The ALPHA SKID 4600 is not just a piece of equipment, but an industrialized approach to large-scale photovoltaic infrastructure—a standardized, scalable, and future-ready solution built to support the accelerated pace of the energy transition and the increasingly complex requirements of utility-scale projects.
Why ALPHA SKID 4600?
The energy transition mandates a new discipline of execution: efficiency, speed, and standardization on an industrial scale. The accelerated development of large-scale photovoltaic projects—in the range of hundreds of MW—is shifting the focus from fragmented solutions to integrated, compact, and prefabricated platforms.
From design to commissioning, our Contracting division ensures the complete delivery of energy projects through integrated EPC (Engineering, Procurement & Construction) services coupled with our own equipment production. The division offers: full design and engineering, procurement and technical logistics, site execution and electrical installation, testing, commissioning and SCADA integration, maintenance services, and post-installation support.

De ce ALPHA SKID 4600?
Advanced Technical Concept, Industrially Validated:
- The outdoor central inverter, with power ratings up to 4600 kVA, performs DC/AC conversion with high efficiency and reactive power control functions
- The ONAN-type transformer (hermetically sealed or with conservator) is optimized for PV applications, maintaining minimal losses and consistent operational performance
- Compact and SF6-Free Medium Voltage Switchgear (RMU)
- The low-voltage panel powers the auxiliary systems: control and monitoring, lighting, ventilation, sensors, and solar trackers
- Cables are specifically designed for resistance to vibrations, humidity, UV radiation, and fire
- The entire assembly is engineered to operate without derating between −40°C and +60°C.
