The Maysun Solar MS440MTDG-48HR is a 440 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 |
|---|---|---|---|
| MS435MTDG-48HR | 435 W | 34.77 V | 15.9 A |
| MS445MTDG-48HR | 445 W | 35.19 V | 16.06 A |
| MS450MTDG-48HR | 450 W | 35.4 V | 16.14 A |
| MS455MTDG-48HR | 455 W | 35.61 V | 16.22 A |
| MS460MTDG-48HR | 460 W | 35.82 V | 16.3 A |
| MS465MTDG-48HR | 465 W | 36.03 V | 16.38 A |
| MS470MTDG-48HR | 470 W | 36.24 V | 16.46 A |
The most critical specs to match are: cell count (must be exactly 96), Voc close to 34.98 V (within ±5%), and temperature coefficient TcVoc close to -0.22%/°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 Maysun Solar MS440MTDG-48HR.
