Three tips for buying a solar inverter

25 Published by admin 4月 23,2020

Many friends in the installation of home photovoltaic power station often worry about how to choose a solar inverter?And after comparison, found the same brand price seller and seller price difference between the big!Go to solar inverter manufacturer to take goods directly?This solar inverter quality assurance and future use of the safety issues are the most important!
In fact, the choice of solar inverter in photovoltaic system is tricky.Consider these aspects: cost, efficiency, and operational characteristics.

Solar inverter cost price
For rural users, the construction of photovoltaic power station is more for financial management to get a reliable guarantee of money for retirement and to save on living electricity.Therefore, when people choose photovoltaic power station, they mainly consider the installation price, which reflects the price of power station components, including solar inverter.
For household system of photovoltaic solar power inverter, is a set of string type solar inverter, its small volume, light weight, in handling and installation is very convenient, don’t need professional equipment and tools, more do not need transformer room, are generally not installed beside the photovoltaic modules, not to a wide range of laying cable forces, supporting the installation cost is low.
Its cost is not external, so where is it?Certainly in its interior, the solar inverter is composed of many components, such as IGBT, fuse, capacitor, sensor, relay, diode, microprocessor, segment, resistance, etc., do not underestimate these components different brands of components are still very different.In addition, solar inverter panel processing, display size is also a big gap.

 

Solar inverter efficiency
Almost all solar inverters have a maximum efficiency of 98 percent or more.The efficiency of solar inverter is the basic guarantee of photovoltaic power generation and user income.User system commonly used group series of solar inverter, battery string input of each group to a solar inverter, inverter and solar energy battery of input string independently MPPT, ensure that each set of string maximum power, even if a particular set of string caused by a lack of solar radiation or disconnected because of malfunction, the other set of string is not affected also continue to normal power.
In practice, the only index considering the efficiency of the solar inverter is power, have to do the EPC companies to compare the two different brands of solar inverter, often using the same board with a with solar power inverter, but it is a kind of method, but not absolutely accurate, here we only speak a little, solar inverter screen shows account can also be artificial operation, also can be software control efficiency, the most accurate or the meter shall prevail.That’s why some users wonder why the Numbers on the solar inverter’s screen are different from the Numbers on the meter.

Off Grid Solar Inverter

Solar inverter performance
We mentioned above that the solar inverter is composed of so many components, and the performance of these components determines the performance of the solar inverter.The solar inverter in the household system is generally equipped with IP65 protection level.
Solar inverter operation process is an exothermic process, in a steady stream of electricity at the same time, there are a lot of heat caused, it will be around the solar inverter should have enough convection space, used to spread out around the heat, the household system usually come in a natural cooling is given priority to, not with a fan, a large solar inverters tend to be fitted with a cooling fan.

Although the solar inverter has IP65 protection level, when you expose it to harsh environment for a long time, it also affects its service life and power generation capacity.Want to want solar inverter stable operation for 10 years, 20 years, for its “care” is essential, although will not be configured on the household system solar inverter room, but try not to expose it and nature, usually will give its roof installed a sunshade.
An important addition: full certification.I believe that we must also be clear about the quality of a product certification safety certification is the guarantee of product safety!
