FAQ
Taking a 5kWh battery pack as an example, calculated at approximately 1 complete cycle per day:
10000 cycles ≈ 27 years of service life
i. Grid-connected scenario [connected to the home grid]
For a single device, the maximum output power of the grid-connected port is 2500W. When expanded with a power pack, the maximum output power of the grid-connected port can be increased to 3000W.
When the system is connected to the grid, the device automatically limits the system’s grid-connected output power to comply with the grid-connected power limit specified by local regulations.
In grid-connected operation, the maximum load capacity of a single device’s AC outlet is 3600W in bypass mode.
ii. Off-grid scenario [not connected to the home grid]
In off-grid mode, the maximum output power of the AC outlet of a single device used as an emergency power supply is 2500W. When expanded with a power pack, the maximum output power of the AC outlet can be increased to 3000W.
A system can include up to six STREAM AC 5000/STREAM 5000 host devices, providing a maximum total output capacity of 18kW.
The initial default settings will limit the maximum output of devices in the system to not exceed the upper limit specified by local regulations in your area.
A system can support up to 6 STREAM 5000 & STREAM AC 5000 units, with a maximum system expandable capacity of 90KWh.
1. Larger capacity: The single unit capacity is 5024Wh, which is several times that of the previous generation. It supports parallel expansion of up to 2 Expansion Batteries, which can expand the host capacity to 15KWh; a maximum of six hosts can be connected in one system, with a maximum capacity of up to 90KWh;
3. Higher grid-connected output: The maximum grid-connected output of a single STREAM 5000 is 3000W, while the single STREAM AC 5000 is 2500W, which can reach 3000W when paired with an Expansion Battery;
4. Sufficient off-grid power: The AC Outlet has a maximum output of 3600W, meeting the needs of high-power electrical appliances;
5. Flexible expansion: Supports stack expansion, a single host can be stacked with 2 Expansion Batteries, with strong expandability;
6. Improved intelligence: Supports intelligent functions such as Intelligent mode and Peak Shaving, making energy management more worry-free.
- Users with dynamic electricity prices can automatically achieve the minimum cost of electricity without changing their own electricity consumption habits;
- For users with time-of-use electricity prices, compared with time-based custom tasks, the intelligent mode will automatically formulate corresponding charging and discharging tasks based on weather forecasts and considering the future PV power generation level.
More peace of mind: During peak concurrent electricity use (e.g., simultaneous operation of EV charging, heat pumps, and ovens), it reduces the power draw pressure on the main circuit and lowers the risk of tripping due to excessively high peaks.
More flexibility: It allows expansion of home electrification without upgrading the grid contract or modifying home electrical distribution.
More convenience: It operates automatically after setting the power limit and time period, eliminating the need for frequent manual intervention.
Prerequisites:
1. There must be sufficient remaining power in the battery;
2. The load needs to be connected to the AC Outlet of the STREAM 5000.
Notes:
- The grid-connected port will disconnect immediately upon detecting a grid power outage and cannot be used for off-grid power supply;
- Do not connect the AC Outlet of the STREAM 5000 to the power grid;
- The actual available duration depends on the load power, remaining battery power, and photovoltaic power.
If the area where you live frequently experiences power outages, it is recommended to keep the battery fully charged to enable seamless switching to backup power in the event of a power outage.
- STREAM 5000 and Power Stream belong to product series with different positioning, adopting different energy management logics and communication protocols;
- Currently, they cannot be added to the same system in the EF App for unified management;
However, Power Stream can be used as a third-party inverter, directly connected to AC OUTLET or home circuit, prioritizing power supply to loads, with any excess supplied to the battery and then fed back to the grid.
First priority: Supply home loads
Second priority: Charge the battery
Third priority: Feed excess energy into the grid
Note: In off-grid situations, the third-party inverter is directly connected to the AC OUTLET. If the output power of the third-party inverter exceeds 3000W, the input of the third-party inverter will be stopped.
2. STREAM AC 5000 can be stacked with EcoFlow STREAM Expansion Battery 5000 and Expansion Battery 3000. One STREAM AC 5000 can be stacked with up to 2 Expansion Batteries, with a maximum capacity expansion of 15KWh (with multiple options: 5KWh/8KWh/10KWh/11KWh/13KWh/15KWh)
[Picture to be added]
A system can support up to 6 STREAM 5000 & STREAM AC 5000 units, with a maximum system expandable capacity of 90KWh.
