I don't have vanilla firmware so I cannot check. @Coulomb you have those facts at you fingertips. Sadly, no, and for reasons that escape me at present, I can't find where the battery low warning is triggered. It seems that setting 12 isn't involved. What you are possibly thinking of is that the batter low setting can affect when to recharge the battery, replacing setting 12 if it (the battery low setting) is higher. 2 hours ago, Chris Hobson said: If you are using vanilla firmware you may have charging stop prematurely. @Coulomband @weber have collaborated and produced Aussie firmware that eliminates the charging bug. Yes, please check out the patched firmware. As well as fixing the two premature float bugs, it also changes the thresholds for the battery low warning. Instead of being 2.0 V above the battery cutoff setting, it becomes 0.5 V above. Similarly, turning off the battery low warning occurs at the cutoff setting plus 1.0 V, instead of the factory firmware's cutoff setting plus 4.0 V. These figures are more LiFePO₄ friendly, and only happen with the LiFePO₄ version of the patched firmware. Quote I do not know if they have firmware for your model of inverter. Hence my previous post where I ask about the exact inverter model.
December 31, 20187 yr Author 5kva and 48 Volt And sorry, my mistake, it says Voltex MKS 5KVA. I mistakenly thought it was Axpert.
December 31, 20187 yr Author Where can I find a certified installer in the Rustenburg area who knows how this thing works and can set it up properly. I live 200km away and cannot afford for the inverter to switch off the moment I Leave the farm. Or should I rather invest in a different unit with a separate charge controller.? I am a novice at solar usage and need a solution that works well.

It will hopefully be manufactured by Voltronic Power, who call them Axperts. Unfortunately, this still doesn't make it clear whether it's 5 kW or 4 kW, and whether you got the 64 V option or not. A quick web search indicates (but not conclusively) that you probably have a 5 kW model without the 64 V option. That's the bad combination, for which there is no patched firmware. A photo of the label on the side will make it easy to identify.

December 31, 20187 yr Ok. I think you can install @weber and @Coulomb firmware. Moreover, we saw yesterday battery voltage was low. Is it a sunny day now? What´s the voltage and current now?
December 31, 20187 yr This is voltage range for Pylon: Discharge Voltage V 45 ~ 54 Untill you install de new firmware, you can set 29 to 45.5-46.0 V.

January 1, 20197 yr 18 hours ago, JohanO said: Max is 64v That's odd. I was expecting "(64V") in the model name if it goes to 64 V, like this: [ Edit: the above is from a colleague's machine. ] But I guess it's up to the reseller. So now, when people ask whether it is safe to update their software, I recommend that they instead post an image if their main firmware (U1) information screen, like this: That was mine, from three years ago, as it came from the factory. Sorry to muck you about, but this is too important to leave to chance. Could you please verify, text or photo is fine. [ Edit: Sigh! Even this doesn't seem to be enough to distinguish different firmware versions, since there are at least two very different versions 71.20 in existence, and there may be 52.XX overlaps as well. So I'm considering how to definitively solve the "can I update my inverter and if so to what" question. ] Edited January 1, 20197 yr by Coulomb

January 1, 20197 yr Geannie is working again... You asked for addding a new LFP battery, but I think in your case, It would be better to add other 6 solar pannels... Can you answer this? If LFP is fully charged at 18.00, is It enough for the night? Edited January 1, 20197 yr by Javi Martínez
