摘要
在太阳能光伏发电系统中,控制器占据着极其重要的位置。控制器在充电启动时刻根据电池状态决定充电模式,若电池处于过放状态就进入提升充电模式;若电池处于欠压状态就进入直充模式;若电池处于浮充状态就进入浮充模式;若电池本身超压则继续停留在超压报警状态。当完成提升或者直充后,控制器转入浮充状态,当电池电压由于负载用电而下降到低于直充返回点时,控制器重新转入直充状态。此时,若负载继续用电且太阳能电池板无法提供足够的充电能量导致蓄电池电压继续下降到欠压甚至过放点以下,控制器就进入过放保护,关闭负载并转入提升充电状态。

In the solar photovoltaic power generation system,controller occupies an important recharge mode depends on battery the moment the controller starts to becharge. In the solar photovoltaic power generation system,controller occupies an important recharge mode depends on battery the moment the controller starts to be the battery is in over-discharge state,the controller will start its charge enhancing mode;If the battery is in undervoltage state ,the controller will start its direct charge mode;If the battery is in float state,the controller will start its float mode;if the battery itself is in overvoltage state,the controller will stay at the alarming state. When the controller pleted the charge enhancing progress and direct charge progress,it then starts its float state .When battery voltage fall to belower the direct charge return point,the controller will turn into direct charge state. At the moment,if the loads continue to consume battery power,and solar solar panel can not provide enough charge energy leading to storage battery voltage continue to fall to undervoltage stat
