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.

String
The Deye SUN-21K-G04-LV is a 21 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 Deye SUN-21K-G04-LV has 2 MPPT tracker(s), each supporting 3 input string(s). The exact panel count per string depends on your panel's Voc relative to the MPPT range 200–700 V. Use the matcher above to find the optimal configuration automatically.
The Deye SUN-21K-G04-LV MPPT accepts DC voltages between 200 V and 700 V. At summer temperatures, the string Vmpp must stay above 200 V. At winter temperatures, the string Voc must not exceed the absolute DC limit of 800 V. The matcher calculates these temperature-adjusted checks automatically.
Yes — the Deye SUN-21K-G04-LV 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 800 V, Vmpp stays within 200–700 V, and total current stays below 60 A.
