User Manual 1.Solid brick/concrete, or strength equivalent mounting surface; 2.Inverter must be supported or strengthened if the wall’s strength isn’t enough(such as wooden wall, the wall covered by thick layer of decoration). Please avoide direct sunlight, rain exposure, snow laying up during. ◆...
User Manual 3.4 Space Requirement 3.5 Mounting Steps 1.Use the wall bracket as a template to mark the position of the 3 holes on the wall. 2.Drill holes with driller, make sure the holes are deep enough (at least 60mm) for installation, and then tighten the expansion tubes.
User Manual 4 Electrical Connection 4.1Grid Connection SI-6K-S2 Series inverter are designed for single phase grid. Voltage is 220/230/240V, frequency is 50/60Hz. Other technical requests should comply with the requirement of the local public grid.Micro-breaker should be installed between inverter and grid, any load should not be connected with inverter directly.

User Manual Connection Steps 1. Choose the appropriate wire(Cable size: refer to Table3). 2.Remove 10mm of insulation from the end of wire. 3.Thread cables through pressure screw, seal ring, threaded sleeve in sequence. 4. insert the stripped and bared conductors L,N,PE into the screw terminals with sign L , N ,PE on the socket element and tighten the screws firmly.
User Manual 4.2 Earth Connection Users must addtionally earth the inverter to the enclosure of a second earthing or equipotential bonding. This prevents electric shock if the original protective conductor fails. Earth Connection Steps: 1. Strip the earthing cable insulation and insert the stripped cable into the ring terminal, then clamp it .
User Manual Danger to life due to lethal voltages! ◆ PV array supplies d.c voltage to inverter when exposed to light,before connecting the PV array, cover some light screens above PV arrays,ensure that the DC switch and AC breaker are disconnect from the inverter.
User Manual 4.4 Turn-off the Inverter Do not disconnect the DC connectors under load. Turn-off the inverter step: 1.Disconect the line circuit breaker from single-phases grid and prevent it from being reactivated. 2.Turn off the dc switch. 3.Check the inverter operating status. 4.Waiting until LED, OLED have go out, the inverter is shut down.
User Manual 6 LCD Operation The main interface is the default interface, the inverter will automatically jump to this interface when the system started up successfully or not operated for a period of time. Menu interface - 15 -...
User Manual 7 Maintenance and Cleaning 7.1 Maintain Periodically 1.Checking Heat Dissipation If the inverter regularly reduces its output power due to high temperature, please improve the heat dissipation condition. Maybe you need to clean the heat sink. 2. Cleaning the Inverter If the inverter is dirty, turn-off the AC breaker and DC switch ,waiting the inverter shut down ,then clean the enclosure lid, the display, and the LEDs using only a wet cloth.
