We
recommend this package for homeowners and small businesses that want
protection from extended power outages, but don't need a system as large
as the 7.5 kW Home.Sure system. This capability requires the
addition of batteries and a sophisticated inverter.
The Home.Sure system keeps the batteries charged up and during an outage
home power is supplied by both the batteries and the wind turbines.
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.
This package uses 60 ft towers because this is the shortest tower
height for the XL.1 turbine. The taller the tower the better and
towers shorter than 60 ft. should only be used in special circumstances. The Tubular Tilt-up towers can be installed
without concrete and they tilt-up after all the assembly work is done on
the ground.
The batteries are Trojan T-105's, a workhorse of the home power
industry. A total of eight individual batteries are connected in two
parallel strings of four batteries in series (24 VDC nominal). This
battery bank will support essential loads (lights, radio, TV,
refrigerator, freezer, water pump, and blowers) for 4 - 12 hours without
wind energy input. The OutBack GTFX2524 sine-wave inverter
provides 2.5 kW at 120 VAC (or 230 VAC, 50 Hz at 2.2 kW) and has enough surge capacity to start motors up to ~
1 Hp. 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 $3,000 (customer installed, no sales tax, etc) to $9,000
(Certified Dealer, sales tax, etc).
