Using patented technology, we have the ability to improve the performance of our wind turbines by 20% to 30% using sails that stabilize the von Karman vortices.
Our turbine module houses all of the components to combine multiple units and to then deploy in any configuration. This module is designed for low wind regimes present in most urban and suburban environments. Depending on the annual average wind speed, it could be configured as a three-, five- or seven-blade module.

The Nacelle contains all the necessary hardware and software to convert the wind's energy to electrical power with the output voltage holding steady at 30V and a current ranging from 0 to 10A. In addition, the Nacelle houses the BreezeBox and BrakeBox modules.
The metal housing is zinc plated, epoxy dipped and powder-coated. This provides a NEMA-4 (IP65) type housing that is guaranteed for 15 years. The AutoFurlz function is designed to be activated at 35 MPH for the seven-blade rotor and is in integrated into the nacelle.

The Nacelle for the JLM turbine is designed to be mounted using a virtually limitless number of techniques. Flexible installation is at the core of our philosophy for providing attractive turbine arrays.
Here are some of the standard techniques for installing our turbines...
Parapet Mount: Most commercial buildings are constructed using either the concrete tilt-up technique or CMUs. In both cases the top edge of the wall extends past the roof line of the building. The exposed roof edge is an ideal location for installing the turbines using the parapet mount. Additionally, the Parapet Mount can also be used to install the turbine on the inside edge of the wall to hide the base. The base footing measures 6" x 10" and the holes are 3.5" x 8" on-center, respectively.
Tall Parapet Mount: The tall parapet mount is 3' taller than the standard parapet mount. It is used to double turbine density along a roof line by being able to add units between turbines using the standard parapet mount.
Wall Mount: Wind turbine arrays are installed on or behind a wall using our wall-mount turbine stand. Note that the base is adjustable to any angle 90 degrees. The base footing measures 6" x 10" and the holes are 3.5" x 8" on-center, respectively.
Roof Mount: JLM's Roof Mount is used in situations where protruding the roofing layers is not acceptable. The base frame measures 8" x 8", it supports two turbine modules and can be anchored down using sand or gravel bags. This mount is often used when installers are optimizing the siting for the turbines.
When using the parapet mount, our most common of mounts, the turbines can be placed no closer than 4'-6" from center to center. Our tall parapet mounts enable you to double the density of turbines along a roof-line making each turbine only 2'-3" from center when alternating between tall and short parapet mounts.
Since the Small Wind Certification Council (SWCC) does not recognize the array configuration, qualifying our wind turbines using a single string inverter would be impossible. On the other hand, our customers are excited to use multiple wind turbines, configured in an array, to produce a substantial amount of energy. To provide maximum flexibility in configuration and installation of our arrayed wind turbine technology, each Zefr wind turbine interfaces with its own dedicated micro-inverter. The micro-inverter technology, while common in the PV Solar industry, has never been used in wind turbines due to complex technology barriers. JLM's Zefr is the first wind turbine in the world that has been successfully interfaced with a micro-inverter. The micro-inverters used by JLM are UL1741 / IEEE1547 certified and are warrantied for 5 years. In addition, they are compatible with 208V, 3-phase or 240V, single phase grid configurations.
Given the widespread use of these micro-inverters in the PV Solar industry, configuring a hybrid system of wind and solar panels has never been easier. The AC-SGB monitoring module is configuring to not only monitor the production of the wind turbines but also keep track of PV Solar production, as well.
