Inverters are a core component of PV plants. Ongoing development turns simple power and voltage transformers into complex data and energy interfaces in the context of a Smart Home, which feature:

  • Monitoring-,
  • Control-
  • Storage functions

Perfectly working inverters form the basis for high solar gains and security of supply. If there is component damage or damage due to external impact, such as a fire or a power surge after a lightning strike, the inverters can be professionally checked and repaired at the ADLER Solar Test and Repair Centre, which is especially equipped for this purpose.

Short handling times or the provision of a replacement minimise loss of revenue and thus your financial damage. Our customers include insurance companies, banks, institutional investors as well as plant operators.

ADLER Solar offers a complete set of solutions from one provider for inverters:

  • Checking faults
  • Analysing causes
  • Repairing string inverters (at the Test Centre and on site)
  • Refurbishing
  • Supplying replacement devices

Meet us next week in Munich. ADLER Solar appears together with Europe Solar Concept, Solar Fabrik and pvXchange at this year’s Intersolar

Intersolar is one of the most important trade fairs globally for the solar industry. These PV experts present their complementary product and service portfolios at the joint booth 450 in Hall B3:

  • Europe Solar Concept – Europe-wide system wholesaler for photovoltaic components
  • Solar Fabrik – German module manufacturer who re-entered the market
  • pvXchange – international trading platform for PV modules and components
  • ADLER Solar – leading full-service provider for the solar industry

ADLER Solar delivers a broad spectrum of technical solutions and services that guarantee a high performance level and smooth running of a photovoltaic plant throughout its entire life-cycle. For its customers, the PV expert develops customised solutions “Made in Germany” at its Services and Solutions competence centres. In addition, key topics like battery storage, performance optimisation, claim management and inverters are presented at the trade fair.

Europe Solar Concept informs attendees about its modules, inverters, storage systems, rack technology, monitoring systems and all accessories that are required to install photovoltaic plants. The fair exhibits are explained by specialised ESC personnel and fair attendees are advised in depth.

Since last year, ADLER Solar and Europe Solar Concept have already offered a jointly optimised solution for junction boxes that were affected by the former Solar-Fabrik AG’s product warning.

Solar Fabrik manufactures PV modules with long-time experience, new impulses and innovative new developments. These are a guarantee for highest profitability and optimum return on investment. State-of-the-art technology ensures continued module production at the German location.

pvXchange has established itself throughout the industry as an international marketplace for photovoltaic components in the B2B market. In addition to selling economically priced new products, a unique selling point of the company is the provision of replacement modules and inverters for existing plants. Almost all replacement module requests can be served from its warehouse, which houses more than 1,000 different types and performance categories.

Drop by or make an appointment in advance – we cordially welcome you in Hall B3 at booth 450.

ADLER Solar in Japan:
PV Training Center with reference plant in Yokohama opened

With a formal ceremony ADLER Solar opened their new PV Training Center including a PV reference plant in Yokohama, Japan, on May 30th. Last year, this leading full service provider for the solar industry was awarded a contract by the dena (Deutsche Energie-Agentur German Energy Agency) to install a PV plant as part of a PV Training Center in Japan within the scope of the dena Renewable Energy Solutions Programme.

The opening ceremony was attended by a number of high-ranking officials, i.e. Dr. Hans Carl von Werthern, German Ambassador in Japan, and Yutaka Matsuzawa, Division Manager of Climate Change Policy Division, Global Environment Bureau, Ministry of the Environment.
The goal of the new PV Training Center is to pass on the many years of experience and expertise “made in Germany” to the Japanese market. At the same time, the ADLER Solar Works joint venture founded last year with the Japanese general contractor Yokohama Kankyo Design (YKD) in Yokohama is further establishing itself on the target market of Japan.

Targeted training of customers, employees, and partner companies
The Training Center enables ADLER Solar to provide training and further education for existing and new employees of ADLER Solar Works in the best possible way. Thanks to precisely developed training modules, the high service quality and competence of the ADLER Solar Works partner companies is also being ensured. What is more, customers are given an opportunity to become acquainted with the service portfolio of ADLER Solar Works on site.

The PV plant installed especially for training purposes guarantees an extremely practical knowledge transfer and – in conjunction with the teaching of the relevant theoretical content – makes the high quality and sustainable development of the measure possible. The plant was completed together with select technology partners and has various module technologies as well as a scientific weather station and an extended monitoring system. Within the scope of the Training Center, existing services for the Japanese market are also to be optimised or even redeveloped.

“We are pleased to be allowed to contribute our industry competence and many years of expertise to such an exciting project with such renowned partners. The experience we have gained on the German and European market is being incorporated here at a 1:1 ratio, and this means that we can transfer best practice methods to Japan,” says Gerhard Cunze, Managing Director of ADLER Solar.

This project is part of the worldwide dena Renewable Energy Solutions Programme coordinated by Deutsche Energie-Agentur (dena) – the German Energy Agency – and co-financed by the German Federal Ministry for Economic Affairs and Energy (BMWi) within the German Energy Solutions Initiative (
