Solarbank 4 and STREAM 5000: Distinguishing between PV power, grid output and registration

Correctly interpreting PV input, kWh, grid output and off-grid power: including manufacturer limits and the German plug-in solar rules.

5.000 W PV is not the same as 5.000 W at the wall socket.


Compare Solarbank 4 and STREAM 5000 based on connection type and operating mode, not on the highest power rating on the box. PV input, battery size, grid output, and separate off-grid output define different limits. A high PV input power does not indicate the maximum power your home electrical system can handle.

For Germany, the legal classification must also be examined separately. German Federal Network Agency The EEG special regulations specify a maximum total module output of 2.000 W and an inverter output of 800 VA per connection point. A menu value of 800 W alone therefore does not constitute full approval.


These performance specifications should be on separate lines.


The table is a guide to understanding a quotation, not an electrical connection plan. For each power rating, have the corresponding connection and the necessary equipment combination shown to you. An extension battery, an additional inverter, and a different connection method should not be listed under the same heading.

Anker describes on the Solarbank 4 product page For use above 800 W, installation by a qualified electrician and registration with the grid operator are required. The higher output power mentioned there is not a requirement to simply change a setting in the app.

Specification Significance Do not confuse this with
PV input in W Input limit at the designated PV inputs Permitted feed-in to the house's electrical circuit
Capacity in kWh Amount of energy stored according to the data sheet Continuous output power in kW
On-Grid / Off-Grid Different connections and operating conditions The same permission applies to every use.

The configuration also determines the outcome for STREAM.


EcoFlow differs The stand-alone output ranges from 2.500 W in stand-alone operation to up to 3.000 W under the described additional conditions. The STREAM 5000 and STREAM AC 5000 are not identical: The AC model does not have dedicated PV inputs. Conditions with a PV input cannot be directly applied to this device.

For a concrete offer, the model, version, operating mode, and accessories must therefore match. Ask the supplier for this precise information. A number without a connection specification should not be the basis of your purchase decision.


Why software throttling doesn't solve every problem


After FAQ of the Federal Network Agency When power levels are selectable, the highest selectable power level is decisive. A temporarily lower setting does not change this classification. Therefore, whether a specific device model meets the special rules must be clarified by consulting its documentation.

Calculation example: Two devices, each with 800 VA, together have a total power consumption of 1.600 VA. Two separate sockets do not create two separate power outlets. This example illustrates the calculation; it is not a guide for connecting the devices together.


Which documents should be available before ordering


The Mini Power offer “EcoFlow STREAM series solar battery STREAM 5000 with 1x smart meter“This includes the main unit and a smart meter. It does not imply approval for every electrical circuit, nor does it guarantee that a specific extension has been ordered.”

  • Include the full model number and German version in the offer.
  • Request technical documentation for the intended network connection and the specific device combination.
  • Clarify responsibility for connection testing, registration and sign-up before installation.
  • Do not connect the separate off-grid output to the house installation without an approved concept.

Product comparison based on clarified connection type


Once the connection type and necessary documents are determined, you can proceed with the “Mini Power Memory Finder“Use it for selection. It compares offers, but does not grant network connection or installation approval.”


Review an offer in such a way that no follow-up questions remain unanswered.


Note any existing generating equipment at the same extraction point. Performance limits of the Federal Network Agency These figures do not apply to each individual socket. Therefore, provide the inspecting company with the complete system overview, not just the new storage offer.

Make sure your quote clearly states what will be delivered and what will be installed. Any missing certification should be listed as an open item before you specify the connection type. Keep all the documents specific to your order; a file for a similarly named model is not sufficient.


Frequently asked questions


Are W and VA interchangeable in this comparison?

No. Copy the unit and operating mode exactly from the respective document. The ones mentioned EEG special rules Use this information for the VA inverter. Any wattage rating does not replace this test.
