EcoFlow STREAM 5000
A 5 kWh solar battery for balconies and gardens: panels plug straight in, it stores sunshine by day and covers the evening, and it can charge on cheap overnight power. EcoFlow insists on a qualified electrician and forbids feeding power in through a household socket.

Common questions
Can I plug the STREAM 5000 into a wall socket?
No, and EcoFlow says so explicitly. It must be connected by a qualified electrician and must not feed power in through a household socket. This is the single most important fact about this product.
What is the difference between the STREAM 5000 and the STREAM AC 5000?
The STREAM 5000 (£1,599) takes solar panels directly. The AC 5000 (£1,499) is the battery-only version for charging from the grid. Both expand to 15 kWh with add-on batteries.
