Came upon this thread looking for reliability reviews of the NPFC100 Narada Batteries.
I have purchased 2. The Narada software was given to me by the vendor and a cable also provided. The cable is an RS232 DB9 TYPE PLUS a Converter to Rs485/422. only 2 wires on the rs 485 connector are attached as given in the manual. This arrangement allows monitoring on a laptop but will obviously not integrate into older inverter systems like outback which I run.
