Water Mill Generator Controller Lithium Battery
Off-Grid PWM Hydroelectric Generator Controller
FKJ-B model Off Grid PWM Hydroelectric Generator Controller Product Characteristics
◆The product is manufactured according the JB/T6939.1-2004 industrial standard and GB/T 19115.1-2003 national standard also with users’ technical requirements.
◆Big LCD display. The images tell working state visually. Various data show: real-time generator voltage, current, power; battery group voltage, charge current.(The main board is with button battery, in case of power failure, history data can be saved for 30 days)
◆Two sets of control systems：PWM constant voltage system and three-phase dump load system.
◆When the battery disconnect or damage, the three-phase dump load will start automatically to avoid the gengerator idling and runaway accident.
◆The protection function of battery: polarity reverse protection, disconnection and damage protection.
◆Over-charging protection of the battery: When the battery is full (the battery voltage getting 125% of the rated voltage), the controller will carry out three-phase dump load automatically to stop charging the battery.
◆Auto recharging of battery: When the battery voltage reduces to 108% of the rated voltage, it stops three-phase dump load to recharge battery automatically.
◆The controller is equipped with manual three-phase dump load switch. To using this switch, the wind turbine will carry out three-phase dump load forcibly.
◆The controller is equipped with surge arrester.
※ Solar panel control system is optional. Based on customers' requirement.
※ Disel generator port is optional. Control the generator start and stop automatically
※ Adopt Modbus Communication protocol. Convenient to carry out the secondary development.
※ Adjusting the technical specification via RS485 is available. Convenient to adjust the different wind turbines for professional customers.
※ Support WIFI and GPRS. Customers can monitor the real-time working state of the generator system via PC and mobile and query history working sate. Both Android and OS are compatible in Mobile.
