subcategory three-phase grid-tied smart string inverter (no battery/ESS interface documented on the fetched sources)
variant_note -M5 is a grid-tied string inverter. It shares the 546 x 460 x 228 mm chassis, 21 kg weight, 2 MPPT / 4 input topology and 30 A (two-string) / 20 A (single string) per-MPPT rating with the -MB0 family, but -MB0 adds a two-terminal Smart String ESS interface and -M5 does not. They are NOT the same product.
