在可再生能源系统中，为了确保连续生产，每当充电源是太阳能、风能或水力时，总是需要与充电控制器相关联的电池。对于光伏（PV）系统，在强烈的阳光峰值条件下由太阳能电池产生的过量能量可能损坏电池。因此，充电控制器用于保持电池的适当充电电压，使得当来自PV模块的输入电压升高时，充电控制器调节该过程，从而防止任何过度充电。本文提出了一个实用的解决方案，离网光伏系统使用标准的商业元素。基于电池充电控制的实验结果进行了详细的分析，从而使自主存储和生产系统具有长寿命和高安全性。实验工作是用175 Wp光伏组件对24 V-55 Ah太阳能电池充电，通过最大功率点跟踪/三级充电循环（MPPT/TSCC）充电控制器进行的。三阶段充电周期（TSCC）控制以及最大功率点跟踪（MPPT）的优点已被证明可以在定性和定量方面提高充电效率。
In a renewable energy system, in order to ensure continuous production, batteries associated to a charge controller are always necessary whenever the source of charging is solar, wind, or hydraulics. For photovoltaic (PV) systems, an excessive energy produced by solar cells during intense sunlight peak conditions could damage the batteries. A charge controller is therefore used to maintain the suitable charging voltage to the batteries so that, as the input voltage from the PV module rises, the charge controller regulates the process, thus, preventing any overcharging. This paper presents a practical solution for off-grid PV systems using standard commercial elements. A detailed analysis is carried out based on experimental results of the battery charge control allowing a long-life and a high safety of the autonomous storage and production systems. The experimental work was performed with a solar battery (24 V-55 Ah) charged by a 175Wp PV module, through a Maximum-Power-Point-Tracking/Three-Stage-Charging-Cycle (MPPT/TSCC) charge controller. The benefits of the Three-Stage-Charging-Cycle (TSCC) control as well as the Maximum-Power-Point-Tracking (MPPT) have been thus proven for the efficiency of the recharge, both qualitatively and quantitatively.
