Frequently asked questions
What is the Growatt WIT 4-15K HU used for?
Growatt catalogs the WIT 4-15K HU as a residential energy storage inverter, designed to sit between a rooftop solar array and a home battery bank rather than a commercial installation. Unlike the larger commercial WIT models on this site, this HU designation marks it as a household hybrid unit meant for a single-home system, not for a business-scale site with multiple arrays.
What does the 4-15K span in the WIT 4-15K HU name mean?
The "4-15K" in the WIT 4-15K HU designation names a family spanning roughly 4 to 15 kW of AC power, not the rating of this single unit; Growatt does not state which figure in that range this listing corresponds to. Verified for this entry is a 1000 V maximum DC input voltage and a 20 A maximum DC input current per MPPT channel, both worth sizing strings to directly.
How long can strings be on the Growatt WIT 4-15K HU?
The Growatt WIT 4-15K HU tolerates up to 1000 V of maximum DC input voltage, which is a relatively high ceiling for a residential storage inverter and allows longer strings of panels in series than a 600 V unit would. String length still needs to stay under that 1000 V limit at the coldest expected temperature on site, when panel voltage rises.
Can the Growatt WIT 4-15K HU be installed outdoors?
The Growatt WIT 4-15K HU carries an IP66 enclosure rating, so it is sealed against dust and protected against powerful water jets from any direction, which keeps outdoor wall mounting within its specification. This listing does not record a temperature range or weight, so installers should check the manufacturer's datasheet for those figures before a cold-climate or exposed install.
