Log Book for March 25, 2008
Engineering Report
Elisha Sanders Reporting


Generator/Electricity:

Wendy

Hobbs Meter: 3881.1 hrs [ +22.5 hrs since yesterday ]

Voltage: 120 VAC

Frequency: 61 Hz

Oil Level: 3/8

Oil Pressure: 30 PSI

[*] Water Drained: no


Notes/Comments:
While pumping water to the inside tank the flow stopped midway through.
Checking the generator the frequency gauge was wildly bouncing around.
During this time the water would not flow. After turning it off and
restarting the generator the frequency finally settled down and flow
resumed. During all of the fluctuations the inverter never indicated a
problem in the power coming from the generator. Also the flow would
stop while the microwave was running (total load: 17.5A).


Xantrex Inverter/Dynasty Batteries:

GreenHab:

Crops Watered: yes


Crop Condition:
Lettuce is wilting, corn browning at edges. Cilantro turning red, dill
yellowing, radish leaves turning brown. Overall things look to be
uniformly drying out. We have totally turned off both heaters on each
side (internal temp in the low 100s). We are going to water as needed
everyday until crop condition stabilizes.
