String Inverters For Solar Panels

A panel string is a group of panels wired into a single input on your inverter.

String inverters for solar panels.

For example this grid tied system contains 24 mission solar 360w panels and one sma sunny boy 7700w inverter. And voltage is handled by the inverter. The inverter appropriately called a string inverter has three string inputs. How string inverters work.

So it follows that mppt performed at each panel by a micro inverter will yield better overall system results than mppt done by 1 string inverter for the whole system. Multiple strings of panels can be connected to a single inverter which transforms the dc electricity produced by the panels into appliance friendly ac electricity. Follow this guide to compare the types of solar inverters the pros and cons and ideal applications for each type of solar inverter to help you make the right choice for your solar. There are multiple ways to approach solar panel wiring.

Your solar panels are arranged into groups connected by strings hence their name. A string inverter is a standalone unit typically installed close to your fuse box and electricity meter and creates alternating current ac from strings of panels. Each string inverter has a range of voltages at which it can operate. String inverter technology has been used for decades.

One of the key differences to understand is stringing solar panels in series versus stringing solar panels in parallel. This means that the performance of the solar panel is reliant on accurate maximum power point tracking or mppt by the inverter.
