Description
Expand your EcoFlow DELTA Pro Ultra system’s storage capacity at a lower cost with the EcoFlow DELTA Pro Ultra Battery (Refurbished). Each refurbished battery pack adds 6,144Wh of LiFePO4 storage to your DELTA Pro Ultra system — the same capacity as a brand-new unit — and has been professionally inspected and tested by EcoFlow technicians to confirm it meets full operational performance specifications.
The DELTA Pro Ultra Battery connects to the DELTA Pro Ultra Inverter via a dedicated expansion port and is automatically recognized, with capacity immediately reflected in the system display and EcoFlow app dashboard. Multiple battery packs can be connected to a single inverter, scaling system storage from the base 6,144Wh up to 30,720Wh per inverter. With three inverters connected via the 50 Amp Hub, total system capacity can reach 90kWh — enough to power a typical home for multiple days through an extended grid outage. LFP chemistry delivers over 3,500 charge cycles with excellent thermal stability, and the inverter manages all charging and discharging automatically, prioritizing solar input when available.
Each refurbished unit may show minor cosmetic wear from prior use, but all electrical systems and battery performance are fully certified by EcoFlow’s inspection process. Professional installation is recommended for integrating additional battery packs into a whole-home system.
Compatible exclusively with EcoFlow DELTA Pro Ultra systems. Backed by EcoFlow’s refurbished product warranty.
