● This Hybrid Wind-Solar 1680W 48VDC power system is designed to be used off-grid or on-grid as backup. On-Grid – Utility Grid power is available and can be used to recharge batteries but an "on-grid" inverter will not export power.
One of the most important considerations is siting. General industry standard is 30 ft. above obstacles within 300 ft. Obstacles in the primary wind energy direction have an increased impact on the production of a wind turbine by altering the resource or increasing turbulence. There are multiple ways to help avoid this potential conflict, including siting the turbine in a more open area, locating the turbine upwind of obstacle(s) to the prevailing wind direction, or increasing the tower height. Poor siting not only affects production and wear and tear on the turbine, but also the experience and overall satisfaction of wind as a viable power generating source.
To avoid air turbulence, wind turbines should be placed on a tower high enough that the bottom of the turbine rotor’s swept area is at least 20’ to 30’ higher than any buildings, trees, or other obstructions within a 300’ to 500’ radius. If the wind at the site primarily comes from a particular direction, and the obstructions are not in the wind path, then less clearance may be allowable as long as the flowing air is laminar. In the illustration below, a kite with long streamers tied to the line at 10’ intervals can be used to find the height above ground level where the air flow smooths out. Look for the first streamer to be fully furled out.
The distance from the tower to the battery bank needs to be taken into consideration. This will dictate the size, length, and therefore the cost of wire. Locating the turbine and tower should be thoroughly thought out with attention to: the ease of access between the two for possible trenching, potential traffic, direct burial cable or conduit, junctions or splices, and safety. The proximity to property lines and surrounding area to accommodate access to the turbine, whether the tower is tilted down, or serviced by a lift will also affect tower location.
There are different types of towers onto which a wind turbine can be mounted. These include: lattice or truss type towers, stand-alone towers (monopole), guyed towers, and homemade. There are pros and cons associated with each as well as applications. Some considerations are:
● Guyed towers are relatively inexpensive, easily raised and lowered, can be assembled onsite, but require a larger foot print.
● Stand-alone (pole) towers are generally more attractive, no guy wires, have height limitations, and require extensive foundation and concrete work prior to installation.
● Lattice or truss type towers generally are climbable, can be assembled onsite, require concrete, a larger base footprint, and possibly guy wires.
Wind speeds are highest during the winter months when solar resources are at their minimum Air density is highest in winter maximizing wind power production wind provides power during inclement weather when sunshine is not present wind provides power at night
● Winter wind speeds primary focus in winter because the mean upper-air wind speeds are stronger than in any other season over most of the contiguous United States.
● Regions in white; Typically solar only regions. Regions in light blue; Hybrid solutions should be analyzed. Light blue to dark blue; Hybrid solutions strongly recommended.
In most instances, solar is utilized as a power generation medium for off-grid applications. Primus Wind Power and Blue Pacific Solar are advocates for wind to be used in conjunction with solar for system redundancy, more uniform power generation, and reduced depth of discharge. AIR is a suitable complement for nearly any off-grid power system where solar is being used.
● Energy loads that are necessary in the wintertime and nighttime off-grid should represent a wind component using the AIR 1-AR40-10-48 turbine. A prime example is heating, where the load is increased in the wintertime (due to longer nights) and where energy generation is a complement to solar during the nighttime when wind power generation can occur and solar power generation cannot.

Primus AIR 40 is the premier micro-wind turbine for land-based applications. It operates efficiently across a wide-range of wind speeds and is ideal for pairing with solar to offset seasonal variation, delivering more consistent energy. The Magnum inverter produces pure sine wave clean electricity drawing power from the energy stored in a battery bank. Mechanically and electrically engineered, every component has been specially selected to assure the highest performance with this safe simple-to-install kit.
The hybrid Wind-Solar 1680W 48VDC off-grid kit is ideal for applications with small to medium power requirements such as off-grid cabins, homes and back-up power systems.
The AIR 40 provides energy for off-grid homes, water pumping, lighting, telecom, and anywhere you need electricity and have average annual wind speeds under 15 mph. It has a bare aluminum finish for use in non-corrosive environments, so it is not suitable for marine use. The AIR 40 is rated for 160W at 28 mph (12.5 m/s).
The all-new Air 40 is quieter, more efficient, and precision engineered to deliver more energy at lower wind speeds than any other wind generator in its class. Air Breeze is the next generation of Air turbines with more than 100,000 units sold in 120 countries, the world's most popular small wind turbine.

The 27’ and 45’ tower kits come with all the hardware necessary to install a tower, except guy-wire anchors, pipe, and concrete. All parts bolt or clamp together, and no welding is required. Purchase 1 7/8” steel tubing from a local chain link fence supplier (for up to 90 mph at 27’, or 70 mph at 45’), or use 1.5” Sch 40 Galvanized water pipe (1 7/8” OD and up to 120 mph at 27’ and 90 mph at 45’), to build the tower. These tower kits include a simple elbow/tee for its base that, when combined with a short length of pipe, eliminates the need for a concrete pad, swivel, and base plate. Two people can erect one of these towers without using winches or vehicles.
The 29’ EZ Tower™ kit comes with all the parts you’ll need, including Galvanized tubing, cable and hardware. This tower uses lightweight tubing while providing plenty of strength to withstand winds up to 110 mph. Two people can easily erect the EZ Tower™ without winches or vehicles. The EZ Tower™ includes a simple, yet effective, tower base and anchoring system which eliminates the need for a concrete pad. The kit comes with guy-wire anchors that are driven into the ground (depending on the soil conditions, concrete may be necessary for proper guy anchoring). Can ship via UPS in one 74” (1.9 m) box weighing 80 lbs.
The Primus Wind Control Panel (WCP) is a low cost analog control panel for use with AIR Breeze and AIR 40 12, 24, and 48 VDC and AIR X Marine/AIR 30/Silent X 12 VDC wind turbines. The WCP controls and monitors the AIR wind turbine and is equipped with a power On/Off circuit breaker, analog ammeter (indicating wind turbine current production) and a Stop/Run switch (for direct control of the turbine). A clearly marked rear terminal block is provided for easy interconnect of the two turbine wires and two battery power wires. It is available in a 25 A version for 12 VDC systems, a 10 A version for 24 VDC systems, and a 5 A version for 48 VDC systems which are fully calibrated and ready for installation. The panel measures 3.5” x 5” and the Surface-mount black plastic enclosure allows for mounting of the WCP on a flat surface.
The 30 A ammeter is an analog meter for measuring the output current of the AIR turbines. Analog meters are recommended for wind turbines as digital meters tend to scroll too fast in uneven wind to read properly.
Augers - If the soil conditions make their use feasible, augers are the simplest anchors to install. Augers screw into the ground by use of a piece of wood, pipe or rod as a “cheater bar”. If a mistake is made or if the tower must be removed an auger can be “unscrewed” out of the ground and reused. Augers depend on the soil holding together for their strength and are not suitable for sand or loose gravel. If the soil is rocky or clay-like you may have difficulty screwing them in. An auger is usually installed by screwing it straight into the ground a few inches to get it started and then tilting it to the desired angle and continuing. A substantial downward pressure is usually necessary to get an auger started. Screw the augers in as far as possible for the greatest strength.
