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.

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 withMicroinverters.
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.

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,
b) Check if the DC connections to Smart Microinverter are correct or
not,
c) Check if any reverse DC connections for positive or negative or not,
d) Check if DC input voltage is within the range of the Smart
Microinverter’s or not,
e) Check if the utility grid voltage and frequency are fit in with the
serviceable range of Smart Microinverter or not,
f) Check if fuses of DC side are fusing or not,
g) Check if utility grid voltage properly connecting to Smart
Microinverters or not.
2.DC power supply is normal but no power output:
a) Check if utility grid voltage is connecting to Smart Microinverter or
not,
b) Check if utility grid voltage is fit in with the serviceable range of
Smart Microinverter or not,
c) 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,
d) 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
