No matter how high-quality your solar panels are, if you don’t choose the right inverter, the system’s overall efficiency will remain limited. The inverter converts the direct current (DC) produced by the panels into alternating current (AC), allowing electricity to be used in homes, businesses, or fed into the grid. For this reason, the inverter functions as the “brain” of the system. To select the right inverter, you should first analyze your purpose of use, system capacity, and the conditions of the installation site.
There are four most common inverter types on the market. Central inverters are designed to collect high power in one location, making them ideal for large-scale installations. String inverters feature multiple MPPTs and allow several strings to be connected independently. They are known for being cost-effective, but shading on a single panel can affect the performance of the entire string. Microinverters are connected to each panel individually. Since each panel has its own inverter, they provide maximum panel-level efficiency. They are especially advantageous for projects with different roof slopes or partial shading. Hybrid inverters are among the most flexible solutions, as they can operate grid-connected and integrate with battery storage systems. With these inverters, you can store excess energy produced during the day and continue using stored energy at night or during power outages.
When choosing an inverter, it’s important to consider not only the inverter type, but also factors such as efficiency, capacity compatibility, cooling system, warranty period, and service support. An efficiency rate of 95% or higher helps you get the most out of your energy production. At Zes Solar, we analyze your project’s needs in detail and provide inverter solutions that best match both your current and future energy requirements. This ensures your system operates reliably, efficiently, and for the long term.
