9. External Shunt
When two inverter/chargers are utilized in a system, an additional RC7 can
be used as a battery "fuel gauge." This requires an external shunt. Refer to the
inverter/charger's Operator's manual for instructions on installing an external
shunt. The External Shunt menu selects the fuelgauge unit. The default is None.
External Shunt:
None
10. Fuelgauge Cutout
The Fuelgauge Cutout menu sets the battery voltage zero percent state of
charge (0% SOC) with no load. This is the point at which the battery has zero
reserve amp-hours remaining. The Fuelgauge meter uses this number to
determine the 0% battery state-of-charge voltage. The default is 9.5 VDC.
