GP-2S Ground Screw Post Aluminium Ground Solar Mounting System
GP-2S Ground Screw Mounting system is designed to provide an economical and practical mounting solution for large-scale open areas. Suitable for both framed and unframed modules. Compatible with hydraulic pile driving ram making installations on the open area easy.
Please read the guidebook carefully before the installation.
2. Installation tools and equipment
4.1 Install ground screw foundations
Please prepare all the needed installation tools and related products before the installation.
Mark the positions of all the ground screws according to measurements L1 & L2 on the drawing. Install the ground screw with a screwdriver and leave 200mm height to the ground. Please make sure that all ground screws be aligned horizontally and vertically. Then fix the leg bases on flange-type ground screws with M12 x 40 bolts, nuts, large flat washers, and spring washers. (The horizontal adjustable range of the leg base is 0~60mm and the vertical adjustable range is 0~40mm)
4.2. Install the pre-assembled support racks and triangle-fixing components
4.2.1. Stretch the preassembled support racks, fix the front/rear legs and the movable ends of the support rack on leg bases with M10x80 bolts, M10 flange nuts, and corrugated gaskets.
4.2.2. Fix the rest support rack kits respectively according to the principle in 4.2.1. Adjust the rack kit according to the drawing. Make sure the height of all the support rack kits reaches complete unity and the rails can be fixed on a flat surface.
4.2.3. Connect the triangle fixing components with rear legs according to drawing, fix it with M8×80 bolts, nuts, flat washers and spring washers.
4.3 Install the rails
4.3.1. Install the rails
(Connect the rails with rail splice if the rails are not long enough, otherwise skip this step)
Insert the rail splice half into rail A and then fix it with 2 self-tapping screws on each side.
Insert the other half of the rail splice into rail B, match it together, and then fix it with 2 self-tapping screws on each side as well.
Then the A and B rails are connected.
4.3.2. Fix the rail onto the support rack with fixing clamps (1 clamp on each side).
4.3.3 Fix the rest rails by the above steps according to measurement L3 on the drawing (L3 equals the half length of the panel). Make sure that all the bolts have been tightened up.
Suggest starting the panel installation from the left side of the bottom, and fixing them by end clamp and mid clamp. (Each mid clamp assembled with one piece grounding washer)
5. Installation Notes
5.1. Notes for dimensions
All the dimensions should be subject to the construction drawing. This guidebook is for the descriptive purpose of installation only.
5.2. Notes for stainless steel fasteners
Stainless steel material is quite different from carbon steel with its excellent ductility. It would be unable to unscrew the bolt and nut after matching in case of improper use. That is “lock up”, known as “deadlock”. Methods to avoid lock up as below:
5.2.1. Reduce the friction coefficient
- Make sure the surface of threads to be clean (without dust or clutters);
- Suggest to apply water wax or lubricant on the surface for installation (such as butter or 40# machine oil)
5.2.2. Use the correct operation method
- The bolt must be perpendicular to the axis of the thread when screwing. Do not lean the bolt;
- Apply the force evenly when tightening and the tightening torque should not exceed the specified secure torque value;
- Use torque wrench or socket spanner as far as possible, avoid using monkey wrench or electric wrench; Adjust the rotational speed as low as possible when using an electric wrench;
- Avoid high temperature; To avoid lock up which is caused by sharply increasing temperature, do not rotate rapidly. (like using an electric wrench)
