The RECOM RCM-430-SMD1 is a 430 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 |
|---|---|---|---|
| RCM-420-SMD1 | 420 W | 43.3 V | 12.46 A |
| RCM-425-SMD1 | 425 W | 43.4 V | 12.56 A |
| RCM-435-SMD1 | 435 W | 43.6 V | 12.79 A |
| RCM-440-SMD1 | 440 W | 43.7 V | 12.9 A |
| RCM-445-SMD1 | 445 W | 43.8 V | 13.01 A |
The most critical specs to match are: cell count (must be exactly 320), Voc close to 43.5 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 RECOM RCM-430-SMD1.
