How the panels are mounted affects operating temperature
Affects only bifacial panels — reflected light increases current, which may change compatibility
Apply worst-case Voc +3% and Isc +5% to account for manufacturing variance. Recommended for safety-critical designs.

The EPEVER TEP8425 is a 4.2 kW inverter suitable for residential and commercial solar installations. The panel matcher above shows all compatible solar panels with optimal string configurations calculated automatically based on voltage, current, and temperature limits.
Use our string sizing calculator for a detailed 7-check compatibility analysis with temperature-adjusted voltage and current calculations.
The EPEVER TEP8425 has 1 MPPT tracker(s), each supporting 1 input string(s). The exact panel count per string depends on your panel's Voc relative to the MPPT range 50–180 V. Use the matcher above to find the optimal configuration automatically.
The EPEVER TEP8425 MPPT accepts DC voltages between 50 V and 180 V. At summer temperatures, the string Vmpp must stay above 50 V. At winter temperatures, the string Voc must not exceed the absolute DC limit of 250 V. The matcher calculates these temperature-adjusted checks automatically.
Yes — the EPEVER TEP8425 is compatible with any solar panel brand as long as the string voltage and current stay within its electrical limits. Panel brand does not affect compatibility. What matters is that the string Voc at coldest temperature stays below 250 V, Vmpp stays within 50–180 V, and total current stays below 80 A.
