The SMA SB 3600TL-21 is a 3.7 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 SMA SB 3600TL-21 has 2 MPPT tracker(s), each supporting 2 input string(s). The exact panel count per string depends on your panel's Voc relative to the MPPT range 175–500 V. Use the matcher above to find the optimal configuration automatically.
The SMA SB 3600TL-21 MPPT accepts DC voltages between 175 V and 500 V. At summer temperatures, the string Vmpp must stay above 175 V. At winter temperatures, the string Voc must not exceed the absolute DC limit of 750 V. The matcher calculates these temperature-adjusted checks automatically.
Yes — the SMA SB 3600TL-21 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 750 V, Vmpp stays within 175–500 V, and total current stays below 20 A.
