The EcoFlow STREAM AC 5000 is the largest plug-in home battery in the STREAM line-up, packing 5024 Wh of LFP (LiFePO4) cells and up to 2500 W of AC output into a 45.4 kg cabinet measuring 29.5 x 28.7 x 48.9 cm. It combines a back-up port with 0 ms UPS switchover, a 10 000-cycle rating down to 60% capacity and an IP65 housing, so it can stand indoors, in the garage or in a sheltered outdoor spot. A single base unit already covers evening consumption for a typical household, and up to two 5 kWh expansion batteries per tower lift the base set to 15 kWh. Combining up to six STREAM AC 5000 towers reaches a maximum system capacity of 90 kWh.

• 5024 Wh usable per base unit, scalable to 15 kWh per tower and 90 kWh across six towers.
• LFP chemistry rated for 10 000 cycles to 60% capacity and a 10-year warranty.
• 0 ms UPS switchover keeps sensitive devices online during a grid outage.
• Rear socket delivers up to 2500 W to appliances; with at least one expansion, tower output rises to 3000 W.
• Grid feed-in of 800 W on a shared circuit (per most European regulations) or 2500 W on a dedicated circuit.
• Self-heating below 10 °C, <30 dB acoustic level and IP65 housing for outdoor placement.
