Strong growth in utility-scale systems, but grid bottlenecks, complex requirements and high time pressure are challenging EPCs and project developers. Innovative, standard-compliant connection technology from enwitec is becoming a decisive success factor.
- Utility-scale PV is becoming the strongest growth driver in the solar industry
- Grid bottlenecks and increasing standard requirements increase the complexity of large PV projects
- SolarConnect 1500 and FieldConnect support EPCs with grid integration and connection technology
- enwitec combines high-performance system solutions with engineering and certification support
The European solar industry will undergo a clear structural shift in 2025/2026. While the residential and smaller C&I sector is under pressure, the utility-scale sector is driving growth. According to SolarPower Europe, the share of large-scale ground-mounted and utility systems will exceed 50% of new installations for the first time. Utility-scale capacity is set to more than double by 2030 – driven by auctions, corporate PPAs and merchant projects.
At the same time, the challenges are intensifying massively: grid bottlenecks threaten over 120 GW of planned renewable energy projects across Europe, long connection queues, increasing requirements for monitoring, overvoltage protection, string monitoring and strict standards such as DIN EN 61439, VDE-AR-N 4110 and VDE-AR-N 4120. Errors in the DC and AC connection technology quickly lead to expensive rework, delays in commissioning or even failure of the grid connection approval.
This is where enwitec electronic GmbH, part of the greenLink Group, comes in with high-performance system solutions and a holistic EPC approach.
SolarConnect 1500: The high-performance GAK for 1500-volt utility projects
The newly developed SolarConnect 1500 has been specially designed for large ground-mounted PV systems with central inverters. The SolarConnect 1500 can also be used cost-effectively for large rooftop systems. With system voltages of up to 1,500 V DC, connection options for up to 24 strings and comprehensive string current monitoring via MOD-BUS, it sets new standards in efficiency and operational reliability.
Technical highlights:
- Precise string current, voltage and temperature monitoring with MOD-BUS interface for real-time diagnostics and maximized yields
- Remote-controlled load-break switches (manual or motorized, up to 630 A)
- Integrated surge protection (type 1/2 or type 2) in accordance with current lightning protection guidelines
- Robust GRP-reinforced polyester housing, protection class up to IP65, protection class II
- Mounting options: Wall mounting, rack mounting
- Standard-compliant design in accordance with EN 61439-1/-2 and taking into account the requirements of DIN VDE 0100-712 and HD 60364-7-712
Thanks to pre-assembled, project-specific versions (e.g. with MC4 connectors, Al/Cu terminals or line monitoring), EPCs significantly reduce planning risks and installation times.
FieldConnect 400 & 800: Powerful AC distribution for large parks
The FieldConnect 400 & 800 series is the perfect addition on the AC side. These AC distributors are designed for system voltages of 400 V & 800 V and are characterized by their high load capacity, modular design and integrated overvoltage protection.
Strengths:
- Busbar systems (5-pole) with high-quality NH switch-disconnectors
- Suitable for indoor and outdoor use (glass fiber reinforced polyester, IP65)
- Minimized wiring effort and simple integration of measuring and protective devices
- Project-specific adaptations for individual grid connection conditions
enwitec as a strategic EPC partner: complete solution from a single source
What makes enwitec particularly valuable for EPCs goes far beyond individual products. As a system partner for engineering, procurement and construction, enwitec supports utility projects from 1 MW upwards from the initial planning stage through to successful grid-on.
Concrete advantages:
- One central point of contact – significant reduction in interface risks
- Needs analysis & consulting in close coordination with network operators
- Custom engineering with EPLAN circuit diagrams, precisely matched to the inverter and park layout
- Precision manufacturing “Made in Germany” with 100% final inspection
- Certification & documentation support for the system certificate in accordance with VDE-AR-N 4110/4120
- Commissioning support and long-term after-sales service
In addition, enwitec supplies the complete protection and control technology: PowerShield 500 / Pro 1100 (grid and system protection), PowerControl 500 (certified EZA controller with telecontrol technology and direct marketing) as well as grid switching and backup solutions.
Conclusion: More safety, less risk, faster commissioning
In a market environment with grid bottlenecks, increasing quality requirements and high time pressure, reliable and standard-compliant connection technology is increasingly becoming a success factor for utility-scale PV projects.
The combination of powerful system solutions such as SolarConnect 1500 and FieldConnect as well as comprehensive engineering and certification support helps EPCs to reduce risks, simplify processes and implement projects efficiently.
