Sunova eFox H-30E All-In-One Off-Grid Inverter with Battery overview

The Sunova eFox H-30E is a complete off-grid energy storage solution that integrates a 3kW off-grid inverter, 5.12kWh lithium-ion battery, and high-voltage MPPT solar charge controller into a single all-in-one system. The H-series design allows higher PV input voltage, making it ideal for modern residential solar panel strings.

The system delivers pure sine wave AC output, ensuring safe and stable operation for sensitive electronics, household appliances and motor-driven equipment.

Integrated all-in-one system design

The eFox H-30E combines inverter, battery, solar charge controller and system management into one enclosure. This reduces installation complexity, wiring requirements and potential failure points, making it well suited for residential and off-grid applications where simplicity and reliability are essential.

Its compact footprint allows installation in homes, garages, utility rooms or remote locations.

High-voltage solar input and MPPT charging

Unlike low-voltage all-in-one systems, the H-series supports high-voltage PV input, allowing longer solar strings and more efficient panel layouts. The integrated MPPT controller optimises solar energy harvesting throughout the day and improves system efficiency under changing sunlight conditions.

This design reduces cable losses and improves overall solar performance.

Integrated lithium battery storage

The system includes a 5.12kWh lithium-ion (LFP) battery operating at 51.2V nominal, providing reliable energy storage for night-time use and backup power. Intelligent battery management protects against over-charging, deep discharge and abnormal operating conditions, helping to extend battery life.

The battery is permanently integrated, reducing compatibility issues and simplifying system design.

Off-grid and backup power performance

With a 3kW continuous output and high surge capacity, the Sunova eFox H-30E can power essential household loads such as lights, plug circuits, TVs, fridges, freezers, routers and water pumps.

During grid failure or off-grid operation, the inverter automatically supplies power from the battery and solar input, ensuring uninterrupted electricity for critical loads.

System protection and reliability

Built-in protections include overload, short-circuit, over-temperature and battery protection features. These safeguards ensure safe operation of both the inverter and battery system under varying load and environmental conditions.

Active cooling ensures stable operation and long-term reliability.
