The explosion occurred on April 19, 2019, when a malfunction within one of the battery units caused a thermal runaway—a condition where the battery's internal temperature increases uncontrollably, leading to an explosive release of energy.

Impact due to hailstones, wind-blown debris, or even human-caused incidents like vandalism have been one of the common causes. Further, manufacturing defects like tiny imperfections in the glass or structural weaknesses introduced during production also contributed to the mishaps.

While various factors can contribute to an IGBT's demise, three culprits are responsible for the vast majority of field failures: overcurrent, overvoltage, and overtemperature.

This means your solar panel is generating voltage (open circuit), but the circuit is incomplete and therefore cannot generate current. This could be due to a loose or broken wire, a faulty inverter or charge controller, a poor connection, or an internal problem with the panel.
