SOLSOL certified as Pixii Tier 3 Service Partner: faster commissioning, reliable service and tailor-made solutions for C&I projects

Why Service Competence Is Critical

In commercial and industrial (C&I) installations, it’s long been about more than just the technology price. The satisfaction of the end investor and the project’s payback economics also depend on:

• the speed of response in case of a fault or system adjustment,
• the availability of spare parts and the complexity of repairs,
• the ability to expand the system over time as needs change.

 

That’s why strong service capabilities are just as important as the hardware itself. And this is exactly where SOLSOL is now significantly stronger – we’ve achieved the highest level of service certification as a Pixii Tier 3 Service Partner.

What the Pixii Tier 3 Service Partner Certification Means

Obtaining the Pixii Tier 3 Service Partner certification confirms that our team:

• has completed advanced technical and hands-on training directly with the manufacturer
• has the competence to perform full commissioning of Pixii systems,
• can handle complex service interventions without involving external foreign technicians,
• has already successfully delivered and commissioned a large number of Pixii systems.

 

For our clients, this means that all key steps – from system design and engineering, through commissioning, to long-term service – are handled completely in-house.

Faster Commissioning Without Waiting for Foreign Technicians

One of the biggest practical benefits is the shorter time from installation to full operation.

 

Thanks to our Tier 3 certification we can:

• perform commissioning directly with our own team,
• minimise delays caused by waiting for foreign technicians to be available,
• respond flexibly to changes on site or in the project
• accelerate the transition from the installation phase to the phase of generating real savings.

 

The result is a faster project start and an earlier beginning of the economic payback for the investor.

Speed Matters

For projects where BESS provides grid balancing and ancillary services (e.g. FCR, aFRR, etc.), every outage is directly linked to a specific financial loss – the system is not generating revenue from these services, and the investor is also exposed to potential penalties for not meeting contracted performance parameters.

That’s why a key metric is Operational Availability (Ao) – the real operational availability of the system. It’s not just about theoretical technical reliability, but about actual operating conditions, including:

• failures,
• diagnostics,
• repairs and service interventions,
• waiting times for spare parts,
• and any operational limitations.

 

In this area, Pixii is among the manufacturers with one of the highest Ao values on the market. Combined with our Tier 3 service support, investors get a solution that maximises the real availability of the system for grid balancing services – and thus the stability of project revenues.

Direct Service Support and Fast SLA Response Times

In C&I projects, long-term operation is crucial. With our certification and experienced team, we offer:

• a direct service line without lengthy handovers between multiple suppliers,
• guaranteed response times within contractual SLAs,
• efficient diagnostics and fault resolution,
• spare parts availability thanks to Pixii’s standardised components.

 

All of this significantly reduces downtime risk and increases the reliability of the entire system – which benefits both EPC partners and end investors.

Scalability and the Ability to Increase Capacity Over Time

Pixii’s solution is designed to grow with the client’s needs.

Thanks to its modular architecture and our Tier 3 competences, we can:

• design the system to account for future expansion from the start,
• increase capacity over time without having to completely rebuild the installation,
• optimise the configuration as consumption patterns, renewable generation or energy price structures evolve.
•  

Investors thus gain a flexible solution that can adapt to future changes – not just to today’s situation.

A Unique Position in Central Europe

The combination of:

• Pixii’s cutting-edge technology,
• the highest Tier 3 service level,
• and a local team with strong hands-on experience

is still exceptional within Central Europe.

 

This makes it a unique blend of top-tier technology and deep service competence, well suited to the regulatory environment and typical operational scenarios of the region.

SOLSOL: More Than a Hardware Supplier – a Real Partner

At SOLSOL, we’ve always built on the idea that we don’t just sell hardware. Our goal is to:

• be a partner already in the design and sizing phase of the system,
• take part in the complete commissioning,
• and stay by the client’s side for years in the form of long-term service and operational support.

 

We have a specialised team that understands both the technology and the real needs of the C&I segment. With the Pixii Tier 3 Service Partner certification, we can deliver this added value to both our existing partners and new projects.

What This Means for Investors and Partners

For EPC companies, developers and end investors, it all comes down to three key points:

1. Certainty – a reliable solution with long-term local service

2. Speed – fast commissioning and short response times for support.

3. Flexibility – the ability to grow and adapt the system to future needs.
