Power Optimizer

Turn solar modules into smart 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, and turns them into smart modules. By constantly tracking the maximum power point (MPP) of each individual solar module, Power Optimizers increase the system's energy production, which can increase revenue and accelerate the system's return on investment.

By attaching our power optimizers to each solar module, installers, electricians and operations 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 feature designed to automatically reduce the high DC voltage of the modules to a safe level when the UPS or power grid is shut down, for maximum protection of people and property.

Overview of the S Series Home Power Optimizer

SolarEdge has launched its most innovative residential power optimizer.

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

We have also streamlined our range of Power Optimizers to simplify project design and logistics, shorten installation times with improved cable layout, and evolve each S Series model to meet changing PV module requirements.

Flexible design with module-level MPPT

The tracking of the maximum power point at the module level allows more flexibility in the design, especially for installations with several orientations, inclinations and types of modules on the same line. When working with SolarEdge inverters, each Power Optimizer automatically maintains a fixed string voltage, giving installers even more flexibility with longer chains and chains of different lengths to design optimal PV systems.

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