3.5 Mounting Steps 1.Use the wall bracket as a template to mark the position of 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. 3. -
Page 12: Electrical Connection
4 Electrical Connection 4.1Grid Connection 4-30KW series inverters are designed for three-phase grid. Voltage is 400V, 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. - Page 13 Table 3: Cable recommended Model Copper Cable Conductor cross-section 4mm² 4K-12K 6mm² 13K-17K Five-core cable（L/N/PE） 10mm² 20K-22K 16mm² 25K-30K Connection Steps 1. Choose the appropriate wire(Cable size:please refer to Table3). 2. Remove 12mm of insulation from the end of wire. 3.

Page 14: Pv Connection
13W-30KW： 4.2 PV connection ◆ Conditions for DC Connection The inverter has 2 independent input : PV1 & PV2 Notice that the connectors are in paired (male and female connectors). The connectors for PV arrays and inverters are H4 connectors; The solar modules connected to the inverter must conform to the Class A requirements of the IEC 61730 standard. - Page 15 ◆ Connecting the PV Array 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.

4.3 RS 485 Cable Connection（Optional） ◆ 485 is provided the function of remote control that allows external control device to make the inverters remote cluster control through 485 port on the inverter. ◆ When routing the signal cable, ensure that it is separate from the power cable and away from interfering sources to prevent communication from being affected. -
Page 17: Turn-Off The Inverter
4.4 Turn-off the Inverter Do not disconnect the DC connectors under load. Turn-off the inverter step: 1.Disconnect 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. -
