Utility Bill
Reduction + Back-up Power Value Package
2
kW HomeSure Package
Performance:
160 - 400 Kilowatt-hours (kWh's) per month (depending on wind resource),
12 hours to over a week of back-up power (depending on load and
wind)
Recommended for: Areas where power outages are a problem
Smaller essential loads
Property sizes of 1/2 acre or more
Locations covered by 35 ft. tower height limitations
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, but don't need a system
as large as the 7.5 kW HomeSure system. This capability requires
the addition of batteries and a sophisticated inverter.
The
HomeSure 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 64 ft towers because this is the most common tower
height for the XL.1 turbine. The taller the tower the better
and towers shorter than 64 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 Trace SW4024 sine-wave inverter provides
120 VAC (or 230 VAC, 50 Hz at 2.2 kW) and has enough surge capacity
to start motors up to ~ 1 Hp. (Note: We have switched from the Trace
PS 2524 2.5 kW inverter to the larger 4 kW Trace SW4024 inverter
because Trace has dropped the grid-intertie feature on the PS2524).
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 $1,000 (customer installed, no sales tax, etc) to $4,000
(Certified Dealer, sales tax, etc).
