    FAQs about The voltage of the battery bank in the power plant is too low

    What if a battery is under load?

    Using nominal system values while under load guarantees the batteries won't be drawn below 50%, but there can be a margin for lower Voltage; when the load is removed the Voltage 'springs back up' and could then be above 48 Volts resting, meaning the battery is still above 50% (although just barely).

    What if battery voltage is too low?

    Check the battery voltage, if the battery voltage is too low ( lower than 24v for 3k, and lower than 48v for 5K.), charge the battery in time. If still problem, go to steps 3. Step 3. Disconnect all power source,and open the top cover, take out the main board, place the main board on the insulated tables.

    Why does battery voltage drop with load?

    The greater this (non-load) internal resistance the more the battery connection voltage will drop with as load increases. It's more common with lead acid batteries to see larger voltage drop with load as they have a higher internal resistance than lithium chemistry batteries.

    Why does a battery charge voltage increase after a repair?
