Page 14: Mounting
5.3 Mounting ➢ Installation Precaution Inverter is designed for outdoor installation (IP 65). Make sure the installation site meets the following conditions: Not in direct sunlight. ● Not in areas where highly Flammable materials are stored. ● Not in potential explosive areas. ●... - Page 15 ➢ Mounting Tools required for installation. Installation tools: crimping pliers for crimping posts and RJ45, screwdriver, manual wrench etc. Step 1: Drill 4 holes in the wall according to the following dimensions, 50~60mm depth. Then use a proper hammer to fit the expansion bolt into the holes. Step 2: Lift up the inverter and align the holes of the inverter with the expansion bolt, mount the inverter on the wall.
- Page 16 Step 4: Use an Allen Wrench to remove the cover screws, and remove the cover. Remove the waterproof cover with a flat-head screwdriver. Wiring box conduit plugs are provided for 1 inch conduit fittings. If used conduit fitting is not 1 inch, an appropriate conduit adapter should be used. Step 5: Insert the conduit and fasten the joint.

Step2. Connect the cables to the BACK-UP: Load1 and Load2 port of the inverter. Requirements for BACK-UP load Battery Connection The Charging & discharging system of this inverter is designed for a 48V lithium battery. Before choosing a battery, please note the maximum voltage of the battery can’t exceed 60V and the battery communication should be compatible with this inverter. - Page 21 ➢ Battery connection diagram ➢ BMS PIN Definition Communication interface between inverter and battery is RS485 or CAN with a RJ45 connector. When using the RS485 protocol, please note that PIN2 must be disconnected！ ➢ Power Connection Battery: Step 1. Use the 2 AWG wire and strip the cable to 15mm. Select two O-terminals with an aperture of M8. Insert the stripped line into the O-terminal and clamp it with a crimping clamp.

Page 45: Fault Diagnosis And Solutions
Fault diagnosis and solutions This inverter is easy to maintain. When you encounter the following problems, please refer to the Solutions below, and contact the local distributor if the problem remains unsolved. The following table lists some of the basic problems that may occur during the actual operation as well as their corresponding basic solutions. - Page 48 10. Inverter Parallel Guide 10.1 Parallel System Diagram Multiple inverters can be installed together to deliver more power. When AC loads are present, all units effectively share the load. The system diagram is as follows.
- Page 49 10.2 Parallel Communication Cable Connection For parallel communication, CAT 5 cables are needed. When using common batteries, BMS cable needs to be connected to the master unit. The inverter shares the BMS information by inter-unit parallel communication cable. 10.3 Parallel Operation Notes 1) Make sure all the units in parallel are with the same software version.
