Frequently asked questions
What role does the Growatt WIT 15K GTI play in Growatt's storage lineup?
Growatt's own naming marks the WIT 15K GTI as the grid-tied interface variant within its WIT residential storage line, and its own data classes it as a residential storage inverter. That places it alongside the HU-labeled WIT models as part of the same 15 kW-class storage system rather than as a standalone grid-tied string inverter.
What DC input voltage does the Growatt WIT 15K GTI handle?
The Growatt WIT 15K GTI is rated for up to 1000 V of maximum DC input voltage. That ceiling is well above the 600 V typical of small residential string inverters, so longer strings of series-connected modules can be used, which cuts the number of parallel strings and DC combiner connections an installer needs to wire.
What is the maximum DC input current per MPPT on the Growatt WIT 15K GTI?
Each MPPT channel on the Growatt WIT 15K GTI accepts up to 20 A of DC input current. That sets the ceiling on how many parallel strings of a given module's short-circuit current one channel can safely carry, so installers should check their module's Isc rating before wiring more than a single string per input.
Can the Growatt WIT 15K GTI be installed outdoors?
The Growatt WIT 15K GTI carries an IP66 enclosure rating, meaning it is dust-tight and protected against powerful water jets from any direction. That level of sealing supports mounting outdoors on an exterior wall, matching the outdoor-rated enclosures used across Growatt's WIT residential storage line.
