  • Page 5: Important Safety Instructions

    Important safety instructions Please reserve this manual for future review. This manual contains all the instructions about safety, installation, and operation for the NPower series pure sine wave inverter (in the following, referred to as the inverter). Explanation of symbols To enable the user to use the product efficiently and ensure personal and property safety, please read the related words carefully when encountering the following symbols in the manual.
  • Page 6 you find any problem, please contact the transportation company or our company in time.  Follow the instructions before placing or moving the inverter.  Make sure there isn't any arc danger in the operation area before installation.  Inverter input is recommended to connect to the battery. The minimum capacity of the battery (expressed in AH) should be calculated in the following way: 5 times the inverter/battery voltage's rated power.
  • Page 7  Do not open the inverter to operate when it is working.  The AC output with high voltage during the inverter operation, so do NOT touch the connection point; it may cause danger. The dangerous operations which would cause electric arc, fire or explosion ...

  • Page 8: Overview

    Overview Based on a full-digital intelligent technology, the NPower series is a pure sine wave inverter, converting 12/24/48V DC power to 220/230V AC power. With advanced SPWM technology, voltage-current double closed-loop control, and completely isolated inverter technology, the NPower has high-quality electrical parameters and a stronger ability to resist impact load.
