Tablet PC & Acc. NEW 300W GRID TIE INVERTER FOR SOLAR PANEL Over Current Protection. Pure Sine Wave Output. Fed the power to city net. No battery for solar systme anymore, really enviroment friendly. Wide range input voltage 10.5-28V 300W. Max power point tracking function. Please be noted: this solar grid tie inverter only work with solar panel, can not work with wind generator. Work as off grid inverter. Directly connected to the solar panels (do not need to connect the battery) Using precise MPPT function, APL functions, the inverter automatically adjust the solar panels of maximum output power? Simply connect the solar panel to the grid inverters. Do not need to connect the battery. AC 0 angle with high precision auto-detection AC phase angle of 0 through isolation amplifier then input to the MCU for high-precision detection and analysis. The phase shift rate is less than 1%, thus achieve high-precision with phase modulation AC output together. Synchronous High-frequency Modulation In the process of the grid, usually adapt the same phase angle in parallel. Ie, When the two-phase alternating current total is equal to 0. Use switch to combination the two AC fusion and the product is rectified AC half-frequency AC to 100Hz first, then the machine use the high frequency current in the circuit and semi-100Hz frequency alternating current generated combination, to achieve high-frequency modulation. Pure Sine Wave Output Use SPWM directly to make pure sine wave output. Automatic Sensing Function Solar Luminosity Use the latest luminosity perception operation technology. The different illuminate angle and intensity of the solar panel will produce different current output. Use advanced CPU to operate the different illuminance and the data can be directly displayed on the LCD. Then you can visually see the sense of the strength of the sun unit. Power Automatically Locked (APL) In different current fluctuations, we should use the MPPT function. When the MPPT function adjusted to the maximum power point, the product automatically powers locked in maximum power point, then made the output power more stable. Maximum Power Point Tracking (MPPT) Because the current intensity and the voltage changes at any time, if there is no power point tracking, there will be a lot of problems. In the past time, usually adopt a solar controller, but this product uses high-precision MPPT operation power, automatic and immediate adjust the solar panels output power at the maximum output point, then achieve a stable output purposes. Automatically Adapt To Different Load Power Factor Adapt to any of the power load. Constant Current, Constant Power This product is constant current, constant output power, without any overload, over-current phenomenon. Automatically Shut Down When The Power Output Of a Fault When the city power system is in failure, the inverter will automatically turn off the output. Stack Multiple Machines Multiple small power inverters in parallel can achieve large output power. High-Frequency High Conversion Rate Adapt high frequency converter, the output more efficient. Recommend use solar panels. DC Maximum Input Power. Maximum output power factor. AC maximum output power. AC standard voltage range. Output short circuit protection. 099%(Indoor Type Design). Please read the below notes carefully before installation. A Make sure the open voltage and operation voltage is in the range of 10.5-28V, and we recommend the 18V rated voltage solar panel or 24V battery. B Make sure the inverter’s AC voltage and frequency is the same with power grid voltage and frequency. C Installation inverter in the low humidity and well-ventilated place to avoid the inverter damp and overheating, And clear the inflammable and explosive materials around. D Recommended to use 4AWG DC input cable that can handle more than 50A current. E DC input cable no more than 8M, because long DC cable will reduce the voltage from solar panel to inverter, then make some loss. F There must be a circuit breaker between solar power generation and power grid(show like the ” switch A” in figure 1). And there will be no load before the circuit breaker. G Before connect all the connections, you must disconnect the utility power. After make sure the all connections are right then connect the utility power. H If you need to disconnect the mains switch when the solar power generation is in operation, you must disconnect the control switch first(show like the “switch A” in figure 1). I Avoid children touch or play the inverters, in order to prevent electric shock. J Non-professional do not disassemble the inverter, only qualified serviceman can repair it. Connection DC terminal Connect the solar panels positive terminal to inverter’s positive terminal, and negative to negative. And you must screw up the nut to avoid the bad contact. Show as below picture. Connection of AC terminal Before connect the inverter’s AC cable to the socket, you must disconnect the utility power. Then put the AC cable which has holes terminal into the inverter’s 3 feet port and the pin terminal to the socket. Please make sure both of the terminal are connect fastness to avoid bad contact. Show like below picture. Operation After all connection, first open the mains switch, then open the inverter. When the inverter’s green LED shows, it means the inverter start to work. Several or many inverters used in parallel. In order to achieve higher power, we can use this inverter in stack. For example: 4 pcs of 300W grid tie inverter used in stack can achieve 1200W. And the stacking number is unlimited. Single-phase connection Connection electrical diagram of the solar inverter used in single-phase power generation system, show as below. Three-phase connection Connection electrical diagram of the micro inverter used in three-phase generation system, show below. Red LED shows: A? Check if the input voltage to inverter is lower than 10.5V or higher than 28V. Check it the AC cable connect to utility power correct or the utility power is disconnect. No LED shows: A? Check if the DC input voltage is in too low. Check if the DC fuse is broken. Low-voltage protection (input DC voltage is less than 10.5VDC). Over-voltage protection (Input DC voltage is greater than 28.5VDC). Over-temperature protection when the chassis temperature is above 75? The temperature dropped about 2-10 minutes to restart automatically after cooling. Fault Protection (when 110VAC or 220VAC power outage or shutdown). Islanding protection: When the electric supply stop, the inverter automatically shut down output. Green LED flashing: The inverter is adjusting power output. MPPT is in working condition. Green LED long in time: The inverter is in working condition with the maximum output power. How to install the grid tie inverter. Step 1: connect the solar panel to the inverter. Red terminal of inverter is positive, Black terminal is Negative. Step 2: Plug inverter power cable into any outlet at home. Step 3: Switch on the inverter.
