The LONGi LGi7-72CHVD-500M is a 500 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 |
|---|---|---|---|
| 420 W | 52.79 V | 9.75 A | |
| 425 W | 52.99 V | 9.8 A | |
| 430 W | 53.19 V | 9.85 A | |
| 480 W | 52.68 V | 11.23 A | |
| 485 W | 52.88 V | 11.28 A | |
| 490 W | 53.08 V | 11.33 A | |
| 490 W | 53.11 V | 11.38 A | |
| 495 W | 53.31 V | 11.43 A | |
| 550 W | 52.96 V | 12.8 A | |
The most critical specs to match are: cell count (must be exactly 144), Voc close to 53.51 V (within ±5%), and temperature coefficient TcVoc close to -0.2%/°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 LONGi LGi7-72CHVD-500M.
