5.1 METER Menu Items and Settings
Press the
METER
pushbutton on the ME-RC to access different meters, which
help determine the status of the inverter/charger and battery system.
Figure 5-1, Accessing the METER Menu Items
01 INV/CHG Meter
- This menu provides the DC voltage and current of the
inverter/charger only while either inverting or charging.
The DC: V (Volts) display provides the voltage from the batteries connected to
the inverter. The DC: V accuracy is ±1.5% with a 0.1 VDC resolution.
While inverting, the DC: A (Amps) display shows the battery current used by
the inverter. If you are charging, the DC A (amps) display shows 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%.
02 BM: SOC
- This display is the best way to monitor the actual state of the
battery. The “read only” display shows the State Of Charge (SOC) for the
connected battery bank. The SOC represents the condition of the battery
as a percentage of the available capacity left in the battery. Range is 0% to
100%, where 100% represents a fully charged battery and 0% means the
battery is completely discharged.
When the Sense Module is
fi
rst connected, the batteries will need to be fully
charged (i.e. SOC = 100%) at least once to establish a SOC reference point.
While this reference point is being calculated, the display will show “Think’n”,
to indicate that the SOC reference point is being calculated. After the batter-
ies are fully charged, the display will change from “Think’n” to “100%” and
begin to provide accurate SOC percentage values.
If the Sense Module is disconnected from power, this display resets to “Think’n”
and the batteries will require another full charge before this display begins
providing SOC percentage information.
Info:
Try to limit battery discharging to 50% of capacity (keep bat-
tery above 50% SOC). If batteries are allowed to be continually
discharged below 50% SOC, their effective service life will be con-
siderably shorter. This 50% rule has been determined to be the best
compromise between available energy and the maximum number of
discharge cycles a battery can provide.
