I'm looking for a COTS or MOTS option here. I can do some soldering if need be.
I am looking for a DC input charge control board for some #LiFePO4 batteries. Ideally 12, 24, or 48 volts, and at least 100 Watts. 2 stage constant current/constant voltage, of course.
I have searched high and low and everything available is an AC/DC converter. I specifically want a DC input.
Anyone know if #solar mttp chargers are acceptable to use with DC voltage generators?
I prefer the bar chart view, it seems even more precarious to me.
I've done nearly everything I can personally do. #SolarPanels, 7 years ago. #ElectricVehicle, 6 years ago. Switch to #HeatPump, 5 years ago. Testified for bus lanes and better #MBTA service. Other life changes too.
I was even the #solar coach for for my community years ago, we got over 100 homes solarized.

Interesting moves in the #ElectricVehicle changing space lately (in the US and in Canada).
It sure would have been nice for the US to mandate some open #EV charging standard years ago, but it seems that everyone is coalescing around #Tesla's so-called NCAS "standard".
Right now, it seems to me that NCAS is not actually a standard, but rather, an open specification.
Hopefully, this gets on an independent standards track.
This is a story about #manufacturing competitiveness in the US.
About the Manufacturing USA initiative.
About the MxD innovation center in #Chicago (formerly known as DMDII).
And, about my frustrations that have festered for some time.
Out of respect for some of the people that I know personally that were employed there (who I will not name), this is a story that I had kept to myself for some time.
But now it is time to share, for a variety of reasons.
It is important to note that #China has long and substantially subsidized their #manufacturing industry. China has also exercised a considerable degree of central state planning and control... some of which, like #battery and #ElectricVehicle production and its associated supply chain development, are paying dividends today.
The US is not really structured for that, well, politically.
So, the institutes embrace a common approach - the public-private partnership.
This is great and all, but we really need to build ways for people to get to Downtown #Detroit without driving and for people to get around Detroit without owning a car…
I am fine with #ElectricVehicle charging infrastructure for street parking, but not city-owned surface lots.
Surface lots should be seen as temporary, never permanent.
About 80 percent of new cars sold in Norway are battery-powered. As a result, the air is cleaner, the streets are quieter and the grid hasn’t collapsed.
