Intelligent photovoltaic SLM6120 scheme debut

2020-05-11

Photovoltaic power generation has sparked a wave of installation. Relying on technical expertise in high voltage, high current, high conversion efficiency, and ultra-low power consumption, Suming has independently developed an intelligent optimization chip and solution - SLM6120. It integrates three functions: optimization control, voltage limiting long string, and no heat spots. Combined with peripheral circuits, it can achieve safe shutdown and data collection and monitoring functions, covering the recovery of power loss A fully intelligent overall solution for safe photovoltaic and precise operation and maintenance functions.

When a conventional component is obstructed, not only does the power generation capacity of the obstructed substring decrease significantly, but due to current mismatch, it also affects the power generation capacity of the other two substrings of this component and other components connected in series. This current mismatch is common in power plants due to being obstructed, different component orientations, dust and snow accumulation, and inconsistent current after component attenuation. The following figure shows the optimization scheme of the three part sub cascade SLM6120 independently developed by Shuming.
