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

Just bumping this thread to see if any release date (or pricing) is imminent for the MNB17?

boB said Mid Summer, but didnt specify what summer :)

I think we are looking more like Q1 of 21 for out of house alpha testing but we should no more in the next 2-3 months


This thread was started two years ago and this is the best info thus far??? What is going on?

What is going on is that we are spouting out things before we should be.

Aside from saying things that we should not be saying, I suppose we are mentioning progress.

If you really want to see what is happening, if you are in the area, please come by and we'll try to show you why this stuff is not easy.

Thank you  littleharbor2  !

I really wish I could stop by. That would be a real treat. Unfortunately I live in Mexico so it's a bit of a commute.

Little harbor #2 is the campsite I camped at perpetually over about 15 years so I created my email address with it. Decided it works as my name on these solar forums.

Thanks Mike !   I knew a few people that moved to Mexico.  And we have several here at MidNite that cam from Mexico.  Great worker and people !

Update from August 2022
Bob and Mike continue their quest to finish the inverter module. It is truly awesome. I had to ask Bob to stop for a bit to add Lithium menus on the Classic. Some people wanted that and it shouldn't take too long, but Bob wants to do a bit more.
So I moved Mike, the tech to the Barcelona department since we are actually shipping some of those and the Hawke's Bay now. We just finished a bunch of testing on the Rosie with ETL last week. Not totally done yet, but we did the hard tests. After ETL left we decided to see just what the Rosie was good for. We had to trick the over current protection in order to surge it beyond the limits designed in. We got a real honest to goodness 20,000 watts out of one Rosie for a short burst. Then at 22,000 watts we broke some fets. This thing is really powerful! I was surprised when we did a 14,000 watt surge and saw it was still regulating at 241VAC. Typically inverters will droop at that kind of overload. The Rosie didn't care. The ETL testing showed we have a 7000 watt inverter with a 120 amp charger. Both of those figures will increase in the future. I am guessing at least 7500 watts and maybe 8000? The charger may be able to go to 150 amps. We are just in our infancy with the Rosie. We can already sell as many as we are able to build just into the RV industry. We don't want to dedicate all of our production to the RV industry though as people are going to want the Barcelona and Hawke's Bay to go with their Rosie. We have $millions of dollars of parts in house now for these new charge controllers, so it would be a real shame to dedicate all production to the RV industry. We start production in October on the Rosie.
We are also working on an inverter called the Little Rosie. That one is specifically for the RV industry. It should be high volume.

So back to the B17, I expect we will ship some beta units this year. We still need Justin's board (communications) before we can ship. The inverter is mostly done now. Bob needs to finish the charging part of it. Mario needs to get his MPPT modules done too. Mario has been up to his eyeballs getting the Hawke's Bay and Barcelona into production. The B17 MPPT is basically a Barcelona, so we do not expect a lot of problems.

So, by the end of this year we should see units going out for beta testing. Production will begin as soon as bugs are mostly worked out. Code can be updated in the field so not all features need to be finished. One feature we do need to finish is to be able to update code in the field. That isn't done yet.

We are showing the B17 at SPI in Anaheim this September. We have a great live demo of its capabilities as it exists today. Please stop by if you can. We do have some guest passes available too, so feel free to ask. We will pass them out until they are gone.

WOW !!  Great progress report on many products, Robin.

Greaat work, as well,  getting parts into inventory.

Am anxious to get hands-on the 600 V Charge Controllers, and a Rosie, when it is time.

Edit to add:  Thanks to ALL of the MidNite folks for doing all of that hard work!  Sure sounds like it is all coming together.

Thank you very much for the update,  and have a great SPI,  that should be a lot of fun-work.
Take care, Vic

Yes very nice news. Though as beautiful as these products are I have to admit, dead of winter -40 below zero with -60 wind chill and 2 hrs to get into town if your vehicles can start or get out of the snow bank I will have to stick with the Classics for my system. One unit operating everything in those conditions goes down can mean death out here, versus having multiple Classics so if one goes down you can limp along till something comes in the mail that runs only 3 days a week here at most.
Beautiful to see American ingenuity progressing in the solar world form here.
