The inverter string current and voltage are both negative
Connect the voltage meter negative lead to the string's negative conductor. . The inverter displays a message that the VDC is lowering and do not disconnect it. Turn OFF the AC circuit. . When multiple strings are connected to the same MPPT and the number of photovoltaic (PV) modules varies between strings, the resulting difference in open-circuit voltages causes the higher-voltage strings to backfeed into the lower-voltage ones. Higher Voltage than Expected (Likely Open Circuit) . A ground fault occurs when a normally current-carrying electrical conductor, such as a positive or negative wire in a solar array, comes into contact with grounded metal components of the system, like the racking or conduit. While string inverters are generally reliable and efficient, like any electrical equipment, they can. . The electrical insulation from the PV system to ground is defective or insufficient. If a ground fault occurs, parts of the system may still be live. Touching live parts and cables results in death or lethal injuries due to electric shock. -
