Ariel Posted July 13 Share Posted July 13 (edited) Hi there, I have an inverter that was running with gel batteries and recently installed lithium batteries, about a month back. We recently had a fault in the road that caused loss of power, my inverter kicked in while we were sleeping but died, not sure when. The power came back on and was charging the batteries for at least 4 hours, yet when I did a test but killing the power to the mains, the inverter was beeping as it seemed like the batteries were low. So I don't think they are charging and now I think I must change the settings on the inverter, as its set to default. I have now set the following after doing some research: Bulk: 14.4v - 28.2 Float: 13.6v ( 13.5v for Must 1kva Inverter ) - 27.2 Cut Off: 11.2v - 22.4 This is what I have: GeeWiz Axpert 3000VA (3000W) PURE Sine Wave SOLAR Inverter - 50A/1200W PWM (Hybrid) GeeWiz 12100L 1.2kWh 12V 100Ah Lithium Ion LiFePO4 5000 Cycle Battery (FIRST LIFE CELLS) - 3 Year Unlimited Cycles Warranty - 5000 Cycles X 2 12.8V 1.2KWh Rating: 1C Maximum continuous discharge: 100Amp Cells: 1st life prismatic LiFePO4 Series: 2, 3 or 4 batteries Parallel: 4 Batteries Communication: None >5000 cycles at 80% DOD 3 Year Unlimited Cycles Warranty A balancer will be required when using these in series This battery has been built with cells that are designed for 5000 cycles (and comes with a 3 year warranty) Battery Voltages Bulk: 14.4v Float: 13.6v ( 13.5v for Must 1kva Inverter ) Cut Off: 11.2v Specifications 12.8V 1.2KWh Rating: 1C Maximum continuous discharge: 100Amp Cells: 1st life prismatic LiFePO4 Series: 2, 3 or 4 batteries Parallel: 4 Batteries Communication: None >5000 cycles at 80% DOD 3 Year Unlimited Cycles Warranty Features High Cycle Life and Service Life High Performance Lithium battery Internal Battery Management System Excellent high temperature performance High energy density and conversion efficiency Can be configured in 12V, 24V, 36V or 48V in series Easy drop in replacement for old lead acid battery installs BMS protects internal cells and ensures smooth operation Compatible with most UPS & Inverters using AGM/VRLA charge setting Built-in protection for over-charge, over-discharge & over-temperature External cell balancer required when placing in series to ensure balancing Perfect replacement Lithium solution for upgrading your lead acid installation Thank you Edited July 13 by Ariel Quote Link to comment Share on other sites More sharing options...
