Black Start
Black Start is a wake-up function for when the Home 8 is in sleep mode.
The Home 8 will go into sleep mode to protect the battery from over-discharging when the SoC of
the Home 8 has reached 0%. (e.g. In case the surplus energy from the PV system is not enough to
charge the battery during a power outage.)
The user or installer should press and hold the BLACK START (6s) button for more than 6 seconds
when the battery can be recharged by the PV system or the utility grid. If 2 or more Home 8 units are
installed, press the BLACK START (6s) button on each Home 8 unit.
This feature could be still used in a power outage. In general, during a power outage, the PV system
will not operate if the Home 8 is in sleep mode due to reaching 0% SoC with no backup power. In this
case, however, the user or installer can wake up the Home 8 in the morning, and then the Home 8 will
be charged from the PV system WITHOUT supplying the backup load. Once the SoC of the Home 8
has reached the specific SoC level and has met other conditions, the system will automatically supply
the backup power to the backup load with the PV system.
The user or installer should wake up the Home 8 even though the utility grid has been recovered after
the Home 8 is in sleep mode. In this case, the Home 8 will be charged from the utility grid up to the
specific SoC level and the system will automatically operate following the pre-set operating mode.
y
SoC 0 % means the battery has run out of capacity. When the SoC reaches 0 %, an alarm is
sent through EnerVu and the LED Indications display 0 %.
y
When running the Black Start function, the battery will first start charging, and after a
certain amount of charging, the system will operate normally using battery power.
y
Before pressing the Black Start Button, make sure that the PV is operating normally.
