Hi 
get the message Low battery voltages but my batteries is almost full charged what can be ? I have a Victron Gel 220A 48 V system . System is working but on remote console I se the rd light flushing but but everything is working and battery is 98% .Do you have any idea what can be ?
These warnings are coming from the 'DC Input Low Pre-alarm' settings in the Multi. May be set too high, and triggering from spikes in peak load (which you may not be able to see in VRM or even Connect if they're very short).
If your GELS are cold they won't hold up V very well under load. My own Multi with fla batts is set to 42V to avoid these alarms in winter.
Hi thanks for your answer I have my dc input low pre alar at 43,60 is that god or not ? And my input low shut down at 37,20 so what do you think ?
Up to you. I know the reason for mine (an ac water pump starting) so I'm not concerned. If I needed to go lower than 42V I would. VRM can provide emailed alarms on things like SOC, so you could consider that.
The 37.2V trip point is Victron default and won't go any lower. If that happens maybe new batts needed.. :)
Low Battery Temp on Pb batts really does make it worse, and I don't usually have issues outside deep winter. And there's no snow where I live..
The battery voltage at 49 volts looks like it's not full. Read up on how voltage compairs to soc see the graph atrached. Currently your real soc is around 10% LiFe04-soc-voltage-chart.jpg
I get them too, I'm running beta releases.
I must be a mistake since battery is rated to go down 43.5
and the lowest point was 47.11V.
