Recommended Posts

Good Day     Guys I am new to the inverter world so if questions are  a bit boring to the more experienced I apologise.   I own a Axpert  3Kva 

24 volt Inverter and my questions  are:

1. Does this axpert come with a built in change over switch.

2. Is there any reason that i need to add a second change over switch  when this unit is connected to a db board.

3.  I have 2 X 12v  AGM  100amp  batteries connect in series  what size battery fuse should I use.

Many thanks in advance

Yes, all the Axperts do.

Yes, for maintenance and if there is a fault. You could get away without one, but it would be a good idea.

Those will be 100 Ah batteries; Ah measures energy. I suggest a 125 A DC rated fuse.
