Models

There are four standard Hummingbird Models:

5kW OFF GRID 5kW GRID TIED 10kW OFF GRID 10kW GRID TIED This manual will be focused on the grid tied models, but a brief explanation on the functioning of the off grid models is provided as well. The off grid model, as the name implies, is for use in remote areas where a utility service does not exist or whereindependence is sought and the unit will “stand alone”. Wind energy from this model should be stored in a battery bank because of the manner in which the energy is captured and used. In effect, the off grid model is a system especially designed to charge or supplement a battery bank for maximum utilization.

The grid tied model is for use where a local electric utility operates and interconnection issought. Wind energy from this model is designed to tie-in to the utility through an inverter and supplement or substitute energy consumed from the utility. In windy areas the Hummingbird could produce more energy than consumed, resulting thereby in a favorable balance of energy for the owner of this unit. It is important to remember that the utility should always be notified and consulted beforeany connection can be made.

Applications The following is a list of some applications for the off grid and the grid tied models. Grid tie applications include: Farms Homes Offices Truck stops Service stations Clinics Illuminated signs Off grid applications include: Isolated homes, cabins, farms. Communications facilities, attended or unattended. Above and below ground water pumping. Highwayrest stops, parks, recreation areas. Resistance heating for liquids and air. Lighting and radio power for drilling rigs. Island power and light. Water desalinization and refrigeration. Offshore platforms. Illuminated signs.

Theory of Operation

OFF GRID Model The theory of operation for the off grid model can be best described by figure 1.

DIAGRAMA DE OFF GRID Figure 1 When the wind is equalto or greater than 7MPH, the Hummingbird will produce usable electric power which can charge a battery bank. The application of this model necessitates the use of sufficient storage batteries to supply power during periods when the wind is low and/or to provide peak power requirements. Power can be taken from a DC bus connected to the battery bank, for a stable and constant electric power supply.Many heavy electric loads can be directly connected to a 110 volt DC supply. Incandescent lighting (standard type light bulbs), resistive heating elements (such as hot water heaters), and appliances having “universal” type motors, such as hand drills, hand saws, kitchen blenders and mixers, vacuum cleaners, etc.,

can usually be directly connected. Before connecting these types of appliancesto a 110 VDC supply we recommend the manufacturer of the appliance be consulted. Other heavy duty loads, such as DC motors coupled to pumps, can be connected directly to this DC bus. NOTE: Special 110 DC switches must be used for these direct connections. AC loads, such as stereos, radios, televisions, refrigerators, washing machines, etc., should be connected to a DC/AC inverter. An inverterconverts DC to AC through electronic circuitry.

GRID-TIE MODEL The theory of operation for the grid-tie model can be best described by figure no. 2.

There are various ways of connecting a Hummingbird grid-tie model, depending on the local utility’s requirements. Some utilities will ask for the installation of a separate watt-hour
