Most common (24V) 60-cell solar panels have a Vmp of 32V to 36V - While this is higher than the battery charging voltage of around 28V, the problem occurs on a very hot day when the panel temperature increases and the panel Vmp can drop by up to 6V. This large voltage drop can result in the solar voltage dropping below the battery charge voltage, thus

Unless the cells have been resting for several minutes their instantaneous voltage will be highly influenced by charge or discharge rate. For example, my cells can be charging at (say) 20A and hit 3.4V, but as soon as the software kicks in and reduces that rate to (say) 5A, the max cell voltage will drop to something like 3.85V. Similarly a
A battery is an electrical component that is designed to store electrical charge (or in other words - electric current) within it. Whenever a load is connected to the battery, it draws current from the battery, resulting in battery discharge. Battery discharge could be understood to be a phenomenon in which the battery gets depleted of its charge.

Re-scheduling of charging/discharging If the actual net load is out of the intervals due to PV generation forecast with a large forecast error, the balance of supply and demand cannot be maintained as far as the BESS charges or discharges according to the day-ahead schedule.
By ‘generation schedule,’ we are referring to the one-day schedule of the target total outputs of the nuclear, hydroelectric and thermal power plants. The target output Vʹj at time j is given by (2), where we consider the balance between supply and demand, which includes the charging/discharging of the BESS. (2)
Thus the generation schedule of the conventional power plants and the charge/discharge schedule are determined in advance of the day-ahead UC. By ‘generation schedule,’ we are referring to the one-day schedule of the target total outputs of the nuclear, hydroelectric and thermal power plants.
