Feature: 1. MAIN FUNCTIONS: This miniature grid connected inverter is a compact unit that converts direct current to alternating current directly to power appliances or office equipment and connect to the utility grid. The AC output of the micro inverter is synchronized and in phase with the utility grid 2. WORKING PRINCIPLE: The solar micro inverter is a device that converts the direct current of the solar panel into alternating current. Possess small size, small capacity, often used in small solar systems. Maximum power point tracking can be achieved to maximize the overall output power. Built in high accuracy instrument, you can see the working status of each component 3. HIGH CONVERSION RATE: Grid connected inverter conversion efficiency is high, the highest conversion efficiency can reach 93%, improve the use efficiency 4. SIMPLE OPERATION: The grid connected inverter needs to be connected to the power grid, which is convenient for you to use 5. EXCELLENT ALUMINUM ALLOY MATERIAL: The micro inverter is made of aluminum alloy material, which is durable and can be used for a long time Specification: Item Type: Solar Micro Inverter Model T-120 T-150 T-180 Operating voltage range 10.8-30V MPPT Operating voltage range 12-30V Starting voltage 10.8V Maximum input power 120W 150W 180W Maximum input current 7.5A 9.3A 11A Maximum allowed photovoltaic panel power 120W 150W 180W Recommended add PV panel parameters 18V at 120W 18V at 150W 18V at 180W Output parameter 120V/230VAC self adaptation Output peak power 120W 150W 180W Rated output power 110W 140W 170W Output voltage range 80-160VAC/180-280VAC Output current range 0.8A/0.4A 1.08A/0.56A 1.25A/0.65A Output frequency range at 50Hz:47-53Hz;at 60Hz:57-63Hz Connected circuits per string number 6 units(single at 120VAC); 12 units(single phase at 230VAC) Output efficiency MPPT tracking efficiency 0.99 Maximum output efficiency 93% Total harmonic distortion rate ＜5% Night loss ＜0.5W Appearance and technical characteristics Operating temperature range -20℃-65℃ Storage temperature range -40℃-75℃ Waterproof class IP65 Heat dissipation mode Self cooling Power transmission mode Reverse transmission, load takes precedence Electromagnetic compatibility EN50081.part1 EN50082.Part1.CSA STD.C22.2 No.107.1 Grid disturbance EN61000-3-2 safety standard EN62109.ULSTD.1741 Power grid detection DIN VDE 0126IEEE STD.1547.1547.1 and 1547.A . Package List: 1 x Inverter1 x AC Power Cable1 x User Manual2 x Mounting Screw6 x Gasket2 x Nut Note: 1. Use only solar panels to connect to this device. Do not use with batteries, please use with caution.6. This device is an ON GRID micro inverter. To make it work normally, must be correctly connected to the power grid, and the power grid works normally. When the power grid stops working, will also stop generating power.3. The photovoltaic panel voltage shall not exceed the maximum input voltage of the inverter.4. Do not exceed the maximum input power of the inverter photovoltaic panel power.5. The positive and negative poles of solar panels cannot be reversed. If you extend the solar panel cable. You need to be careful with that.6. Avoid direct sunlight and rain during installation.
