When does a solar battery charge & discharge?
The battery will only* charge when the solar is producing more energy than the loads are consuming. The battery will only* discharge when the loads are consuming from the grid. When the battery charge falls below the minimum allowable SOC set by the BMS, the battery will be force charged from the grid until the SOC reaches the minimum.
When does a battery discharge?
The battery will only normally discharge when the energy meter senses power coming from the grid (and there is charge available in the battery). In the normal operation of electrical appliances, they will be switched on and off by the end user, or in the case of heating and cooling, a thermostat will control loads on and off.
What percentage of a battery should be discharged?
Shallow Discharge: Using only 20–30% of the battery’s capacity. Deep Discharge: Using 80–100% of the battery’s capacity. Deeper discharges can shorten the battery’s lifespan. For example, a battery cycled at 80% DoD may last only 500 cycles, while the same battery cycled at 20% DoD could last 2000 cycles.
Do high discharge rates affect battery life?
High discharge rates are essential for power-hungry devices like drones or RC cars. However, consistently discharging at high rates can reduce the battery’s lifespan. Pro Tip: Match the battery’s discharge rate to your device’s power requirements to avoid overloading the battery. Part 5.
What if a power supply is uncharged?
One other major concern is the over-current of the power supply during initial turn-on. An uncharged output capacitance would appear to the power supply control circuit as a dead short across the output. The power supply would most likely fail to establish a 12-V output when initially turned on. 3.
What happens if an AC-DC power supply is interrupted?
An ac-dc power supply’s input voltage can be interrupted during circumstances such as a brown out condition or a brief power failure. When this happens, the dc output will only remain within regulation for a short period of time. The time period is specified on the power supply datasheet as the hold-up time.

Why capacitor is discharging quickly | Forum for Electronics
That looks right to me. When the pulse is low, the transistor is not conducting so the capacitor quickly charges to 12V through R1. During the pulse period, the transistor turns fully on and the voltage across the capacitor will drop due to the potential divider of R1 and R3 plus a residual C-E voltage in the transistor.
