I noticed that the fan was running on the inverter so I went to have a look at it. On the app it was saying that it was pulling around 2300 watts. I checked my monitor and it was only showing 6A. I removed all the load from the inverter and the fan kept going and the reading stayed the same. I turned it off then back on and the reading went up to 2400 without any load. I connected the load back to the inverter and it instantly went into overload and shut down. It has been running perfectly set-up like this for about 9 months until now so I can't see it being a set up issue. Any help will appreciated.
