    Copyright Declaration Symbol Explanation Inverter should not be disposed of with the household waste. Disposal information can be found in this manual. Don’t work on this inverter until it is isolated from battery, mains supply and on-site PV modules. Danger to life due to high voltage. Inverter holds stored power, wait for 5 minutes to discharge before opening lid.

  • Page 10: Product Overview

    Copyright Declaration 3.2 Product overview The N3 Plus hybrid inverters are designed to work with PV modules, battery, grid power and electrical loads. Hybrid inverter helps to optimize on-site consumption, charge battery with surplus PV power and supply power from battery to meet load. When PV and battery power are insufficient, grid power will be used to support loads.

  • Page 12: Work Mode

    Copyright Declaration 3.5 Work mode The N3 Plus Series hybrid inverter has the following work mode based on the configuration and connected equipment. Work mode: Self Use This mode is applies to areas with low subsidies and high electricity prices. Self-consumption of PV renewable power is the highest priority.
  • Page 13 Copyright Declaration Work mode: Backup Use This mode is applies to 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 has sufficient power to supply loads during a grid outage. PV power and battery power could support the backup load in the event of a blackout.
  • Page 14 Copyright Declaration Work mode: Feed in Use This mode applies to areas 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 power will supply load first, then feed into grid, and the excess power will charge the battery last.
  • Page 15 Copyright Declaration Work mode: Peak Shaving This mode applies to the area where the grid system needs to balance the load. In this mode, the hybrid inverter ensures that the battery is charged during the valley period and discharged during the peak period. PeakLimit: The consumption limits power from the grid side.

  • Page 16: Functions

    Copyright Declaration 3.6 Functions (1) Charge period mode: This function applies the areas with large gaps between peak and valley electricity prices. Users can set time-based schedules to charge the battery using the APP or inverter display. During charging period inverter will use the power from PV or grid to charge the battery.
  • Page 17 Copyright Declaration (3) Export Control: Export control is a limit on the amount of power your solar system that can export into the grid. Users can limit the power export to the grid according to site conditions. Figure 3-16 Zero export control with phase balance Figure 3-17 Zero export control with phase unbalance Note: When setting the power to limit the power export to the grid, the CT or meter is enabled first.
