  • Page 5: Introduction

    1 Introduction 1.1 Application Sunova-eFox-WP series can connect with solar panels, grid (or generator), load, it built-in lithium battery, hybrid inverter and energy management system. Sunova-eFox-WP has four working modes: SOL (Solar first), UEI (Utility first), SBU(Solar-Battery-Utility), SUB (Solar-Utility -Battery). These working modes are described refer to the setting part.
  • Page 6 When PV power is greater than the consumption, and the battery capacity is low, the PV will supply power to the load and charge the battery at the same time. SOL (Solar first): Solar energy provides power to the loads as first priority.
  • Page 7 When PV power is greater than the consumption, and the battery capacity is low, the PV will supply power to the load and charge the battery at the same time. When PV power is less than the consumption, (Solar-Battery-Utility) : and the battery capacity is high,PV and battery Solar energy provides suplay power to the load at the same time.
  • Page 8 When PV power is greater than the consumption, and the battery capacity is low,PV supplies the load and charge the battery at the same time. (Solar-Utility -Battery) : Solar energy provides power to the loads as first priority. When PV power is less than the consumption, and the battery capacity is low, grid supplies power to the load, PV charges the battery, if there is rest PV power, supplies to the load.
