1. Introduction

This inverter can be used in parallel with two different operation modes.

1. Parallel operation in single phase with up to 6 units. The supported maximum output power is

24KW/30KVA.

2. Maximum six units work together to support three-phase equipment. Four units support one phase

maximum. The supported maximum output power is 24KW/30KVA and one phase can be up to

16KW/20KVA.

NOTE: If this unit is bundled with share current cable and parallel cable, this inverter is default supported

parallel operation. You may skip section 3. If not, please purchase parallel kit and install this unit by following

instruction from professional technical personnel in local dealer.

2. Package Contents

In parallel kit, you will find the following items in the package:

Parallel board Parallel communication cable Current sharing cable

3. Parallel board installation

This installation steps are only applied to 4K/5K models.

Step 1: Remove wire cover by unscrewing all screws.

Step 2: Remove communication board by unscrewing two screws as below chart.

Step 3: Remove two screws as below chart and remove 2-pin and 14-pin cables. Take out the board under the communication board. Step 4: Remove two screws as below chart to take out cover of parallel communication. Step 5: Install new parallel board with 2 screws tightly. Step 6: Re-connect 2-pin and 14-pin to original position.

Step 7: Put communication board back to the unit. Step 8: Put wire cover back to the unit. Now the inverter is providing parallel operation function. 4. Mounting the Unit When installing multiple units, please follow below chart. NOTE: For proper air circulation to dissipate heat, allow a clearance of approx. 20 cm to the side and approx. 50 cm above and below the unit. Be sure to install each unit in the same level. 5.

Recommended AC input and output cable size for each inverter: Model AWG no. Torque 4KVA 10 AWG 1.4~1.6Nm 5KVA 8 AWG 1.4~1.6Nm You need to connect the cables of each inverter together. Take the battery cables for example: You need to use a connector or bus-bar as a joint to connect the battery cables together, and then connect to the battery terminal. The cable size used from joint to battery should be X times cable size in the tables above.

7. LCD Setting and Display Setting Program: Program Description Selectable option Single: When the units are used in parallel with single phase, please select “PAL” in program 28. It is required to have at least 3 inverters or maximum 6 inverters to support three-phase equipment. It’s required to have at least one inverter in each phase or it’s up to four inverters in one phase. Please refers to 5-2 for detailed information.

Step 4: Switch on all AC breakers of Line wires in AC input. It’s better to have all inverters connect to utility at the same time. If not, it will display fault 82 in following-order inverters. However, these inverters will automatically restart. If detecting AC connection, they will work normally. LCD display in Master unit LCD display in Slave unit Step 5: If there is no more fault alarm, the parallel system is completely installed. Step 6: Please switch on all breakers of Line wires in load side.
