EcoFlow DELTA Pro Ultra Inverter + 1 Battery + 400W Solar Panel

The EcoFlow DELTA Pro Ultra Inverter + 1 Battery + 400W Solar Panel bundle is a scalable home energy system for daily use and emergency backup. It pairs the DELTA Pro Ultra inverter and a 6kWh LFP battery with a portable 400W solar panel, so you can store power, run heavy household loads and recharge from the sun.

DELTA Pro Ultra Inverter

The inverter delivers up to 7.2kW of 120V/240V output, enough for demanding loads such as central air conditioners and well pumps. It accepts solar, grid and gas generator input, with two MPPT solar inputs (a high-voltage 80–450V port up to 4,000W and a low-voltage 30–150V port up to 1,600W) for up to 5.6kW of solar. UPS switchover takes 0–10 ms, and it runs at under 30dB.

DELTA Pro Ultra Battery

Each battery adds 6kWh of LFP storage rated for 3,500 cycles to 80%+ capacity. The stackable design makes it straightforward to add capacity later, and the battery heats itself automatically below -4°F. The system is IP54 rated.

400W Portable Solar Panel

The included 400W monocrystalline panel is rated at 22.6% efficiency, carries an IP68 rating and folds for transport and storage, making it useful at home or on the road.
