   S-Miles Designer is a WEB-based application developed by Hoymiles Power Electronics Co., Ltd. for dealers/installers of module-level power electronics power stations, providing a convenient and visual process for creating power station designs, as well as module layout and electrical design. We hope that such a platform will create conditions for more people to access renewable energy.

   And making renewable energy more accessible is what Hoymiles has been doing from the very first day of its inception. We have made it our mission to create impactful solar technology that’s accessible to all.

   'Open Energy for All' is the Hoymiles motto. To us, that means everyone should be able to harness the limitless sunshine, and live a greener and smarter life. At the heart of Hoymiles innovations and investments is the objective to put clean, equitable energy in the hands of more people — regardless of financial conditions, technical backgrounds or living space.

   1. Hoymiles' green efforts in numbers(Source: Hoymiles 2022 Annual Report, S&P Commodity Insights. Numbers may be rounded up.)

  • In 2022, we delivered 1.16 million units of microinverters and were recognized as the world’s No. 2 microinverter supplier in shipment terms.Our products have been installed in 140 + countries and regions.Over 2400 GWh of solar power generation supported by inverters.Total installed capacity of nearly supported by inverters 2.6 GW.We reduced 2.4 million tons of carbon emission, which is equivalent to planting 10.9 million trees.

  • Industry-leading innovationWe took the lead to launch the industry-first plug-and-play cable accessories FLEX (HMS Cable System) to cut microinverter installation by 70%. The standard-setting innovation simplifies the installation process, improves flexibility, lowers costs, and makes building solar systems a more enjoyable experience. The modular connectors, terminals and cables have made solar installation a super-simple and fun experience – true no-brainer installation.Decidedly technology ledIn response to growing residential solar demand, we released our first Wi-Fi integrated microinverters DW series for Brazil and APAC and W series for Europe. The whole-new microinverters can directly communicate with either the phone or the monitoring platform without the need for the gateway DTU. This optimized solution perfectly fits with small home solar setups, cutting upfront costs and streamlining installation for homeowners while sticking to the top reliability standards.Accessible solar for allOur FLEX accessories and the W series of Wi-Fi integrated microinverters form an ideal system for balcony solar systems surging in Europe. For urban dwellers living in apartments, the 2-in-1 microinverter makes full use of the limited balcony space and harvests the city sunshine with no waste. Thanks to the ready-made AC cable, you simply insert the plug into a socket and your solar will start to generate power!Next-generation storage To fully utilize solar power, Hoymiles introduced the next-generation energy storage inverters: HYS series and HAS series. Capable of converting DC power to AC and AC to DC, the inverters can get you ready for backup power and store excess power in your batteries. So you’ll no longer need to worry about power outages and take a step further toward energy independence!3. Emission reduction and energy conservationAs a sustainability leader, Hoymiles works hard to ensure that we abide by clean production laws and standards, in order to minimize the environmental impact during the manufacturing process.Solid waste productionHoymiles conforms with the requirements set out in the Law of the People’s Republic of China on the Prevention and Control of Environmental Pollution by Solid Waste and other recognized national standards. Hazardous wastes and general solid wastes produced during the manufacturing process and R&D are entrusted to qualified professional institutions for proper disposal.Waste gas treatmentWaste gas mainly comes from welding dust during manufacturing. We collect any waste gas through the gas trap hood, which is then filtered through activated carbon to ensure industry-standard discharge from the exhaust pipe with a height of no less than the mandated 15 m.Wastewater disposalHoymiles has taken care to devise a production process that negates the need for industrial water usage. Domestic sewage is treated according to the national water disposal standard. The drainage system in our factories is divided into the correct segments and treated accordingly.Noise reduction The noise of the factory buildings mainly comes from fans, power distribution and water pump equipment. We put such equipment in a separate, sound-proofed room in the basement of our facilities, and we implement a host of noise reduction measures. We also constantly monitor the working environment in the factory and check occupational health to reduce the health hazards in the factory and the surrounding residential areas.It has never been more important than it is now for individuals, small businesses and large corporations to make actionable changes to their facilities and operations in the pursuit of a greener tomorrow. At Hoymiles, we will always stay true to our mission to make solar energy accessible for all.
