A negative power reading from an inverter can indicate several things:If the load shows a negative symbol, it means the inverter is in AC coupled mode, selling power back to the grid1.In some cases, an inverter may show negative output current while actively powering a load, which can be confusing2.Balancing loads effectively is crucial, as negative load power readings can occur if the system is not properly configured3.Additionally, negative AC input readings may indicate a significant drain on batteries, suggesting that the inverter is supplying power for both AC output and input4.Understanding these scenarios can help diagnose issues related to inverter performance.
