SatCon Powergate Plus 50kW Solar Grid-Tie Inverter and Systems

SatCon PowerGate Plus 50kW Information
50kW Inverter for Larger Solar Power Systems

PowerGate Plus Inverters are the next generation of PowerGate Inverters for commercial and large-scale grid connected photovoltaic power systems that have become recognized for their reliability, energy efficiency and ease-of-use. The 30kW PowerGate Plus Inverter incorporates many of the features of the original PowerGate Inverter plus several improvements that add further value to photovoltaic power systems.

Top slopes down from front to rear

Physical Dimensions:
H 1881 mm (74.0" )
W 1143 mm (45.0" )
D 648 mm (25.5" )

Enclosure rated NEMA 3R
Exterior finish: RAL-7032

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.

Durability
• 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.

Easy 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.

Monitoring
• 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)
