The LONGi LR7-72HJD-670M is a 670 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 |
|---|---|---|---|
| LR7-72HJD-665M | 665 W | 55.1 V | 15.28 A |
| LR7-72HJD-675M | 675 W | 55.3 V | 15.44 A |
| LR7-72HJD-680M | 680 W | 55.4 V | 15.52 A |
| LR7-72HJD-685M | 685 W | 55.5 V | 15.6 A |
| LR7-72HJD-690M | 690 W | 55.6 V | 15.68 A |
The most critical specs to match are: cell count (must be exactly 144), Voc close to 55.2 V (within ±5%), and temperature coefficient TcVoc close to -0.21%/°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 LR7-72HJD-670M.
