EcoFlow STREAM AC 5000 Solar Storage Set + 2 x 5000 Expansion Batteries

EcoFlow STREAM AC 5000 Set 15 kWh (STREAM AC 5000 + 2× Expansion Battery 5000) - Retrofit AC Storage

With this set, you can particularly easily retrofit your existing PV system or balcony power plant with a large storage unit: EcoFlow STREAM AC 5000 plus 2× STREAM Extra Battery 5000 – together 15 kWh storage capacity. As an AC-coupled storage, the STREAM AC 5000 is integrated into the home network via a standard outlet – no conversion, no new inverter.

AC coupling: perfect if your PV system is already installed

If the PV system is already running, retrofitting is often the biggest hurdle: new components, adjustments on the DC side, or an inverter replacement. The STREAM AC 5000 bypasses this via AC coupling. It uses the home network as an interface and does not have DC inputs. This generally keeps your existing PV setup intact – and you still reliably shift excess energy to the evening hours.

15 kWh storage: more evening electricity, less grid usage

With 15 kWh total storage (5,024 Wh + 2× 5 kWh), you create a significantly larger buffer for your typical evening and nighttime consumption – such as cooking, washing, working from home, or entertainment. The goal is clear: feed less into the grid, use more yourself.

Plug & Play: ready to start in a few minutes

The STREAM AC 5000 is connected to the outlet via a Schuko cable, and the EcoFlow App guides you through the setup. For basic operation up to 800 W, no professional is required. For power levels above 800 W, a dedicated circuit is recommended.

LiFePO4, emergency power, and UPS: ready for everyday use and outages

The STREAM AC 5000 uses LiFePO4 cells, is designed for up to 10,000 charge cycles, and comes with a 10-year manufacturer warranty.

For emergencies, it offers an off-grid output with a continuous output of up to 3,000 W. The UPS function switches over in under 20 ms, so that important devices (e.g., refrigerator or router) can continue to run without interruption.

Expansion Battery 5000: modular, quiet, and robust

Each STREAM Extra Battery 5000 expands your system by 5 kWh and supports up to 1,800 W charging and discharging power. For long-term use, it features up to 10,000 charge cycles, self-heating battery technology, and a 10-year warranty, among other features. Thanks to its IP65 rating, flexible placement is possible; with under 20 dB, the battery operates very quietly during operation. The dimensions are 295 × 519 × 267 mm.
