Product information

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.

SolarEdge is a global company and a leader in PV inverters, power optimizers, and module-level monitoring services.  With their invention of an intelligent inverter solution, it has transformed the way power is harvested and managed in solar photovoltaic systems. They have addressed a broad range of solar market segments, from residential to commercial and small utility-scale solar installations.

SolarEdge continues to improve grid-tie solar power generation. In each system, a DC to DC Power optimizer is paired with each solar panel that allows each one to operate on its own and at its highest efficiency. The SolarEdge system has a lot of benefits when designing your own system. For instance, there is no need for string sizing. Different string lengths can be accommodated, and panels don’t have to be facing the same way. They can provide up to 25% more energy production in systems with shading issues.

SolarEdge inverters are designed to work with their optimizers.  Their power optimizers handle the MPPT and voltage separately for each module, which makes their inverters only responsible for DC to AC inversion.  Because of this, it allows them to be less complicated, more reliable and also cost effective with a standard 12-year warranty that can be extended to 20 or 25 years.
