Smart Microinverter Introduction
Smart 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 Microinverter is synchronized and in-phase with the utility grid. It is a key device of power generation systems such as PV power generation system, wind turbine power generation system. Smart Microinverter specially optimized design to work with modularization of DC power supplies which includes the mainstream solar modules, 18V (36 cells), 24V (60 cells) and 36V (72 cells) monocrystal and/or Polycrystalline solar panels, wind turbines and batteries. Smart Microinverters are stabilization, reliable and high conversion efficiency items. It is the best choice for PV power generation systems.

Smart Microinverter can be easily placed and attached to the rack underneath of PV module. No need spaces for independent installation and low voltage DC wire connects from the PV module to Smart Microinverter can eliminate the risk of high DC voltage. Distributed modularization design philosophy for Smart Microinverter insures the productiveness of the whole system and will not affect by a single point of failure. Each Smart Microinverter is individually connected to each PV module in the array. This unique configuration means that an individual Maximum Peak Power Point Tracker (MPPT) controls each PV modules and insures that the maximum power available from each PV module is exported to the utility grid regardless of the performance of the other PV modules in the array which may be affected by shading, soiling, orientation or mismatch, etc. Smart Microinverter insures top performance for maximizing energy production from the whole PV system and gets return on investment in less time.

Safety Instruction

• Do not use Smart Microinverter in a manner not specified by the manufacturer. Doing so may cause death or injury to persons, or damage to equipment.
• Perform all electrical installations in accordance with all applicable local electrical codes.
• Be aware that only qualified personnel should disassemble and repair the Smart Microinverters and non-qualified personnel should not install and/or repair.
• Do not attempt to repair the Smart Microinverter; it contains no user-serviceable parts. If it fails, contact customer service to claim a return merchandise authorization and start the replacement process. Tampering with or opening the Smart Microinverter will void the warranty.
• If the AC cable connector on the Microinverter is damaged or broken, do not install the unit.
• Before installing or using the Smart Microinverter, read all instructions and cautionary markings in the technical description and on the Smart Microinverter System and the PV equipment.
• Connect the Smart Microinverter to the utility grid only after you have completed all installation procedures and after receiving prior approval from the local electrical utility company.
• Be aware that the body of the Smart Microinverter is the heat sink. Under normal operating conditions, the temperature is 15°C above ambient, but under extreme conditions the Microinverter can reach a temperature of 75°C. To reduce risk of burns, use caution when working with Microinverters.
• Our suggestion is that do NOT disconnect the PV module from the Smart Microinverter without first removing AC power when Smart Microinverter still operation because it may cause of components damaged.
• Keep away from children, no touching, no playing so as not to electric shock when using.
• Please installed in place of low humidity and well-ventilated so as to avoid inverter overheating, as well as clear around the inflammable and explosive materials.

Smart Microinverter Stack Wiring Diagram

Microinverter or not,

1. Please visual inspection for the LED operation status, red LED will turn off and green LED will flash or run when inverter connecting with DC power supply  which input voltage is fit in with the range as specified and power grid properly. If still no power output when green LED flash or run, probably internal components are damaged, in such case, please turn the defective inverter back for further analyze.
2. Please visual inspection for the LED operation status, red LED still turn on and green LED without any flash or run when inverter connecting with DC power supply which input voltage is fit in with the range as specified and power grid properly, probably internal components are damaged, in such case, please turn the defective inverter back for further analyze.

Packing Specification

Installation

1. Diagrammatize DC input and AC output terminals,
2. Attach the Smart Microinverter to the racking or fix onto the wall,
3. Properly connect the positive and negative of solar panel and Smart Microinverter,
4. AC power cable connects with Smart Microinverter and residential power grid which refers to low voltage civilian single-phase power grid.
5. Switch on power grid after check for input and output connections are correct and then switch on the Smart Microinverter. The Red/green LED lights up at the same time and then red LED lights off follow on and green LED flash fast, it is means that Smart Microinverter is run for MPPT operation. When green LED long light and it is means that maximum power point lock-in, Smart Micro inverter proper functioning and output steady.

Status Indications of LED

Red LED indicator lights up under any conditions include but not limited:

• Low-voltage protection (DC input voltage lower than Min. input voltage of inverters),
• Over-voltage protection (DC input voltage higher than Max. input voltage of inverters),
• Over-temperature protection (inverters will shut down for power output when temperature of body of inverters higher than 65-75℃, and inverter will be automatically restart up when temperature down to 40-50℃.)
• Power grid fault protection when 110VAC or 220VAC grid power outage and/or tripped.
• Islanding protection: inverter will be automatically shut down for power output when disconnect with power grid.
• Short-circuit protection: inverter stops work when output line short-circuits..
• Red LED lights on for a while and then green LED lights on in one second when inverter starts to work.

Green LED indicator lights up under any conditions include but not limited:

• Green LED flash: adjusting for power output, MPPT operating for tracking.
• Green LED long light: indicates inverter locking-in Max. output power operation status.
• When green LED flash from the bottom up in turns, it is indicates the inverter is locked at maximum power point as well as the output power is steady. The more power output, the faster running of green LED.

Please note that above operations only run at grid-connected status. Troubleshooting a non-operating Smart Microinverter

System halted and /or without power output
