One inverter per panel, and one shaded panel stops costing the others · review
An 800 W EcoFlow Stream micro-inverter for two panels with WiFi monitoring through the EcoFlow application and a stated fifteen-year manufacturer warranty.
The bottom line The longest warranty in this family by a wide margin, on the only micro-inverter here that publishes no ingress rating. Those two facts sit oddly together on a device that spends its life outdoors.
An 800 W EcoFlow Stream inverter sold on the application and the warranty.
Stated in the fourth bullet as a manufacturer warranty. Four of the seven micro-inverters here state no warranty at all, and none of the others reaches half this. On a device meant to sit behind a panel for a decade, that is the specification that matters most commercially.
No IP rating. Every other micro-inverter in this family publishes IP67. This one publishes nothing about its enclosure, which is the odd half of a fifteen-year promise about outdoor equipment.
EcoFlow’s own, over WiFi, showing output in real time alongside cost and CO2 saved. The same application covers the STREAM battery elsewhere in this catalogue, which is the practical argument for staying inside one maker’s range.
Up to €250 saved per module. No tariff, no consumption, no generation. It is a projection and it is not carried into the lines above.

They answer different questions: one is a commercial commitment, the other a tested property of the enclosure. A long warranty on a device with no published enclosure rating is unusual, and the rating is worth asking the maker for before mounting it outside.
It is a projection with no tariff, no consumption and no generation figure behind it. This page reports it as a claim and does not carry it into the specification lines.
