Reason for Report: Routine
Non-Nominal Systems: Crew car. Power system battery, invertors, generator. Robotic observatory. HAB outer shell.
Power system:
Solar: The battery bank does not hold charge when the sun is down and low on the horizon. Inverter Slave 1 and 2 went offline and did not restart, which limits us to 5kW when on solar.
Main generator has been monitored for oil leaks; minor leaks observed, need to add oil every 2-3 days. Generator is limited to 8kW, see previous reports for details.
Main generator:
1) Oil, oil filter, changed on 02/13/2025, 8408.4 hours.
2) Current hours – 8447.0.
