This is because voltage can drop when you have loose wires as the electricity can flow efficiently. It might think you have a low battery but it is just a loose cable. Connection between N and PE during inverter operation. - The ground relay is useful when an earth-leakage circuit-breaker is part of the. . Now, if I understand things right, an "at rest" nominal 12V battery will show an open circuit voltage of about 12. 10 when discharged to 50%, and about 11. At 10 V, it would be long gone, or at least damaged. Some inverters are equipped with built-in low voltage disconnect (LVD). . If your inverter suddenly shuts down, overheats, or fails to power your equipment, you're not alone. It occurs when the voltage output from the inverter drops below the recommended level, leading to system failures, reduced equipment performance, or even. .
