SolarEdge P370-5RM4MRM Power Optimizer 370W 5–60V 15A for Photovoltaic Systems

The SolarEdge P370-5RM4MRM is a photovoltaic power optimizer designed to maximize the energy output of individual solar modules through advanced module-level MPPT (Maximum Power Point Tracking) technology. By continuously optimizing the operating point of each panel, the P370 minimizes energy losses caused by partial shading, dirt accumulation, module mismatch, aging, and varying environmental conditions. This allows each module to perform independently, improving the overall efficiency and energy yield of the photovoltaic system. Designed for use with compatible SolarEdge inverters, the optimizer also enables advanced module-level monitoring, providing detailed performance data for each connected solar panel. The unit features integrated photovoltaic connectors and a built-in mounting bracket for fast and reliable installation. ⚙️ Technical Specifications Identification Data Manufacturer: SolarEdge Model: P370-5RM4MRM Identification Code: NA30SZ2520-0209489AD-EA Product Type: Photovoltaic Power Optimizer Technology: Module-Level MPPT Application: SolarEdge Photovoltaic Systems Input (DC) Input Voltage Range: 8 – 60 VDC Maximum Input Current: 11 A Open Circuit Voltage: 1 V Output (DC) Rated Output Power: 370 W Output Voltage Range: 5 – 60 VDC Maximum Continuous Output Current: 15 A System Specifications Maximum System Voltage: 1000 VDC Integrated Photovoltaic Connectors Built-in Mounting Bracket Outdoor Installation Suitable 🔧 Main Features ✔ Module-level MPPT optimization ✔ Increased photovoltaic system energy production ✔ Reduced losses caused by partial shading ✔ Compensation for module mismatch and performance differences ✔ Advanced panel-level monitoring ✔ Compatible with SolarEdge inverter systems ✔ Fast installation with integrated cabling ✔ Improved system design flexibility ✔ Enhanced DC-side safety and performance management 🔌 Purpose and Operation The SolarEdge P370 continuously tracks the maximum power point of the connected photovoltaic module, ensuring that each panel operates at its highest possible efficiency.
