Project of a 30 kW grid-tied solar power plant in Khmelnytskyi for self-consumption by a private house. Modern components and an integrated approach ensure the system’s long-term and stable operation. For this project, 63 UL-610M-132DDGN solar panels and a Solis S5-GC30K three-phase grid-tie inverter were used. The system was built to provide the house with electricity and to save on electricity.
