EcoFlow DELTA Pro Ultra Inverter + 1 Battery

The EcoFlow DELTA Pro Ultra Inverter + 1 Battery bundle is the starting point for a scalable home backup system. It combines the DELTA Pro Ultra inverter with one 6kWh LFP battery for outage protection and everyday energy management, with room to add batteries later.

DELTA Pro Ultra Inverter

The inverter delivers up to 7.2kW of 120V/240V output to run heavy household appliances. Two MPPT solar inputs (80–450V up to 4,000W and 30–150V up to 1,600W) provide up to 5.6kW of solar input, and it also accepts grid and gas generator power. Paired with the EcoFlow Smart Home Panel 2, it provides automatic switchover during outages; on its own, UPS switchover takes 0–10 ms.

DELTA Pro Ultra Battery

The battery provides 6kWh of LFP storage rated for 3,500 cycles to 80%+ capacity. Its stackable design keeps expansion simple and space-efficient, and it heats itself automatically below -4°F. Charging options include solar, grid and EV charging stations, and the system carries an IP54 rating.
