PIP-HS/MS Series Parallel Installation Guide
1. Introduction
This inverter can be used in parallel
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
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.

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.
- Page 2 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. -
Page 4: Recommended Battery Capacity
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. - Page 5 5-1.
