Thank you, so yes must just make sure that my dad, he was the one who did it, does not have so many heating elements on.

If I flipped the changeover switch to eskom before turning on the aircon, then this would mean that it is bypassing the inverter and it would not cause an overload?

Hi, I had another question, There was no loadshedding or anything, we had power coming in from Eskom. With two computers on, a heater, a food warmer, everything was fine. But then the aircon was turned on without my knowledge and straight away it tripped the inverter. I had to to turn the inverter off and then on again. I understand that the overall wattage usage is too high and it caused it. I flipped the changeover switch to Eskom and then turned the inverter off and on. Is this normal that the inverter struggles with a high load even when there is power coming in from Eskom?

Hi, So I had the voltage checked: 13.1 and 13.2. I then did a test with a gaming computer and 65 inch tv on: Computer and TV on 234 input and output Power turned off at 10:36 Input 228 Battery displays 3/4 cells 12:36 - 2 hours later Battery displays 3/4 cells 13:10 If I turn a light on, it drops to 2 bars with bar 3 flashing. Light turned off straight away, went back to 3/4 cells. 13:36 - 3 hours later 2 cells remaining Power turned back on 3 hours of loadshedding tested.

Hi, you are right I don't think its compatible, I have someone coming to install something on DB board and he will test the voltage for me.

Assuming the battery tester I have works for Lithium batteries, does this look right? Is my one battery just needing a good charge that the score is so low?

Hi, thanks so much for your help! Yes I already have that installed. I have this Konnwei BK100 Wireless BT Car battery tester 100-2000 CCA 6V 12V - https://www.autosupply.co.za/product/konnwei-bk100-wireless-bt-car-battery-tester-100-2000-cca-6v-12v-bte-bk100/ - Though this I used to test my gel batteries, not sure if I can test Lithium with it. I think I must let it charge for longer before I test it, I did earlier after only 4 hours of charging but it said something was odd about the voltage.

I changed program 05 to USE when I changed the settings above. Program 02 is SOA Program 11 is 30A The highest I could set cut off to is 24, is this ok?

Hi, I don't have solar, no I did not fully charge the batteries, they were just installed on 20th of June but the power has not gone off since they were installed. The settings were not changed before, I just changed the following settings now to match the info I was given with the batteries: Bulk: 14.4v - 28.2 Float: 13.6v ( 13.5v for Must 1kva Inverter ) - 27.2 Cut Off: 11.2v - 22.4

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
