How to Battery Protect against Low Discharge with Inverter

The battery protect is unidirectional. Meaning is cannot charge and discharge through it. What you can do is set the inverter to switch off on battery voltage and SOC. Set your system to shut off around 10% SOC min to allow for cell imbalances at lower soc. The victron 12v charger should wake up the other battery.

How to Choose the Right Low Voltage Battery Cutoff (LVC)

This means the LVC will disconnect the battery from the Load when the voltage drops to 10.8V. For the lithium battery, this cutoff is at higher voltages as the Lithium battery LifePo4 has a voltage of 12.8 Volts, so the cutoff voltage for a Low battery is 11.2 Volts. This voltage keeps the Lithium battery safe because the BMS inside the …

Inverter shuts down with "low battery" at 12.6 VDC

The fridge was pulling 31 amps continuously and after about 30 min the inverter flashed a "Low Battery" warning and shut it''s self down. So I checked the BMV and it said the voltage on the batteries was sitting about 12.6 V. So I repeated the steps and did it again and the same results happened. This time it shut down around 12.5 V.

Inverter Low Voltage Cutoff--Why SO low?

Yes the lead acid is getting pulled down 1.0 to 1.5 of voltage sag at 160 amps so the cut off is a bit low to prevent premature disconnect. Battery will recover voltage when the load is dropped. Need to manage things manually or get a monitor. The cut off on the inverter is not there to save the battery from itself.

Inverter low voltage protection shutdown

Activity points. 15,026. Most lightweight inverters first convert the low voltage to a DC high voltage (isolated). For a "true sine wave" it should be around 350VDC as the peak of 230VAC is about 325V. This voltage feeds a full bridge (at least 4 power switches required) and this full bridge is PWM modulated with about 20 kHz or higher.
