According to Tanfon - High Efficiency Solar Micro Inverter and Energy Storage System Solution, Photovoltaic inverters have great research prospects in the following aspects: solar string inverter, solar micro inverter, solar optimizer, solar energy storage system.
This article focuses on the topology and benefits of solar micro inverters:
Solar micro-inverter generally refers to an inverter with a power of 1000 watts or less and a component-level MPPT in a photovoltaic power generation system. The full name is a micro-photovoltaic on-grid inverter.
"Micro" is relative to traditional centralized inverters. The traditional photovoltaic inverter method is to serially connect all the direct currents generated by the photovoltaic cells under sunlight, and then invert the direct current into an alternating current into the grid through an inverter; the micro inverter is for each component. The separate inverter is composed of a solar panel and an inverter.
The advantage is that independent MPPT control can be performed for each component, which can greatly improve the overall efficiency, and can also avoid the DC high voltage, poor light effect, and barrel effect of the centralized inverter.
From the current point of view, the advantages of the micro-inverter are very obvious. In practical applications, if the string inverter fails, it will cause several kilowatts of the battery board to fail to function, and the micro-inverter failure will affect the impact. Quite small, it can be seen that the prospect of micro-inverters is very broad, I believe that in the future, micro-inverters will set off a wave of changes in the field of inverters. As a new type of photovoltaic grid-connected device, photovoltaic micro-inverter has broad development prospects.
Inverter is the core equipment of photovoltaic system. Solar photovoltaic cells convert light energy to dc electricity, which is then converted through the inverter to 50 hz, 230/400 v three-phase or 230v single-phase ac.When using inverters in photovolta
Solar pv micro inverters technology is a kind of MLPE technology, it has been a hot market. According to the data, more than half of the roofs of most photovoltaic power plants use micro-inverters. 1. High safety (1) dc voltage is low In the tr
