Frecon PV150-4T-0.7B-H 0.75kW VOC800/MPPT450-600 Solar input 380V 3Ph output

Features

The FRECON PV150-4T-0.7B-H 0.75kW is designed for high‑performance pumping applications, offering compatibility with multiple motor types including AM, PMSM, BLDC, and others. Engineered for efficiency and reliability, it achieves up to 99% energy conversion, significantly reducing operating costs while maximizing performance. This makes it an ideal solution for agricultural, industrial, and rural water supply systems where dependable pumping is essential.

The inverter supports both solar DC input and grid AC input, featuring an intelligent DC/AC auto‑switching function. During periods of low sunshine intensity, it automatically enters dormancy mode, conserving energy, and seamlessly resumes operation when solar conditions improve. Importantly, it can operate without a battery, lowering investment costs and minimizing maintenance requirements.

Comprehensive protection functions are built in, including safeguards against over‑current, over‑voltage, phase loss, short circuit, and over‑temperature. Integrated dry run protection and tank water level control further enhance reliability, preventing pump damage while optimizing water management. Under identical operating conditions, the FRECON inverter delivers a higher water yield, ensuring improved productivity and efficiency.

Performance tracking is another key advantage. The inverter records total power generated (kWh), water flow (m³), and cumulative operation time (hours), giving users clear insights into system output. Models ranging from 0.4–2.2kW can be configured with a DC boost module, reducing the number of solar panels required and lowering overall system costs. Additionally, all models can be equipped with a GPRS module, enabling real‑time remote monitoring and operation through web platforms.
