Pivotal to our company’s portfolio of services, we can diagnose and repair any power generation control system irrespective of age, make, model or function, without the use of manuals or schematics. Our proven track record over more than 15 years affirms our reputation for providing professional protection relay repair, wind turbine repair and refurbishment services to all sectors of the renewable energy industry.

In order to achieve this level of expertise and ensure that every repair has a positive outcome, we have invested heavily in state-of-the-art signature analysis equipment and testing technology. After we have refurbished your equipment, our plug and play solution allows your renewable energy equipment to be re-installed and commissioned into the solar or wind generation farm confidently and reliably. Integral to our overall offering, and one of our secrets to success, is our extensive range of current and superseded spare parts and components, which means we have the discontinued components to ensure your inverter or energy generation can be refurbished back to brand new condition. Rom-Control also has access to a world-wide network of specialist providers for those obsolete and discontinued electronic components that can be very hard to find.

The equipment we can service includes all types of renewable energy power generation, including the high-cost converters and inverters used to supply the AC grid from the DC power generator. The type of equipment is similar; whether it be from solar generation or wind generation, the power supply and other generation monitoring and condition equipment is very similar. We can repair equipment from manufacturers including Vestas, GE, Suzlon, Senvion, Goldwind, Siemens, Delta, Luminous, Xantrex, Microtek, Ellies, APC, ABB and many other brands.

Our Process

Our process consists of the following steps:

1. We will take details photos of the PCB and record the details in our database.
2. We will catalogue the card and apply a barcode label for future identification.
3. We will clean the card using an ultrasonic bath cleaning system.
4. We will identify the fault(s) and replace the faulty components.
5. We will identify any faults (not visible to the naked eye) on the board, tracks, joints and connectors before performing the appropriate repair.
6. We will identify and remove any signs of corrosion.
7. We will proactively replace all other components that we know from experience will most likely fail in the future.
8. We will clean the card again to remove any organic or flux residues.
9. We will bench test the card.
10. As an option, we can apply conformal coating that will protect the card against moisture or dust.

In many ways, the inverters and converters used in renewable power generation can be very complex, which means repairs need to be exact to prevent secondary failures in other systems. High currents and voltages must be considered to ensure the equipment can be placed back into service to provide a safe and reliable outcome. This is the same for solar inverters, wind farm inverters and even battery power inverters. Call us today if you need us to carry out any solar inverter repairs or wind power system repair work.

Often power inverters may fail due to a simple little component varying its output due to age or environmental conditions, causing a cascade effect of many inverter components failing. Although this single component may pass bench tests, if not diagnosed and replaced, re-assembling the inverter or converter and powering up may cause an unsafe and expensive failure. Due to Rom-Control’s broad experience in this area, we can guarantee every inverter fault is located, with components replaced and tests conducted to the renewable industry standard.
