How to use Dry Contacts on Axpert inverters

Recommended Posts

Greetings

Im trying to set up a light to go on when the voltage drops bellow 50% which in my case will be 48.5V

I have used the Ports C & NC that will allow the circuit to close when the voltage is higher than the point back to utility or in floating mode just to test if it will work, but im not getting any signals from the dry contacts 

please advise

My power source set to Utility which will work the same as if its SBU or Solar when the battery Battery is fully 

my battery is in floating stage and multimeter shows nothing

I use the contact NC & C to switch a relay . Program 1 is set Sol . Our setup is offgrid . I use program 12 set 50 v to switch the relay off and 13 set to 51v to switch relay on . If you use the NO & C contact you can set 12 to switch on the light and 13 to switch off . Settings 12 and 13 can only adjust in full volts . You can also use program 1 Utility and set on low DC warning .

Thanks @Chris Louwfor the answer 

before i connect the light i wanted to make sure there is power coming from the relay to power up the bulb, but it seems it is not working 

Im testing it to use it in an off grid system by my uncle, the light will switches on when the voltage drops to setting 12 (low voltage) and i will do the same in my house...

I have connected one wire to C and other one to NC which will close the circuit when the voltage is high wether program 1 is set to utility or solar, and i test the voltage with multimeter and it shows nothing just 0.00

Any idea why it is not working for me ?

It's a pair of contacts; there is no power behind it. You have to provide power externally. NC stands for Normally Closed. Try your multimeter on the resistance (Ω) range.

Thank you for replying @Coulomb and @Chris Louw

I feel so dumb now, this is why they are called dry contact they are like switches, i honestly thought i will get a small amount of power from it to trigger the light...

what is the maximum power (V and A ) supply that i can run through it ????

Thanks again for your time i really appreciate it.

@Chris Louw
Yes that's what it shows in the manual user, i just want to double check when you said you are using a 12V power supply.

So i can use the wall outlet in the house like im using phone charger.. !!!
