Hello. Im from New Zealand and lately like today with loads of sun my battery voltage reads 0.01 as per screenshot.
I have 380W panel
2 100 amp Lithium Batterys
The battery app i have says 1 is at 72% and the other is 75%
asked
Smartsolar mppt 100/50. Min battery voltage reading 0
Isn't the mppt smart solar suppose to power on when solar panel is off and i turned the breaker off and the mppt wont turn on untill i turn the breaker back on ????
This is what each battery is sitting at and still the victron wont charge.
Voltages are fine, but no current.The min voltage comes from when the system was first turned on. Can be ignored.
Looks as if it's seeing the battery as full because battery voltage is 14.2V.
Your battery supplier should have given you voltage setting for charging. Adjust absorption and float voltage to match these.
But i have not turned this off since i first installed it 31 days ago and it does this out off the blue during the day. Sets the battery voltage to 0 and then no solar come in or the yield just says 0 as you can see.
I selected the correct settings in regards to absorption and float.
Is it a faulty unit?
As the other day even thou the battery was full the daily yield was still increasing ?
As you can see a couple of days ago for 2 days was reading 0 volts on the battery ????
This is the 2 batteries I have,
Sorry to bomb bard with all the questions but are you able to provide charging settings etc as I am new to this :(
Check the wiring and fuses between the MPPT and the battery.
0V battery voltage is most likely a a bad connection or blown fuse.
Thank you, I was going to pull everything apart and check the wires tomorrow but thought may be a prob with the unit.
Will update when i find anything
Maybe that BMS disconnects the battery.
Bms is fine.
Crisis averted it was a fuse ...the resettable switch had worked itself loose from charge controller to the battery.
So time to get different fuses.
Installed a victron shunt while i was checking so more peace of mind on what SOC the batteries are at.
Thank you all.
