Under the current trend of energy saving and environmental protection, solar power generation system has gradually come into thousands of households. As one of the core equipments in the solar power generation system, the selection of solar inverter directly affects the stability and efficiency of the system.ECO-WORTHY currently sells a variety of inverters, and this article will provide you with a detailed introduction on how to scientifically and reasonably select the right inverter for you according to your own needs.

I. Define the demand for electricity

First, you need to determine your own electricity needs. Consider the daily power consumption of your home or commercial facility, including the power of various electrical devices, as well as the potential increase in power demand in the future. This will determine the rated output power of the solar inverter you need. In general, the inverter should be rated slightly greater than your actual maximum power demand to ensure stable power supply even when all the devices are running at the same time. 

 

The power of some commonly used appliances is as follows:

(For reference only, please check the label on your appliance for the power level of the specific appliance)

II. ensure the compatibility of other components of the PV system

Next, make sure the inverter you choose is compatible with your solar panels and batteries. The power of the solar panel determines the amount of electricity that can be generated, the capacity of the storage product and the maximum discharge power it supports determines the total amount of electricity that can be used, and the inverter needs to have the appropriate input range to achieve optimal energy conversion. For example, if your battery is a 24V 100AH battery, then the inverter you choose should be a 24V inverter and support a maximum input current of 100A.

III. Choosing Inverter Type

The common types of inverters on the market today are pure inverters, micro inverters and so on.  

The main function of a pure inverter is to convert direct current (DC) to alternating current (AC), and its design goal is to focus on a single inverter task, i.e., to convert DC power from some kind of DC power source (e.g., solar panels, battery storage systems, fuel cells, etc.) to AC power that meets the requirements of the grid standard or other power-using equipment.  

Micro-inverters are suitable for small systems or occasions with severe localized shadowing, and can achieve maximum power tracking at the component level. It is small and lightweight, easy to install in various locations of the PV array without considering the series-parallel relationship between components, and the system expansion can be achieved by simply increasing the number of microinverters accordingly.  

Some of the inverters are pure sine wave inverters, which are capable of delivering pure sine wave AC power comparable to the utility grid, which is of extremely high quality and suitable for connecting all types of AC loads. Pure sine wave inverters are capable of driving loads of various natures, including inductive loads (e.g., motors) and capacitive loads (e.g., capacitors), and can support complex mixed load situations.

IIII. Quality and after-sales service

Lastly, when buying solar inverters, make sure to pay attention to the quality of the product and the manufacturer's after-sales service. High-quality inverters not only have stable performance and long service life, but also excel in safety protection and electromagnetic compatibility. ECO-WORTHY's quality after-sales service is reflected in its timely customer support, professional installation and maintenance consulting services, rigorous warranty policy and user-centered service improvement mechanism. All these show ECO-WORTHY's respect and commitment to every customer, so that users who choose ECO-WORTHY products can not only enjoy green and reliable energy solutions, but also experience the whole process of worry-free and privileged service. 

ECO-WORTHY inverters are pure sine wave inverters.

To summarize, choosing a solar inverter is a task that requires comprehensive consideration of electricity demand, PV modules, inverter type, as well as quality and after-sales service. Only in this way can the solar power system give full play to its performance and bring a continuous and stable supply of green energy to your life or production.
