New Off Grid Inverter Charger

[CDN-VT]

The big B-17 will likely only support 48V. 24V will likely be in a smaller package around four years from today. There's enough of good D.C. TDC step down converters available that most systems will likely go to 48V anyway.

Robin  Posted that a 24Vdc is also in the works down the road.
No worries Vic ..
It's all for tomorrow

The attached preliminary brochure is all that exists at the moment.

24 v will be a problem with the limitation on module size twice the current means more transistors and twice the current.

Yeah, lots of "fine print" in the laws of physics when herding electrons.

Its all in good fun, tho.

Appreciate the pics and other tidbits of info. Looking sweet.

Robin, Tom, not sure I understand how half the voltage means twice the current... 

I understand that being the case  if the module output remains the same  but why does the output have to be the same per module? 

Why not half the module out put?

Well, good point on the half power modules. Not sure how it would pan out in hardware?

The half the voltage twice the current bit, as you apparently already know,  is Watts Law. Power equals current times volts for those who may not know.

Anyway, that is my arm chair input.

i think what is being asked is, why not have the modules output 1kw instead of 2kw for 24vdc input? of course if there's room for a few more fets then go to 1.2kw or whatever. this could expand to say 2 or 3 modules rather than 5 as it becomes more appealing to go to 48v at some point. being such a small version it could be a smaller plane designation such as the spitfire aka p51 or something similar.

[Westbranch]

Niel, you got the first part right and your idea of say 3 or 4 modules would overlap a single and double 2kw 48V modules.... makes sense to me...  .... Most makers have those types of overlaps in the 3 common voltage categories 12, 24 & 48

boB hard at work on the B17 program.

A Midnite Solar Lionel Train set under the tree for Christmas! I'd even settle for a Beta MS Lionel Train set!

So not one of the pink for girls special Lion Train sets?  Maybe the MS inverter has a small train guard figure with red flag pop out from a secret door and push the power button when an overload occurs

I am sure we will look at a 24V unit, but for the output power, it will be far more expensive than a 48V unit. Same cost, but half the power? We will be doing different battery based inverters though. Something more along the lines of a Magnum or OutBack FX. It won't be modular, but it can be powerful. For those of you that really want a 24V B17, I am sure we can cook something up. Even if it is just for forum guys and gals.
Give us a chance to get the 48V unit in production though.
Thanks,
Robin

+1....

Do you have a release date for the production units yet Robin?

[Robin]

No release date yet. We are still working on the design.

[russ_drinkwater]

Any idea of pricing at the moment?
