1. Introduction
Clenergy PV-ezRack® SolarTerrace II-A™ is a pre-assembled ground mount system suitable for
large scale commercial and utility scale installations. PV-ezRack SolarTerrace II-A has been
developed to fit any PV module. The innovative and patented SolarTerrace II-A T-Rails simplify and
improve the accuracy of the installation. SolarTerrace II-A uses high quality engineered
components, saving developers and installers time and money when delivering ground mount
projects.
Please review this instruction guide thoroughly before installing PV-ezRack SolarTerrace II-A. This
manual provides the supporting documentation for building permit applications relating to PV-
ezRack SolarTerrace II-A Universal PV Mounting System.
The PV-ezRack SolarTerrace II-A components, when installed in accordance with this guide, will be
structurally adequate and will meet the AS/NZS1170.2:2011 Amdt. 3-2012 standard. During
installation and especially when working on the ground, you will need to comply with the
appropriate occupational health and safety regulations. Please also check other regulations
relevant to your local region. Make sure that you are using the latest version of the installation
instruction guide, which you can do by contacting Clenergy by email on [e-mail], or
contacting your local distributor.
The installer is solely responsible for:
Complying with all applicable local or national building codes, including any that may supersede
this manual;
Ensuring that ezRack and other products are appropriate for the particular installation and the
installation environment;
Using only ezRack parts and installer-supplied parts as specified by ezRack (substitution of
parts may void the warranty and invalidate the letter of certification);
Ensuring that the ground condition are suitable;
How to recycle: according to the local relative statute.
How to disassemble: reverse installation process.
Ensure that there are no less than two professionals working on the panel installation.
Ensure the installation of the electrical equipment is performed by a professional and accredited
electrician.
Ensuring safe installation of all electrical aspects of the PV array, including providing adequate
earth bonding of the PV array and PV-ezRack® SolarTerrace II-A™ components as required in
AS/NZS 5033-2014 ADMT 2 2-2018.

3.2 Installation Spacing
Max Frame Spacing and Footing Options of Panel Dimensions 1.7m x 1m

Clenergy Australia | 1/10 Duerdin St, Clayton VIC 3168 | T: [phone] | [email protected] Page 8 of 18
Max Frame Spacing and Footing Options of Panel Dimensions 2m x 1m
Notes
*The maximum frame spacing is based on the structural capacity of the frame in the edge (perimeter
zone of array. We recommend to perform tests on site for the geotechnical capacity of the driven post.
The spacing may need to be decreased to achieve the available geotechnical capacity of the driven
post following from the test results.
**Footing option 2 recommended for 'Firm' soils with allowable end bearing capacity of 100 kPa (damp
clays, sandy clays, damp sands). Other piers sizes are possible. Contact Clenergy for site specific
conditions.
*For SolarTerrace II-A driven post installation, maximum post height above ground is 1.3m.
*For SolarTerrace II-A concrete pier installation, maximum post height above ground 1.5m.

4. Installation instructions
1． C-Post installation
1a. Before starting, check you have
the installation tools needed.
Position the required components
close to the installation location.
Make sure that the hydraulic pile
driver equipment is suitable for your
particular installation.
Mark the line of the post array.
1b. Obtain the maximum allowed
distance between posts and the
minimum embedment length from
the relevant engineering certificate
and/or project drawing. If you don’t
have this document, please contact
the Clenergy customer service.
Mark the positions of the posts (you
can use a string and a tape
measure or a GPS) and drive the
posts into the ground. Make sure all
posts are in line and set to the
correct height according to the
drawing (you can use a sting or a
laser tool).
Note: apply zinc coating to upper
section (circled) of C-Post after
piling. The reason for that is that
ramming can damage the
galvanisation of the posts.
2． Post head installation
Install the post head and fix it with
the two M12 bolts and nuts
supplied. To avoid stainless steel
galling/seizing apply grease or
lubricant if needed.
Recommended torques:
Bolt 1: 55 Nm
Bolt 2: 23 Nm
