FAQ D-series

The reinforcements of the individual systems were simplified in order to make it easier to construct the foundations and thus save on costs and time. With introduction of the new systems there will only be two different reinforcements. Please consult our technical documentation for more information. In addition, we offer a prefabricated reinforcement cage for all systems as an option.

The following materials are to be provided for assembly by the owner:
  • lifting equipment for unloading (fork-lift truck, crane)
  • at least nine pallets or squared timber
  • torque wrench and screwdriver
  • crane for assembly of the frame member on the mast
  • 12 to 24V DC battery pack
  • ladder, work platform or hydraulic platform
  • GPS device or compass
  • battery-operated drill
  • cordless screwdriver

In order to eliminate any ambiguity only the length of the supplied masts will be indicated in the future. Please see our module layout for the height of the system in storm position and/or the maximum system height up to the upper edge of the module surface.

Through the greater elevation range of 10°-90° and the substantially more compact transmission, the distance between the subsoil and the lower edge of the module surface is reduced. In order to compensate for this the new masts had to be longer.

The area between the mast and the module surface is clearly reduced through the greater elevation. Thus there may be collisions in individual cases. In order to prevent this, a defined restricted area must be taken into account. For more information please consult our assembly instructions.

With the borehole in the mast you can route the wiring from the mast in order to distribute it further. Assembly thus becomes much easier.

The yellow lashing strap attached to the transmission is used for transport and installation safety and may not be removed under any circumstances prior to assembly of the EMO.

The supporting frame has a maximum of nine individual parts, depending on the series.

It is not possible to confuse the components when the supporting frame is assembled. Each bolt connection has an individual bolt pattern which rules out confusion. In addition, only one type of bolt is required for assembly.

A well-coordinated assembly team consisting of three fitters requires approximately thirty minutes for final assembly of the supporting frame.

Through delivery in individual parts, we obtain a substantially higher storage density, as well as much easier loading and unloading of the trucks.

Stress between the supporting frame and the frame members is prevented through adjustment of the central pipe by specialized DEGER staff. Thus the EMO is eased and the longevity of the components clearly increased.

Through the greater elevation angle range of 10°-90° higher yields are obtained at sunrise and sunset.

To assemble the EMO a battery pack with 12 to 26V DC is required. With this battery pack the EMO can be retracted and/or extended as required without a power supply.

Since the greatest forces affect the elevation engine in the storm position it makes sense in structural terms to have the motor retracted when it is in this position.

The MLD control unit as well as the motors are completely pre-wired with delivery. Thus installation times are shortened and installation errors prevented. There are also pre-assembled cable connections for the DC wiring, communication and the cables of all sensors, including wind and snow sensors in the locking plate of the transmission.

As an option DEGER continues to offer an inverter mounting plate with a uniform size for almost any standard inverter available on the market. This inverter mounting plate is installed directly onto the transmission just as before.

We achieve ideal power distribution through a geometry that is unique on the market. Thus the load on bearings, motors and transmissions is eased and the longevity of the complete system clearly enhanced. In addition, the combination of a transmission and frame member saves on both costs and raw materials. Dry bearings from high-performance plastics are used in order to store the moveable parts.

The ‘D’ stands for ‘dual’; that is, dual-axis tracking, while systems that are suitable for installation in regions with increased wind loads are designated with ‘H’, i.e. ‘heavy duty.’ The numerical component of the designation provides an approximate value for possibly installed PV output as a function of the modules employed.

The maximum permissible wind load of the individual systems has not changed with introduction of the DEGER D60H, D80 and D100 trackers.

The maximum permissible module surface of the individual systems has not changed with introduction of the DEGER D60H, D80 and D100 trackers.

With the introduction of the new DEGER D60H, D80 and D100 trackers, the DEGER planning tool for calculating the maximum permissible module surface was updated as well. Thus for error-free planning it is absolutely necessary that the DEGER planning tool V-5.2. be used from now on.
