I brought the three batteries last remove from HS and put them under the solar panels. I rewired all the panels into a terminal strip. I used one of the old batteries for the fence charger and brought the rest in. |

This battery bank had been without batteries since its batteries were moved to the Tower a few weeks ago. I installed three old batteries from the Floor system that tested ok with the load tester. I rewired the two larger solar panels to 12V. The two smaller panels had there leads chewed and I left them disconnected for now. |

The batteried in this bank have been temporarily removed to power the Tower. Likely this bank will be repopulated to power the OSU-SP1 system and a couple FD chambers as the Vaisala soil CO2 system is decommissioned. |

Six old weak batteries (four currently connected) were brought back to the lab and four new Duracell deep cycle flooded group 27 batteries were installed in pairs for a 24V system. The new batteries have 09/19 (Sept/2019) stickers. |

There are six batteries in three pairs for a 24V system – the original four plus two more we added last winter. Two of the originals test a little weak with the load tester so I disconnected them from the bank. |

This system has been failing overnight partly because one set of Vaisala probes have not been cycling off. I also added to old batter most recently used on East End. |

I moved and combined the east 24V system with the west 24V system. Four panels in two pairs now feed two pairs of batteries through one charge controller. |
