We have a Smart LiFePO4 25,6V/200Ah battery connected to a Multiplus Compact 24V/2000VA Inverter.
When i turn the Inverter on, or set it to "charge only", nothing happens. When i then connect it to the mains, the alarm LED comes fully on (not flashing). None of the other LEDs are lit.
Unfourtunately, the battery have been unmanaged for too long, and im afraid it has been discharged below the normal operating voltages.
Is this a correct assumption?
assuming this is the case, and it is still possible to recover it, is the multiplus charger able to recover a battery that has been over-discharged? Or is a 3rd party charger needed?
BR,
Steffen
