Tips: Solar inverter plays an important role in solar power system

When it comes to solar power generation systems, we think of solar inverters. Because solar power generation must convert DC to AC through inverters to drive household appliances and other loads. Therefore, solar inverters play an important role in solar power generation system.

Since the solar inverter is so important in solar power system, what functions and functions does it have? The main function of the inverter is to convert the variable DC voltage input of the power supply into a non-interference AC sinusoidal output, which can be used by the equipment as well as fed back to the power grid. In addition to DC to AC conversion, the solar inverters can perform other functions, such as disconnecting the circuit, avoiding circuit damage due to current surge, charging batteries, storing data usage and performance, and tracking maximum power point (MPPT), in order to maximize power generation efficiency.

Efficiency is the most important index. Improving the efficiency of solar inverters can save the energy lost in current conversion and thus reduce the production cost of solar power generation. At present, the efficiency of the solar inverter can reach about 97.2%.

Great purchase for this grid tie inverter
I bought this 600W solar grid tie inverter three months ago, I have been using this inverter for 2 months, and so far it works well and I do love it!

My second 500W grid tie inverter
This is my second of this style 500W grid tie inverters. I added sheet metal behind this one to prevent a fire although the case is heavy gauge metal. I will order more.

Acceptable noise
Use a grid-tied solar inverter with a single 300w panel. It works well and has continued to use it for over 2 months without any issues. It was a little loud .

Good quality inverter
Have been using 500W grid tie inverter for 6 months now. I've had to oil the fan bearings once but everything else has been working great. Im running on 120 volts AC.
