| 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. |

| european_efficiency | 98.2% |
| full_power_mppt_voltage_range | 530~800 V |
| max_ac_apparent_power_va | 27500 |
| max_active_power_note | Huawei support doc EDOC1100253093 row 'Maximum active power (cos phi = 1)' ranges 13,200 W to 27,500 W across the family, i.e. numerically equal to max apparent power. |

| max_dc_voltage_v | 1100 |
| max_efficiency | 98.4% |
| max_input_current_per_mppt_a | 30 A (two-string) / 20 A (single string) - the per-MPPT ceiling is 30 A only when two strings share the MPPT; a single string is limited to 20 A |
| max_output_current_a | 42.0 A / 380 V AC; 39.9 A / 400 V AC; 38.5 A / 415 V AC |

| num_mppt | 2 |
| num_pv_inputs | 4 |
| num_pv_inputs_note | 'Number of MPP trackers 2' and 'Max. number of inputs 4' -> 2 MPPTs with up to 2 strings each on a single unit. |
| oversizing_limits | Recommended max. PV power 37500 Wp against 25000 W rated AC. |

| rated_input_voltage_v | 600 |
| rated_output_current_a | UNKNOWN (a 'Rated output current' row is confirmed to exist in EDOC1100253093 but its per-model values were not returned by the fetch) |
| startup_voltage_v | 200 |
| string_rules | Up to 4 PV strings total across 2 MPPTs; per-MPPT current ceiling depends on how many strings share that MPPT (see max_input_current_per_mppt_a). |
