Solaredge optimizers are not sold individually, they are sold exclusively with Solaredge inverters

SolarEdge optimizers are designed to replace the traditional junction box and are used as a DC/DC converter. They are attached to each PV module individually by simply clipping to the PV module frame or rail. Optimizers, as implied by their name, are used to increase the PV systems energy output and efficiency by up to 25%. The optimizers do this by monitoring the maximum power point (MPPT) of each individual PV panel and track each panel’s performance.

The SolarEdge monitoring portal then displays the tracked information, and allows the user to better understand the system’s performance and how best to maintain your array. The SolarEdge optimizers also help stabilize PV performance by mitigating system offsets caused by shading or other situations that cause miss-match output performance. Each optimizer also has a safety feature called the SafeDC which will automatically shut down the system’s DC voltage if for some reason the grid power is shut down.

The SolarEdge optimizers are extremely versatile when it comes to installation. They can be installed in long or short strings and in any orientation. One of the most appealing features is how easy the optimizers can be installed. They are compatible with any c-Si and thin film modules, and are designed to withstand severe weather conditions. SolarEdge also guarantees quality and longevity of the optimizer’s performance by offering a 25 year warranty.
