NaS batteries

NaS batteries

(OP)
Hello everybody,
I've visited this forum several time before, but this is my first post, so please forgive me if I've not found the right section of the forum.
I've been involved in an energy storage project; I am searching for information on the NAS batteries and I found some conflicting information on the web:
for example in various articles and sites (such as the manufacturer's one)  an ac-ac efficiency of 75% is reported, while a Sandia report and some NYPA documents show values ​​slightly above 60%. As far as I know some of these batteries have been installed in the US and in UAE, is theresomeone in the forum that has had to deal with this kind of projects? It would be very helpful for me to be able to have his opinion is about this.

Many thanks in advance,
best regards
