What you need to know is a microinverter?

A microinverter is a converter device connected to a solar panel. Microinverters convert direct current from solar panels into alternating current for use by general household appliances.

What is the difference between microinverters and traditional string inverters?

Microinverters contain the latest solar technology, have less loss during work conversion and are more efficient than string inverters. The traditional string inverter requires the highest conversion efficiency when the solar panel is not blocked. If it is blocked, the working efficiency will be greatly reduced; unlike the string inverter, the micro inverter operates when the solar panel is blocked. case, work efficiency will not be affected. The most important point is that microinverters can automatically cut off the DC power supply in the event of danger, reducing casualties. String inverters do not have this function.

Why do you need a microinverter?

Unlike central inverters, which optimize the entire solar system, microinverters are optimized for the power of each solar panel. This allows each solar panel to exert maximum power when converting DC power and reduces the loss of current conversion.

The BLD microinverter has an independent MPPT control system, which greatly increases the power generation; the efficiency is as high as 96.5%; the IP67 safety level is high; in the event of an accident, the DC power supply will be automatically cut off to ensure personnel safety.

What factors should be considered when choosing a microinverter?

The power of the solar panels used by everyone is different. When we want to choose a microinverter, we need to consider the following five points:

lInput voltage size: Micro inverters come in a variety of sizes and powers, and the voltages applicable to each size are different. When purchasing, it is very important to choose the appropriate voltage according to the power of the inverter. of. During the use of solar equipment, an increase in output power will increase the input current, and vice versa. If the voltage is not taken into consideration, a continuously high input voltage may cause damage to the device; an undervoltage may cause problems with the output regulation and control functions, and ultimately lead to an increase in input current and power consumption.

lEnergy efficiency: Different inverters have different efficiencies. Maximum Power Point Tracking (MPPT) efficiency results in higher overall efficacy and the production of more solar power, allowing solar panels to operate at their maximum efficiency.

lSize requirements for micro-inverters: Small-sized micro-inverters (around 100-500w) are more convenient to install than large-sized and high-power inverters, and the price will also be different. The selection needs to be based on the size of the solar panel.

lMicroinverter warranty period: When choosing a microinverter, you need to carefully read the seller's product and compare the warranty agreement.

lPeak output power size: We can see this data in the product datasheet. High peak AC power output means that the inverter device can handle and input a large amount of power generated by the solar panels into the grid.

The above five points are several factors that we need to pay attention to and be clear about when choosing a microinverter. Of course, you also need to confirm more carefully with the sales staff and local installers when making a purchase.
