I just found that my battery low light is flashing on my MPii
even though i still have 33%soc and 52v available.
What setting is responsible for this?
Also i have 6 batteries 7kwh each, connected in parallel, but they seem to be discharging at slightly different rates.
When i put my current clamp meter on each positive cable from each battery, it reads around 2A per battery at 1000w load , but that ranges from 1.8A on one battery to 2.3A on another and anything in-between for the other batteries. The cable lengths sre all exactly the same. Any ideas ?
Are they all daisy chained or connected individually up to a bus bar? Internal resistance also has a huge part to play
Are they can connected?
Is the system and ESS one? There are a few settings that affect that warning?
Hi , do you have a picture of your System or DC fuses and breakers?
Some fuse breakers reduce powers due to temprature protection and stop power but you can not see that the switch is in off mode !
I had this.
What batteries are you using?
In my case (using a 16-cell ‘48V’ LFP battery) it turns out the reason is the ‘dynamic cut-off’ response curve set up by the ESS assistant. That defaults to a low battery warning level of 52V at low discharge rates. In my case that is typically reached when the SOC gets to 20%, so it’s not helpful. The curve can be adjusted in VE Configure, under the ESS Assistant settings.

Please send screenshots of each tab of VE Configure and assistant summary, or the rvsc config file. My suspicion is you have set the low voltage alarm voltages too low.
