The Air 303 (300-watt @ 12vdc) wind generator is mounted on top of a 30 ft. section of 1 1/2" galvanized pipe. The pipe runs through the roof and is attached to the side of the house. The solar array consists of 4 Siemens SP75 (75-watt) modules, wired to produce 17.6 amps of charging current in peak sun. 

This owner-built log home is located near Fair Haven, Vt. Power needs are kept to a minimum by employing non-electric major appliances, namely a propane refrigerator, wood burning furnace, and a composting toilet. The water system includes a 1/3 hp deep well pump, powered by the Xantrex inverter. 

The owner has decided for now not to invest in a back-up generator, meaning the wind and solar must generate 100% of the home's power requirement. It is rare for a generator to be lacking in a full-time residence. But the need for power here is modest, and the small wind generator supplies ample power during the windy winter months, when a generator would run frequently to accomplish the same task.
The inverter and controls are located in the basement. A 250-amp DC disconnect breaker provides overcurrent protection for the Xantrex DR2412 inverter. The PV array current is regulated by a Xantrex C40 controller. The wind generator is protected by a 30-amp fused disconnect switch. Lightning is a legitimate threat to metal wind towers, so precautions must be taken. The wind tower is to an earth ground at its base, and wind and solar inputs are protected by lightning arrestors on the control board. 

The battery bank includes 8 Trojan T105 6v, 220 ahr batteries, wired for a total of 880 ahr @ 12vdc. These deep cycle golf cart batteries will typically last 5 years before replacement is required.  A Bogart Tri-metric meter is mounted upstairs in the kitchen for convenient monitoring of battery voltage, current, and state-of-charge.
