Our company repairs the electrical parts and electronics of solar inverters.


We carry out: 

- diagnostics and repair of solar inverters with power from 3 kW
- diagnostics and repair of uninterruptible power supplies with power from 10 kW
- diagnostics and repair of ATS (automatic transfer switch) of autonomous power plants
- diagnostics and repair of voltage stabilizers (except those made in China)
- maintenance work on electrical equipment
- diagnostics and repair of electric vehicle chargers

Given the rapid development of the alternative energy sector, there is an urgent need for service maintenance of solar inverters. The solar inverter itself is a fairly complex technological device, the diagnosis and repair of which cannot be done without the involvement of specialized specialists. To work with inverters, you need not just a material and technical base, but also experience and access to the necessary technical information and software.

When the need arises to repair a solar inverter, the question arises, why does it break?

Typically this happens for the following reasons:
- the system as a whole is poorly designed
- low quality of components of the element base
- the resource of the solar inverter has been exhausted
- unauthorized intervention in the design of the solar inverter
- violation of the operating conditions of the device itself (temperature, humidity, etc.)

Who is qualified to repair solar inverters?

As a rule, this is a specialized service center of the company that imports such equipment. Given the narrow specialization, there are only a few such service centers.

Can line voltage affect the performance of a solar inverter?

No, he can not. As a rule, all manufacturers of inverters (including those produced in Asian countries) want to sell their equipment on the European market, and according to the requirements of EU countries, such devices must have double protection in case of deviations from the proper voltage and frequency parameters.

Can lightning damage the inverter?

Surely it can. A lightning strike is a non-standard phenomenon with unpredictable consequences.


Can I repair my solar inverter myself?

In this case, an analogy can be drawn with the electronics of a modern car. Is it possible to repair electronics yourself without the appropriate knowledge, experience or equipment? The question is rhetorical, of course, it’s impossible. Moreover, the inverter is a more specific piece of equipment than a car, the performance of which is affected by the entire system (solar station) as a whole.

Which inverter is better to choose when designing a solar station?

If we talk about manufacturers, then, of course, famous brands will be a priority. But as experience in using complex electronic devices shows, it is most reliable to purchase equipment that has qualified service support in the country-region where the device is used.
