Dyness 5.12kWh Block idle discharge?

So I recently got my solar system running and have been monitoring usages very closely.

One thing I noticed is that my Dyness battery loses charge while not in use and due to my schedule tops up after a while to keep it at 100%

From what I can see, it would drop about 1% to 2% every 3 hours while idling and not in use. This happens during the day when I dont allow discharging and at night where it drops from 85% to 80% while eskom is on. 

My schedule is as follows:

Priority Charge and keep at 100% from 07:00 to 18:00.

AC charge from 16:00 to 07:00 to keep battery at 85%

Discharge battery (when eskom is on) from 18:05 to 06:55 until it reached 85%
 

Two scenarios happen:

1. During the day, I don’t allow battery discharge and the battery would be topped up from eskom or solar every few hours.

2. During at night, after the battery has discharged to 85% the settings wont allow it to discharge further while eskom is on. Its charge would drop to 84%, 83% etc until it reaches 80% where eskom will keep it at 80% until the morning.

So my QUESTION, is this normal? Does a battery have losses like this even while on idle due to some idle usages that doesn’t show on monitoring? 
 

I have a Luxpowertek 5kwh inverter.

You don't NEED 2 - you can work with 1 but it limits how much you can draw (to 2.4kw). 2 is better as it gives you the full 5kw draw.

Hi Mzezman

Need to do more home work are, all 5.12Kva batteries limited to a 2.4kw draw?

An alternative option would be a Revov

No Not all - it depends on the battery manufacturer. The usual Dyness, Pylontech (and others) are 0.5C so limited to max 50% output. You then get 1C batteries (Revov, Greenrich, Hubble) that allow you the full output
