Product Description

The EcoFlow DELTA Pro Ultra X Inverter system is engineered for users who require dependable high capacity energy storage combined with efficient solar generation. This complete bundle includes one advanced inverter unit, two Ultra X expansion batteries, and four rigid 400 watt solar panels designed for permanent outdoor installation. Together, these components create a powerful and scalable energy solution suitable for whole home backup, off grid living, and renewable daily energy use.

Designed to support essential appliances and critical circuits, the EcoFlow DELTA Pro Ultra X Inverter delivers robust output and stable performance during outages or when operating independently from the utility grid. The system is built around long lasting battery chemistry and smart energy management, making it an ideal choice for homeowners and professionals seeking energy independence with the flexibility to expand over time.

Whole Home Backup and Energy Control

At the core of this system is the EcoFlow DELTA Pro Ultra X Inverter, which provides up to 12 kW of output power with split phase capability. This allows it to support a wide range of household appliances, including refrigerators, lighting systems, well pumps, and select heating or cooling equipment. When paired with compatible smart switching equipment, the inverter supports rapid switchover during outages, helping maintain continuity for essential loads.

The included Ultra X batteries provide substantial energy storage, allowing users to manage loads efficiently and extend runtime during grid interruptions. With thoughtful circuit planning, the system can be configured to prioritize critical devices while maintaining overall energy efficiency.

Scalable Storage with Advanced Battery Technology

The EcoFlow DELTA Pro Ultra X Inverter system is designed for scalability. The two included Ultra X batteries deliver approximately 12.3 kWh of usable energy storage, suitable for many backup scenarios. As energy needs grow, the system supports expansion with additional battery modules, allowing total storage capacity to reach up to 180 kWh.

The batteries use LiFePO₄ chemistry, which is known for long cycle life, thermal stability, and enhanced safety. This chemistry supports thousands of charge cycles, making it well suited for frequent use and long term installations. The modular design ensures that users can scale capacity without replacing existing components.

Solar Integration and Renewable Recharging

Renewable energy generation is a key advantage of this bundle. The four rigid 400 watt solar panels provide up to 1600 watts of solar input, enabling efficient daily recharging when installed in suitable conditions. These panels are built with durable aluminum frames and weather resistant materials, making them suitable for roof mount, ground mount, or array installations.

When connected to the EcoFlow DELTA Pro Ultra X Inverter, the solar array allows users to reduce reliance on grid power and recharge batteries using clean renewable energy. The inverter supports high voltage solar input, enabling efficient energy conversion and integration with larger photovoltaic systems.

Designed for Durability and Long Term Use

This system is built with reliability in mind. The inverter and batteries are designed for continuous operation, while the rigid solar panels are constructed to withstand outdoor exposure over extended periods. Whether used for emergency preparedness, daily energy offset, or remote living, the components work together to provide consistent and dependable performance.

The EcoFlow DELTA Pro Ultra X Inverter also supports flexible installation options, making it suitable for residential properties, cabins, workshops, and small commercial applications.
