About This Product

The P801-4RM4MRY is a SolarEdge power optimiser designed to work with SolarEdge inverter systems at module level. It sits between PV modules and the inverter to improve energy harvest by reducing mismatch losses and enabling panel-level performance tracking. It has built-in safety shutdown features and is suited for commercial or larger rooftop installations where optimiser technology is required to maximise yield and simplify system design.

Who This Product Suits

The P801-4RM4MRY is suited to solar installers and electrical contractors working on SolarEdge PV systems, particularly larger commercial or multi-panel installations. It’s ideal when you want module-level optimisation on strings of two 72-cell or 144 half-cell modules, or where shading and panel mismatch can affect energy production. It’s not intended as a stand-alone device and must be used with compatible SolarEdge inverters.

Specifications Explained

• P801-4RM4MRY is a module-level power optimiser for SolarEdge systems, enabling each panel to operate at its best and reducing mismatch losses.
• Designed to be paired with SolarEdge three-phase inverters (SE16K and larger), ensuring integrated system performance and monitoring.
• Supports connection of up to two 72-cell or 144 half-cell PV modules per optimiser, reducing device count on larger strings.
• Includes MC4 connectors and a 2.2 m output cable to simplify installation and connection to PV modules and the rest of the DC string.
• Features module-level voltage shutdown for safer installation and emergency response procedures.

Summary

The P801-4RM4MRY is a robust SolarEdge power optimiser tailored for module-level optimisation in larger PV systems. It’s built to integrate with SolarEdge inverters, supports dual high-power modules, and includes features that help installers achieve safer, more efficient and easier-to-service solar arrays. It’s an effective choice for commercial or complex residential installations requiring panel-level performance tuning.
