2.2 Important Safety Instruction
Danger！
Danger to life due to high voltages in the inverter!
•All work on the inverter must be carried out by qualified personnel only.
•The appliance is not to be used by children or persons with reduced
physical sensory or mental capabilities, or lack of experience and
knowledge, unless they have been given supervision or instruction.
•Children should besupervised to ensure that they do not play with
the appliance.
Caution！
Danger ofburn injuries due to hot enclosure parts!
During operation, the upper lid of the enclosure and the enclosure body
may become hot.
Caution！
Possible damage to health as a result of the effects of radiation!
•Do not stay closer than 20 cm tothe inverter for any length of time.
Safety

07
Warning！
Ensure input DC voltage ≤ Max. input DC voltage .Over voltage may cause
permanent damage to inverter or other losses, which will not be included
in warranty! This chapter contains important safety and operating
instructions. Read and keep this Operation Guide for future reference.
Note！
Grounding the PV generator. Comply with the local requirements for
grounding the PV modules and the PV generator. Samil Power recommends
connecting the generator frame and other electrically conductive surfaces
in a manner which ensures continuous conduction and ground these in
order to have optimal protection of the system and personnel.
2.3 Explanation of Symbols

CE guidelines.
● Important Safety Instructions
When using the product, please do remember the below information to avoid the fire, lightning or
other personal injury:
Safety

08
Warning！
Authorized service personnel must disconnect both AC and DC power from
the SolarLake Series inverter before attempting any maintenance or cleaning
or working on any circuits connected tothe SolarLake Series inverter.
● Before using the SolarLake Series inverter, read all instructions and cautionary markings on
the SolarLake Series inverter, and all appropriate sections of this guide.
● Use only attachments recommended or sold by Samil Power. Doing otherwise may result in
a risk of fire, electric shock, or injury to persons.
● To avoid a risk of fire and electric shock, make sure that existing wiring is in good condition
and that wire is not undersized. Do not operate the SolarLake Series inverter with damaged or
substandard wiring.
●Do not disassemble the SolarLake Series inverter. It contains no user-serviceable parts. See
Warranty for instructions on obtaining service. Attempting toservice the SolarLake Series
inverter user self may result in a risk of electric shock or fire and will void user warranty.
● To reduce the risk of electric shock, authorized service personnel must disconnect both AC
and DC power from the SolarLake Series inverter before attempting any maintenance or cleaning
or working on any circuits connected to the SolarLake Series inverter. Turning off controls will
not reduce this risk.
● Keep away from flammable, explosive materials to avoid fire disaster.
● The installation place should be away from humid or corrosive substance.
● To avoid electric shock accident, please do not disassemble the inverter because there are
high-voltage capacitances installed inside the inverter. Fatal High-voltage will remain in the inverter
after its disconnection with grid after 5 minutes.
● To reduce the chance of short-circuits, authorized service personnel must use insulated
tools when installing or working with this equipment.

Warning！
Before installation and maintenance,AC and DC side doesn’t carry
electricity, but if DC side is just disconnected, capacitance still contains
electricity, so please wait for at least 5 minutes to ensure the capacitors
completely release the energy and inverter is not electrified.
Note！
Inverters must be installed by qualified person.
SamilPower assures the product guarantee of the SolarLake series inverters during five years
after your purchase, if the installation site does not meet the instructions described in this manual,
it is out of warranty. The warranty is limited tothe costs of repair and/or replacement of the
product by Samil Power only.
Ventilation is very important to cool the inverter, For outdoors application, the inverter requires at
least 50 cm (see table 2) of clearance among the other units and ground. it is recommended
that the same clearance(50cm).

5.3 Preparation
Below tools are needed before installation.
Figure 7 Installation tools
Installation Tools: crimping pliers for binding post and RJ45, screw drivers and manual wrench
and ø 8 driller, rubber hammer.
5.4 Installation Steps
Step1: Drill holes in the wall with ø 8 driller according to the size of bracket. Keep drilling vertical
to the wall, and don’t shake when drilling to avoid damage to the wall. It need repositioning
and drilling holes if the hole with much error. Then put expansion pipe into the hole vertically,
use rubber hammertotap the pipe into the wall completely. After that, 5 screws should be twisted
into pipes with bracket. See step 1.

Step 3 Step 4
Figure 8 Bracket installation
Step2: Use the bracket to install the inverter onto the narrow vertical panel (or wall). make
upper corner part of inverter hanging onto the bracket, lower part match the standard of the
bracket.See step 2.
Step3: Make sure the bracket and the inverter side screw holes in a line and matching
well, put the screw(there are left and right 2 screws ) into the hole and drive into the
inverter tightly. See step 3.
Step4: Lock the inverter and the bracket with lock for safety consideration. (This is
optional for users. User can select the lock according toyour requirements).See step 4.
5.5 Connections of the PV power system
●PV String input connection
SolarLake series inverters (SolarLake 10000TL, SolarLake 12000TL, SolarLake 15000TL
and SolarLake 17000TL) can be connected to2PV string groups, each group can divided
into 2-strings PV modules. Please select PV modules with excellent function and reliable
quality. Open-circuit voltage of module arrays connected in series should be ＜Max. Input
DC (Table 3) input voltage; operating voltageshould be conformed to MPPT voltage range.

Please use PV cable to connect modules to inverter. From junction box(Must have fuse
spec.:1000V, 25A fast action) to inverter, voltage drop is about 1-2%. So we suggest
the inverter install near PV module, in order to save cable and reduce DC loss.
Note！
Please don’t connect the PV panel positive or negative to ground.
And do not apply for thin film panel.
Figure 9 Use multimeter to measure module array voltage and detect the polarity
Note :Check the PV+ and PV- from the PV string combiner box correctly, Make sure the PV+
and PV- are connected correctly.
Warning！
PV module voltage is very high which belongs to dangerous voltage
range, please comply with electric safety rules when connecting.
Warning！
When there is something wrong with module arrays, modules can be
connected with PV grid-tied inverter only after eliminating these problems.

Note:For safety reasons,make sure you select the correct specification cables for installation,
otherwise the power will make the cable hot and overload, it could result in death or serious injury.
Below are the steps for AC output wiring.
Step1: Get out of the four screws at four corners of the cover, get off the cover.
Step2: There are 5 white terminals, which are PE, N, L3(T), L2(S), L1(R). Put the 5 wire of AC cable
through the house tunnel, then put the wire into the terminals correctly(make sure the phase
sequence is correctly connected）.
Step3: After 5 wires are connected with terminals please check the wire is in right location.
(L wire is connected with L terminal)
Step4: Put the terminal house on the terminals, get four screws on.
RCMU breaker should be installed between inverter and grid, and its rated fault current:
100 mA≤Ifn≤300 mA，0.1S，Any load should not be connected with inverter directly.

Figure12 Incorrect Connections between Load and Inverter
Impedance of SolarLake inverter AC connecting dot should be less than 2 Ω. To ensure reliable
anti-islanding function , PV cable should be used to ensure wire loss ＜1% than normal power.
Moreover, length between AC side and grid connecting dot should be less than 150m. Below
chart is cable length, section area and wire loss.

5.6 Run the inverter
Start inverter after checking all below steps
a. Make sure all the DC Switch and AC breaker are disconnect.
b. AC cable is connected to grid correctly.
c. All PV modules are connected to inverter correctly，DC connectors which are not used should be
sealed by cover.
