On Grid Tie Inverter 600W 11V-32VDC Input 220V AC Output with MPPT Function 99% Efficiency Pure Sine Wave for Solar Energy Systems
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) 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.

Status Indications of LED
1. Red LED indicator lights up under any conditions include but not limited:
a) Low-voltage protection (DC input voltage lower than Min. input voltage of inverters),
b) 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°C,
and inverter will be automatically restart up when temperature down to 40-50°C.)
b) Power grid fault protection when 110VAC or 220VAC grid power outage and/or tripped.
c) Islanding protection: inverter will be automatically shut down for power output when disconnect with power grid.
d) Short-circuit protection: inverter stops work when output line short-circuits..
e) Red LED lights on for a while and then green LED lights on in one second when inverter starts to work.
2. Green LED indicator lights up under any conditions include but not limited:
a) Green LED flash: adjusting for power output, MPPT operating for tracking.
b) Green LED long light: indicates inverter locking-in Max. output power operation status.
c) 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.
3. Please note that above operations only run at grid-connected status.
Troubleshooting a non-operating Smart Microinverter
1. System halted and /or without power output
a) Check if switch of Smart Microinverter is turn on or not,
