Through the multiple guarantees of the Company’s module-level power electronics technology, the pain points of the current distributed photovoltaic systemscan be e?ectively addressed:
Safety challenge
Operation and maintenance challenges
Barrel e?ect
Hoymiles Inc.’s microinverters are connected to a photovoltaic system in parallel, so that the DCside in the system is kept at a low voltage of about 40V, thus fundamentally precluding the rehazard and electric shock risk. Users therefore do not have to worry about re caused by DC arcin the microinverter photovoltaic power station. Even if the microinverter system is brought intoan emergency by any external factors, after the system is shut down, the emergency workers willnot face the risk of electric shock because there is no DC high voltage in the photovoltaic powerstation.
Our microinverters are capable of module-level monitoring. It can monitor the voltage, current,power, and other information at the module level, achieve accurate positioning through onlinelayout charts, remotely monitor the power generation status of each module in real time around theworld, and easily locate fault points and types.
Unstable quality
Our microinverters adopt mature topology schemes in the power supply industry, featuring areliable structure. The aluminum casing is employed to enhance the thermal conductivity of powerdevices to the casing and reduce the internal thermal stress. The IP67 rating of the shells ensuresthat the microinverters is waterproof and can be used outdoors. EPCOS lightning protectiondevices are used, which have passed the most stringent 6000V surge lightning strike test in NorthAmerica. In addition, a 12-year basic warranty is o?ered, which can be extended exibly, to 25years at most, truly realizing worry-free after-sales services.Our microinverters’ module-level MPPT controllers track the maximum power point of eachphotovoltaic module respectively. Even if one photovoltaic module is inefficient, the MPPTcontrollers of other modules will continue to maintain their respective maximum productivitye?ciency, thus minimizing the impact on the whole photovoltaic system.

The Company has set up the Energy and Resources Management Procedure to reduce energyconsumption, established the Water, Gas, Sound and Solid Waste Control Procedure to strengthen themanagement of emissions during production and reduce the intensity of pollution emissions, and established theEnvironmental Factors and Hazard Identication Management Procedure to avoid environmental risks. Meanwhile,we promote green o?ces, strengthen green consensus, and strive to achieve coordinated development with societyand the environment.Hoymiles Inc. strictly abides by the Environmental Protection Law and the laws,regulations and normative documents on pollution prevention and control,having formulated an internal environmental protection system, and establishedthe environmental management policy: pursuit of excellence, green andenvironmental protection, safety and health. The Company has establisheda sound EHS management framework and assigned full-time EHS managementpersonnel to reduce the discharge of various pollutants and mitigate the negativeimpact on the environment from all aspects of the industrial chain. The Companyhas obtained ISO14001 environmental management system certication. In 2022,no major environmental violations occurred.
Hoymiles Inc. abides by the requirements of the Law of the People’s Republic of China onthe Prevention and Control of Environmental Pollution by Solid Waste (revised in 2016), theStandard for Pollution Control on the Storage and Disposal Site for General Industrial SolidWastes (revised in 2013) in the treatment of solid waste, and the Standard for PollutionControl on Hazardous Waste Storage (GB 18597-2001) (revised in 2013) in the treatmentof hazardous waste. Hazardous wastes and general solid wastes generated during theproduction and R&D are entrusted to qualify professional institutions for disposal. We classifyand seal hazardous wastes, and post labels that meet the requirements on the surface ofpackaging containers. Before transportation, we apply to the local environmental authoritiesfor the transfer of relevant hazardous wastes according to law, and declare the types, output,storage and disposal of hazardous wastes. General waste is delivered by the local qualiedcleaning and removal service provider to the incineration plant or landll designated by thegovernment.
The waste gas from factory production mainly comes from welding dust, and the emissionshall follow the grade II in “Emission Limits of Air Pollutants from New Pollution Sources,” thatis, Table 2 of the Integrated Emission Standard of Air Pollutants (GB16297-1996). We collectall the waste gas generated in the production process through the gas trap hood, and thenfilter it through activated carbon to ensure up-to-standard discharge from the exhaust pipewith a height of no less than 15m. The emission concentration of treated waste gas meet therequirements of industrial control standards and related laws and regulations.The production process of Hoymiles Inc. does not involve water and thus no industrialwastewater is caused. Domestic sewage shall be subject to Grade III standard in the IntegratedWater Discharge Standard (GB8978-1996) (NH3-N shall be subject to Indirect DischargeStandard for Nitrogen and Phosphorus Pollutants in Industrial Wastewater (DB33/887-2013)).The drainage system in the factory area is divided into di?erent parts. After being treated in aseptic tank, the toilet sewage will be included in the sewage pipe network together with otherdomestic sewage, and the rainwater pipe network in the factory area is connected to themunicipal rainwater pipe network after being collected.Class II standard of the Emission Standard for Industrial Enterprises Noise at the Boundary(GB12348-2008) is followed. The noise of the factory buildings mainly comes from fans, powerdistribution and water pump equipment. We put such equipment in a separate sound insulationroom in the basement, add a static-pressure vibration reduction foundation during installation,and have a mu?er installed at the fan outlet. At the same time, Hoymiles Inc. carries out noisecontrol in the factory area by monitoring the working environment and checking occupationalhealth to reduce the health hazards of the working environment to employees and otherresidents around.Electric forklifts are frequently used in the factory area of Hoymiles Inc. For motor vehiclesentering and leaving the factory, we take the following measures: set up no-honking and speedlimit signs on the roads close to the entrance and exit, and prohibit vehicles from whistling; uselow-noise ramps at the entrance and exit of underground garages and add sound insulationceilings to prevent any adverse e?ects on other residents around.
