    Anti-Islanding Effect Islanding is a condition when grid connected PV/ batteries back feed energy into the Grid when Grid is turned off for maintenance work, putting maintenance personal at serious risk. N3-HV series inverters prevent islanding through Active Frequency Drift (AFD).

  • Page 10: Introduction

    3.2 Basic features The N3-HV Series hybrid inverters are designed to work with PV modules, battery, mains supply and electrical loads. Hybrid inverter helps to optimize on-site consumption, charge battery with surplus PV energy and supply energy from battery to meet load.

  • Page 11: Work Modes

    User Manual 3.3 Work modes The N3-HV Series hybrid inverter has the following work modes based on the configuration and connected equipment. Work mode: Self Use This mode is applicable to areas with low subsidies and high electricity prices. Self-consumption of PV renewable energy is the highest priority.
  • Page 12 N3-HV Series User Manual Figure 3-4 Time of Use Mode Work mode: Backup Use It is suitable for the areas with frequent power outages. When the grid is off, the battery is used as backup power to supply load. This mode ensures that the battery will have enough energy to supply loads during a grid outage. PV and battery could support the backup load in the event of a blackout.
  • Page 13 N3-HV Series User Manual Work mode: Feed in Use This mode applies to the area that has high feed-in tariff and export control. This model prioritizes grid feeds with sufficient PV power to maximize the tariff subsidy earned. a. When the PV power is sufficient, the PV generation will supply load first, then feed into grid, and the excess power will charge the battery last.
