I hope some one can give me some advice. I have an old Axpert 5kw inverter. I have attached new lifepo4 batteries. These are DC solar energy DC-L5000/LV. I have given new parameters to the inverter. Type USE, absorb 56.6V, float 55.4V,cut off 47V, max charge current 40 amps. These settings were provided by the supplier who is now not responding to questions. This seems to work ok but I'm uncertain about the following issues. 1. When the batteries show soc of 100% they still take 30 amps with virtually no load. 2. The charge voltage never reaches 56.6V, only about 54V. I know that since there is no data link between batteries and inverter some off the readings may be inaccurate. I am using the ones displayed on the battery led display. Any ideas ?
