1. Summary Solar Power System is the power of new energy power generation system. It designed and manufactured for characteristics and requirements of new energy power generation system, suitable for solar photovoltaic power generation system for power supply equipment of high quality, high reliability requirements, system change sunlight to electricity by PV battery, through the charging circuit to charge the battery, at the same time, the battery supply power to the part of inverter which supply the AC power to the AC load. The series of control &inverter integrated power supply has wide input current voltage, rated output voltage and frequency. products used in a large number of families, substation, communication service industry or the comprehensive system of power etc, and can realize the real-time observation on line of remote data through remote communication function. It is the core of modern new energy generation system. Please read this manual carefully before use it! 1.1. Main characteristics (1) DSP chip control of high performance produced by TI company. (2) Closed loop PDI algorithm, improved the dynamic response of system output, and the quality of power output. (3) It can realize multichannel solar array input control, omit the combiner box at the front end, save the cost for user. (4) Each charge detection with return difference control function, avoid switch being into oscillatory conditions. (5) LCD display interface can real-time monitor the parameters of battery voltage, load current, temperature inside, AC output voltage, AC output current etc. (6) Multiple protection and vent recording function. (7) Statistical functions of generating capacity (8) With electric switch function which achieve OMS switching. (9) Low power display status, further reduce the loss. (10) Remote monitor and control (RS232 optional) (11) Smaller size, meet the installing requirement of indoor and outdoor. (12) Easy and fast maintenance (13) This Off-grid PV System if per day charging times average Solar Radiating is 3.5hrs/day, 7KW H/day. (Recommend load :less than 5KW H/day) The real optimized performance depends on the location and environment. 1.2. Purchase inspection (1) Solar Power System Host 1 piece (2) Manual 1 piece 3

3. Display and function instruction LCD advice the display of 128*64 lattice chart, through LCD display interface and easy operated menu to operate the system. User can browse conveniently the parameters of input, output, load and battery to obtain the current machine state and alarm information in time. 3.1. Display board Event record System set up Real time data Equipment information 3.2. LED Indicator light show (1). Photovoltaic controller is over current when light on,photovoltaic controller is in normal when light off. (2). Mains supply is normal and output is in the mode of mains supply when light on, mains supply is abnormal or output is in the inverter mode when light off. (3). Inverter is operating when light on, indicate inverter is closed when light off. (4). The battery is low voltage when light on, meanwhile, the buzzer will sound at interval of 1S. The battery voltage is normal when light off. (5). The machine is in over load state when light on, non overload when light off. (6). The machine is in status of breakdown when light on, output will switch to bypass; the machine has no breakdown currently when light off, and will restart 3 minutes after recover the breakdown unless invert shot circuit. 5
3.3. Button function (1). F1 : Long press the key to start machine ;short press the key dead the sound made by buzzer. (2). F2 : Long press the key to shut down the machine. (3). RST : Escaped key. (4).The arrow key can switch the window or move cursor in different menu. (5). OK : Confirmation key 3.4. Data display (1)Main interface Bellow is the main interface of the whole display board, can move cursor by the key of up and down, final press confirmation key-- OK to enter the next interface; and press escape key RST back to the main interface. Data Event Infor Set Real-time data Event record Equipment information System set up (2)Real time data sub interface Inverter voltage: Inverter frequency: Mains supply voltage: Mains supply frequency: PV current : Battery voltage : Inverter temperature : Temperature controller : Load capacity : Outpur current : Daily generating capacity : Fault code : Gross generation kwh Above four interface can switch display by up and down key. 6
