Power optimizer

Transform solar modules into intelligent modules for maximum power and efficiency

SolarEdge's Power Optimizer is a DC/DC converter that connects to each solar module in a PV system, transforming them into intelligent modules. By constantly monitoring the maximum power point (MPP) of each individual solar module, Power Optimizers increase the system's energy output, which can boost revenues and accelerate the system's return on investment.

By attaching our Power Optimizers to each solar module, installers, electricians and operation and maintenance personnel can easily monitor system performance and locate and resolve problems at any point in the chain with extreme precision.

Each Power Optimizer is equipped with industry-leading safety mechanisms, such as the unique SafeDCTM function designed to automatically reduce the high DC voltage of the modules to a safe level when the inverter or power grid is switched off, for maximum protection of people and property.

Introducing the S Series residential power optimizer

SolarEdge has launched its most innovative residential power optimizer.

The S Series further enhances our industry-leading safety technology, setting a new benchmark for arc flash detection and prevention with SolarEdge's Sense Connect feature (available from 2022 via a firmware update).

We've also streamlined our Power Optimizer range to simplify project design and logistics, shorten installation times thanks to improved cable layout, and evolve each S-Series model to meet changing PV module requirements.

Flexible design with MPPT at module level

Maximum power point tracking at module level allows greater design flexibility, especially for installations with multiple orientations, tilts and module types on the same string. When working with SolarEdge inverters, each Power Optimizer automatically maintains a fixed string voltage, giving installers even more flexibility with longer strings and different string lengths to design optimal PV systems.

SolarEdge Power Optimizers are compatible with all module types, including high-power and bifacial modules.

Key benefits
