There may be some fuses in the inverter which may blow, but if there is a fault on the battery cable, then there is no way to disconnect the battery, which may cause a battery melt down. I suppose it may not cause a fire, but there is sure going to be a lot of hydrogen, which with a spark will cause an explosion.
There should at least be a disconnect device close to the battery for safety sake, and not a No 13 spanner to attempt to dislodge the battery terminal.
Using an AC breaker is not recommended, as they will cause a fire when the breaker trips the DC current.
My take is that there should be a double circuit breaker to the input and output of the inverter. If not for anything else, there to safely isolate the inverter in the case of maintenance.
But I suppose you get what you pay for.
If it is a 3Kw inverter, it can draw up to 125A off the 24V DC supply.
