Overview
SolaX Power is the principal international brand of SolaX Power Network Technology (Zhejiang) Co., Ltd., a Hangzhou-based Chinese manufacturer focused on photovoltaic inverters, battery storage, and related energy-management equipment. The company was established in 2012 and developed from a specialist inverter business into a broader supplier of integrated solar-plus-storage systems. Its portfolio covers grid-connected and hybrid inverters, storage batteries, all-in-one systems, EV chargers, microinverters, heat pumps, monitoring hardware, and the SolaX Cloud digital monitoring platform. The brand is positioned around the integration of solar generation, energy storage, backup power, and household or commercial energy management. Its products are used in residential installations as well as commercial and industrial sites and utility-scale photovoltaic and storage projects. The company has operated beyond China, with reported activity in markets including Australia, Brazil, the United Kingdom, the United States, and other European markets. Its international presence includes cooperation with local distribution and technology partners and participation in energy-storage and virtual-power-plant initiatives. SolaX's early product development centered on energy-storage inverters. It introduced the SK series in 2013 and entered the United Kingdom in 2014 through a partnership with Navitron. In 2015, it worked with LG Chem on a combined residential battery-and-inverter solution pairing SolaX's Hybrid X grid-tied inverter with LG Chem's RESU6.4EX battery. The companies later announced a dual-branded battery product compatible with the X-Hybrid inverter range. SolaX subsequently broadened its offering beyond residential hybrid systems, launching its first commercial string-inverter series in 2021 and introducing the three-phase X3-Ultra hybrid range for commercial rooftop applications in 2023. Battery sourcing has included products or cells from external suppliers such as LG Chem and Rept Battero, while SolaX also markets its own Triple Power battery family. This combination of internally branded products and supplier partnerships reflects the company's effort to provide complete photovoltaic-storage packages rather than standalone inverter hardware. In January 2024, it released the X1-IES and X3-IES integrated energy-storage systems, further emphasizing packaged residential and three-phase solutions. SolaX completed its initial public offering on 3 January 2024 and began trading on the Shanghai Stock Exchange STAR Market under code 688717. The offering raised more than CNY 2.2 billion according to financial-market reporting. The listing marked a significant corporate transition, providing the company with public-market access while it continued expanding its inverter, battery, charging, heating, and software portfolio. SolaX remains an active energy-technology brand whose core business is the manufacture and integration of equipment for distributed solar generation and energy storage.
History
SolaX Power was established in Hangzhou in 2012 as a developer and manufacturer of photovoltaic inverters and energy-storage equipment. Its early identity was closely associated with hybrid solar systems, which combine grid-connected photovoltaic generation with batteries and energy-management functions. In 2013, the company introduced the SK series of energy-storage inverters, establishing a product base for later residential and commercial storage solutions. International expansion began early. In 2014, SolaX entered the United Kingdom through a partnership with Navitron. The relationship helped connect the Chinese manufacturer with the UK solar market and contributed to the brand's development outside its home market. In 2015, SolaX formed a partnership with LG Chem to offer a residential combined battery-and-inverter system. The configuration paired SolaX's Hybrid X grid-tied inverter with LG Chem's RESU6.4EX energy-storage system. In 2017, the partners announced a dual-branded battery product designed to work with SolaX's X-Hybrid inverter family. The company's portfolio later expanded from residential hybrid inverters into a wider energy platform. SolaX developed and sold grid-connected inverters, storage inverters, batteries, accessories, monitoring devices, and cloud-based monitoring services. Its battery strategy included both the SolaX-branded Triple Power range and products or cells obtained from outside suppliers, including LG Chem and Rept Battero. The company also broadened its application scope to commercial and industrial facilities and utility-scale photovoltaic and storage installations. In 2021, SolaX launched its first commercial string-inverter series, marking a move beyond its earlier concentration on residential and small-scale hybrid systems. In 2023, it introduced the X3-Ultra three-phase hybrid inverter range for commercial rooftop installations. The product family reflected the growing importance of larger distributed-energy systems capable of coordinating solar generation, battery storage, and site-level power management. SolaX continued developing integrated products in 2024, releasing the X1-IES and X3-IES systems. These products consolidated inverter, battery, and energy-management functions into packaged systems intended to simplify deployment. The company's broader offer also came to include EV chargers, microinverters, heat pumps, monitoring equipment, and the SolaX Cloud platform. Reported overseas operations and sales activity included Australia, Brazil, the United Kingdom, the United States, and European markets. SolaX was also referenced in connection with Australian virtual-power-plant development in a World Economic Forum report. The company became publicly listed on 3 January 2024, when it completed an initial public offering and began trading on the Shanghai Stock Exchange STAR Market under code 688717. Financial-market reports described proceeds of more than CNY 2.2 billion. The listing represented a major organizational milestone and gave the company access to public equity markets while it pursued continued growth in solar inverters, batteries, charging equipment, heating products, and digital monitoring. SolaX has also been connected with a product-safety issue in Australia. In March 2022, the Australian Competition and Consumer Commission published a recall notice for LG S/A Gen2 home energy-storage system batteries supplied by SolaX Power Aus Pty Ltd. The notice was later supplemented with additional instructions and remedies, and in 2024 affected consumers were advised to shut down recalled batteries until they were remedied. The incident is relevant to the brand's market history because it concerned a storage product supplied through SolaX's Australian operations, although the recalled battery product was associated with LG's product naming. Today, SolaX Power operates as an active solar and energy-storage brand with a vertically broad product proposition. Rather than focusing only on inverter hardware, it presents a connected ecosystem covering generation, storage, electric-vehicle charging, heating, monitoring, and energy management. Its principal markets and applications span households, businesses, industrial sites, and larger photovoltaic projects.
