Solar inverter plays a crucial role in the solar power system. The basic function of the inverter is to convert the direct current (DC) of a PV solar panel into alternating current (AC) for the utilization of power. Where most faults in a solar PV system happen, then it’s important to pick a quality solar inverter that will last up to 15 years, to guarantee you get maximum return on your investment. Inverters are usually the most expensive part of the system and it has a shorter life span than a solar panel. Going with a quality inverter is definitely worth it in the long term. We have seen many customers choose cheap solar inverter in beginning; they may have to replace it later. From this perspective, choosing a quality inverter is one if not the most important step when going solar.
Before buying a solar inverter, you should keep in mind a few specific points.
Common inverter types
There are mainly four types of inverters-Grid and Hybrid Inverters which are connected to the electricity grid and further separated into String and Micro Inverters. At that point, there are off-grid inverters for use in remote zones just as central inverters for commercial business and utility-scale solar-based arrays.
Compare the efficiency of different solar inverters
It is necessary to measure the efficiency of the solar inverter when you choose an inverter. Each and every inverter has its own efficiency curve, depends on the brand model & brand. Actually, inverter efficiency is proportional to the amount of power drawn. The efficiency curve is displayed by a chart showing how efficiency fluctuates with input power or voltage fed into it. It’s advised to usually aim for the most efficient capacity a solar inverter can offer when you want to buy it.
How many loads can an inverter handle? Its power output is rated in watts (watts = amps x volts). There are three levels of power rating-a continuous rating, a limited-time rating, and a surge rating. Continuous means the amount of power the inverter can handle for an indefinite period of hours. When an inverter is rated at a certain number of watts that number generally refers to its continuous rating.
The limited-time rating is a higher number of watts than it can handle for a defined period of time, typically 10 or 20 minutes. The inverter specifications should define these ratings in relation to ambient temperature (the temperature of the surrounding atmosphere). When the inverter gets too hot, it will shut off. This will happen more quickly in a hot atmosphere.
