hi guys, my system is behaving strangely...thw bmv 700 shows 89%, but the inverter keeps showing low battery alarms and keeps switching on/off. am not on ESS..firmware 2620159...easysolar 48/3000/35....help
asked
low voltage on inverter while bmv shows 90% battery
And what voltage reading do you have at this moment(BMV and inverter)?
What is the setting for the low voltage cut-off?
thanks for the prompt response
bmv shows a voltage of 39.9v(89% battery) with load on...without load the voltalge(multiplus off) shows 49.96v
low voltage cut-off is the default havent changed it...its around 43v, if I can remember
Is my battery bank (ceil nxt 12v/200ah x 4) dead?
What load do you running? 40V is pretty low for a 48V system.
The default low voltage cut-off for a 48V Multi is 37.2V and if you never changed that this can be a reason for your dead batteries now.
i have the battery bank now for 2yrs with minor use..the highest dod ever is 32%(SOC 68%)...electricity is quite reliable here. Float voltage is 54.8v, absorption is 58.8v....has been charging without any issues
current bmv is 50.89v, inverter is off...if switched on, it switches off immediately after showing low battery alarm
hi guys, have noted the following behaviour with my battery bank
from fully charged(100%) to around 91%..the voltage drop is gradual and matches the load very well...then it starts leaps of doom...at 90% it shows 46.34v, at 89% it shows 39.72v and it switches off at 88.8% with 37.2v...
is my battery bank gone beyond any hope?
I have been using adaptive+battery safe charging for my nxt ceil agm battery with float voltage of 54.80v and absorption of 58.80v...what did I do wrong so as not repeat again?
