Safety 2 Safety 2.1 Appropriate Usage The SolarLake Series is a PV inverter which converts the DC current of a PV generator into AC current and feeds it into the public grid. PV Modules Grid-connected Inverter Grid Figure 2 PV Grid-connected System 2.2 Important Safety Instruction Danger!...
Safety 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.

Introduction ●Terminals of PV inverter RS232 COM1 COM2 RS-232 AC GRID AC Output DC Switch DC Input Figure 4 Terminals of PV inverter for 10 KW~17 KW(DC switch is optional) Note: For safety reasons, the use of a DC switch is recommended. Between the PV modules and the power modules may be mandatory in some countries.
Introduction &Technical Data Note: The AC output terminal is most length part at the bottom of inverter, so take care of the AC output terminals, do not make it stand on the ground or other materials while moving or lifting the inverters, otherwise will make terminal damaged. 4 Technical Data 4.1 Input (DC) SolarLake...
Installation 5.2 Installation precaution 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!...
Installation 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.
Installation Step 3 Step 4 Figure 8 Bracket installation Use the bracket to install the inverter onto the narrow vertical panel (or wall). make Step2: upper corner part of inverter hanging onto the bracket, lower part match the standard of the bracket.See step 2.

Installation Input Output 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.
Installation&Operation Start inverter a. Turn on DC switch and AC grid. b. Inverter will start up automatically when PV panels generate enough energy. when operating normally, the LED and LCD will indicate normal information which means inverter starting up successfully. If it is the first time start the inverter Please refer to chapter 6.1 .1 LCD commission -ing setup operation steps, if it is not the first time start, find the inverter is malfunction, please refer to chapter 8.1 troubleshooting table.
