Frequently asked questions
What scale of project suits the GoodWe GTG2?
The GoodWe GTG2 is rated at 121000 W of maximum AC power on a three-phase output, putting it well beyond residential rooftop territory. At that scale it belongs on a commercial or small industrial site with a correspondingly large photovoltaic array, not a home installation, and the three-phase connection requires a matching three-phase electrical supply on site.
How efficient is the GoodWe GTG2?
The GoodWe GTG2 reaches a maximum efficiency of 98.8 percent, a figure typical of large three-phase commercial inverters. Because this is a peak rating rather than a weighted seasonal average, real-world conversion losses across the full range of operating conditions at a commercial site will tend to run a little above the roughly 1.2 percent implied here.
How much DC current can each MPPT input on the GoodWe GTG2 handle?
Each MPPT channel on the GoodWe GTG2 accepts up to 42 A of maximum DC input current. That ceiling sets how many parallel strings, or how large a single high-output string, can be combined onto one input without exceeding the inverter's rated tolerance, a figure any installer needs to confirm before finalizing the string layout.
Can the GoodWe GTG2 be mounted outdoors, and what supply does it expect?
The GoodWe GTG2 carries an IP66 enclosure rating, sealing it against dust and powerful water jets, so outdoor mounting at a commercial or industrial site is within its declared limits. It is also built as a three-phase unit, so the site needs a three-phase grid connection rather than the single-phase supply typical of a home.
