Battery Management Module
The BMMD Status Screen indicates the Battery Voltage (VDC), the
combined Battery Current, and the approximate battery State of Charge (%)
for lead-acid batteries or a bar graph showing relative magnitude of the total
battery current for lithium-ion batteries.
The SOC% is estimated by counting the ampere-hours (Ah) flowing into and
out of the battery while knowing the nominal rated capacity of the battery.
The system resets the SOC to 100% whenever it detects that the battery is
at the rated Float Voltage with minimal charge current for at least 24 hr.
Other information will be shown depending on the operating state of the unit:
•
Battery current will be zero when not charging, + while charging
and − while discharging
•
LOW indicates a battery is disconnected or over discharged
•
A battery graphic marked with X indicates the battery is
disconnected
Press Enter to move to the BMM Settings.
BMM Settings (All Battery Types)
The module comes with factory default settings that should be reconfigured
to match the actual battery used in the system.
WARNING
Always consult battery manufacturer’s specifications when
selecting battery type. Incorrect battery type setting may damage
the battery. If Lithium Ion type battery is selected, it must utilize
an integrated battery management system (BMS) to protect the
battery cells from inappropriate voltage or current levels.
