At this year’s SNEC exhibition hosted by Shanghai Photovoltaic Magazine, we interviewed Zhang Lisa, Vice President of Marketing at Growatt. At the SNEC stand, Growatt showcased its new 100 kW WIT 50-100K-HU/AU hybrid inverter, specifically designed for commercial and industrial applications.
Chinese inverter manufacturer Growatt has unveiled a new hybrid inverter solution that easily scales up to 300kW and is suitable for both grid-connected and off-grid applications. Batteries with a capacity of up to 600 kWh can be connected to it. Growatt supplies commercial APX batteries to ensure compatibility, trouble-free operation and service.
The combination of this 100 to 300 kW storage system with Growatt’s APX commercial battery system is ideal for providing backup power or peak load shaving to reduce users’ energy costs. In addition, this new C&I inverter also has grid support functions to achieve optimal integration of distributed energy resources with the grid.
Growatt’s move into large-scale energy storage sees the Shenzhen-based manufacturer using the technology it developed for small residential systems to deliver modern solutions to large corporate and industrial users. For example, Growatt has developed soft-switch battery connection technology to provide a modular power optimizer for each battery pack, so that battery packs of different capacities can be mixed in the same system. Each battery pack can be individually powered as needed and performs automatic balancing. This means that each battery can always be fully charged and discharged without the risk of energy mismatch.
Zhang noted that Growatt is no longer just a solar inverter company. The company’s goal has become broader: creating a complete distributed energy ecosystem based on batteries. The shift is already well underway: the company shipped thousands of storage-ready inverters last year, and as energy storage becomes the core of Growatt’s offerings, both residential and commercial, the company expects storage-ready inverters to quickly take over the top spot. . &myuser.
Zhang believes the adoption of electric vehicles is supporting this trend. Electric vehicles are large consumers of electricity, and as households and businesses purchase electric vehicles, they will need more powerful ESS systems to power one or more electric vehicles. Based in China, Growatt can gain valuable experience in the transition to electric vehicles in its home market, which is on the path to electrification of transport and is ahead of most European countries or the United States.
Growatt has developed its own smart EV charging solution that, when integrated into Growatt’s distributed energy ecosystem, can optimize its own consumption and minimize energy costs. Zhang said the manufacturer also offers smart solutions for heat pumps by integrating GroBoost control units with heat pumps. GroBoost can intelligently switch power to solar or APX ESS to increase its own consumption.
On the residential side, smart EV charging and GroBoost-enabled heat pumps are part of GroHome’s overall smart home solution. Zhang noted that Growatt launched GroHome in 2016 as part of its vision of developing a distributed energy ecosystem. The second generation GroHome is also a battery-based ecosystem that optimizes its own consumption and integrates various appliances, of which the most notable are electric vehicles and heat pumps.
Europe remains Growatt’s most important market, at least in terms of revenue. With more than 50% of revenue coming from Europe in 2022, the EU’s ambitious climate targets will continue to make Europe a key market for Growatt. Production is still mainly concentrated in China, with 3 factories in Huizhou and 1 factory in Vietnam. Zhang said Growatt can easily ramp up production capacity to meet global demand, and it will take less than six months to increase capacity. This is in contrast to Chinese cell and module manufacturers, which typically take longer to ramp up production capacity. In Growatt’s case, we can be confident that the proportion of energy storage-ready inverters will grow as manufacturers increasingly target large global energy consumers, many of which will be used for corporate and industrial applications.
