|7.5 kW Home.Sure Package|
|Performance: 600 - 1,500 Kilowatt-hours (kWh's) per month (depending on wind resource), 24 hours to over a week of back-up power (depending on load and wind)|
|Note: This system contains batteries and can provide essential household power during power outages.|
We recommend this package for homeowners and small businesses that want protection from extended power outages. This capability requires the addition of batteries and more sophisticated inverters.
The Home.Sure system keeps the batteries charged up and during an outage home power is supplied by both the batteries and the wind turbine. In regular (non-outage) operation any excess energy, once the batteries are charged, is sold to the utility company or "stored" by utilities offering net metering. The Guyed-Lattice tower is the least cost tower type and a 100 ft. tower is tall enough for most locations. Shorter towers reduce performance and increase the payback time.
The batteries are Trojan L-16's, the workhorse of the home power industry. A total of 40 individual batteries are connected in five parallel strings of eight batteries in series (48 VDC nominal). This large battery bank will support essential loads (lights, radio, TV, refrigerator, freezer, water pump, and blowers) for two to seven days without wind energy input. The dual Trace SW5548 sine-wave inverters provides 240 VAC (or 230 VAC, 50 Hz at 9 kW) with enough capacity to start difficult motor loads. A back-up engine generator can be easily added.
In addition to the equipment costs given below, a complete installation will typically include the following costs: shipping, sales tax, permit costs, foundation and anchoring, wire run, turbine and tower erection, battery racks or vault, electrical hook-up, and inspection fees. Some homeowners also incorporate a back-up gas, propane, or diesel generator into the system for maximum protection. Your dealer or Bergey WindPower can assist you in budgeting these additional costs. For budgeting purposes, these costs typically range from $5,000 (customer installed, no sales tax, etc) to $20,000 (Certified Dealer, sales tax, diesel generator, etc).
