The main barrier of the energy storage market is the high price of lithium batteries, lack of business model in some regions, and surely the installation and maintenance difficulty of the energy storage system is another constructive factor. However, the market is changing as new solar energy is becoming the main source of grid energy, many countries and regions started to encourage battery storage, especially the distributed energy storage system, and created a profitable business model, believes Lisa Zhang, Marketing Director, Growatt, in an exclusive conversation with Manu Tayal, Associate Editor, Energetica India. Zhang also shared about her company’s latest product offerings for Indian customers, various quality checks performed before final delivery to customers etc. Here’re the edited excerpts from that interaction:

Que: What latest products Growatt will be offerings to its Indian customers?

Ans: India is Growatt’s strategic developing market, we have become the NO.1 solar rooftop inverter supplier in India since 2019, our success codes include the strategy of localization: we have established a service center and warehouse in Hyderabad, hired local Indian sales representatives and more than 20 Indian service engineers in 8 major cities to provide on-site services across India. In addition, Growatt’s strong R&D capabilities support us to always launch the best products to our global customers.

This year, Growatt will bring the flagship product for India’s increasing commercial and industrial (C&I) rooftop PV system demands i.e. MAX 100-125KTL3-X LV. This new product created many ‘highest’ in the market: the highest power density and the highest power rating of a single unit for C&I inverters, also the highest string current up to 16A, perfectly compatible with 600W+ high power modules. Furthermore, with the high efficiency, integrate the online IV curve scanning, PID function, AFCI protection, and PLC communication, all of these could help customers to achieve the highest returns of solar investment.

Besides, Growatt offers the full range of PV inverters with BIS certificates dedicated for the Indian market, covering residential, C&I, and utility-scale diverse scenarios.


Que: In your view, which technology will lead the solar inverter market in the future?

Ans: Much more power generation, safer and smarter are the core values of PV inverters. Any technology that could contribute to these values increase would be leading the market. Currently, Growatt global 400+ R&D engineers focus on technology innovation and develop many leading features for our new PV inverter products, such as the higher efficiency record, one-click diagnosis technology for your whole PV plant, GroHome smart energy system for your future “Green” house, etc.


Que: What is the highest performance rate of Growatt inverters? And do these inverters work as efficiently in all climatic conditions?

Ans: Growatt was born with the technology gene, we focus on product and technology innovation. We created the highest efficiency record for PV inverter in the market early in 2014, IP65 high protection level and -25-60 centi-degree wide operation temperature range make our products suitable for all challenging climatic conditions.


Que: What do you think, why the energy storage solutions market is lacking behind the inverter market?

Ans: The main barrier of the energy storage market is the high price of lithium batteries, lack of business model in some regions, and surely the installation and maintenance difficulty of the energy storage system is another constructive factor. However, the market is changing as new solar energy is becoming the main source of grid energy, many countries and regions started to encourage battery storage, especially the distributed energy storage system, and created a profitable business model. Growatt penetrated this trend very early, and we have invested many resources to develop the best energy storage system, we can provide the total solution of 0-100kW energy storage system for residential and C&I applications. Compared with our competitors, Growatt’s key advantage is to provide the whole system, including the storage inverter, lithium battery, and monitoring: whole system supplier, the whole system service, easy installation and worry-free maintenance. Currently, Growatt already became the global top 2 storage inverter manufacturer according to Wood Mackenzie latest report.


Que: What quality control checks do Growatt performs before final delivery to its customers?

Ans: Quality is the lifeline of Growatt. Thanks to our stringent quality control system, we are able to ensure product quality and provide advanced and reliable products for customers, through which Growatt has earned widespread popularity across the world.

At Growatt, we have developed a five-step quality engineering system that includes design engineering, component engineering, test engineering, reliability engineering, and manufacturing engineering. It’s a rigorous and comprehensive quality framework that ensures product quality in every step of product development and manufacturing.
