1. GDV Grid Series 1 Installation Connection 1 Red terminal Connect DC positive black terminal Connect DC negative Show in Figure 1 Will inverter input positive terminal and negative terminal respectively gear into PV panels the output positive wire and negative electrode Figure 1 3 AC socket Connect to the mains Put the side of the AC cord which has holes into the inverter with 3 foot outlet and the other side of the AC cord to home 3PIN AC outlet Show in Figure 2 The AC ponor cord connected RG comer cord plug connec tad to the inverter AC output oa to the power grid interface Figure 2 3 Switch Connect the connections in right way then turn on the switch The inverter starts to work GDV Grid Series Figure 3 2 Grid tied inverter used in the wind and solar street lights Use this product do not need to add solar panel controller battery Connection Method 1 Figure 4 below ation capacity meter pains e mains solar energyt _ solar energy street lamp controler Figure 4 Connection Method 1 Wind energy solar energy can supply to the grid at the same time then achieve the highest efficiency First consider this connection method Figure 4 3 Stack using In order to achieve higher power use requirements this product can be stacked such as 5 grid inverter300W stacking can achieve 1500W And the number of the stacking is unlimited Used as shown in Figure 5 Minia2. Multiple small power inverters in parallel can achieve large output power High Frequency High Conversion Rate Adapt high frequency converter the output more efficient 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 MPPT is for short of Maximum Power Point Tracking It means the controller can sense the voltage of the solar panels on time and can track the highest voltage and current VI Then made the inverter discharge to power grid with the highest efficiency The peak voltage Vpp of the solar panels is about 19 5V when it in factory And the environment temperature is 25 C The reason of setting this temperature interestingly different from the subjective imagination we ordinary people the conclusion may let us surprised is that when the weather is very hot solar panels peak voltage will fall to about 17 5 V while in cold weather the peak voltage can achieve 20 8 V Now we back to contrast the difference of MPPT solar energy grid inverter and traditional inverter The traditional solar inverter is a bit like the manual gearbox When the engine speed increase while the gearbox
3. 60Hz frequency of AC Frequency range 45Hz 63Hz directly connected to the solar panels do not need to connect the battery Using precise Dynamic differential pressure type 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 1 Differential pressure type MPPT 0 1 V accuracy 2 Power lock 5W AC output 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 1 AC phase shift lt 1 2 Over zero protection 0 2 VAC 3 AC switching 50Hz 60Hz automatic detection automatic switching Synchronous High frequency Modulation In the process of the grid usually adapt the same phase angle in parallel Ge 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 1 Modulation synthesis half wave and full bridge modulation synthesis 100Hz 120Hz 2 Synthetic way MOSFET full bridge 3 High frequency 50KHz Pure
4. Sine Wave Output Use SPWM directly to make pure sine wave output 1 Output waveform Adopt complementary PWM to push pull pure sine wave 2 Generate means enhancement mode SPWM 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 Used more convenient 1 Luminosity sampling point power sampling point 2 High precision AD sampling integral AD sampling method Power Automatically Locked APL In different current fluctuations we should use the MPPT function When the MPPT function adjusted to the GDV Grid Series maximum power point the product automatically powers locked in maximum power point then made the output power more stable 1 Power lock The biggest sampling point of MPPT 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 Current Limit Protection Current limit Stack Multiple Machines
5. install inverter in the low humidity and well ventilated place to avoid the inverter over heating and GN clear around the inflammable and explosive materials When using this product avoid children touching playing to avoid electric shock Recommended Maximum DC input 4AWG cable capable of handling more than 50A of the cable size Optimal length of the DC input line 1 8M or less long cable will allow solar panels to the inverter DC voltage drop caused by wear and tear Connected to a power outlet to provide AC Connected solar panels battery or wind generators DC input DC power supply cable Proposed wind power plant with its own charge controller and load dump
