LKH Leoni Solar Power Plant in Hatvan
490 kW ground-mounted photovoltaic system
Leoni cable manufacturing facility in Hatvan operates continuously. Due to load requirements, the photovoltaic system is connected to two transformer zones. Metering is carried out on the medium-voltage side, and telemechanical systems are also implemented. The system consists of 4 × 100 kW, 1 × 50 kW, and 2 × 20 kW Huawei inverters, a DAV mounting structure, and 1,000 Longi 615 W photovoltaic modules.
The project included 2 road crossings (horizontal drilling) and a 220-meter AC cable route between the AC combiner cabinet and the transformer. Modifications were required on the 0.4 kV side of the transformer due to busbar arrangements. Commissioned on March 18, 2026, by the DSO.
