EcoFlow STREAM Microinverter
If you just want to offset daytime usage cheaply, the STREAM microinverter is the value pick. Add a STREAM battery later to store surplus. No battery out of the box, so evening benefit is limited until you expand.

The standout balcony system in 2026: a legal 800W output, generous 2,000W of PV input across four trackers, and a built-in battery so evening usage is covered. Expandable if you want more storage later.
