Growatt SPF5000ES and Dyness A48100 Settings (No Solar)

Good day, I recently installed the above set up and would like some advice on the current settings which are reflecting on the invertor.

Setting 03 AC Input Voltage Range - UPS

Setting 12 Voltage point back to utility source - 46%

Setting 13 Voltage point back to battery mode - 95%

Would the above be correct/recommended?

Additionally, I noticed my battery continuously discharges and recharges from 100% to 95% , then back to 100%. Takes about 6 hours to discharge to 95%, then about 15 min to get back to 100%. Is this normal and has anything to do with setting 13 by any chance?

Appreciate any assistance. Thanks

I think setting 03 is fine because it(UPS) allows a voltage range of 170-280V.

I personally set the Voltage point back to utility on 65%. In as much as you want to utilise the stored power, you must leave some for load shedding.

Thanks. After my post I understood that settings 12 and 13 don't really matter for me as I have no solar currently. System is only for loadshedding
