Page 11: System Diagram And Connection Label
The SUNLEAF series only operates when it is connected to the AC grid and can not operate as a stand-alone unit. The simplified connection diagram of the inverter is as follows. -
Page 12: Connecting To The Ac Grid (Utility)
integrated DC switch in Fig.6. D. AC Grid (Utility): Referred to as “grid” in this manual, is the way your electric power company provides power to your place. Please note that Inverter can only connect to low-voltage systems (namely, 230/240Vac, 50Hz). Note: provides an integrated switch box that includes DC switch, AC switch, DC fuse, AC fuse, DC SPD and AC SPD devices as an option. -
Page 13: Connecting To Pv Panel (Dc Input)
A. Under any condition! Make sure the maximum open circuit voltage (Voc) of each PV string is less than 500VDC for SUNLEAF 3000TL, SUNLEAF 4000TL and SUNLEAF 5000TL. The length of input wire must be less than 30m. By the way, generally, in the lowest ambient temperature of your installing field, the Voc of PV string is the highest. -
Page 14: Ac Output Protective Device
B. For model SUNLEAF 4000TL the AC output side should be in series an over current protective device which rated 25A, max rated breaking capacity 6KA. C. For model SUNLEAF 3000TL the AC output side should be in series an over current protective device which rated 20A, max rated breaking capacity 6KA. -

Page 18: Inverter Start-Up And Operation
The current time 4. INVERTER START-UP AND OPERATION WARNING: Do not place any items on SUNLEAF inverter during operation. When the inverter is operating, do not touch the heat sink since some parts may become very hot. Step 1: Ensure that the AC cable and DC cable is connected correctly, unused DC plugs and AC terminal cover are sealed. - Page 19 Standby: The PV string can only provide just enough voltage to minimum requirements of the internal controller unit. Waiting: When the PV string DC voltage is greater than 100V, the inverter enters a “waiting” state and attempts to connect to the grid. Normal: When PV string DC voltage is greater than 150V, Inverter operates in the normal state.

5. COMMUNICATIONS 5.1 Data communication with RS232 Fig. 10 RS232 serial port and special RS232 cable Open the cover of RS232 serial port, connect solar Inverter and computer by special RS232 cable. By the way, the communication distance should be below 10m. -
Page 21: Rs485 Daisy Chain
Straight-Through. 5.2.3 RS485 Daisy Chain RJ45 connectors may be used to connect a single SUNLEAF inverter or multiple SUNLEAF inverters daisy chained together. Up to 31 inverters can be daisy chained. Recommended maximum daisy chain length is 1000m. -
Page 22: Monitor Inverter
Fig.12 Multiple daisy-chain connection NOTE: The RS485 link supports up to 31 inverters. NOTE: The RJ45 socket with120Ω terminal resistor should be installed at the last inverter in the chain. Even if there is only one inverter, the 120Ω terminal resistor is also necessary. -
