MENU HEADING - METERS (4)
The current meters provided measure only the real, in phase component of the current. This is the portion
of the power that actually uses power from the battery. This allows better estimation of the DC power
drawn by the load or the battery charger. This may cause the reading to vary from other AC meters.
Inverter/charger
amps AC 00
Reads AC amperage. Positive amps indicate the inverter/charger is charging the batteries. Negative (-)
amps indicate the inverter is powering the AC loads and the batteries are being discharged.
Input
amps AC 00
Reads total AC current into the AC HOT IN input. The reading is positive (+) if the inverter is drawing
power from the utility grid to charge the battery or power AC loads and negative (-) if the inverter is selling
power into the utility grid (only available if SELL mode is enabled).
Load
amps AC 00
Reads the current that is going to the AC loads. This reading is always positive (+).
Battery actual
volts DC 12.6
Reads the battery voltage. Similar to the voltage reading of a standard DC voltmeter. The actual battery
voltage value is used for the LOW BATTERY CUT OUT, HIGH BATTERY CUT OUT, LOW BATTERY
TRANSFER, LOW BATTERY CUT IN and BATTERY SELL VOLTS settings.
Battery TempComp
volts DC 12.6
Note: The BTS must be installed for temperature compensation to be operational.
Reads the battery voltage after it has been adjusted based on the battery's temperature. This value is
used by the battery charger for its regulation settings. The value will decrease from the actual battery
voltage if the battery is cold and will increase if the battery is hot, which may give the appearance that the
batteries are being overcharged during winter and undercharged in the summertime. This improves the
performance of the batteries in cold weather and reduces gassing in hot weather. If you are using a
NiCad or other alkaline type battery, be sure to adjust the SET TEMP COMP menu item under the
BATTERY CHARGING (10) menu heading of the SETUP MENU to NiCad.
Inverter
volts AC 120
Reads the RMS value of the inverter's AC output voltage. When synchronized to an AC source, the
inverter AC output voltage would match the AC inputs value.
Grid (AC1)
volts AC 120
Reads the RMS value of the AC voltage at the inverter's AC HOT IN and AC NEUTRAL IN terminals with
the 'MAXIMUM AC AMPS IN' switch in AC1 position. This is usually the switch position for the utility grid.
Value will drift around before inverter has synchronized.
Grid (AC2)
volts AC 120
Reads the RMS value of the AC voltage at the inverter's AC HOT IN and AC NEUTRAL IN terminals with
the 'MAXIMUM AC AMPS IN' switch in AC2 position. This is usually the switch position for a back-up,
fuel-powered generator. Value will drift around before inverter has synchronized.
