Product Details & Specifications

Usage & Application Guide

Position the portable trolley stand in a dry garage or utility room and stack the three smart battery modules onto the base. Mount the Delta Pro Ultra X inverter unit directly on top of the battery stack and lock the quick-connect latches. Connect the battery interconnect cables between the inverter and battery modules. Wire your rooftop or ground-mount solar panel array to the PV switch box and plug the solar lines into the inverter's PV inputs. For grid backup, connect the system to an emergency transfer switch or sub-panel installed by a certified electrician. Monitor system performance, charge states, and real-time power draw using the EcoFlow companion smartphone app.

FAQ

Q: Can the EcoFlow Delta Pro Ultra X power a central air conditioner during a blackout?

A: Yes. With a continuous AC power output of 12kW and 240V split-phase support, the system easily handles the surge and running wattage required for heavy-duty appliances, including a 5-ton central air conditioner.

Q: How many total batteries can be added to expand this 18kWh solution?

A: A single Delta Pro Ultra X inverter supports up to 10 battery modules for a total capacity of 60kWh. Connecting three inverters together expands total system storage up to 180kWh with 30 batteries.

Q: Can I charge the system with a gas generator while it is supplying power to my home?

A: Yes. The system supports simultaneous charging and discharging, allowing you to top up the battery bank using solar panels or an external gas generator without interrupting power to connected home appliances.
