Power Optimizer | SolarEdge | A World Leader in Smart Energy

Power Optimizer

The SolarEdge power optimizer is a DC/DC converter which is connected by installers to each solar module turning them into smart modules. The SolarEdge power optimizers increase energy output from PV systems by constantly tracking the maximum power point (MPPT) of each module individually. Furthermore, the power optimizers monitor the performance of each module and communicate performance data to the SolarEdge monitoring platform for enhanced, cost-effective module-level maintenance. Each power optimizer is equipped with the unique SafeDC feature which is designed to automatically reduce modules' DC voltage to a safe level whenever the inverter or grid power is shut down (unless connected to a StorEdge Inverter that is operating in backup mode).

The MPPT per module allows for flexible installation design with multiple orientations, tilts and module types in the same string.  When working with SolarEdge inverters, the power optimizers automatically maintain a fixed string voltage, allowing installers even greater flexibility with longer strings and strings of different lengths in order to design optimal PV systems. The SolarEdge power optimizers are compatible with c-Si, thin-film, and high current modules and have a 25-year warranty.

SolarEdge is ready for NEC 2017

Our line of inverters and power optimizers helps you get ready for NEC 2017's revision to 690.12, implemented from 1 January, 2019, by providing an integrated solution for PV Rapid Shutdown System (PVRSS) 2019. The new provision, specifies that conductors within the array’s 1ft boundary are limited to 80 V or less within 30 seconds of rapid-shutdown initiation.


SolarEdge offers the following power optimizer models:

P320-P505 Power Optimizers.

Connected by installers to the PV module and compatible with a wide range of modules

Power Optimizer Model Module Power (1) Module Voc Current
P320 (2) ≤320W ≤48V 11A
P340 ≤340W ≤48V 11A
P370 ≤370W ≤60V 11A
P400 ≤400W ≤80V 10.1A
P405 ≤405W ≤125V (3) 10.1A
P505 ≤505W ≤83V (3) 14A
(1) Rated STC power of the module. Module of up to +5% power tolerance allowed.
(2) Also available with a frame-mounted bracket; can be mounted in advance for quicker installation. Download datasheet.
(3) NEC 2017 requires max input voltage not to exceed 80V


P730-P860 Commercial Power Optimizers.

Commercial solution connecting two modules per power optimizer, for lower installation costs

Power Optimizer Model Module Power (1) Module Voc Current
P730 ≤730W ≤125V (3) 11A
P800p ≤800W ≤83V (3) 14A
P850 ≤850W ≤120V (3) 12.5A
P860 (2) ≤860W ≤60V 22A
(11A per input)
(1) Rated combined STC power of 2 modules connected in series (for the P800p, connected in parallel). Module of up to +5% power tolerance allowed.
(2) Dual input for parallel connection of two modules; when connecting a single module to the optimizer (in case of odd number of modules in the string) seal the unused input connectors with the supplied pair of seals.
(3) NEC 2017 requires max input voltage not to exceed 80V
