Perfect electrical protection function. 1000W Grid tie inverter, Pure Sine Wave Inverter. DC10.8V-30V to AC90-140V Output. 18V Solar Panel, Vmp: 18-21V, Voc: 20-24V. This unit was ideally designed for a 18V solar panel. Solar Panel Power: minimum 200W, maximum 1100W. Creative MPPT tech makes efficiency higher than 99%. Consider the conversion rate of solar panel is about 80%, for example, if you need 500W power output from the inverter, you need to connect it to a solar panel that 500 / 0.8 / 0.8 equals about 780W, (780w 0.8 0.8 = 500w). Please be noted, This grid tie inverter cannot be used as off grid/stand alone solar system. The output need to be connected to the grid power. Can not supply power directly to the AC loads. DO NOT use solar controller load ports to connect to the inverter. Mechanical meter:Excess electricity will be uploaded to the grid, reducing electricity bills. For smart meters, it will increase the electricity bill. So you need to choose the version with limiter. Intelligence Fans -on temperature >122 F degree. High-speed ventilation fans to help keep the inverter running at a low temperature. Grid tie inverter is a device which directly converts direct current into alternating current which sine wave, frequency and phase are same as power grid and then feed into utility grid. It is a key device of power generation systems such as PV power generation system. 1000W Grid Tie inverter is a compact unit, which directly converts direct current into alternating current for powering appliances and/or office equipments and connecting to utility grid. The AC output from Smart Micro inverter is synchronized and in-phase with the utility grid. Easy to install, DC connect your solar panel (red terminals connect “+”, black terminals connect “-“). Note 1: Do not connect the positive and negative poles. The LED will not light up. Note 2: Please tighten the DC end of the inverter. Avoid loosening and short circuits. The AC cord to the inverter 3 foot outlet, then the AC cord to home 3 pin AC outlet. The switch of the home outlet must be turned on. Note 1: The local power grid must be normal. In case of power failure, the inverter will automatically stop working (island protection). Note 2: The household outlet switch must be turned on. Otherwise, the inverter cannot be synchronized to the grid. The purpose is let small power inverter become high-power inverter. In order to achieve higher power use requirements, the use of this product can be stacked, such as: 4 grid tie inverter 1000W of stack used is equal to 4000W, and the number of open stacks (No Quantitative Restrictions).
