The SolarEdge Power Optimizer P401 is a panel add-on box that supports a single high power 60 or 72 cell PV module of up to 400 watts, with a maximum input voltage of 60 volts DC and ISC 11.75 amps. The P401 power optimizer is compatible with all types of residential rooftops. This SolarEdge power optimizer can be connected a PV module in parallel to maximize energy throughput with constant tracking of the Maximum Power Point. The power optimizers monitor the performance of each module and communicate performance data to the SolarEdge monitoring portal for enhanced, cost-effective maintenance.
