Solar Optimizers

Power Optimizers are a hybrid approach to the same problem as micro inverters. Like micro inverters, a power optimizer is attached to each panel in an array. However, rather than simply converting DC to AC directly like micro inverters, power optimizers use MPPT technology to match the DC voltage output of the solar panels to the performance of a central string inverter. In this way, they avoid the issues of large solar panel strings while keeping the most expensive electronics central, resulting in a lower price-per-watt than micro inverters.
