Rosie Testing in Texas!

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 !

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 !

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.
