Robin, about that spaceship........

I got the deluxe kit, it had a solar cell and a meter.

Midnite B17-10. 50kW Cont. 150kW Surge... Me/Myself/And/I

You forgot BobQ and Sami.
Linnea is our engineering assembler.
Ryan and Roy serve a very important function keeping the engineers going down the right path also.
We have a huge engineering staff compared to our competition. They can much better afford engineers, but they just don't do it?

I have always wanted to design and build stuff. I remember in the 7th grade searching for a couple of 55 gallon drums so I could build a submarine. The rocket ship is no different.

Has the B17 reached production or stalled in development?

No development stalled.  Well under way and busy every day.

It is just taking much longer than expected or wanted !

Any update on the B17 Bob?

No, sorry.  Still working on it.   A  LOT of us are working on it !

Any chance for a six month checkup?  How is Rosie and the rest doing?

The one thing is the one thing

FNG

Still a good bit to go,
The B17 is making ac but is not charing the batteries yet. boB is working on that still, I suspect 2-3 months for off site alpha testing.
Rosie, This was given to Andy and he is working on it daily but it is probably a bit further out say 3-5 months for off site alpha testing.
Barcelona and Hawkes bay are both under the guidance of Mario and I would say are 2-3 months from off site alpha testing
The Comm Box, This one I am not sure I am guessing it is about inline with the Rosie
MNGP2 is taking shape, we (All of us) are working on menus and layout now

Robin

We just hired three more engineering technicians and two engineers.
The second go around of Rosie boards are now finished and ready to order. The Rosie has undergone tons of changes so we have high expectations for it. Beta units of Hawke's Bay are starting to be assembled. There were numerous changes to the unit and new boards are on order. One thing we discovered was the sealed Hawke's Bay was only outputting 70 amps at expected temperatures. We wanted 80. Some changes are in process that should result in 75 amps. Because of this, we have elected to create a vented version. IT will be a bit more expensive as it has more expensive parts, but it should come in at 100 amps. So........what does that mean for the Barcelona? The Barcelona is actually two Hawke's Bays in one enclosure. I do not believe we will see 200 amps though. Might get 180? These things are very powerful!
The B17 is coming along fine. So is the B17-B We just ordered 13,000 battery cells for engineering test samples. Each 48V 1200 watt hour plug in module uses 96 cells. There are as many as 8 modules per unit. That makes the cell quantities add up very fast.
Production areas are being set up in 4 new buildings. They won't be enough, but you gotta start somewhere. Sunspec receivers and transmitters are now ready to go to NRTL testing. We are waiting for quotes.
Don't know if a Little Rosie would be a viable product based on price, but if it turns out to be, there will be a 3000 watt inverter also.
There is another project we have discussed at length. The "Lunch Time Project" More on that later as we get resources allocated. That is why we call it the Lunch Time project. It only gets worked on when we go out for lunch. We have tons of napkins with sketches and schematics of that project.
Things are very busy here for sure.

Robin,

Nice update.  Are you using 18650s or another battery?

Can't wait for Barcelona and Rosie!
Brian

Robin

The 18650 is too small. I do not recall the size we are using, but it is 3.8 milliamp hours per cell.
