This document is about the maintenance manual of the VANGUARD series solar tracker
The document serves as a standard maintenance guide for the Vanguard TT-V2P tracker system. It outlines a schedule of preventive maintenance tasks to be performed annually, including the verification of torque tightening values, inspection of electrical connections, and checking operational parameters like tilt angles and wind signals.
Specific procedures are detailed for inspecting structural elements such as piles heads, galvanization, plastic bearings, and linear actuators. The manual also addresses battery preservation modes based on energy levels and temperature-dependent operation limits to ensure system longevity.
| Torque tolerance (Rigid joints) | ±1 0% respect Assembly Manual value |
|---|---|
| Torque tolerance (Contactless joints) | +0/ -10% respect Assembly Manual value |
| Tilt angle tolerance (TCU SS) | ±1 degree |
| Tilt angle tolerance (TCU SP) | ±1.256 degrees |
The verification of a correct torque tightening value for tracker bolts must be performed on an annual basis.
Rusted areas must be repaired immediately by eliminating rust particles and applying zinc-rich paint to protect the surface.
Plastic bearings must be inspected annually for cracks, excessive wear, or misalignment in their components that allow rotation.
