I will tell Michelle to give you all the 156 amp switches you want. No charge. She will get them from Walter, but I will show here where they are located.

Thank You Robin

I'll get them sent over to Russ .
Im thinking it worth a bunch of donuts for all the staff ! I can handle that as well .
Russ , I know yur a day ahead , but wake up !!

VT ;)
 EDIT ADD :
I have been in-touch with russ in Az land , I called & had a chat .
He was working with ryan on two WBjr's that failed  Said he couldn't post pictures etc for ryan .
I'm going to ask Walter to sell me two WBjrs for russ & let his AUZI dealer handle the problem .

Russ will send me his pictures & i'll resize them & post  them here & (russ where was your original post on the WBjr  ? )

I hear from Russ , he's doing Birthday stuff this week !! Sounds better than dun-dee ;)

Russ,

I bought some of these from the garage sale then Robin gave me some more. They are really rugged. They are wired 4 units in series but I have used some with wiring changed to parallel. Some are used on Caterpillar electric forklifts for emergency shutdown. None have failed. One of the forklifts had a stuck (welded) contactor which did a lot of damage when it raced out control. They can be remotely tripped but do not put non governed power to the trip coil. A 100 ms. Pulse at about 17 volts will trip them. The units are internally ganged so it's not possible to use them as independent switches. Midnite uses a similar trip coil on thr rapid shutdown systems so they have the exact details for tripping.

Same trip specs as the MNDC175RT  and MNDC250RT breakers. 

These units were custom built for Midnite so Carlingswich will not release any data on them but by downloading the E frame breaker catalog from Carlingswich you can deduce all the information from that catalog.

I have them on each of my battery banks just in case of a massive failure or short.

I have paypaled the cash for postage etc.
Really appreciate the help guys as I have had one chinese circuit breaker cook and do not want risk this again if the house is unattended especially in the summer months.
Only 24 volt systems, but once the input to the batteries gets to 50-60 amps plus things can get very warm.
I may have to turn up some step down cable lugs to fit into the classic so I can run heavier cable from the reg to the batteries as well. ;D

eight PM and now Im packing to move @ 05:00 loaded for my trip !
I saw the B17 working , BUT Michelle was off today & so I'm not going to push such a nice offer & ask/disturb Robin for a picture allowance . 07:40-09:20 @ the Midnite , postal till 16:00 & 4 trips , man !

Edit add : Im back in Kanada now & have my camera for post up the pictures , Huge breakers & weight .
Russ , USPS receipt  sent from e-mail

Sounds like a fun filled day Nigel.  How did the B17 look in operation?  As cool as the still photos so far released?

Yes I have slobbered over the b17 on the youtube clip :-[ :(
Be a long wait for me to procure one, sigh!
Even longer if they do not eventually make them in various voltages. :'(
Thanks again for all the effort Nigel!
Have to admit I got a bit of a scare when I saw that fried dc isolator switch!
I knew that they were not the best, but was all I had at the time.
Sure hope this cures the problems ;D

Well I saw it / looked at it doing it's thing BUT since I was on a mission I didn't really study it . I could of spent some serious time , But without approval , no movies or pictures ,and I was just passing by it on the way to Mr W office .
It was just before 9 Am or so as I passed it , cloudy gray day & light rain . It was doing something  cuz i saw one meter going blue /red . If I had know that it was setup & working when I first got there @ 07:30 , then I would of had a much closer look .

Edit Add: Ralph , I know yur still looking for an outback cover . I just haven't been in that area with the right folks , YET !
Canada & it's Customs is a huge pain , That is why I do all my stuff  myself .

Nigel, thanks for all the help with this. You are welcome to take pictures and video of the B17 or just about anything else we are working on. The only secret thing at the moment is the Little Willy. Magnum and OutBack are not going to like the Little Willey at all!

The B17 will have a 3 and 5 bay version. For those of you who have not seen the Alt-E video, go to our home page and look for the B17 article. You can click on something there that takes you to the videos.
The modules plug in with a blind mate connector. We are planning on 2000 watts per module, so at 48V, that is a bit over 40 amps. We do have 80 amp contacts on the connector, so maybe we can do a 24V unit, but it would be limited to the three bay version. We have an integrated 250 amp breaker. If you had two inverter modules and one controller module, you would be at 166 amps for the two inverter modules. You don't want to go much over that due to surge power. We could have a problem on the 48V five bay version depending on how many inverter modules are installed? We do use long trip curve breakers, but we are really pushing the limits here.
I do expect that there will be some good deals for beta testing B17's later this year to our forum gang, so hang in there. It really is a cool product. You normally don't sit around and stare at your inverter, but with the B17, you can't help but stare at it. It is just a very cool product.
We have another engineering tech starting Thursday to help out on the inverter projects. We are also toying with hiring another engineer to help Bob. The battery based inverter project is massive. There are four main battery based inverters, not just one. Our batteryless inverter projects are going well too.
Hope this helps,
Robin

Hi Robin,
can we get a B-17 specific thread started as Larry asked for, for the VOICE upgrade...?
 it would keep all the data /info easier to locate.

Been busy over winter, but I have the alloy for the switch mounting frames.
Just have to pull my finger out before the solar output start to peak again.
System has been making 10-12 kw per day on average and the rolls batteries are performing well for the "junkers" they were at purchase.
Switches/circuit breakers have remained a lot cooler over winter even thought the input has been similar.
