Thats why I am here, to learn, anyhow I set Bulk charging to 56.8 Float Charging to 55.2 If anyone think this is not right please let me know.

One thing @zsde this are not Lead Acid but Gel batteries. I mean not sure does it matter but just wanted to point that out. Thanks again .

Hi @zsde tnx for answer, I found this little book on the battery

Hi guys, first of all I love this forum and reading it last few days in order to learn as much as I can but still I am failing to understand what should be charging voltage of my system, I have 5KW inverter https://voltronicpower.com/en-US/Product/Detail/Axpert-MKS-1KVA-5KVA I also have 4 of there Exide batteries https://www.supac.co.uk/product/9004108/exide-gel-es2400 Only thing I was able to find regarding them is https://unimar.hr/Documents/product_manual/1240803_3_1.pdf where it says constant voltage should be 14.1 If you can share the what would be your recommended charging voltages it would be really helpful This is my current setup Bulk charging voltage: 57v Float charging: 54.4 Battery cut off: 46v Battery equalization is off Thanks
