The Meter Interface (MI) accepts inputs from external AC and DC power metering sensors such as: AC and DC voltage and amps, AC kWatts, and DC battery capacity in amp hours and percent remaining. All with user definable high and low alarms.

• AC: 3 x AC voltage inputs (multi voltage), 2 x AC current inputs, calculates true RMS power.
• DC: 3 x DC voltage inputs (multi voltage), 2 x DC current inputs, calculates battery capacity as ampere hours and percentage charge remaining, resolution for current metering down to 0.1 A
