SolarEdge S440-1GM4MRM S-Series power optimizer

SolarEdge S440-1GM4MRM belongs to the latest generation of S-Series optimizers, designed to deliver even greater efficiency and safety for solar power plants. This model is compatible with solar modules up to 440 W from various manufacturers and features higher current capacity, making it ideal for modern high-performance modules.

Each S440 optimizer manages the operation of a single solar module individually. This means that leaves, dust, passing clouds, or shade from a neighbouring building on one module have no impact on the power generation of the rest of the string. Furthermore, this system allows flexible design with different orientations (e.g., East–West) and roof tilts in a single string.

Key benefits:

• Module-level optimization (440 W): Ensures maximum yield from each individual solar module.

• Sense Connect technology: Advanced connector temperature monitoring that prevents overheating and fire risk.

• SafeDC™ fire safety feature: Automatic voltage reduction to a safe 1 V level when the system is shut down.

• Flexible system design: Ability to mount modules on different roof pitches and orientations in a single string.

• Module-level diagnostics: Performance data for each module is sent directly to the free SolarEdge monitoring platform.

• 25-year warranty: Long-term reliability backed by a standard manufacturer warranty.
