The button battery in controller
is missing or failure.
The power supply in controller
is failure
The battery voltage is too low.
The connector of base is failure
Self-checking failure.
DC side has a voltage, but
voltage difference with the
battery system is higher than
20V.
BMS internal failure.
The time interval after last time
black start is too short.
The battery system under error
condition such as: temperature
or current protection or other
error, thus do not response
black start.
