How a Solar Power Optimizers Work
Like micro-inverters, power optimizers are located at each panel, usually integrated into the panels themselves. However, instead of converting the DC electricity to AC electricity at the panel site, they “condition” the DC electricity and send it to a string inverter. This approach results in higher system efficiency than a string inverter alone.
Similar to micro-inverters, power optimizers reduce the impact of panel shading on system performance, and also offer panel performance monitoring. Systems that use optimizers are typically more affordable than those that use micro-inverters.
