boB
Funny you should say that as I understand the RV market is really interested in Rosie. Pound for Pound, Rosie is one of the best inverters I have used.
Think about it, at 7000 watts, Rosie has more available watts than a home power panel's inverter. You get to choose the battery size and at 7000 watts, run what you would like for as long as you would like. It is all up to you.
Also, I think I remember you or Robin saying Rosie might get upgraded to something more than 7000 watts. Is that still in the cards?
Well Yesterday I aded a 40 foot lead with a 240V outlet to Rosie's E-panel. I used it to run my welder out in the yard. I had no issues and Rosie handled it with ease. I was pulling just under 3000 watts just from the welder. All other loads were on normally. Each weld burned between five and 10 seconds. I did add an extra light or two and a fan to the mix. Still no issues.
Also, I have a neighbor with an EV, I have asked if they want to come over and charge for a while to hold Rosie around 6500 watts charging. The rest will be my normal loads. More to follow.
Finally, as it warms up here in Texas, It will be interesting to see if I get the fans going.

I, too, was wondering if the fans worked. It required my microwave to run for about ten minutes before the Rosie's fans kicked into slow speed. I wonder if how the fans will react to the summer temps since the inverter is living in the garage. While not Texas, Ohio in the summer can get quite toasty.

Eventually. Slight changes to hardware and software would do it.
Normally, people don't run these things at full power very often.
Also, we have to finish all the other features first. Then we can think about more power.
BTW, Speaking of features, you can now stack Rosies !
boB
All good, but here at the cabin WHEN I finally get an EV, I will charge it from Rosie. Now I just need that neighbor to stop by for some free testing!
Well we had 120 MPH winds during a storm a week or so ago. Rosie was a life saving device. It took several days to restore gird power to our area, but I had Rosie. Oh and the solar panels on my tracker did great a well. It was over built for a reason.
Score another for Rosie.
Well today it was over 100 degrees F in the barn. We loaded Rosie up with around 2400W of load for over four hours (I did not have anything else to add to the load). I did hear the fans on low at times, but the temps where almost the same. Rosie seems right at home in the heat. later this summer, I'll add a few more loads and see what I get.
Fantastic, Brian !
Especially where your power was out !
boB
Well I updated to the latest Beta for Rosie. I am Burning a few more kWh just to see the data which is now being collected and shared.
A request would be to have all of my data logs be available on one page just like the status page.
It might look like :
HB kWh produced today, and total. Converted to mWh as needed.
Barcelona kWh produced Today, and total. Converted to mWh as needed.
Rosie kWh produced today, and total. Converted to mWh as needed.
This way I could see on one screen the total production from each charge controller and inverter in the system.
I could then foresee a contest to see who is generating more RE using these devices.
I must say, I love to see the data.
Late last week, I needed to work on what I call Tilapitopia. It is our Tilapia aquaponics system in our barn. We over winter Tilapia and brood more each summer for the following year.
To clean out the tanks, I use a pressure washer and vacuum. I also use pumps, lights and fans. All of this was powered by Rosie. Turning on a two HP vacuum while an electric pressure washer is running was no issue for Rosie. In fact, there were several times when both the vacuum and pressure washer started up at the same time. Everything ran just fine. While I don't think I hit any limits, it was reassuring to see Rosie handle the surges flawlessly. More testing to follow.
Well it has been just under one year and all is well. Rosie has been doing all kinds of work and has produced just over 3mWh in 11 months. The new location is ready and I am hopeful I can move Rosie and Barcelona to the wall by the door and make them permeant. When that happens, I should be able to run the entire barn including the air compressor. I know I have been working for a while on the location move, but there have been a few family events which took priority. Needless to say, family before fun. One other note, I have loaded every Beta software version so far. I have never had Rosie fail after a successful upload. I have had one or two issues uploading, but they have always been correctable. Rosie is a beast so far! I wish I had two! Rosie just runs and runs.
We had good sun Yesterday and I decided to run Rosie a bit harder. In the end, during the sunny part of the day we made 35.3kWh of 120/240. I used it for all kinds of things. I ran several heaters in Tilopitopia, and one in the barn. I ran pumps, and lights. In all, Rosie really did not care. Today I ran one leg to 3700 watts and the other was only pulling 250 watts. I did get the overload light and warning, but everything ran for over ten minutes before I reduced the load back to just within limits. I then ran Rosie at that level for the rest of the sunny part of the day. In all, the only other test I can run is charging an EV. To date, I have not yet been willing to pull the trigger. Some are tempting, and others seem to spoil the mood. I really need a new truck, but none of the offerings have made me scratch that itch. I guess it is time to go for a few test drives.
Read over where Barcelona testing in Montana is at you will see a blood bath happening with Rosie and Barcelona. They can take the heat, and take a load, but can't take the cold.
I'll take a look, mine are in an unconditioned barn in east Texas where it is getting rather cold, but not Montana cold! So far, I have had no issues with the cold here through two winters, but again, not Montana winters here.
