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.

well as anti-corrosion.

7. Getting electronic circuit design, appearance design and other core
technology patents.

8. Full output voltage 90-260VAC which includes all countries’ voltage
standard. MCU automatic detection and conversion insures that Smart
Microinverter can work with different AC voltages.

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.

Follow instruction closely.

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.

 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.
