Firstly, thank -you for the very prompt response to my question yesterday.
I got a very favorable quotation in the meantime, so much so that I am considering Quattro 8kVA building blocks instead of Quattro 5kVA models (budget-agreeable).
Anyway, doing my due diligence:
What is the difference between the two FW versions please?
And please can you tell if either or both FW versions expected to be available for the foreseeable future?
Thank you
