Generally, the inverter output voltage cannot exceed the DC bus voltage in conventional inverters. However, with certain topologies and techniques like voltage boosting, it is possible to achieve a higher output voltage than the DC bus voltage.
The DC bus voltage determines the maximum output voltage the inverter can produce. It''s a key parameter for designing the power stage of the inverter and for ensuring compatibility with the electrical system it will be connected to. Can the inverter voltage exceed the DC bus voltage?
Some inverters will trip or issue an overvoltage fault if the DC bus exceeds a threshold (e.g., 800 V on a 400 V-class inverter). In multi-inverter systems sharing a DC bus, regeneration from one unit can affect others. Solar or battery-connected inverters may have intentionally higher DC bus voltages for MPPT or efficiency reasons.
This guide explains how to troubleshoot a "OV-BUS" error on an Autarco inverter. This error indicates that the voltage in the inverter''s DC bus, which connects to the solar panels, has exceeded the safe operating limit. High DC voltage can damage the inverter''s internal components, leading to malfunctions or permanent failure.
