Sunova-eFox Series 1 Introduction 1.1 Application Sunova-eFox series can connect with solar panels, grid (or generator), load, it built-in lithium battery, hybrid inverter and energy management system. Suno- va-eFox has four working modes: SOL (Solar first), UEI (Utility first), SBU(So- lar-Battery-Utility), SUB (Solar-Utility -Battery). - Page 6 Sunova-eFox Series When PV power is greater than the consump- tion, 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 Sunova-eFox Series 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, and the battery capacity is high,PV and battery (Solar-Battery-Utility) : suplay power to the load at the same time.
