Controller
The solar system can quickly and real-time collect the current working status of the photovoltaic system to obtain
the work information of the
PV
station at any time, and can also accumulate detailed historical data for evaluating the rationality of the
PV
system design and verifying the reliability of the system components.
What protection modes are there for solar controllers?
Mode 1: Direct Charge Protection Point Voltage
Direct charging, also known as quick charging, typically uses high current and relatively high voltage to charge the battery when the battery voltage is low. However, there is a control point, also called the protection point. The direct charging protection point voltage is usually the “overcharge protection point” voltage, meaning the terminal voltage of the battery should not exceed this protection point during charging; otherwise, overcharging will harm the battery.
Mode 2: Equal Charging Control Point Voltage
After direct charging, the battery is generally left by the charge and discharge controller for a period, allowing its voltage to naturally drop. When it drops to the “recovery voltage,” it will enter equal charging state. Equal charging means “balanced charging.” The duration of equal charging should not be too long, generally only a few minutes to a dozen minutes. Setting the time too long can be harmful. For small systems equipped with one or two batteries, equal charging is not significant. Therefore,
solar street light controllers
typically do not set equal charging, having only two phases.
Mode 3: Charge Control Point Voltage
Typically, after equal charging is completed, the battery is also left for a period to allow its voltage to naturally drop. When it reaches the maintenance voltage point, it enters floating charging state. This is similar to small current charging, where the battery charges a little whenever the voltage drops, preventing the battery temperature from continuously rising, which is beneficial for the battery.
Mode 4: Over-discharge Protection Termination Voltage
The discharging voltage of the battery cannot fall below the national standard value. Although battery manufacturers also have their own protection parameters.
Generally, for a 12V battery, the over-discharge protection point voltage is artificially added
0.3V
as temperature compensation or zero drift correction for the control circuit. Therefore, the over-discharge protection point voltage for a
12V
battery will be
11.10V
and for a
24V
system, the over-discharge protection point voltage will be
22.20V
