| PS-30M 02431248 | 2016-03-08 | Tonzi-Tower | Removed | Lab none | This charge controller was at the Tonzi Tower. It could not read the battery bank voltage and had shutdown the load with a Low Voltage Disconnect message. I removed it and replaced it with the controller from the Tram system sn 0135002X |
| PS-30M 0135002X | 2016-03-08 | Tonzi | Moved | Tonzi-Tower | I moved this charge controller from the Tram solar system to the main Tower power system. The existing charge controller at the tower sn 02431248 stopped reading the battery voltage. |
| BB-Fab BB-EE | 2015-12-08 | East End Battery Bank | Upgrade | East End Battery Bank | A third solar panel was added to this solar system. |
| BB-Fab BB-EE | 2015-11-20 | East End Battery Bank | Upgrade | East End Battery Bank | I added the two batteries recently removed from Alfalfa. These two batteries had Jan 2012 stickers and tested okay in the lab. I charged them up in the lab before taking them to the field. The other four batteries at East End also had Jan 2012 stickers and I think the two I added were originally at this tower or the Corn tower before. |
| BB-Fab BB-EE | 2014-03-07 | East End Battery Bank | Moved | East End Battery Bank | The battery bank and solar panels were moved from the south side of the tower to a new scaffolding to the south of the tower. |
| BB-Fab BB-EE | 2013-11-25 | DWR Corn Battery Bank | Installed | East End Battery Bank | This is the initial installation of this battery bank for the East End Tower. Four batteries were brought from the DWR Corn Construction tower and installed at this tower. The batteries are on a boardwalk on the ground next to the tower and will be moved to secondary scaffolding later. |

| PAR-LITE 010163 | 2015-03-05 | Lab none | Installed | Mayberry PAR Sensor Reflected Veg | Installed on the Mayberry tower (over tules) but it was reading high when it was connected to the multiplexor. The mux channel was even read high when jumped - so may be bad channel on mux. The PAR sensor was left on the tower and the mux or program will be changed to deal with the bad channel. |
| HP-127-1.0-1.3-71P P01 | 2015-12-21 | Lab none | Repair | Lab none | The red lead looked chewed and was broken at its junction to the plate. I soldered a new red wire directly to the junction and a new black wire about 3cm from the plate. Both wires were covered with heat shrink and the junctions to the plate were painted with black Rustoleum paint. |
