The TCL Zhonghuan HSM-BD54-DA470 is a 470 W solar panel. Finding a compatible replacement requires matching the original electrical characteristics — particularly Voc, Vmpp, Isc, and temperature coefficients — to ensure safe operation within the same string.
Use the form above to find panels that match these specifications. Then verify the replacement in the String Compatibility Calculator with your inverter.
| Model | Power | Voc | Isc |
|---|---|---|---|
| HSM-BD54-DA440 | 440 W | 40.82 V | 13.92 A |
| HSM-BD54-DA445 | 445 W | 40.88 V | 13.99 A |
| HSM-BD54-DA450 | 450 W | 40.94 V | 14.06 A |
| HSM-BD54-DA455 | 455 W | 41 V | 14.13 A |
| HSM-BD54-DA460 | 460 W | 41.06 V | 14.2 A |
| HSM-BD54-DA465 | 465 W | 41.12 V | 14.27 A |
The most critical specs to match are: cell count (must be exactly 54), Voc close to 41.18 V (within ±5%), and temperature coefficient TcVoc close to -0.2%/°C. If Voc differs significantly, the string voltage at extreme temperatures may shift outside the inverter's MPPT range. The replacement finder above pre-screens all candidates by these criteria.
A higher wattage panel usually has a higher Vmpp or Isc, which can affect string voltage and current. Small increases (up to 10–15%) are typically safe if the other electrical specs align. The replacement finder shows a compatibility score — 'Exact match' means the specs align closely. Always verify the replacement in the String Compatibility Calculator with your inverter before installation.
If the replacement has a significantly different Voc or Vmpp, the string voltage may shift outside the inverter's MPPT range, reducing energy production or causing faults. This effect is amplified at temperature extremes: at low temperatures, voltage rises by the TcVoc coefficient. The replacement finder automatically accounts for this — it scores candidates by how closely the electrical specs match the original TCL Zhonghuan HSM-BD54-DA470.
