Micro inverters, also known as small inverters, are inverters with a relatively low power. Compared to regular inverters for household or commercial applications, the power of micro-inverters is typically below 1kW, making it more suitable for light-load applications.
A single inverter is responsible for each unit. Higher conversion efficiency than traditional string inverters! Bring you a higher solar power generation experience
Traditional centralized inverters or series inverters usually have a DC voltage of a few hundred volts to a few thousand volts, which is easy to catch fire and difficult to extinguish in the event of a fire. Microinverters are only a few tens of volts DC and are fully paralleled, minimizing safety risks to a large extent.
Module-level MPP tracking, no socket effects, reduces the impact of shading on power generation; Good low light performance as the starting voltage is low at only 20V and it works even in low light.
The low power of micro-inverters has little impact on the power grid, so they can be easily connected and meet the various needs of power grids.
Normally, the service life of the control cabinet inverter is around 10 years. Microinverters can last up to 25 years
No dedicated switch room is required, microinverters can be installed directly behind the modules or on the trusses. Because they are connected in parallel, more inverters can easily be added later to increase the size of the installation, without changing the previous configuration.
Gift socket interface, plug and play. Easy to install

8. Limited Peak Performance Warranty
The relevant effective output data can be found on the type plate on the back of the products. Bluesun Solar assures that the actual performance of the products will decrease slightly over 10 years from the date of purchase. Modules are guaranteed as follows: Modules aged from the date of purchase up to 1 year are protected against a performance degradation of more than 2.5% for monocrystalline modules and 2.5% for polycrystalline modules of the nominal value according to the products nameplate under STC conditions. If the performance degradation exceeds this and Bluesun Solar determines that this performance loss is not due to defective workmanship of the module when the module has been properly installed and used under normal conditions, Bluesun Solar will, at its option, either repair, replace or provide additional modules to compensate for this loss of performance. Modules with an age from the date of purchase between 2 and 10 years are protected against an annual performance degradation of more than 0.55% for modules, which means that the “n” year performance for monocrystalline modules is not less than 98%-0, 55% * (n-1) and for polycrystalline modules not less than 98% -0.55% * (n-1) is (2≦n≦25). If the performance degradation exceeds this and Bluesun Solar determines that this performance loss is not due to defective workmanship of the module when the module has been properly installed and used under normal conditions, Bluesun Solar will, at its option, either repair, replace or provide additional modules to compensate for this power loss (if Bluesun Solar deems it necessary). During the warranty period - 10 years - the maximum degradation of the modules must not exceed the value of 18.82% for monocrystalline modules and 18.82% for polycrystalline modules according to the product nameplate under STC conditions. If the deterioration in performance exceeds this - always within the warranty period - provided that this loss of performance is determined by Bluesun Solar and is not due to defective workmanship of the module when the module has been properly installed and used under normal conditions. 
STC stands for Standard Test Conditions used to measure the performance of solar cells. It includes (a) the light spectrum of AM 1.5, (b) an irradiance of 1,000 W per m2 and © a cell temperature of 25 °C degrees Celsius. Measurements are performed according to IEC 61215 at the junction box terminals according to BluesunSolar's calibration and testing standards (valid at the time of manufacture of the modules).
Once the customer places an order, they agree to these shipping terms. BLUESUN SOLAR DE reserves the right of final interpretation of this clause.
