The SolarEdge P950-4RMXMBY is a module-level power optimizer specifically designed for high-power and bifacial photovoltaic modules in large commercial and industrial solar power plants. Thanks to its integrated modular MPPT, it ensures maximum performance even in the event of partial shading or varying panel orientations. The device is designed for full compatibility with SolarEdge SE25K three-phase inverters and higher models.
The P950 optimizer allows up to two photovoltaic modules to be connected in series, providing an output power of up to 950 W. Thanks to its high efficiency (up to 99.5%) and SafeDC™ technology, it reduces the voltage to 1 V in standby mode, which increases safety during maintenance. The device is certified in accordance with international safety standards and has an IP68 / NEMA6P protection rating.
Key Benefits
