How technical support turns projects into customer success stories

As solar installers expand into batteries and EMS, many find themselves navigating unfamiliar ground. The hardware is new, the integration requirements are more complex and customers expect seamless solutions. For installers, the challenge is about choosing the right technology and finding a partner with the technical expertise to support these projects long after the installation is complete.

Battery storage and EMS integration requires understanding of power electronics, grid interconnection protocols, safety systems and intelligent energy optimization algorithms. The systems must seamlessly coordinate solar generation, battery charging and discharging, load management and grid interactions, all while maintaining safety standards and regulatory compliance. 

For installers, this often raises important questions: What technical expertise do I need? How complex is the installation process? Who will I call if something goes wrong a year from now? 

The answers depend largely on the partner you choose. A strong technology partner should bring technical guidance, training and reliable after-sales support. Without that, installers risk delays, costly troubleshooting and unsatisfied customers.

What to look for in a partner

When evaluating potential battery and EMS partners, consider these qualities:

• Proven technical expertise: Look for teams with hands-on experience designing, integrating and optimizing storage solutions in real-world projects.
• Structured training: Your team should have access to resources and practical training that prepare them for installation and service.
• Clear commissioning support: Step-by-step guidance ensures your projects stay on schedule and reduce risk.
• After-sales service: Systems evolve, customer needs change and issues may arise. A reliable support team is critical for long-term success.
  
  

A real-world example: Van der Spek

The qualities above make the difference between a smooth project and a challenging one. To see what this looks like in practice, consider the example of Van der Spek.

A leading equipment supplier in the Netherlands, Van der Spek faced a familiar challenge for many businesses: how to reduce energy costs and increase sustainability without disrupting operations. 

iwell designed and implemented an integrated solution: a 1.5 MW / 3.4 MWh battery energy storage system controlled by iwell's proprietary EMS. The system connects solar panels, batteries and charging infrastructure into a unified platform that makes optimal energy decisions every minute. Van der Spek now stores solar surpluses for later use, provides smart power distribution to prevent charging queues, participates in grid balancing for additional revenue and maintains charging reliability around the clock.

The technology provided the foundation, but what made this project successful from an installer's perspective was the comprehensive support throughout the process. From initial system design to three months of execution to ongoing 24/7 monitoring and optimization, the installer had access to specialized technical expertise at every stage.

The path forward

The installation business is built on trust, and when you expand into battery storage and energy management, that trust becomes even more critical. Clients are making substantial investments in technologies they may not fully understand, relying on your expertise to guide them toward optimal solutions. When you can explain not only what a system will do, but also how it works, how it's supported and what happens if issues arise, clients feel secure in their investment. When you can demonstrate successful similar projects and provide access to ongoing technical expertise, you're offering true peace of mind.

Battery storage and EMS may be new territory, but with the right partner, it doesn’t have to be uncertain. By prioritizing technical expertise, training and after-sales support in your partnerships, installers can set themselves up for more reliable projects, happier customers and long-term growth.
