Description
SolarEdge P404 Power Optimiser – Rail Mount, MPPT 405 W
The SolarEdge P404 power optimiser is an advanced photovoltaic system component, specifically designed for use with SolarEdge inverters. The device performs individual maximum power point tracking (MPPT) at each panel level, delivering the highest possible efficiency even under partial shading or module mismatch conditions. The P404 version supports modules with a nominal power of up to 405 W and is designed for direct mounting onto the mounting rail structure. The built-in SafeDC system automatically reduces the circuit voltage to a safe level of 1 V in the event of inverter shutdown, disconnection from the grid, or fire — thereby meeting the fire safety requirements of the VDE-AR-E 2100-712 standard.
Key benefits for installers
- Individual monitoring of each PV module — fast fault location and simplified servicing
- Flexible string design — ability to combine modules of different orientation, tilt and power within a single string, allowing maximum use of the available roof area
- Quick mounting onto the rail structure using a single screw
- High maximum efficiency of 99.5% minimises energy losses in the DC path
- IP68 protection rating and operating temperature range from −40°C to +85°C ensure reliability in all weather conditions
