Summary: Checked solar charge controller and batteries

2020-03-11
Sherman Wetland

Joe and I arrived at 15:25 PDT. It was a mild and breezy day with blue skies and low cumulus clouds. The water level was 83 cm.

Joe checked the solar charge controller and batteries, because the power has been spiking down below 12V and weâ€™ve been losing data during the day. The charge controller screen was all black, and there was no change when it was restarted. Joe will look into upgrading the charge controller firmware.

I downloaded met data. The eosGP CO2 and T data are still spiky. I pulled the sensor out of the water, removed the mesh, and swished the sensor around in the wetland to rinse the little bit of duckweed and critters out. I put the mesh back on and lowered the sensor again. Iâ€™ll keep an eye on it. I wonder if it's related to the power fluctuations.

We left at 15:55 PDT.
