Collection: Single-phase grid-tied inverters

Single-phase string inverters for grid-connected systems with no battery: the FoxESS S-G2 series at 2.5 kW, 3 kW and 3.3 kW with one MPPT, AFCI arc detection and built-in WiFi and LAN, and the Deye SUN-3.6K-G04P1 at 3.6 kW with one MPPT, CEI 0-21 certification and an IP65 rating.

On a small residential system the inverter is sized slightly below the array's peak power: a DC to AC ratio between 1.1 and 1.25 increases useful hours while giving up almost nothing at midday peaks.

AFCI is protection against DC arcing, among the most frequent causes of fire on solar roofs: it is worth having even where it is not required.
