YSmart Smart Microinverter Introduction

IP Series Grid Tie inverter
3
Grid tie inverter is a device which directly converts direct current into sine wave,
frequency and phase are same as power grid alternating current and feed into power grid. It
is a key device of power generation system such as PV power generation system, small
power wind power generation system. YSmart Smart Microinverter optimized design for
modularization modular power generation systems. They can use with DC power source
such as the mainstream solar module such as 18V, 24V and 36V monocrystal and/or
Polycrystalline solar panels, small power wind generator as well as battery for converting
into alternating current which suitable for feeding into utility grid. Product is stable and
reliable as well as high conversion efficiency. It is best choice for PV power generation
systems and small power wind power generation systems.
YSmart Smart Microinverter can be easy placed and attached to the rack of solar panels. No
need space for independent installation and low voltage DC wire of side of solar panel
connecting to Smart Microinverter can eliminate the risk of high DC voltage which cause
of high power centralized inverter’s series string and/or parallel connections. Distributed
modularization design philosophy for YSmart Smart Microinverter will ensure the
productiveness of the whole system will not affect by a single point of failure. Each Smart
Microinverter is individually connected to one PV module in your array. This unique
configuration means that an individual Maximum Peak Power Point Tracker (MPPT)
controls each PV module. This ensures 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. That is, although individual PV modules in the array may be affected by
shading, soiling, orientation, or PV module mismatch, the Smart Microinverter ensures top
performance for its associated PV module. The result is maximum energy production from
your PV system and gets return on investment in less time.
Advantages of YSmart Smart Microinverter
1. Unique circuit design, choice of import industrial electronic components, higher
efficiency, more stable performance.
2. Creative MPPT technology, efficiency more than 99%, faster reaction, more sensitive of
reaction and more reliable of Maximum power point locking.
3. Parallel modular design, small volume, distributed installation, easy for system
configuration, flexible for combination, strong expansibility of system.

maintenance of the YSmart Smart Microinverter. To reduce the risk of electrical
shock, and to ensure the safe installation and operation of the YSmart Smart
Microinverter, the following safety symbols appear throughout this document to
indicate dangerous conditions and important safety instructions.
Follow instruction closely.
Safety Instruction
Do not use Smart microinverter in a manner not specified by the manufacturer. Doing so
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.

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 YSmart 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.
Do NOT disconnect the PV module from the Smart Microinverter without first removing AC
power.
The better disconnect DC terminal first. It may cause of components damaged if removing
AC power first when Smart Microinverter still operation. It is available to disconnect AC
power first when Smart Microinverter is not working but the better to disconnect the DC
terminal first.
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
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 Micro
inverter’s not,
e.Check if the utility grid voltage and frequency are fit in with the serviceable
range of Smart Microinverte 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,
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
Microinverte 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 source 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.
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
source 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.
