String Inverter Solar Panel Kits

String Inverter Solar Panel Kits

A string inverter is a central unit with inputs for strings (groups) of solar panels. In string inverter systems, solar panels are chained together in series, with the final panel in the chain plugging into an input on the inverter.

For example, a kit may be designed with two strings of 8 panels apiece, for a total of 16 panels.

String inverters are the most cost-effective option when your system is built in full sunlight. However, shading presents problems for string inverters. When one panel in a string is shaded, its output drops, and the rest of the string drops to match the reduced output of the shaded panel.

If your build site is blocked by trees, chimneys or other obstructions, a string inverter alone won’t be enough to get the most out of your solar array. In those scenarios, you’ll want to look at PV optimizer kits or microinverter kits to mitigate the impact of shading.
