Smart solar 100/20 Load does NOT turn on

Batteries are full.
Lifeo4.
Jumper is off
Load Voltage Reading 0V
App shows Load Off
Battery charges at 10A
Battery 12V system

I changed it to

Always off

None of them works

I played with other menu items but didn’t help.
No customer support
I didn’t have any issues with my cheap Chinese charge controllers. I am disappointed. This one supposed to be the best at $100.

Any ideas before I return it ?
Most likely its defective.

I decided not to use the load connection because it was not reliable for me. I changed the battery setup to 24v. Load output was going to give me 20A / 500W . It is nice to have that option. In the future, may be I’ll try to use it again.

@Ara As you did not mention the type of loads, I cannot comment other than some products are manufactured to less exact standards and tollerances, hence your experience. I experienced some lights won’t work while others did on my 75/15 but have now had my testbench device working reliably for a couple of years without fail.
