It looks like they have everything still on full power.
*On Friday afternoon (11:55 am Houston Time), power channel 1B experienced
an electrical event that telemetry points to a fault in the power channel’s
Sequential Shunt Unit [SSU]. An SSU is responsible for regulating the power
voltage levels generated by the solar arrays before it is passed to systems
downstream,” NASA’s Dan Hout told SpaceFlight Insider. “A seamless power
transfer was performed to recover loads from channel 1B to channel 1A.
Currently operating on seven of eight power channels, no impact to station
systems or operations. Crew was never in any danger.*
