When the battery is almost full, the battery voltage will be slightly higher than the inverter/charger''s DC voltage. This is the "cue" for the inverter/charger to reduce this "overvoltage". It does this by feeding power into the grid. In a 48V system, this overvoltage is set at 0.4V, and in a 24V system, this is 0.2V.

The low DC cut-off voltage for lithium-ion batteries is typically set between 2.5V and 3.0V per cell. This range helps prevent over-discharge, which can lead to irreversible damage and reduced battery lifespan. For a standard 12V lithium-ion battery pack, this translates to a cut-off voltage of approximately 10.5V to 12.0V.
What would be a "happy medium" low DC cut-off voltage, given that battery life is shortened when allowed to drain to very low levels? I have seen a 48V model default setting of 42.0V. This appears to be low. One would like to think that you are operating within safe limits to not be penny wise by shortening the life of an expensive battery by ...

The bottom line is that "DC" and "AC" are no longer exact equivalents for "direct current" and "alternating current"; DC refers in a general way to quantities that don''t regularly change polarity or that have very low frequency, and AC refers in a general way to quantities that regularly change polarity at a frequency that is not "very low" in the context of a given system.
DC power is widely used in applications such as telecom, automotive, aircraft and other low-voltage, low-current applications. In a DC power system, the uninterruptible power system (UPS) takes in primary power — usually utility AC — and outputs DC voltage while providing backup power from the integrated batteries in the event of an ...
