When the battery voltage drops below the specified LBCO level, the inverter shuts off, safeguarding the batteries from potential damage and preserving their lifespan. This protective measure is

It is perfectly normal/acceptable for the battery voltage to sag by 0.5 to 0.7 V under heavy load. As you observed, a good battery will recover in voltage when allowed to rest.

When the battery voltage drops below a certain threshold, the inverter stops functioning to prevent battery damage. Typically, the cutoff voltage for most inverters is between 10.5 and 12 volts.

Please check the individual voltage of each battery using a multimeter - they should all be close to 12.8V when fully charged. If any battery is more than 0.5V higher or lower than the other

When the battery voltage falls beyond a certain low voltage threshold, the base current of T2 becomes sufficiently low such that it''s no longer able to hold the relay into conduction and

The graph below shows the default ''Discharge'' vs. ''DC input low shut-down voltage'' curves for different battery types. The curve can be adjusted in the assistant.

In a ESS application there is a min SOC setting which stops the inverters discharging when batteries reach desired low level. Works well.

A battery voltage meter is a handy tool to directly measure the voltage of your inverter battery. A fully charged 12-volt battery typically reads around 12.6 to 12.8 volts. As the battery

If your inverter battery voltage is too low (below the recommended range), it indicates that the battery is undercharged or has a problem. This can lead to power failure when you need it most.

Measure its voltage output using a multimeter to ensure it is within the recommended range. If the reading is below the recommended level, it''s time to replace the battery.
