The Must PH18-6548 ECO is a 6.5 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 Must PH18-6548 ECO has 1 MPPT tracker(s), each supporting 8 input string(s). The exact panel count per string depends on your panel's Voc relative to the MPPT range 60–450 V. Use the matcher above to find the optimal configuration automatically.
The Must PH18-6548 ECO MPPT accepts DC voltages between 60 V and 450 V. At summer temperatures, the string Vmpp must stay above 60 V. At winter temperatures, the string Voc must not exceed the absolute DC limit of 500 V. The matcher calculates these temperature-adjusted checks automatically.
Yes — the Must PH18-6548 ECO 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 500 V, Vmpp stays within 60–450 V, and total current stays below 150 A.
