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 batteries are fully charged, the display will change from Think’n to 100%

and begin to provide accurate SOC percentage values.

Info: Think’n can take up to several days depending on the charge

source and its ability to completely recharge the batteries (e.g., a

small PV array may not be large enough to replace all the AHrs in

a reasonable amount of time).

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

battery 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.

03 BM: Meters – This menu shows the battery bank’s DC voltage, DC

current, and AH information that has been provided by the battery meter.

The values for these meter displays are updated each second.

• DC Volts – Displays the real-time battery voltage from

07.00 to 70.00 volts (± 0.02 volts).

• DC Amps – Displays the real-time charge current (amps into the

battery) or discharge current (amps out of the battery). Charging is

shown as a positive (+) number and discharging is shown as a negative

(-) number. The range is from ±0.1 to 999 amps, with a 1.0% accuracy.

• AH I/O (Amp-Hours In/Out) – Displays the AHrs returned to/removed

from the battery. When the value is positive, it represents AHrs returned

to the battery during any subsequent charging. A negative value

represents AHrs removed from a full battery. The range is ±32,768 AH.

When using the charge efﬁ ciency’s Auto setting, the AH I/O value is

recalculated after the battery has been fully charged (i.e., 100% SOC)

and ≥0.5% of the battery capacity has been discharged. If the Sense

Module is disconnected from power, the AH I/O value resets to zero.

Info: The AH I/O display correlates with the battery’s Batt Amphr

setting to help determine the 02 BM: SOC display.

Info: AH I/O example: if you run a 10-amp load for three hours,

the display will show -30 AH. When you begin charging, the display

will count from -30 AH back toward 0 AH.

• rAH Out (Resettable AHrs Removed) – This meter displays the

total AHrs removed from the battery since it was last reset. This

display can be used as a battery load indicator to help identify and

monitor the battery load consumption. The range is 0 to 65,535.0

AHrs (0.1 amp-hour resolution).

To reset the AHrs value to zero, press and hold the rotary SELECT knob

for >5 seconds when this display is shown. After this display has been

reset, it will begin calculating and displaying new rAH Out values. This

display automatically resets to zero if the Sense Module is disconnected

from power.
