Thursday - Something I didn’t expect to be concerned about. Low-temperature solar panel voltages. The open circuit voltage, Voc, is specified at 25°C. The voltage increases as the panel temperature drops. On the colder days, you can see that the PV voltage for the four panels is in the mid-90s. Under normal temperatures, it’s in the mid-80s. The maximum input voltage for the Victron 100/50 solar charge controller is 100V. I thought that I had plenty of room but maybe not. If colder temperatures are in the forecast (during the day), I’ll need to disconnect the panels from the controller.
Friday - This morning, the RV park had breakfast available. Not bad and it was an excellent opportunity to visit with others in the park. Around noon, I went to the hot tub as the temperature was already well into the 50s and sunny. Pretty nice.
Yesterday evening, we went to visit friends staying at the SKP park. We visited with them in Casa Grande a few weeks ago and we had originally met them on the Oregon coast a few years back. It was nice to see them again.
There is a test session this afternoon so I’ll probably participate today. Other than that, a pretty slow day.
