The TCL Zhonghuan HSM-ND48-GR455 is a 455 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-ND48-GR435 | 435 W | 34.96 V | 15.85 A |
| HSM-ND48-GR440 | 440 W | 35.16 V | 15.92 A |
| HSM-ND48-GR445 | 445 W | 35.36 V | 15.99 A |
| HSM-ND48-GR450 | 450 W | 35.56 V | 16.06 A |
The most critical specs to match are: cell count (must be exactly 48), Voc close to 35.76 V (within ±5%), and temperature coefficient TcVoc close to -0.25%/°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-ND48-GR455.
