Introduction of Sunshine Grid Tie Inverter. Sunshine Grid Tie Power Inverter is the worlds most technologically advanced inverter for use in utility-interactive applications. This manual details the safe installation and operation of the Sunshine Grid Tie Inverter. This integrated system maximizes energy harvest, increases system reliability, and implifies design, installation and management. The small type solar grid tie power inverter can obtain the solar energy from solar panel, and can tie to the grid through its output cables with no extra equipment. The installation is very convenient and reliable. We call the system combining with small solar grid tie inverter and solar panels as SGPV. The system includes solar panels and small type grid tie inverter and installation kit. Solar panels can be mono silicon, polygon silicon, non-crystal film or any other material that can transform. S olar energy to electric energy. The power of grid tie inverter should be matched to the power of solar panels connected. So the power of SGPV is defined by its solar panels, it can be standardization according to the actual using. The inverter can be connected to any outlets of utility grid at house. The small grid tie inverter monitors the volume, frequency and phase of the home utility grid, then produce pure sine wave AC power that the frequency and phase are as same as the grid’s, and the volume is a bit higher than the grid’s, then according to the current controlled PWM, to control the output power to the grid. The small grid tie inverter just puts out power when the home grid is on. When the sun shines, the PV panel will produces DC voltage, and the grid tie inverter will change the DC voltage to AC voltage and puts out power to the home grid. When the total power of electric apparatus that are using in the house is larger than the output power of the inverters, these power from the inverters will be consumed in the house, this will slow down the power meter, otherwise, the difference of the output power of the inverter between the total used power of the apparatus will go out from the house to the out grid. Input DC Voltage Range. Peak power tracking voltage. AC Output Voltage Range. Dimensions (W x H x D). Note: there are 22v-60v and 45v-90v input voltage optional. Advantage of The Sunshine Grid Tie Power System. More than 1 unit inverters stackable. There are many advantages of SGPV compare with the traditional grid tie power system. Low cost and easy installation – SGPV can make full use of all types of buildings surface that face to the sun in the city as well as fast and easy installation of solar modules and grid tie inverter. It just needs very low maintenance costs. Free combination – SGPV can be used as a separate grid tie system and can be setup as a large solar array with many of them. The quantity of SGPV in the array is just according to your desire. If you are planning to install a grid-tie PV system, in a general way, the solar array and inverter need to be carefully matched to ensure that the inverters voltage and power limits are not exceeded. When you want to increase more solar panels, and if the total power of the solar panels exceeds the allocation grid inverter, it is necessary to increase the cost of a grid inverter. Combination of SGPV does not interact – The traditional solar grid tie system, they offer units ranging in high power output and these units are modular so you can have multiple units operating in parallel for large solar arrays. Although, the traditional grid inverter has MPPT feature (Maximum Power Point Tracking), but the maximum power point is according to the entire series in terms of solar panels array, if the performance of a piece of solar panels in the system, for some reason, such as leaves, bird droppings, dust, shadow, etc. And degrades, the performance of the entire solar power system will decrease. SGPV has no such disadvantage. If the performance of a piece of solar panels in the system degrades, this just effects this piece itself, will not affect other SGPV in the system. Improving the efficiency of the entire solar power system In traditional grid tie system, the solar panels are connected in series, so the MPPT of the inverter is according to the total panels in series, not to every panel, but there is difference between every panel, so not every panel is working at the maximum power, this will reduce the total power of these panel in series. But SGPV has no such disadvantage. Because every inverter of SGPV has MPPT function, so every panel is working at the maximum power, this will increase the efficiency of the entire system. Low power consumption Most of the parts in the small grid-tie inverter are digital ICs and. Low power MCU, so the power consumption of it is low, though the quantity of grid tie inverters. Is increased, but this will not increase the power consumption much of the entire system. Battery Discharge Power Mode. New upgraded firmware enable battery or solar limiter current and power model. User can set the maximum output power of inverter , this can make the inverter work at cooler contition as user want and extend the lifespan of the inverter. User can set kick in/off voltage of the inverter which can flexible using with battery bank depend on users mind and can prevent battery bank from over discharged. The Inverter display can show many information, The main interface of the display and the icons explainations are show above. The inverter also integrate with internal limiter and external limiter function which can prevent excess power from going to the public grid. Select the internal limiter mode, inverter will work under limiter mode, output power of the inverter will be determined by load power. Select the external limiter mode, inverter need a external limiter module working with it. For more details about the limiter function, pls contact supplier. This function only useful with limiter type inverter. Notes: Save the setting after you reconfigurate the working mode or backlight setting. Notes: Battery Discharge Current Mode And Battery Discharge Power Mode are not developed yet. This interface will show the real time grid waveform. The grid voltage and frequency also will show in this interface. The energy interface will show the power generation curve everyday. Today KWH and Total KWH are also show in this page. In this interface, the display shows real time power, PV input voltage, inside temperature, date and time. Clock And Date Setting. Set the clock and date in this page, save the setting before exit. AC Output Current Waveform and PF Test Of 2000W Model. Tested 2000W model at nearly full load, Output current waveform shows good pure sine wave in oscilloscope, PF value also shows in good result, 99.8% PF value. Please note : this inverter is not limiter inverter. If you do not want to sell electric power , you will need a limiter type inverter. Why to choose GAIA grid tie Inverters?
