D'Hanis, TX - SKP

Tuesday - Still kinda rainy today, so no A/C cleaning. At least in the morning. The cold front that brought all the rain has also meant cooler-than-normal temperatures. I'm not going to complain about that. 

The Raspberry Pi that was running the Victron Venus OS was getting really flaky. I removed the SD card, which was a really old 8GB card, and installed the current version of the OS on a newer 32GB card. It now works (so far), and the touch screen seems to be much more responsive. It’s talking to HomeAssistant again, using ModBus as well as the Victron VRM portal. It hasn’t done that in months. 

Wednesday - No rain this morning, at least for a while. I pulled off the A/C shroud on the rear unit and brushed the fins clean using the special, plastic brush on the can lid. It did a good job. After vacuuming up the pile of debris, I sprayed on the cleaner and let it sit. After about 20 minutes, I sprayed off the evaporator with hot water in a spray bottle. It now looked new. 

I removed the shroud on the front A/C unit to see if it was equally dirty, but it was clean. I then buttoned everything back up, turned on the power to both units, and waited until it warmed up. It didn't take long. By 11:20, it was over 75°F inside, and both A/C units came on.

I then joined in for the mid-day test session. There was a shortage of VEs, so we ended up testing the two candidates serially. 

I picked up 1½ gallons of gas for the Ural. It started right up, but at 81°F, it was feeling too hot to go for a short ride. Wimp…

Thursday - I finished setting up the RV this morning after taking the Ural for a test ride. The Ural really seemed to need the blast up and down the highway and was running much better when I returned. And this is with Stabil added to the remaining fuel in the tank. 

I am pleased to report that it looks like the power problem with the class A has been resolved. Turning down the absorption voltage on both the inverter/charger as well as the solar charge controller eliminated the 12V "blinks" and the inverter shutting down. 

I'm in the shed right now, getting ready for the midday test session, and have the room A/C running. It seems to work well enough. It is forecast to be very warm this weekend.
