Energy storage – ECOFLOW – Stream AC

EcoFlow STREAM AC Energy Storage

The EcoFlow STREAM AC is a compact home energy bank with a 1.92 kWh capacity, designed to meaningfully reduce grid electricity consumption. It is part of the EcoFlow STREAM system and can be connected to an existing installation with a microinverter, allowing you to store PV surplus energy and use it when grid power is most expensive. STREAM AC delivers a continuous output of up to 800 W.

Key features of the EcoFlow STREAM AC:

• Capacity and scalability: Base capacity is 1.92 kWh. The unit can be expanded by connecting up to 6 STREAM AC units, reaching a total of 11.52 kWh.
• Power: Continuous output power is 800 W, enough to run essential household devices (lighting, router, TV, refrigerator) during evening hours.
• Installation: Operates plug-and-play — simply plug it into an outlet with no wiring changes required. Compatible with microinverters from various manufacturers.
• Battery and durability: Uses an LFP (lithium iron phosphate) battery rated for around 6,000 charge cycles (to 70% capacity). The battery is protected against thermal propagation, and the enclosure with aerogel insulation is fire-resistant.
• Ingress protection and operating conditions: Rated IP65 for dust and splash resistance (suitable for indoor or outdoor placement). Operates across a wide temperature range: -20 °C to 55 °C, and includes self-heating that activates at ≤ 5 °C.
• Quiet operation: Noise level is under 30 dB, allowing comfortable placement in a living room or office.
• Management: Controlled via the EcoFlow app (Wi‑Fi/Bluetooth). The app provides real-time monitoring and smart features such as AI‑TOU (automatic charging during lower-cost hours) and Solcast solar forecasts.
• Dimensions: Compact, approximately 255 x 254 x 458 mm and weighing about 21.2 kg.

Who is this a good choice for?

The EcoFlow STREAM AC is ideal for owners of balcony PV systems or small PV installations who want to maximize self-consumption without complex electrical modifications. With quiet operation and IP65 resistance, it provides a flexible, long-lasting (6,000 cycles) energy storage solution.
