Related: 10 Cost-Effective Solutions for Making Solar Power Work with String Inverters
For real estate and also commercial photovoltaic panel systems, string inverters are frequently utilized. These provide a simple and relatively cheap method to convert direct current (DC) electricity that solar panels generate into alternating current (AC) electricity usable for homes and businesses.
How String Inverters Work
A string inverter connects several solar panels in series to create a string. Next, the inverter transforms the direct current (DC) electricity created by the string into alternating current (AC) electricity. The process entails a series of steps:
DC Power Input: The solar panels produce DC electricity, which sends to the inverter.
DC-to-DC conversion: The inverter’s DC-to-DC converter tweaks the voltage and current input power.
Inversion: After that, AC power is inverting from DC power.
Grid Synchronization: Grid tied inverters synchronized AC power output voltage and frequency to the utility grid.
Benefits of using String Inverters
Cost-Effective : Stringinverters are usually cheaper when we compare them with any other inverter types like microinverters.
Easy to Install:** They are easy to install and have fewer units.
Maximum Efficiency:** Classic stringinverters also lost some energy, but the new ones have reached high efficiencies.
Downsides of String Inverters
Shade Sensitivity — shade on one panel can affect the entire string of inverters
String Config Limits:** Compared with microinverters, they are less flexible because their string configuration must remain within the same string throughout its lifecycle.
String Inverters — Best Suited Use Cases
Residential Solar Systems: For the majority of home solar systems, string inverters are perfectly suitable, especially for homes with a straightforward roof layout and little shading.
Commercial-scale solar systems:** They also work for small commercial systems (e.g., rooftops, ground-mounted).
String Inverter Panel – where to for the Future?
As with all technology, stringinverters are becoming more innovative and efficient with time. Here are just a few examples of some of the more current trends:
Increased Power Density — The string inverter solution has grown more powerful and compact at the same time, which means that more energy can be put out in a smaller footprint.
Ethernet connectivity for online monitoring or MQTT data transmission on the new MPPT technology.
Smart inverter features — Select string inverters have smart features, including remote monitoring and control, energy optimization and integration with home automation systems.
In a nutshell, stringinverters are an effective and consistent option for solar power systems. They may not be as flexible as microinverters, but their simplicity, lower cost and high efficiency make them a close second for many solar installations.
