Frequently asked questions
What does MID 20-30KTL3-X2 mean, and what size does it cover?
Growatt groups two power classes, 20 and 30 kW, under this MID line rather than a single fixed rating, and the X2 in the name lines up with the two MPPT channels recorded for it. The specs here do not include a nominal AC power figure, so the exact power class needs confirming on the datasheet before sizing an array to it.
How many strings can the Growatt MID 20-30KTL3-X2 track independently?
The Growatt MID 20-30KTL3-X2 has 2 MPPT channels, matching the X2 twin-tracker design in its name. That suits a commercial roof split across two orientations or two separate string groups, letting each half find its own maximum power point instead of being forced onto one shared tracker.
How much DC current can each MPPT input of the Growatt MID 20-30KTL3-X2 accept?
Each of the two MPPT channels on the Growatt MID 20-30KTL3-X2 accepts up to 16 A of maximum DC input current. That figure sets how many strings of a given module current can be paralleled on each of the two inputs without exceeding the inverter's rated limit.
Can the Growatt MID 20-30KTL3-X2 be installed outdoors, and how efficient is it?
The Growatt MID 20-30KTL3-X2 is rated IP66, the sealing level expected of a commercial inverter mounted outdoors, and reaches 98.75 percent maximum efficiency. At its best, barely more than one percent of the DC energy reaching it is lost as heat during conversion to AC.
