【正文】 ng pulse width Narrows gradually, the average charging current decreases. When the charging voltage reaches in the electricity at ordinary times, charging pulse width goes to zero, rechargeable electric terminated. Pulse controller charging method is reasonable, high efficiency.3 controller performance characteristics put electricity protectionTo avoid excessive battery discharge, is another important power of the pv system controller. If do not pay attention to, the photovoltaic system load can run out of battery power can easily. General photovoltaic system controller has deep cycle battery protection function of excessive discharge. Controller to prevent the battery discharge measures include: (1) is reached in the charge for electricity at ordinary times, disconnect the load. (2) of a semaphore or buzzer alarm, shows that the battery voltage is too low. (3) through to a backup power supply automatically. When the battery is in a state of low charged, start the backup power supply, such as diesel generator to the battery charging. When when the battery is filled, a continuous controller disconnect backup power, photovoltaic system restart it electric storage pool charging operation. the functionCommercialization of pv system controller, its function characteristics are different, can undertake choosing according to the following controller function characteristic. (1) temperature pensation: according to environment temperature to adjust the battery charging current. (2) the load circuit breaker: when if there is any difficulty cannot satisfy the needs or replace the fuse, fuse can substitute for load. (3) low voltage alarm: when the battery charged state is lower than in the electricity at ordinary times, can hear the warning sound. (4) low voltage disconnect: when the battery to discharge in the electricity at ordinary times, cut off the load automatically. (5) the voltage indicator: analog or digital display battery voltage, indicates the charged state of storage battery. (6) current indicator: analog or digital display solar cell phalanx output current and load current. (7) ampere hour meter: digital storage battery is power or battery. (8) backup start charging control: automatically start backup power supply, recharging the battery into the line. (9) square power shunt regulator: excess phalanx charging power to bypassThe important load, such as electric water heater, e
