Installation Consideration and Environmental Conditions
Install SolarEdge modules at sites that meet the following requirements:
l
Environment temperature: -40 to 85 °C
l
Operating temperature: -40 to 85 °C
l
Maximum altitude the module is designed for : 2000 m
l
Mechanical load on modules (e.g., from wind or snow): front design load is less than 3600Pa and rear test load is less than 2400Pa (safety factor of 1.5).
l
To maintain the modules’ Class C fire rating, the fire class of the roof and building materials should higher than Class C. The fire safety rating of this module is
valid only when mounted in the manner specified in the mechanical mounting instructions.
l
Do not install modules at locations that come with direct contact of water, salt water or any aggressive environmental condition.
l
Do not install the modules near flames or flammable materials or locations with hazardous materials.
Installation Methods
Clamping
Modules can be laid either across the supporting rails (
Figure 1
) or parallel to them (
Chapter 2
and
Figure 2
).
Figure 1: Clumping modules onto the frame with aluminum clamps across the supporting rails
Figure 2: Clumping modules onto the frame with aluminum clamps parallel to the supporting rails
Each aluminum mounting clamp comes with an M8 bolt, a plain washer, a spring washer, and an M8 nut.
NOTE
Make sure to use clamps with the following properties:
The dimensions for the middle clamps are a ≥ 40 mm, b ≥ 26 mm, c = 8 mm, d ≥ 28 mm, and Ø = 9 mm.
The recommended torque for tightening the nut and bolts is 28 N*M when the property class of bolts and nuts is Class 8.8.
To fasten the module:
1. Place the module on the two supporting rails (not provided). The rails should be made with stainless material or treated with an anti-corrosion process
(e.g., anodic oxidation treatment).
2. The rail ’s top surface contacted with module frame should come with grooves compatible with an M8 bolt.
3. If the rails do not come with grooves, holes of a suitable diameter may need to be drilled to allow bolts to be attached to the rails at the same locations as
mentioned before.
4. Secure each clamp by attaching plain washer, spring washer, and nut, in that order.
5. Both of close-ups of
