METER Menu

Pressing the METER button accesses the various meters that assist in
determining the status of the inverter/charger and the battery system.
Info: All displays revert back to the home screen (except for the
displays under the METER button) if no button has been pressed
for approximately fi ve minutes.

• METER: 01 INV/CHG Meter – This menu item displays the DC voltage
and current while either inverting or charging.
DC: V (Volts) & A (Amps): First value displays the voltage from the
batteries connected to the inverter. This reading's accuracy is ±1.5%
with a 0.1 VDC resolution. Second value displays (while inverting) a
negative number to show the battery current used by the inverter. If
charging, the DC: A (Amps) reading displays a positive number to show
the amount of current delivered to the batteries. The accuracy of this
display below 1 amp AC (~10 amps DC @ 12VDC) is not detected. When
the current into or out of the batteries is greater than 1 amp AC, the
display accuracy is ±20%.
VAC Out: Display provides the AC voltage measurement at the inverter's
output terminals. If inverting, this measures the inverter's output
voltage. When in Standby mode, this measures the AC voltage that is
passing through the inverter from the source (e.g., grid or generator).
Hz Out: Displays (while inverting) the output frequency of the inverter.
When in Standby mode, this meter displays the frequency of the
incoming AC source (i.e., grid or generator) that is passing through the
inverter to the inverter's output terminals. Frequency in Hertz (Hz).
Load Amps: Displays the AC amps as measured on the inverter's AC
output terminals. The reading is positive (+) if power is being pulled
from the inverter to run an AC load—either using the batteries in
Inverter mode, or from the AC input source in Standby mode. The
reading is negative (–) to indicate power is being returned to the inverter
through the AC output terminals—possible in an AC coupled installation.
(MS-PAE, MS-PE and MSH Series models only)
Input Amp: Displays the total AC amps being used by the inverter
for charging and for powering any connected load at the output of the
inverter. This reading is always displayed as a positive (+) number. (MS-
PAE, MS-PE and MSH Series models only)
Example: If the charger is using 20A from the AC source and the load
connected to the inverter output is using 10A, the combined load on
the incoming AC source is 30A. So, 30A is displayed as the input amps.
I/C Amps: Displays the inverter or charger amps. A negative (–) amps
reading indicates the inverter is powering the inverter loads and the
batteries are discharging (inverter amps). A positive (+) amps reading
15
