The IQ Battery system includes the battery cellpack with integrated IQ Microinverters and battery management system (BMS). The system requires
IQ System Controller for grid-tied and backup operations. The IQ Gateway inside IQ System Controller measures PV production, IQ Battery charge/discharge
power and home energy consumption, and it senses when it is optimal to charge or discharge the battery so that energy is stored when it is abundant and
used when it is scarce.

E. OPERATION
aLED overview
After being commissioned, the LED ashes yellow while each IQ Battery
boots up. If the LED rapidly ashes green for more than two minutes,
the battery is in trickle charge mode and will remain so until it reaches a
minimum state of charge (up to 30 minutes). After the IQ Battery is booted
up, the LED becomes blue or green depending on the charge level. If the
LED ashes yellow after one hour or changes to a ashing red state, contact
