Tamarack Ground Mount System Features
• Designed for mounting photovoltaic (PV) arrays on the ground.
• Top clamps and rail attachments require the use of a single standard 1/2-inch socket
• 5050 Clamp for both mid-clamp and end-clamp use simplies ordering and stocking parts.
• Module clamps are spring loaded to ease module placement.
• Built-in wire management for module and microinverter cables
Tamarack Product Summary
The Tamarack Solar Ground Mount system is a visually appealing photovoltaic (PV) module installation system
that signicantly lowers PV module installation cost by allowing the installation professional to stock fewer
parts and to complete the installation in less time.
Certied to meet local and International Building Codes and ASCE/SEI-7
when installed in accordance with this manual.
ETL Listed to UL 2307 for bonding and grounding when in¬stalled in
accordance with this manual.
Rails, clamps, splices, and mounting devices are UL2703 Listed for
mounting at-plate Photovoltaic Modules and Panels
• Conforms to STD UL 2703 (2015) Standard for Safety First Edition: Mounting Systems, Mounting Devices,
Clamping/Retention Devices, and Ground Lugs for Use with Flat-Plate Photovoltaic Modules and Panels.
• Certied to CSA STD LTR AE-001-2012 Photovoltaic Module Racking Systems.
• Max Overcurrent Protective Device (OCPD) Rating: 20A
• Max Module Size: 25.6 ft²
• System Level Allowable Design Load Rating: meets minimum requirements of the standard (10 PSF down-
ward, 5 PSF upward, 5 PSF lateral). Actual system structural capacity is dened by PE stamped certication
letters.
Tamarack Solar Ground Mounts use Hollaender® structural aluminum pipe ttings that combined with pipe
make stable, secure, corrosion-free mounting rack systems for both ground and roof mounted solar arrays. Hol-
laender’s Speed-Rail® ttings are ideal for this application because the aluminum-magnesium 535 alloy used
to manufacture them is the most corrosion resistant aluminum alloy available. It can be used with steel without
any concern for galvanic corrosion. Hollaender Speed-Rail® ttings are now approved as UL 2703 Recognized
Components under ETL Mark 5006568. The system uses set-screws that penetrate the surface of the pipe to
ensure that ttings are electrically bonded to pipe and bracing, thereby eliminating the need for added bonding
components such as jumpers to provide a grounding path.
This manual describes proper installation procedures and provides necessary standards required for product
reliability. Warranty details are available on our website. www.tamaracksolar.com
All installers must thoroughly read this manual and have a clear understanding of the installation procedures
prior to installation. Failure to follow these guidelines may result in property damage, bodily injury or even
death.

Installer Responsibilities
• Follow all applicable local or national building and re codes, including any that may supersede this manual.
• Electrical installation should be conducted by a licensed and bonded electrician or solar contractor.
• Module maintenance or removal must not break the bonding path of the system.
• Ensure all products used are appropriate for the installation and array under the site’s wind and snow loading
conditions.
• Ensure information is used for the system design is accurate. Any inaccurate information used for the system
design will cause errors and are the installer’s responsibility to correct.
• We recommend consulting with your local building department about local regulations and building require-
ments, including soil conditions, terrain, and wind and snow load requirements. Local conditions and
• Use only Tamarack Solar Products parts or parts approved by Tamarack; substituting parts may void any
applicable warranty.
• Ensure bare copper grounding conductors do not contact aluminum and zinc-plated steel components in order
to prevent the risk of galvanic corrosion.
• The Installation should be inspected periodically, and any loose components or fasteners should be retight-
ened. Any corroded parts found should be examined carefully to assess whether the corrosion compromises the
physical integrity or performance of the system, and if so, the corrosion should be remediated, or the aected
components replaced.
• Provide an appropriate method of direct-to-earth grounding according to the latest edition of the National
Electrical Code, including NEC 250: Grounding and Bonding, NEC 690: Solar Photovoltaic Systems, and CSA
C22.1, Safety Standard for Electrical Installations, Canadian Electrical Code, Part 1
• Disconnect AC power before servicing or removing microinverters and power optimizers.
• Review photovoltaic module manufacturer’s documentation to ensure compatibility and compliance with
warranty terms and conditions.
• Maximum Series Fuse Rating for the photovoltaic array is 20 Amps.
