ISLANDS and AREAS of LIGHT – Infrastructure Development
Electricity: The 'return' of the DC (direct Current) – A Brief Overview
IEC standards activities on LVDC for electricity: 
"LVDC is still considered as a highly disruptive technology • LVDC needs to be safe and reliable, at least to the same extent as AC systems • There is still a lack of standards, with no consensus on DC voltages, earthing for islanded microgrid arrangements, protection solutions, plugs, sockets, etc."

Challenging the status quo. LVDC: the better way

"A disruptive technology is one that displaces an established technology and shakes up the industry or a ground-breaking product that creates a completely new industry."
AND YES!!  The old and disgusting established AC system of 50/60Hz MUST BE DISRUPTED!!
Solutions are already in place for small off-grid ELVDC nano-grids.
It seems India is in a top position of day by day development.
Material is put together in our blog. Search the links of interest!
Yes, there is a ELVDC standard in place for India!
It is NOT a joke! It may be used for islanded off-grid communities from anywhere, not only India.
Here it is!

You have either to 'awake' or to 'retire'...
