Frequently Asked Questions

How many solar panels can I connect to the Growatt WIT 20K-XHU?

The Growatt WIT 20K-XHU 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 150–850 V. Use the matcher above to find the optimal configuration automatically.

What is the MPPT voltage range of the Growatt WIT 20K-XHU?

The Growatt WIT 20K-XHU MPPT accepts DC voltages between 150 V and 850 V. At summer temperatures, the string Vmpp must stay above 150 V. At winter temperatures, the string Voc must not exceed the absolute DC limit of 1,000 V. The matcher calculates these temperature-adjusted checks automatically.

Is the Growatt WIT 20K-XHU compatible with all solar panel brands?

Yes — the Growatt WIT 20K-XHU 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 1,000 V, Vmpp stays within 150–850 V, and total current stays below 50 A.
