SMI800W 800W WiFi Grid-Tie Microinverter Review (2026)
Rating: 4.5 / 5 — Best value smart microinverter · $$
The SMI800W is the microinverter we point most plug-in solar beginners to. It does exactly what a balcony-solar brain should: convert your panel's power to safe household AC, feed it through a normal outlet, and show you live production in a clean WiFi app.
Output & monitoring
Rated 800W with ~96% efficiency and pure sine output. The WiFi app shows real-time and historical production so you can tune your panel angle for more.
Who it's for
Buyers who already have (or will choose) their own panels and want a reliable, app-connected inverter. Pair it with 1-2 ~400W panels for a classic balcony setup.
Verdict
The best balance of price, efficiency and smarts. If you'd rather buy everything together, get the complete AUECOOR kit instead.
