Parallel Installation Guide

1 Introduction

This inverter can be used in parallel with maximum 3 units. The supported maximum

output power is 30KW/30KVA.

When installing multiple units, please follow below chart.

NOTE:

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.

For proper air circulation to dissipate heat, it’s necessary to allow a clearance

working.

Be sure the length of all battery cables is the same. Otherwise, there will

Recommended AC input and output cable size for each inverter:

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. “X” indicates the

number of inverters connected in parallel.

Regarding cable size of AC input and output, please also follow the same principle.

CAUTION!!

overcurrent of battery.

Please install a breaker at the battery side. This will ensure the inverter

Setting Program:

The parallel function setting is only available by SolarPower. Please install SolarPower

in your PC first.

For setting, you can set the inverter one by one through RS232 or USB port.

But we suggest to use SNMP or Modbus card to combine the system as a centralized

monitoring system. Then, you can use “SYNC” function to set all the inverters at the

same time. If using SNMP or Modbus card to set up program, the bundled software is

SolarPower Pro.

Use SNMP card to synchronize the parameters:

Each inverter should be installed one SNMP card. Make sure all of the SNMP cards are

connected to the router as a LAN.

Use Modbus card to synchronize the parameters:

Each inverter should be installed one Modbus card. Make sure all of the Modbus

cards are connected to each other and one of the Modbus cards is connected to the

computer by RS-485/RS232 converter.

Launch SolarPowerPro in computer and select Device Control >> Parameter Setting

>> Parallel output. Two options: Enable or Disable.

If you want to use parallel function, please choose “Enable” and press “ ”

button. Then, “ ” button will be shown is the screen. Please be sure to click

“ ” button before clicking “ ” button.

There is a “Sync” button in each parameter setting. When “Sync” is clicked and

“Apply” is pressed, this new setting will be applied to all inverters. If not, this setting

is only effected in current inverter you choose.

Note: Without centralized monitoring system, “Sync” function is not effective. Then,

you have to set up the inverter one by one through serial communication port.

Fault code display:

Step 1: Check the following requirements before commissioning:

 Correct wire connection.

 Ensure all breakers in Line wires of load side are open and each Neutral wire of

each unit is connected together.

Step 2: Turn on each unit and set “enable parallel for output” on SolarPower or

SolarPower Pro. And then, shut down all units.

Step 3: Turn on each unit.

NOTE: Master and slave units are randomly defined. Warning 02 is AC GRID voltage

low.

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.

1.Restart the inverter.

2.Check if L1/L2/L3/N cables are not

connected with wrong sequence in all

inverters.

3.Make sure the sharing cables are connected

in all inverters.

4.If the problem remains, please contact your

installer.

1.Check if sharing cables are connected well

and restart the inverter.

2.If the problem remains, please contact your

installer.

1.Check if communication cables are

connected well and restart the inverter.

2.If the problem remains, please contact your

installer.

1.Disconnect all of power source.

2.Only connect AC input, and press Enter key

to let it working in bypass mode.

3.Check if the problem happens again or not,

and feed back the result to your installer.
