SolarEdge 300 Watt Power Optimizer
IN: Helios H4
OUT: MC4
Manufacturer Part Number: OP300-MV-AH4SM-2NA
SolarEdge power optimizers offer a superior approach to maximizing the throughput of photovoltaic systems using module embedded electronics. With superior efficiency (99.5%) even in mismatched and unshaded conditions and a flexible system design for maximum space utilization, these optimizers can offer a 25% increase in power output over a traditional central inverter.
Features
- Module level MPPT - optimizes each module independently
- Dynamically tracks the global maximum operating point for both modules and PV inverter
- Module-level monitoring for automatic module and string level fault detection allowing easy maintenance
- Electric arc detection - reduces fire hazards
- Unprecedented installer and firefighter safety mode - safe module voltage when inverter is disconnected or off
- Connection of one or more modules to each power optimizer
- Lower installation costs with faster design, less wiring, DC disconnects and fuses
- Easy and flexible installation – use the same installation methods as exist today
- Allows parallel uneven length strings and multi-faceted installations
- Allows connection of different module types simplifying inventory considerations
- Immediate installation feedback for quick commissioning
