| Battery Bank | |||||
| 2014-09-10 | BB-TW | BB-Fab | Upgrade | We moved the three old group 8D out of the way and installed the four group 27 batteries. I had two older batteries in the lab and bought two more. We also installed a new solar charger under the solar panels. | |
| 2015-12-28 | BB-TW | BB-Fab | Upgrade | I added two batteries to the battery bank. I added two batteries from the lab. One form 5/14 and one from 5/11. Both tested okay in the lab. The existing batteries were two from 2/12 and two from 6/14. | |
| 2016-01-12 | BB-TW | BB-Fab | Lost | The old 8D batteries, the solar charge controller were stolen along with the old solar panels that were on top on the big box. Power is down until the charge controller can be replaced. | |
| 2016-01-21 | BB-TW | BB-Fab | Repair | The solar charge controller was replaced. | |
| 2017-06-01 | BB-TW | BB-Fab | Removed | The Twitchell Rice solar system was disassembled and removed. Two of the batteries were dead and will be recycled. The four other batteries load tested okay and were taken to Tonzi for the Floor solar power system. The solar panels and charge controller were removed and will be used at the temporary tower at East End this summer. | |
