Xijia 3000W (Peak Power 6000W) Inverter DC 24V

[Greg Norman]

Hi

I have a Xijia 3000w 24v inverter and like to use with SBMS0. It has two led displays, AC output and DC input. I have disabled both by removing wire to them.  It has a remote on/off toggle switch and a on/off toggle switch on unit itself. Question, can I connect my EXTIO3 to toggle switch on remote or do I connect to toggle switch on unit.

You can first measure the current when switch is closed by powering with a multimeter set on current range (if you have a multimeter).

But since you disabled the voltmeters the current through the switch when ON should be very small not a problem for EXT IO3

Both the switch on the unit and the one on the remote are one and the same thing they are just in parallel so you can connect the EXT IO3 to either one depending which one is more convenient for you
If you need the ability to turn OFF the inverter add the EXT IO3 in series with the switch.
