Description

Nova Electric’s NESR-Series is a highly reliable, modular DC-AC inverter system designed with advanced microprocessor technology, offering the following benefits:

  • Paralleling capability supports up to 32 NESR modules (51.2KW)
  • Seamless switching between AC and DC power sources
  • Input and output fully isolated
  • Wide AC Input Range – 75~132V (120V system) and 150~265V (230V system)
  • High efficiency (~95%)
  • Power factor ≧99

Advanced Protection Features

  • Standard Input Protection: Reverse Polarity / Under Voltage / Over Voltage
  • Standard Output Protection: Short Circuit / Over Temperature

Operating Modes

  1. AC Mode (Default): In this Mode, AC utility power is the main source and DC power is the secondary source. PFC>0.99. Max efficiency is 95%. When the AC Utility fails, the inverter seamlessly switches to DC Input source.
  2. Ratio Mode: Simultaneous DC and AC inputs. The percentage of AC and DC loads can be assigned to 100%. (E.g., if AC is set to 70%, then remaining 30% is DC.) Please note that the AC input power must be higher than 300W after assigning the AC and DC ratio.
  3. DC Mode: In this Mode, DC power is the main source and AC utility power is the secondary source. THD is <3%. Max efficiency is 91%. When the DC input source fails, the inverter seamlessly switches to AC Input source.
