Solar LED Street Light
The controller is an automatic control device used in solar power generation systems to manage the charging of multiple solar battery arrays and to supply power from the batteries to the loads of solar inverters. Now, I will give you a detailed introduction to the
Solar LED Street Light Controller
and its charging methods:
1. Boost Charging:
When the solar battery reaches the set value for boost voltage, the Solar LED street light controller continuously adjusts the charging current to maintain the battery voltage at the boost voltage set point. This prevents the battery from overheating and avoids gas generation. The battery maintains the boost charging phase for a cumulative period of 120 minutes, after which it transitions to the float charging phase.
2. Float Charging:
When boost charging is complete, the Solar LED street light controller enters the float control phase. When the battery is fully charged, no further electrochemical reactions occur, and all charging current is converted into heat and gas emissions. During the float phase, charging occurs at a lower voltage and current, which helps reduce battery temperature and gas emissions while providing a minimal charging current.
The goal of float charging is to compensate for energy loss due to the battery’s self-discharge and small system load, while also maintaining the battery’s stored energy at full capacity. During the float phase, the load can continue to draw power from the battery. If the system load exceeds the solar charging current, the Solar LED street light controller will no longer be able to maintain the battery voltage at the float set value. If the battery voltage drops below the recovery set value for boost charging, the controller will exit the float phase and return to the fast charging phase.
3. Equalization Charging:
Certain types of batteries benefit from regular equalization charging, which stirs the electrolyte and balances battery voltage, completing chemical reactions. Equalization charging raises the battery voltage above the standard float voltage, causing the electrolyte to gasify.
