What does an industrial project contractor look for?
5+1 crucial technical aspects – and what most people forget

The world of industrial contractors is not decided in PowerPoint. Whether you’re talking about a systems integrator, EPC player or a ‘design-supply-install’ type of installer, the real question is: who is the supplier you can really rely on?

At REFU, we work with contractors on a daily basis – so we know exactly what really matters and what is only important in marketing materials.

The system works well if the foundation is stable.

1. Compatibility: on paper vs in reality

It is not only a question of whether a component is compatible “in principle”, but also whether it really works in the given environment, and how much more development and fitting is needed. At REFU, we only recommend components that we know well in different systems. Most of the time is not spent on implementation, but on fitting problems.

2. Documentation: either helps – or hinders

The quality of the documentation also determines the real time, failure rate and profitability of the project. REFU provides structured documentation written by an engineer, not marketing material. This includes 3D models, technical drawings, installation instructions.

3. Warranty and traceability: not an extra, but a basic

Industrial systems operate on a multi-year cycle. That’s why we offer a minimum 10-year warranty. If a device is not available after 6 years – that’s a problem. This does not happen with us.

4. Scalability = strategic reserve

A system is never as big as it was at the beginning. REFU’s robust products, such as our 350 kW inverter, already take the future needs of the project into account. If there’s no scaling margin, the project will be squeezed.

5. Data security: if you network it, protect it

More and more industrial systems are connected to the network – increasing the attack surface. REFU’s communication solutions use certified security protocols and offer real protection. Not just green LEDs.

+1. Communication and attitude – the real difference

Often the technology is good – but the partner is not available. REFU provides technically competent support in Hungarian. We don’t mince words – if something will work, we’ll tell you and show you.

With its robust performance and scalable architecture, the REFU 350K-8T inverter is the ideal choice for industrial solar systems – not just today, but 5 years from now.

Conclusion – if you think like a technical decision-maker, you need a partner

You want not just a good product, but predictable collaboration, honest communication and technical competence. That’s what we believe in. That’s REFU.
