|---|---|---|---|---|---|
| SP75 020854E-6-03-02-06905 | 2022-05-04 | Lab none | Repair | Lab none | This panel had been under (salt) water at Yampah. The junction box on the back was all rotted out. I scraped the box off and the four junctions to the two 6V cell strings were still good. I soldered wires to the junction pads and added a screw terminal with two diodes. The panel was 20V and 4.5A in the sun. I cut the structure out of the junction box and reglued it to the back on the panel to protect the wiring and screw terminal. I think this panel is good to go. |
| PS-30M 186580399 | 2022-05-04 | Lab none | Disposed | Disposed none | I took this controller apart and discovered that it had been partially submerged in salt water at Yampah. I cleaned it up as best I could and connected it to a battery. It's bricked - not even a puff of smoke. Put it in the e-waste box. |

| LI-7700 TG1-0421 | 2022-04-15 | Lab none | Tested | Lab none | Plugged it in in the lab. The power LED was blinking intermittently and the ethernet and status LEDs were off. The fuse and fuse connector were totally rotten and the inside of the sensor body had condensation and a few tsp of water. We didn't see any obvious corrosion on the other circuit boards and no obvious leaks/cracks in the sensor. We wiped up the water and will let it air dry before sending it back to Licor. |

In the lab the SS was much more normal ~100. I'm not sure why there is a difference, as the config file should be the same. |
| PAR-LITE 040411 | 2022-01-20 | Lab none | Damaged | Lab none | Brought to EE to install as part of the dfPAR set up, but killed the sensor when I accidentally wired its red/black wires into power |
| WM 1590 153804 | 2022-04-06 | Lab none | Tested | Lab none | I tested this sensor briefly in the lab against sn 152601. U and V had a much smaller magnitude. I checked the analog settings and they had been set to 5m/s range. I changed U and V from 5m/s to 30m/s. I left W as 5m/s. U, V, W, SOS seem reasonable. I will be moving this intercomparison to my backyard tomorrow to run for a few days outdoors. |

Seems stable now but I'll test it again in a few days to confirm. |

The sensor seems stable now. Swapping the chemicals seemed to fix the issue with the large H2O zero offsets. |
