1. Isthebatteryproperlyconnected?
a. Checkthewiringbetweenthebattery,shunts,andtherectifiers.
b. Checkthattheshuntsareproperlyconnectedandsized.
2. Istheconfigurationcorrect?
a. GotoSystems > DC System > System Functions > Battery Runtime & Health.Confirm
thatBattery Estimation isEnabled,theLoad Model iscorrectforyoursystem,andthe
Battery LVD valueiscorrect.
b. GotoSystems > DC Systems > Inventory > Battery.SelecttheGO TO buttonand
confirmthattheCapacity Rating andthePeukert Exponent arecorrect.
c. GotoSystems > DC System > System Functions > Battery Test.Forgreatestaccuracy,
checkthattheBattery Test Timeout,whichistheamountoftimethebatteryteststays
