Growatt’s booth at RE+ 2025 showcased the company’s lineup of inverters focused on the US market, including both hybrid and off-grid types, among others.
In the spotlight was the company’s residential hybrid inverter, MIN 3.8–11.4KTL-XH2-US. Combining PV, battery storage, and grid power, this product offers a single-phase output power range of 3.8 kW to 11.4 kW. According to the company, the MIN series inverter’s flexibility with multiple power sources, conversion efficiency, and emergency backup functionality together enable household consumers to maximize PV self-consumption. It also supplies uninterrupted power during grid outages or failures. In addition to on-grid, the product is configurable for off-grid operation in the absence of grid power. The capacity of this off-grid system can be scaled up by connecting 3 units in parallel, which ensures the feeding of additional loads. The company’s remote monitoring app, called Growatt ShinePhone, enables homeowners to monitor their operational plant in real-time. It can also schedule energy generation according to regional time-of-day (TOD) tariffs, enabling homeowners to reduce monthly utility bills and instill resilience against dynamic tariff rates.
Growatt also showcased the SPH 12000–18000TL-HU-US(B), designed for larger households or small-scale commercial use cases. Starting with a minimum output power of 12 kW, it supports a maximum connected load of up to 18 kW. In addition to feeding household loads and offering backup, it supports multiple ancillary services, including peak shaving (reducing electricity consumption during peak demand), load shifting (moving consumption from peak hours to off-peak hours), and system startup following a blackout. Pairing with a diesel generator (DG), its grid pass-through function supports a bypass current of up to 200 A during grid outages, offering whole-home backup.
The company introduced its off-grid hybrid inverter, SPE 6000–12000 US, for users without access to grid power. It combines solar, a DG set, and battery storage in a single platform.
Lisa Zhang, Vice President of Growatt, said, “Our new hybrid inverters - the MIN 3.8-11.4KTL-XH2-US and SPH 12000–18000TL-HU-US(B) - represent a major step forward in helping American families and businesses achieve energy independence, cost savings, and sustainability.”
