Connecting two Dyness BX51100 together

Featured Replies

Hi Everyone, 

I have a Lux SNA5000 with one Dyness BX51100 connected. I bought a second one and need some assistance connecting it as no one is interested in helping with a small job. 

So far I know one positive cable must be on one battery and one negative cable on the other battery and then both batteries connected with the parallel cables. 

The earth can I bridge together? 

Lan cable from inverter to battery one in port? 

Battery one to battery two bridge lan ports out to in port? 

What should both batteries dip switches be on. Currently battery running is on dip 3.

 

Would any settings need to be changed on the inverter side? At the moment it's running perfectly. 

Thanks again

From the manual (screenshot) 

On inverter you would set capacity to 200ah

You can bridge the earth

Thank you very much! Any idea how I would change it to 200ah or does an installer have to do it? Many thanks

Do you know if the inverter is communicating with that single battery? What does the inverter show on the screen regarding the battery? 

In general there should be something under menu 03 as that's where the battery settings are

Yes, it's communicating with the battery. It says 100ah and it's happy. I think you might have logged into my inverter originally off the lux power group and updated it for me.
