AC180 tripping the house fuse

Product Discussion BLUETTI Apex & AC Series
1

Hello from Spain.

I purchased an AC180, and I have it plugged into the wall. On the AC socket, I have an extension board connected to it with a PoE switch, router, Pi, connected, drawing around 20-30W max. My main electricity fuse keeps tripping, and the bluetti is the only new addition to the house in recent weeks. I’ve already gone around disconnecting things from sockets, but it continues to trip 3 or 4 times a day. Now I’ve disconnected the bluetti, and connected my devices to the same socket the bluetti was connected too and the trips have stopped. I purchased this device so I could use it inline to keep my router etc. up, as here in Spain, electricity can randomly go off. Is the AC180 incapable of doing what I need? Any guidance would be appreciated.

There are a few things to check; However, can you post your grid power info, voltage, and frequency i.e. 240 or 120VAC & 50 or 60Hz. Also, check the Firmware updates in the App and make sure the AC180 is up to date.

  1. Check your settings in the App - Check that power is set to the correct frequency for your location - Turn eco mode OFF - Turn Grid Adaption OFF.
  2. What AC180 charge setting are you using i.e. Silent, Standard or Turbo. For the very low load you are using Silent is more than enough. In Turbo mode and depending on the circuit and other loads on it, that circuit may overload.
  3. If the AC180 is below 80% state of charge, will it charge without any devices plugged in and AC/DC load switched OFF, without tripping your house circuit breaker/fuse? If it is not below 80%, use it without plugged into mains until it is. Then without devices plugged in to the AC180, turn, one at a time AC & DC load switches on.
  4. Will your devices work when the AC input is disconnected from the grid? i.e. from the battery and inverter.

    These are fault finding/ process of elimination things you can do that will help others like me assist you. :smile:

    Unfortunately “mind reading” is not one of my skills, lol.

Also can you tell us what you mean by tripping? Is it tripping a branch circuit breaker that is supplying power to the AC180 grid input? Or some other breaker is tripping? What kind of breaker is it? Is a GFCI? Arc Fault?
.
When it is tripping what is the AC180 doing? Is it charging? If so, what is the grid input wattage like?
