I really like the idea that someone could throw something together in a couple of weeks. Wish it were that easy, but we have to deal in reality here.
We were starting and running an air compressor last week with half of a single B17 inverter module. We need to dial in the over current protection of the gate drivers. There are 24 gate drivers on each 3000 watt 120/240VAC inverter module. Mike and PAtrick will be creating the test plan for that and then dialing them in. That is not a hold up though. Bob is now working on paralleling code. That will allow us to do air flow testing in the main frame. Then Bob will finish making the charger section work automatically. There are others involved in this project too besides the inverter engineers and technicians, Mike and Patrick. Mario needs to spend some time on the MPPT power module. He has been up to his eyeballs on the Hawke's Bay and Barcelona. Mario has but one technician, Lee. Mario and Lee are juggling the B17MPPT, Hawke's Bay and Barcelona. His second technician has gone home for hospice care due to pancreatic cancer that 3 months ago he did not have? We will miss PeterB. Peter did redesign many of the B17 and Barcelona boards before leaving us. There are other engineers too working on the controller board for the B17. We call it Justin's board. Justin is the engineer. Justin has been heavily involved in making our products upgradeable in the field. We have MAtt who is doing our phone apps to upgrade the code in the field as well as making it useable for data as well. We have Darren (formerly from Trace) working on boot loaders, and arc fault and MNGP2 menus. We have James working on boot loaders for charge controllers and the MNGP2 hardware. James will soon start a touch screen version of the MNGP2. Don't expect that for a while though. We have Sami (formerly from Trace and OutBack) who is working on B17 circuit board designs. Seems like we are always redesigning circuit boards for every project? We have Jeremy backing us up in SMT and will soon start the "Lunch Time Project". We have 30 SMT machines now, but Jeremy only works on new projects. We have a team of SMT operators for production boards. We have Scott (formerly from Trace and OutBack working on the aux power supply and control board for the B17 inverter module when he isn't designing our own Lithium hot swappable battery system. We have Jim who is writing code that interfaces Canbus to the B17 and Rosie and will soon begin the Classic to ComBox interface. We have Monroe who is doing the web server inside the ComBox. We have BobQ and Doug who along with me do all the mechanical designs on all projects. We have Gordon who we use to build prototypes. We think Gordon is actually from Mars. We have Linnea who is our very experienced board assembly person dedicated to engineering projects. We have Tony from Trace and Magnum who is attempting to coordinate all of the engineering projects. There are more than you are aware of. Andy gets his hands involved in just about every project including the B17 even though the Rosie is his baby. The Rosie is really coming along nicely. We have Dan who is getting our environmental chamber up and running as well as writing the production app for all the new projects. Dan also works with the NRTL agencies. We have Dawn who is the engineering buyer. We keep her pretty busy getting parts for everything. She also keeps the squirrels outside her office supplied with peanuts. We have PeterH who is designing a bench power supply. Hmmmmmm, it would appear that PeterH is the only person in engineering not working on the B17 in one form or another. We have been granted 8 patents on the B17. I think that means that maybe we aren't just reinventing the wheel. This stuff just isn't easy. I have worked with some great engineering teams over the years at Trace, Xantrex, OutBack and Magnum. I can truthfully say the MidNite team is far and away the best I have ever worked with. Nobody is taking any longer than they have to. Like I said, This just isn't easy!

Where can I get the b-17 specs.
i.e. Input and battery voltages available?

I'm looking at replacing 6+ Classic 150s, and two 12K inverters...
Not that I need too, but because would be cool to have the B-17 system.
** But a technical improvement reason would be good too. :)

If possible 96 volt battery bank and higher input voltages such as 300 plus would be sweet.

Thanks for the Link Vic.
I assume once they get closer to release there will be more detail.

Cheers

Rest in Peace Peter.  Thanks for all the efforts to make things better for us all.  I look forward to using the thinks you helped make better!
