EcoFlow STREAM Ultra Home Solar Battery

All-in-One Hybrid System The smart core of the EcoFlow STREAM Power Plant — combining energy storage and a built-in microinverter in one seamless solution. How Does It Work to Drive Your Energy Bills to 0? As the morning sun rises, EcoFlow STREAM Ultra instantly captures solar energy for your home, storing any surplus automatically. At night, this stored power runs your appliances, directly or through the grid. Generating up to 2,218kWh annually, it meets 71.3% of household needs, cutting electricity bills to almost zero¹. 2300W AC output Run two appliances independently via dual AC outlets, with 1,200W output per battery and auto-boost up to 2,300W (on-grid). Pair with another STREAM Ultra or STREAM AC Pro for full 2,300W (on-grid) AC output. The built-in battery ensures off-grid use and backup during outages.
