Mark Posted September 19, 2015 Share Posted September 19, 2015 Hi All Just wanting to check my settings with other Axpert Users: I have the following: Axpert 5Kv 48V 200 ah bank - 2x 48V banks (12 x 4 102ah Lead Acid Batteries each) 2x 300W panels I have following settings: 1 SOL 2 20A 12 48V (default feels to low for me) 13 FUL (don't know what this voltage equates to ???) 16 CSO 26 57.6V (Bulk voltage) 27 54 (Float voltage) 31 Sbe When I want to equalise the bank I then change 26 from 57.6 to 58.4 (the highest I can go???) Your thoughts please... Regards Mark Quote Link to comment Share on other sites More sharing options...
Mark Posted October 7, 2015 Author Share Posted October 7, 2015 Hi All I realise everyone is busy but am keen to get the thoughts of other Axpert users??? Thanks Mark Quote Link to comment Share on other sites More sharing options...
edmundp Posted October 7, 2015 Share Posted October 7, 2015 Seems fine depending on load? What are you doing with it? Quote Link to comment Share on other sites More sharing options...
Mark Posted October 7, 2015 Author Share Posted October 7, 2015 Very little load. More keen to understand other users equalisation process and settings... how do you go about it... Quote Link to comment Share on other sites More sharing options...
edmundp Posted October 7, 2015 Share Posted October 7, 2015 What type batteries are you using? Most sla types do not require equalisation. But if you do just set the voltage as required when doing a once off equalisation. Quote Link to comment Share on other sites More sharing options...

But if you do just set the voltage as required when doing a once off equalisation. I have Lead Calcium 102 ah deep cycle batteries so would like a higher equalisation but use the Axpert Max of 58.4V setting for a charge cycle around the end of each month.

edmundp Posted October 8, 2015 Share Posted October 8, 2015 Ok. Does your spec sheet stipulate a particular equalization voltage and time? Quote Link to comment Share on other sites More sharing options...
Mark Posted October 8, 2015 Author Share Posted October 8, 2015 Ok. Does your spec sheet stipulate a particular equalization voltage and time? No... thats the issue... I think I am close except for the upper limit on the Axpert voltage to 58.4... Regards Mark Quote Link to comment Share on other sites More sharing options...
Chris Hobson Posted October 10, 2015 Share Posted October 10, 2015 Hi Mark I have had a look at your photos again and it looks like your batteries are SLA (sealed-lead acid). In which case you should NOT be applying an equalisation charge. Zeners and battery balancers I am afraid. Quote Link to comment Share on other sites More sharing options...
edmundp Posted October 10, 2015 Share Posted October 10, 2015 Agreed. Chris Hobson 1 Quote Link to comment Share on other sites More sharing options...
