Frozen pipes and burn piles, spring after a frozen winter

I finally got away from work and took one of the kids down to the Cabin. Winter started in earnest about Thanksgiving and only now really started to thaw. There are a few patches of snow left.

The temps hit 0F at least three times this winter. One of the few pieces of PVC that exist in the water system froze and cracked.

For late February, the ground is also thawed out too. Very wet, but not frozen. It’s not feasible to burn brush and rotted wood in the summer and fall. Pretty much exclusively in the winter. I managed to take of about a third of a burn pile.

Also upgraded the firmware on the Midnite Classic 200. I waited right up until the deadline to do the upgrade. A few new pieces of data are available via the cloud portal, such as the Wiz Bang Jr’s amp rating.

On the way back to the valley, stopped by Odell Lake and took a few photos.

This tree nearly destroyed the cabin

We arrived for a relaxing weekend to see this 50+ foot ponderosa came down inches from the cabin. It is feet from the propane tank, and inches from the house itself; missed the pump house by three feet. This time of year the ground should be fully frozen, but this is a very dry year. Compared to years past there was very little snow fall. The Friday night we arrived, it rained about an inch. The rain is welcome, but it is loosening the root structures of the trees at a time when there is much more wind. Since December at least five trees have come down.

6m opening from the Cabin

The night before we had to leave the cabin there was a nice 6m opening to DM04, DM13, and DM14. I configured my Buddipole with a two element yagi and ran about 50 watts from the Elecraft K3. Received signal reports from 54 to 59 from those grids. Worked about a dozen stations and even received a nice QSL card from K6JAD.

Washing clothes off grid

Today the kids got dirty. They love playing in the dust, dirt, and digging holes. We dug out the base camp counter top clothes washer. This is the first time we’ve used this. Filled it with hot water, dirty kids clothes, high efficiency detergent and let it run.

This thing is noisy! The mechanical timer by itself is noisy. The agitator is noisy. Our kids clothing was so dirty, I gave up after rinsing three times. This makes me wonder how much water we use at home washing kids clothing.

Expanding the battery bank

We are expanding the battery bank to three strings of batteries. The primary reason for doing this is to decrease the cycle depth. The bank typically drops to 12.6v each night. My goal is to get this closer to 12.7v to 12.75v. Two more DC335-6 batteries will bring the capacity to ~1000ah at 20C discharge rate. A 20C discharge rate is 50amps per hour for 20 hours. I figure on average our consumption is 10 to 15 amps per hour.

Burn piles

Spent some of my down time cutting up fire wood. I’m slowly reducing the burn piles. I’ve had these piles for two years now. The burning season is really restrictive (my own standards).

Power efficient refrigerator for off grid use

As the cabin runs exclusively on solar power, a normal refrigerator would not work for us. Typically refrigerators use 0.75 to 1.2 kw of power per day. I’ve read that a chest freezer can be converted to a refrigerator by using an external temperature control and running the compressor until the desired temperature is achieved. The energy conservation comes from the chest property that keeps the cold in.

I purchased a [very small] 2 cubic feet chest freezer at my local Bi-Mart. I got the last Arctic King (made by Midea) model ARC21MW. The label on the back states it is consumes 86 watts. I bench-marked the inrush power at about ~300 watts. Using a Johnson Controls Digital Thermostat Control Unit set at 35F, I found the unit consumes on average 7 watts per hour and about about 168 watts per day.
