Description:

System solutions with SC/SCS inverters are used in storage power plants and PV plants worldwide. They ensure the stability of transmission lines and reduce energy costs through the use of photovoltaic energy. In order to ensure the maximum efficiency and reliability of your inverter it needs to be maintained on a regular basis. This training empowers you to autonomously conduct this maintenance work in accordance with the SMA maintenance protocol, as well as effectively localize causes for loss of production and downtime. Furthermore, this training enables you to autonomously replace wear and tear parts preventatively and correctively in accordance with the SMA maintenance protocol. That way a maximum of uptime and yield of your inverter will be ensured.

Target group:

SMA customers with electrical knowledge

Mandatory Prerequisites:

• Employee of an existing SMA customer working with SMA inverters on-site (serial-no. of inverter has to be stated during the booking process)
• Self-declaration stating that the participants of the course are qualified electricians, who are aware of the potential risks associated with electricity (as part of the online registration process)
• Participants must wear safety shoes and flame-resistant clothing

Contents:

• Review of Electrical Safety to safely approach the inverter and minimize the risk of exposure to electric shock and arc flash
• Live-demonstration on inverter components and functionality of DC, AC Auxiliary Power, Cooling, Communication, Data Logging and Monitoring
• Exercises on real inverter how to perform preventive maintenance to maximize the system uptime and retain the SMA warranty
• Learn and practice how to read circuit diagrams, finding components and part numbers
• Hands-on exercises on identifying faults caused by the grid, PV array/ battery or inverter components
• Practice how to evaluate event and error codes in order to find the best solution
• Extensive hands-on exercises on component replacement
• Component Replacement List

After this training you* will be able and qualified to:

• Conduct preventative maintenance work in accordance with the SMA maintenance protocol (relevant for retaining SMA warranty)

• Effectively localize causes for loss of production and downtime, as well as find solutions to remedy these causes either on your own or with the help of SMA

• Maximize your efficiency in communicating with the SMA Service line and therefore help potential issues being solved faster

• Conduct advanced corrective and preventative component replacement yourself (as stated in your service contract) on components like power stacks, interior fans, GFDI breaker or 24Vdc power supply

*please note that the certificate documenting your qualification is both bound to the attendee and the company the attendee is working for during the time of enrolling for the training course (i.e. the certification is nullified if the attendee changes the company afterwards). The certificate is valid for 5 years after completion of the training and then must be renewed via an online refresher training.

After this training you will not be qualified to:

• Conduct maintenance work on any other inverter type than the model line covered in your training

• Train other employees of your company on corrective and preventative maintenance of SC/SCS inverters

• Commission SMA inverters on your own (this service is offered by SMA specialists only)
