The Greensun Solar GSM-MN12R/132HBD-625W is a 625 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 |
|---|---|---|---|
| GSM-MN12R/132HBD-630W | 630 W | 49.72 V | 16.07 A |
| GSM-MN12R/132HBD-635W | 635 W | 49.92 V | 16.12 A |
| GSM-MN12R/132HBD-640W | 640 W | 50.12 V | 16.17 A |
| GSM-MN12R/132HBD-645W | 645 W | 50.32 V | 16.22 A |
| GSM-MN12R/132HBD-650W | 650 W | 50.52 V | 16.27 A |
The most critical specs to match are: cell count (must be exactly 132), Voc close to 49.52 V (within ±5%), and temperature coefficient TcVoc close to -0.24%/°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 Greensun Solar GSM-MN12R/132HBD-625W.
