Growatt offers all in one hybrid power for businesses, from 208V storefronts to 480V facilities, with backup, generator control and room to scale.

Growatt WIT parallel system, Bread of Life Church, CaliforniaCommercial energy storage has to earn its place: lower operating costs, keep the business running through outages, and pay back quickly. Growatt commercial hybrid inverters combine solar, battery storage and generator control in a single platform, giving businesses, farms, multifamily properties and public facilities a practical path to energy independence.

Bread of Life Church rooftop installationThe WIT 28–55kW hybrid inverter is designed for the 208V and 220V three-phase services found in most American small commercial buildings. It supports 100% unbalanced loads in backup, 110% continuous overload capacity, built-in UPS and black start, and parallel expansion, delivering whole-building backup without oversizing the system.

Growatt inverters installed at a US solar siteFor larger facilities, the WIT 50–150kW 480V series brings the same hybrid capability to 277/480 V service. A 2.0 DC/AC ratio, a wide 180–1000 V battery window that works with third-party batteries, 160% rated overload capability and smart generator integration give EPCs a flexible platform. Up to 10 units can operate in parallel for off-grid and microgrid projects.

Growatt's 8-18kW SPH series runs on a 48V battery system and supports 208V and 220V three-phase configurations with up to six units in parallel. It's an affordable, low-voltage option for retail, offices and light commercial buildings that want backup power and self-consumption without the complexity of high-voltage batteries.

Solar trackers at a US project siteGrowatt commercial systems are already working across the US in projects sized from 24kW all the way up to 5MW. Certified to UL 1741, UL9540/UL9540A, IEEE 1547 and CEC requirements, with remote generator control, grid-support functions and fleet monitoring through Growatt's OSS portal, every system is backed by Growatt USA's local service team, complimentary installer training and warranty coverage of 10 years.
