Regulatory and Compliance Considerations for Home Power Inverter Systems

Introduction

Home power inverter systems have played an important role in our daily life and are becoming more and

 more popular with people.

 With the increase in demand, different brands on the market, manufacturers are gradually increasing,

 many different types of inverters appear so that we can not distinguish whether it meets the standards, 

whether it meets the specifications, whether the safety performance is up to standard, 

the following is a detailed description 

from the model certification, inspection and compliance with local regulations and other aspects.

1.Home Power Inverter Systems information on permits

Inverters must comply with international standards and permits to ensure performance, safety and reliability.

These are only part of the inverter models, these models are the international provisions of the inverter power, 

safety performance, etc., different inverter certification models are different, 

there will be corresponding certification certificates, 

in this respect can not be ignored. It can also be queried in the international certification network thr

ough the model of 

the home power inverter systems , which can also prove the standardization of the inverter.

2.Home Power Inverter Systems inspections

2.1Visual inspection

Shell integrity: First of all, when you get the product, check whether the inverter has cracks, deformation or damage,

 if there are these problems, the first time should contact customer service whether you need to return.

Labels and identifiers: Before using home power inverter systems, first confirm whether the inverter product model, 

specifications, certification marks (such as CE, UL, etc.) are clearly visible, confirm whether these products 

have passed international certification standards, whether there are certification certificates, etc., 

if you are not sure which models are certification standards, you can query the Internet and corresponding identifiers.

Terminal: We also need to check whether the terminal is firm, whether there is loosening or corrosion,

 if there are these conditions, the first time you can ask the customer service, so as to ensure that 

there is no danger in the later use, but also to ensure that the cycle of use becomes longer.

2.2Electrical performance check

Input voltage and current: When using a home power inverter systems, you can first measure whether

 the input voltage and current meet the rated value, and the maximum voltage and current value that

 can operate safely and stably under normal working conditions. The rating is a key parameter determined

 when the equipment is designed and manufactured to ensure that the equipment will not overheat, 

damage or cause safety problems when operating within the rated range.

Output voltage and frequency: At the same time as the input voltage and current, it is also necessary to

 check whether the output voltage and frequency are stable and whether they meet the requirements of

 the equipment, if they are unstable, there may be safety problems.

Efficiency: We also need to test whether the conversion efficiency of the inverter reaches the nominal value.

No-load and load performance: test the working state of the inverter under no-load and load conditions,

 respectively, in daily life there will be no-load and load conditions, if the home power inverter systems in these two cases,

 the working state is not normal, there will be safety problems.

2.3 Safety performance check

Insulation resistance: Use a megohm meter to measure insulation resistance and ensure it meets safety standards.

Grounding check: Ensure that the grounding terminal is properly connected and the grounding resistance meets requirements.

Overload and short circuit protection: Test whether the overload and short circuit protection function is normal.

Temperature test: After running for a period of time, check whether the surface temperature of the inverter is 

within the safe range, and the temperature is too high or too low is not conducive to the operation of the inverter, 

which will reduce the use time of the home power inverter systems.

2.4 Functional check

Switch function: Test whether the switch is normal, this is the most basic check, no matter what equipment is used,

we must test the switch function.

Display and alarm function: While using the power inverter for home solar system, we also check whether 

the display is clear, the display can see the data, if the data is abnormal, you can adjust the inverter through the display.

It also depends on whether the alarm function is normal, such as when you are not at home, there is a fire phenomenon, 

will not automatically alarm. 

Power inverter for home solar system application in our daily life, we should pay more attention to the problem of fire,

many equipment can not withstand the time will easily catch fire, resulting in some fire accidents.

Communication function (if any) : Test whether remote monitoring or communication function is normal.

2.5Environmental fitness check

Temperature range: we have checked the voltage and current, safety performance and other aspects, but also check

 the external environment, the inverter is stored in a suitable environment, too high and too low temperature is not

 suitable for the inverter, so to check whether the inverter works normally in the nominal temperature range, 

so for power inverter for home solar system , you can extend the service life.

Humidity test: Also confirm the normal operation of the inverter in a high humidity environment.

Dustproof and waterproof: Check whether the shell protection level (IP level) meets the requirements, 

whether the dustproof and waterproof meet the standards, in bad weather, under heavy rain or hail, etc.,

 whether it can ensure the safe operation of the home inverter.

3.Power inverter for home solar system adherence to local codes.

Compliance with local regulations for power inverter for home solar system requires certification, technical documentation, 

product identification, installation, environmental compliance and other aspects to ensure that products fully comply with

 local regulations and avoid legal risks and market access issues.

3.1Understand local regulations

Electrical safety regulations: such as CE certification in the EU, UL certification in the United States, CCC certification in China, etc.

Energy efficiency standards: such as the EU ErP directive, the United States Energy Star (Energy Star) and so on.

Electromagnetic compatibility (EMC) requirements: Ensure that the inverter does not cause electromagnetic interference to other devices.

Grid access regulations: for example, VDE-AR-N 4105 in Germany, G59/G83 in the United Kingdom, etc.

Environmental regulations: such as the EU RoHS Directive (Restriction of Hazardous substances) and REACH regulations.

3.2Technical document Preparation

User manual: Provides detailed instructions, installation guides, and safety warnings.

Technical specifications: including input and output voltage, current, power, efficiency and other parameters.

Test report: A test report issued by an accredited laboratory certifying that the product complies with the relevant standards.

Declaration of Conformity: A declaration that the product complies with relevant regulations and standards.

3.3Environmental compliance

RoHS compliance: To ensure that the product does not contain harmful substances (such as lead, mercury, cadmium, etc.), 

whether the material of the product is harmful to the environment, we have to follow the environmental protection of 

the power inverter for home solar system, etc., the environment is very important to us, the inverter needs to 

obtain resources through nature, if the inverter product is not qualified, it is harmful to the environment, 

in violation of international regulations, and can not be used.

Recycling and disposal: Comply with local e-waste recycling regulations and provide recycling information to help the environment.

conclusion

We explain in detail how to choose the right and safe inverter through the three aspects of home power inverter systems licensing, 

inspection and compliance with local regulations. In our lives will ignore these small things, this article is to better remind users to

 check the inverter, from what details to understand the inverter.

SRNE is a normative, standard brand, each inverter below has the corresponding certification and certification standards, 

there is no problem in testing, if there are many inverter brands, do not know how to choose, then try SRNE!
