The older (pre-decessor or just re-packaged?) Link 10 meter from Xantrex was also limited to 35V (it is the 7800-series linear voltage regulator max input) so a 1:10 pre-scaler could be used to measure higher voltage, while powering the unit from an isolated power supply between 12-35V although if it is just 48V as in your case, the prescaler is needed but the power supply can simply be a zener diode, dropping the 48V (max charge voltage for example 60V so you would need a 25V or next higher zener)
If I am not mistaken, the Link 10 had a software feature to shift the decimal dot a place so you could take the 10:1 pre-scaler into account in Voltage and energy measurements. Not sure if this unit has that same feature - Lee might know as he has made a companion board for the Link 10.

Marco Gaxiola via EV Sent: Fri 7/24/2015 11:08 AM To: 'Electric Vehicle Discussion List' Subject: [EVDL] 48V Energy Meter (Lead-Acid)... I'm looking for an energy meter for a lead-acid 48V (Nominal) bank. A friend recommended me this one from Xantrex: http://www.xantrex.com/power-products/power-accessories/linkpro-battery-monitor.aspx that looks great and ideal for my Project. But unfortunately maximum reading voltage is up to 35Vdc. (although using a pre-scaler in the input voltage and a 48V to 12V DC-DC power supply; the firmware parameters in the programming options of the device, according to the datasheet; are only up to 35Volts range) if someone does know of a similar product solution that could be recommended, please advice. (Application: It's intended to be used on an Electric Polaris Vehicle. I'm upgrading the battery pack, extra charger and adding some solar panels in order to improve range, charge time and ability to slowly self-recharge while in the sun. To be used on a Ranch.) Ing.
