The P404-MC4 allows shorter string design with SolarEdge inverters, to a minimum of 6 modules per string and is ideally suited to standard 60 and 72 cell modules. This increased flexibility will allow smaller installations to be optimised for maximum energy output. Second generation optimisers from SolarEdge, pioneers of optimiser technology. In addition to the benefits of previous versions of the optimsers such as added energy, flexible design, module level monitoring and safety, the P Series range includes features including: Optimised for high-power modules Faster, simpler Installation requiring just a single screw Compliance with VDE-AR-E 2100-712 Fire Safety standard SolarEdge power optimisers maximise energy from each panel through constant tracking of Maximum Power Point per panel. Optimal efficiency is achieved by automatically maintaining a fixed string voltage and performance can be monitored via the SolarEdge monitoring portal. Each power optimser is equipped with the unique SafeDC feature which automatically shuts down module voltage whenever inverter or grid power are shut down.
