Frecon PV500-4T-7.5B-H 7.5kW VOC800/MPPT450-600 Solar input 380V 3Ph output
Features
The Frecon PV500‑4T‑7.5B‑H 7.5kW VOC800/MPPT450‑600 Solar input 380V 3Ph output inverter is engineered for high‑performance pumping applications, delivering robust compatibility with multiple motor types including AM, PMSM, BLDC, and more. With up to 99% energy conversion efficiency, it reduces operating costs while maximizing water output, making it the ideal solution for agricultural, industrial, and rural water supply systems where reliability is critical.
Designed for flexibility, the inverter supports both solar DC input and grid AC input, featuring an intelligent DC/AC auto‑switching function. During periods of low solar intensity, it automatically enters dormancy mode to conserve energy, resuming seamlessly when sunlight improves. Importantly, it operates without a battery, lowering upfront investment and minimizing maintenance requirements.
Built‑in comprehensive protection functions safeguard against over‑current, over‑voltage, phase loss, short circuit, and over‑temperature. Integrated dry run protection and tank water level control prevent pump damage and optimize water management. Under identical operating conditions, the Frecon PV500‑4T‑7.5B‑H 7.5kW VOC800/MPPT450‑600 Solar input 380V 3Ph output delivers a higher water yield, ensuring improved productivity and efficiency.
Performance tracking enhances system management, recording total power generated (kWh), water flow (m³), and cumulative operation time (hours). Models from 0.4–2.2kW can be configured with a DC boost module, reducing solar panel requirements and lowering system costs. Additionally, all models can be equipped with a GPRS module, enabling real‑time remote monitoring and operation via web platforms.
