Huawei SUN2000-450W-P
Manufacturer documented GLOBAL verified Sept. 3, 2026
Identity
| category | pv_optimizers |
| generation | legacy / withdrawn - superseded by SUN2000-450W-P2 |
| manufacturer | Huawei |
| marketing_name | Smart PV Optimizer |
| model | SUN2000-450W-P |
| note | Distinct product from SUN2000-450W-P2. It has a different MPPT window (8-80 V vs 10-80 V), a different Isc (13 A vs 14.5 A) and a different enclosure size. Do not merge the two. |

| overvoltage_category | II |
| rated_input_dc_power_note | The fetched datasheet text rendered this row as "1,450 W", which is implausible for a 450 W optimizer and is almost certainly a footnote marker '1' running into '450 W'. Recorded UNKNOWN rather than guessed; the verbatim string is preserved in raw_discovered. |

| max_optimizers_per_system | UNKNOWN |
| min_optimizers_per_string | UNKNOWN |
| note | The per-inverter string table could not be read reliably from the fetched PDF; the extraction returned only a range ('4-50') which is not attributable to a specific inverter, so per-inverter limits are recorded UNKNOWN. |
