Extended Energy Harvesting
• High efficiency (low energy loss) inverter design
• Both AC and DC switchgear to disconnect the inverter at night, minimizing standby (tare) losses
• State of the art maximum power point tracking (MPPT) algorithm
• Wide input voltage range
• Intelligent wake-up routine.

• Liberally rated for full power over MPPT voltage range
• Proprietary NEMA 3R enclosure design constructed from long-life G-90 galvanized steel
• Sloped roof to direct rain water to the rear of the enclosure
• Industrial grade design including conformal coated, IPC Class III electronic printed circuit boards with components rated - 40o C to plus 85o C.
• Inverter film capacitors with a 25-year design life
• Power magnetic components with a low temperature rise for long-life operation with continual cycling by the photovoltaic power plant
• Desert, cold weather, coastal (mild salt humidity) and harsh environment options
• Soft start feature to minimize AC in-rush current and potentially harmful grid disturbances.

power gate 50kwEasy Installation and Use
• Single-enclosure solution with multiple cable access locations to minimize field wiring
• Enclosure designed for handling by pallet jack, fork lift or sling/crane
• Optional PV Zone integrated sub-array combiner with current monitoring
• Advanced human machine interface (HMI) with display visible in sunlight and membrane keypad for easy identification of power system status and inverter setup
• Optional electronic ground fault detector/interrupter (EGFDI) eliminating the need to replace fuses in the event of nuisance ground faults in the photovoltaic power
system; the EGFDI also has a tighter trip curve further limiting current in the event of a ground fault
• Insensitive to AC phase rotation
• DC polarity detection and protection
• 208/240VAC version connectable in field to either voltage.

Safety and Standards
• Integrated DC two-pole disconnect switch to isolate the inverter (other than GFDI circuit) from the photovoltaic power system during inverter inspection or maintenance
• Protective cover over exposed power connections
• Certified to UL1741 and CSA 107.1-01 Tested according to IEEE 1547 including IEEE C62.41.2

Grid Interface
• Output transformer for galvanic isolation and to match the inverter output voltage to the grid
• High-speed anti-islanding algorithm.

• Extensive monitoring when supplied with SatCon s proprietary PV View Plus monitoring system (details supplied in separate bulletin)
• Compatible with third party monitoring systems (consult factory for details)
