The Maysun Solar MS725MTDG-66HN is a 725 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 |
|---|---|---|---|
| MS700MTDG-66HN | 700 W | 48.51 V | 18.22 A |
| MS705MTDG-66HN | 705 W | 48.76 V | 18.26 A |
| MS710MTDG-66HN | 710 W | 49.01 V | 18.31 A |
| MS715MTDG-66HN | 715 W | 49.26 V | 18.36 A |
| MS720MTDG-66HN | 720 W | 49.51 V | 18.4 A |
The most critical specs to match are: cell count (must be exactly 132), Voc close to 49.58 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 Maysun Solar MS725MTDG-66HN.
