REPAIR

Tresun adopts the circular economy model, which represents a sustainable and beneficial solution for the environment, society, and the economy. This replaces the 'produce, use, and dispose' paradigm with a new, more sustainable and efficient approach

Durability - Repairability - Recycling - Resolution

In Europe, there is a discussion about the potential introduction of Eco-Design regulations to compel manufacturers, importers, and distributors of electrical and electronic equipment to design and produce devices that are easily repairable and replaceable, with the aim of establishing a real and effective circular economy

Photovoltaic Inverters

"In medium-sized installations, replacing the inverter park could lead to a decrease of approximately 2% in the Return on Investment (ROI). Malfunctions are often attributed to faults in the DC/AC converters The economically preferable choice may be to repair and/or regenerate non-functioning inverters, thereby increasing the profitability of the investment.

Through the expertise and professionalism of our technical teams, Tresun provides the following services:

  • • Technical Examination and Diagnosis
  • • Fault Detection and Cause Analysis
  • • Replacement of Defective and/or Non-functioning Components
  • • Testing & Commissioning
  • • Pre and Post-Intervention Support (Remote and On-site)

UPS

Uninterruptible Power Supplies (UPS) activate in the event of a power outage, thereby protecting the equipment
It is essential to establish and implement a preventive maintenance plan to avoid power interruptions, which can result in significant costs, reaching hundreds of thousands of euros for business operations. In certain critical sectors such as hospitals, banks, data servers, etc., such interruptions are entirely unacceptable

Proper maintenance can extend the efficiency of such equipment beyond the 20-year lifespan. Our technicians, specialized in the maintenance and repair of all brands, perform specific tasks such as:

  • • Visual mechanical and electrical inspection
  • • Thermographic inspection (Hot Spot Inspection)
  • • Measurement of residual efficiency of the battery body
  • • Analysis and verification of the discharge curve
  • • Calibration of voltage and charging current on the UPS
  • • Verification of integrity/functionality of switches, bypass, etc.

Tresun offers maintenance plans, component-level replacement of UPS on-board electronics, battery body replacement, disposal, testing, and commissioning
