I have 2 eg4 6500’s and 2 raw lifepos. Just installed SA and starting to run AC’s for summer. Here’s whats going on:

15kw array charges 14kwh batteries to100% by around 11am after which the pv input drops to match load but the batteries begin begin draining.

What gives? Is there a setting ive messed up?923FD1C5-3D7F-42EC-9920-B4ECA93314C4.jpeg

What is the power draw for the inverters? You are probably drawing more power than the panels can generate based on your SA screen.

Thats definitely not the issue. Array is 15kw and im getting 7500watts peak before the batts are charged. Once they are charged it drops to match the load but still pulls form the batteries.

Verify with a clamp meter yet?
 
You said you have two 6500 inverters...both with PV? Parallel? How are they configured?
 
Welp, looks like SA is not accurate for battery draw. Daly BMS's show 0 Load on the batteries while SA shows 500. Guess I need to work on getting battery comms working!! Thanks Everyone.
 
I know what the issue is.You have to go and enable use timer and set up specific wattage and percentage. This issue occurs when you don't have the use timer box checked. Battery usage will drop to 0 watts if you set it up like mine here.
