1 | BMS | | Global Normal | 12/30/2021 | 12:33:00 | 12/30/2021 | 16:39:00 | The 2-axis tracker failed under high wind conditions and is facing in a north east position, data from the following instruments should not be used until repaired:: Global Normal CMP22, SP-Lite2, LI-200R, WISER. Tracker was power cycled after the wind died down to force it resume normal tracking operations. |
2 | BMS | | Global Normal | 12/15/2021 | 08:00:00 | 12/16/2021 | 08:25:00 | The 2-axis tracker failed under high wind conditions and is facing in a north east position, data from the following instruments should not be used until repaired:: Global Normal CMP22, SP-Lite2, LI-200R, WISER. Tracker was power cycled the following day (with sun sensor disconnected) to force it resume normal tracking operations. Sun sensor is now connected and it seems to be working. |

25 | BMS | | Global Normal | 11/01/2000 | 00:00:00 | 11/07/2000 | | The LI-COR LI-2020 Solar Tracker is powered by a PV panel with backup battery, however the charging cycle does not work correctly. Therefore the battery does not recharge after cloud cover and the tracker stops. The battery has to be (manually) swapped with another charged battery, until the problem is corrected. |
