Micro Inverter Price List
A solar micro inverter is a plug-and-play device used in photovoltaics, which converts direct current (DC) generated by a single solar module to alternating current (AC). Micro inverters contrast with conventional string and central solar inverters, in which a single inverter is connected to multiple solar panels. The output from several micro inverters can be combined and often fed to the electrical grid. Micro inverters can achieve maximum power point tracking (MPPT) at the panel level, which has advantages over central inverters. In this way, the output power of each module can be optimized to maximize the overall output power.
Difference between String Inverter and Micro Inverter
As the core equipment of the photovoltaic power generation system, the inverter is used to convert the variable DC voltage generated by the photovoltaic modules into the alternating current of the mains frequency, which is one of the important system balances in the photovoltaic array system. At present, the common inverters on the market are mainly string inverters and micro inverters. Now, let us compare and analyze between them.
On Grid Inverter vs. Micro Inverter
Solar inverter is the core power conditioning device of photovoltaic system, which accounts for 10-15% of system cost, and has high technical content. Solar inverter converts the direct current generated by solar cells into alternating current energy that can be directly integrated into the grid and load through power electronic conversion technology. However, what is the difference between a grid tied inverter and a micro inverter?
Difference between Solar Central Inverter and Solar Micro Inverter
There are many advantages of micro inverter over central inverter, the first advantage is that micro inverter is performing much better in case of shading, as if there will be a partial shading on a part of our solar system due to chimneys or trees, the overall output power of the string will not be affected, but only the shaded solar panel output power will be affected, while in central inverter the overall output power of the string will be affected, and there will be much power loss. The second advantage is the capability of micro inverter to track maximum power point for each connected solar panel, resulting in high efficiency and output power from the solar system.
What Can the Monitoring System Do?
It's really an important matter to monitor the generation of the solar system, and zthe market nowadays doing such task and providing you the balance between the 2 amount of electrical energies. Monitoring equipment nowadays not only providing energy measurements, but you will be able to control both circuits as well. Also, the monitoring equipment will help you understanding your system well, so can maintain the solar photovoltaic system, and reduce your electricity consumption. The solar systems installers become offering smart monitoring system, which can do many tasks related monitoring and control. Moreover, the monitoring equipment became coming with email alert function, so can inform you when the fault happened, so you can take rapid corrective action accordingly.
Basic Functions of the Solar Power Inverter
The solar panels have a point on their performance curve in which they generate maximum power under a set of circumstances, and this point called (Maximum Power Point), and on the other side, the solar inverter has maximum power point tracking feature "MPPT", so it continuously searches and hunts this point to maximize the generated energy/power from your solar system. offers this feature for each Micro Inverter. The sun radiation intensity varies along the day, and the solar array output varies accordingly, so the first regulation job of the inverter is to accept and regulate such change in DC electricity, trying maximize the DC energy harvest as described in aforementioned second job. Also, grid parameters like voltage, and frequency change with grid loads variation, so the second regulation job of the inverter is to regulate and synchronize all these variables, so the solar system can be connected to the grid safely within power quality specs, and with No disconnection in case of grid tie solar photo-voltaic systems. Another regulation job of the solar inverter is monitoring, and protection for both DC voltage, and AC voltage sides parameters, so it disconnects in case of faults or for safety reasons.
Evolution of Solar Micro Inverter
The micro grid inverter is a small plug and play device which is usually connected to one solar panel/module to convert DC to AC electricity, and that is its mainly difference from other solar string and central inverters which can be connected to multiple solar panels. In addition, the output from several micro-inverters are always connected together to electrically feed one electrical grid panel.
Unique Advantages of Solar Micro Inverter
Mainly in 2 cases the solar micro inverter exhibits unique benefits; The first is when there is shading across our solar panels array, and the second is when we need our solar panels to face different directions due to our roof design. As micro solar inverter will allow every solar panel to run on its own, so if one or more solar panels are affected by shading, this will not affect the output power of our whole solar array, because other panels subjected to sunlight will still produce its maximum power capacity and will not affected by shading solar panels.
Micro Inverter Power Conversion Working Principle
Full name of the micro inverter is micro solar on grid inverter. It generally refers to inverters with power below 1500W and module-level MPPT. It is mostly used in photovoltaic power generation systems. Micro is relatively small compared to traditional centralized inverters. The micro inverter inverts each component. Its advantage is that each component can be independently controlled by MPPT, which can greatly improve the overall efficiency. At the same time, micro inverter can also avoid the DC high voltage, poor light effect, and wooden barrel effect of the centralized inverter. Micro inverters manage the collection of solar energy at the level of a single panel to improve the efficiency of the solar equipment, rather than working in the entire system like a central inverter. In the past, in order to ensure maximum power output during solar energy harvesting, the complex control mechanisms used increased costs and restricted the acceptance of micro-inverters. Complex and cost-effective IC and processor-based solutions can handle the logic control of micro inverter designs. Various voltage controllers and regulators also provide complementary solutions for solar panel DC output power generation.
What are the Advantages of Micro Inverter?
The inverter plays an important role in the photovoltaic grid-connected system design. It can convert the solar energy into DC energy and then invert it to the single-phase AC energy that can be applied by various devices. The micro inverter technology means the technology of directly connecting inverter with single PV module. Each PV module can be equipped with an inverter that can realize AC-DC conversion and can track the maximum power point. It can directly convert the power generated by PV module into the AC energy so that it can realize AC load purpose or it can be transmitted to the power grid.
Optimize Solar PV System with Micro Inverters
As to the optimization of the efficiency and reliability for solar photovoltaic system, a rather new means is to use the micro inverter, which shall be connected to each solar panel. Equipping a separate micro inverter for each solar panel can make the system adapt to changing loads and weather conditions, thereby providing the best conversion efficiency for a single panel and the entire system. The micro-inverter architecture can also simplify wiring, which means lower installation costs. By making consumer solar power systems more efficient, the time required for the system to get back the initial investment in solar technology will be reduced.
Is Solar Micro Inverter Worth buying?
If the solar system is confirmed to be expanded in the future, micro inverters are a good choice. It is easy to continue adding a new unit to the micro inverters. The cost of adding another complete unit to a standard inverter is higher. When the panel faces multiple directions or there is a shading problem, choosing a micro inverter is definitely a value-added product.
