The SolarEdge P400 Power Optimizer is a DC/DC converter that connects to each PV module (up to 400 Watts), replacing the traditional solar junction box and increasing energy output from PV systems by constantly tracking the maximum power point (MPPT) of each module individually. In addition to increasing total system output, module-level MPPT allows for flexible installation design with multiple orientations, tilts, and module types in the same string. When used in conjunction with SolarEdge inverters, P400 Power Optimizers automatically maintain a fixed string voltage, allowing even greater flexibility with longer strings and strings of different lengths in order to design optimal PV systems at sub-optimal sites.
The P400 monitors the performance of each PV module and communicates that performance data to the SolarEdge monitoring portal. It's also equipped with a SafeDC™ feature that automatically shuts down modules' DC voltage whenever the PV sytem's inverter - or grid power - goes offline.
Compatible with most 72- and 96-cell PV modules and all SolarEdge Single Phase and Three Phase inverters.
