A 274 fault is caused by a C20 outlet overcurrent. After a C20 overcurrent, it will switch to INV and discharge normally, as long as you have a split load. At this time, the maximum power should be 7200W. The custom charging mode does not support X-Boost. Once the output load exceeds the set charging power, it will cause the 274 fault. If the user needs to charge and discharge a dryer simultaneously, the C20 must be set to fast charging mode.
