About the role

As a Trainer DC - Elektro, you create training materials, manuals, and digital learning content for DC electrical engineering, covering PV strings, inverters, and battery storage. You conduct theoretical and practical training for internal installers and partner companies across Germany. You also ensure quality through construction site visits and follow-up training, and use field feedback to continuously improve training content.

A typical day

A typical day might involve preparing digital training content or updating manuals from your remote office, then delivering a practical training session to installers at a partner site. You could also visit a construction site to observe installation quality and provide immediate coaching, then document feedback to improve future training. Travel across Germany is a regular part of the role.

Who 1KOMMA5° is looking for

• Has hands-on experience with DC electrical systems in photovoltaic, battery storage, or inverter installations.
• Is comfortable training adults in both classroom and on-site settings, and can explain technical content clearly.
• Is willing to travel nationwide to conduct training and site visits, and can work remotely when not traveling.
• Has experience creating training documents, manuals, or digital learning content for technical audiences.

Tips for this application

• Highlight specific DC electrical projects you have worked on, such as PV string sizing, inverter commissioning, or battery storage installation.
• Describe any training or mentoring you have done, including the size and type of audience (e.g., apprentices, partner companies, internal teams).
• Mention your willingness and ability to travel nationwide for training and site visits, as the role is remote but requires field presence.
• If you have experience with digital learning tools or creating training manuals, provide concrete examples of content you developed.
• Reference 1KOMMA5°'s Heartbeat platform and virtual power plant concept in your application to show you understand their core product.

What to cover in your cover letter

['Your practical experience with DC electrical systems in renewable energy, especially PV, inverters, and battery storage.', 'Your ability to design and deliver effective training for both internal staff and external partners, in theory and practice.', 'Your approach to quality assurance through site visits and follow-up training, and how you use feedback to improve training.', 'Your motivation to work for a company building a virtual power plant and one-stop shop for carbon-neutral energy solutions.']

Research before applying

• Study 1KOMMA5°'s Heartbeat platform and how it connects PV, storage, heat pumps, and charging stations into a virtual power plant.
• Look up the company's one-stop shop model for energy system installation and what partner companies they work with.
• Understand the basics of DC electrical systems in renewable energy, including PV string design, inverter types, and battery storage safety.
• Check if 1KOMMA5° has published any training materials, technical blogs, or documentation about their installation standards.

Likely interview topics

Based on the job description, expect questions about:

• How would you structure a training program for DC electrical systems covering PV strings, inverters, and battery storage?
• Describe a time you had to train someone who struggled with a technical concept. How did you handle it?
• What steps do you take to ensure that training standards are actually applied on construction sites?
• How do you incorporate feedback from the field into updating training materials?
• What do you know about 1KOMMA5°'s Heartbeat software and virtual power plant, and how would you explain it to a partner installer?

Common mistakes to avoid

• Focusing only on theoretical knowledge without showing hands-on DC electrical experience.
• Ignoring the travel requirement or implying you are unwilling to visit construction sites nationwide.
• Submitting a generic application that does not mention 1KOMMA5°'s specific products or the Heartbeat platform.
