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, 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
productivenss 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.

Important Safety Information
Read this First
This manual contains important instructions for use during installation and
maintenance of the Smart Microinverter. To reduce the risk of electrical shock, and to
ensure the safe installation and operation of the Smart Microinverter, the following
safety symbols appear throughout this document to indicate dangerous conditions
and important safety instructions
!DANGER! This indicates a hazardous situation, which if not avoided, will
result in death or serious injury.
WARNING! This indicates a situation where failure to follow instructions
may be a safety hazard or cause equipment malfunction. Use extreme
caution and follow instructions carefully.
NOTE: This indicates information particularly important for optimal system
operation
Follow instruction closely.
Safety Instruction
e 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
allinstallation 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 65-70°C. To reduce risk of
burns, use caution when working with microinverters.
● Do NOT disconnect the PV module from the smart Microinverter without first
removing AC power when microinverter still working. The better disconnect AC
terminal first and then disconnect DC terminal so as it help prevent components
damaged and protect the security of the human body.
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
