SolarEdge S440-1DM4MRM optimiser

SolarEdge S440 power optimiser for solar panels up to 490 watts

SolarEdge’s power optimisers allow you to get the maximum output from any PV system. The S440 optimiser is ideal for modules up to 490 Wp. 

Advantages of SolarEdge optimisers:

• S440-1DM4MRM variant for (NL, SWE, BEL, UK, CH)
• Maximum output at module level
• Shading does not affect the entire string
• Continuous MPP tracking
• Module-level monitoring possible
• Higher output during shading and with different orientations
• Modules of different power ratings can be combined without any loss
• Detects abnormal behaviour of PV connectors,
  preventing potential safety issues.

Features of the S440 optimisers:

• MPPT operating range 8–60 V
• Modules up to 490 watts
• 15 A max. short-circuit current
• Easy installation thanks to MC4 connection
• 0.1 m input cable
• 2.3 m output cable
• The SafeDC function automatically reduces the voltage to 1 volt per module in the event of a fault
• Easy mounting on the mounting system using a hammer-head screw
• Compatible with all SolarEdge Inverters
• Min. 8 optimisers per pole for single-phase Inverters
• Min. 16 optimisers per string for 3-phase Inverters
• Minimum of 18 optimisers per string for three-phase Inverters and a 277/480 V grid

Power losses across an entire string caused by shading or varying orientations are a thing of the past with SolarEdge power optimisers. Thanks to module-level MPP tracking, each module is controlled individually, enabling the string to deliver the maximum available power. Simple installation and maximum yield are easily achieved with the S440 optimisers.
