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 Selfa SFT 4.1 is a 4 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 Selfa SFT 4.1 has 2 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 160–1000 V. Use the matcher above to find the optimal configuration automatically.
The Selfa SFT 4.1 MPPT accepts DC voltages between 160 V and 1000 V. At summer temperatures, the string Vmpp must stay above 160 V. At winter temperatures, the string Voc must not exceed the absolute DC limit of 1100 V. The matcher calculates these temperature-adjusted checks automatically.
Yes — the Selfa SFT 4.1 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 1100 V, Vmpp stays within 160–1000 V, and total current stays below 20 A.
