1. Introduction

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

1. Parallel operation in single phase with up to 4 units. The supported maximum output

power is 16KW/20KVA.

2. Three units work together to support three-phase equipment, one inverter per phase.

The supported maximum output power is 12KW/15KVA.

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.

PIP-HS/MS Series 4KVA/5KVA Parallel Installation

*Note: at the moment only 4048HS or 4048MS (both 5kva models) are offered this feature.

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. 500mm 500mm 500mm 500mm 500mm 500mm 500mm NOTE: For proper air circulation to dissipate heat, allow a clearance of approx. 50 cm to the side and approx. 50 cm above and below the unit. Be sure to install each unit in the same level. 5.

6. AC Input Connection Parallel in single phase Connect Line wires of AC input from each unit to Line BUS bar. Connect Neutral wires of AC input from each unit to Neutral BUS bar. Refer to below figure for connection of AC input. Breaker Breaker Support three-phase equipment Connect Line wires of the inverter to each phase of the utility. Connect Neutral wires of AC input from each unit to Neutral BUS bar. Refer to below figure for connection of AC input.

WARNING: Only Line wires can be connected breaker. It’s not allowed to add breaker into Neutral wires between inverter and the BUS bar. All Neutral wires are connected to the BUS bar directly, and you can add a breaker between the utility and the bus bar in the distributor. WARNING: Be sure the length of all AC input cables is the same to guarantee reliability of sharing current in each unit. WARNING: Recommended spec of cable from inverter to BUS bar and breaker is listed as below.

10. LCD Setting and Display Setting Program: This setting is only available when the inverter is in standby mode (Switch off). Program Description Selectable option Single: When the units are used in parallel with single phase, please select “PAL” in program 28. Parallel: Operation to support three-phase equipment is required to have three inverters. L1 phase: This setting for each unit should be different in L1 phase, L2 28 AC output mode phase and L3 phase separately.
