The München Solar MSMD415M6-PMB5-60SBF is a 415 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 |
|---|---|---|---|
| 380 W | 46.1 V | 10.77 A | |
| 385 W | 46.2 V | 10.82 A | |
| 390 W | 46.3 V | 10.87 A | |
| 395 W | 46.3 V | 10.92 A | |
| 400 W | 46.4 V | 10.97 A | |
| 405 W | 46.5 V | 11.02 A | |
| 410 W | 46.6 V | 11.07 A |
The most critical specs to match are: cell count (must be exactly 340), Voc close to 46.7 V (within ±5%), and temperature coefficient TcVoc close to -0.27%/°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 München Solar MSMD415M6-PMB5-60SBF.
