The Hoymiles HMS-400-1T is a 0.4 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 Hoymiles HMS-400-1T 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 16–60 V. Use the matcher above to find the optimal configuration automatically.
The Hoymiles HMS-400-1T MPPT accepts DC voltages between 16 V and 60 V. At summer temperatures, the string Vmpp must stay above 16 V. At winter temperatures, the string Voc must not exceed the absolute DC limit of 65 V. The matcher calculates these temperature-adjusted checks automatically.
Yes — the Hoymiles HMS-400-1T 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 65 V, Vmpp stays within 16–60 V, and total current stays below 25 A.
