Product Usage Instructions

Installation

Install the hybrid inverter exactly as you would for grid connection, following the Owner’s Manual for full technical and connection details.

Inverter Connections

• Terminal 5 = Backup port
• Terminal 6 = Generator port
• Terminal 7 = Chassis Earth point

AC House Loads Wiring to Backup Port

Connect house loads wiring to the backup port following AS/NZS3000 guidelines. Ensure proper earthing and cable protection.

Earthing Chassis Requirement

Ensure the chassis is earthed back to the earth bar/MEN in the switchboard using the correct earth cable size as per AS/NZS3000.

Generator AC Connection

Connect the AC output of the generator to the grid AC terminal of the inverter, ensuring proper earthing to the MEN.

PV DC Connection

Connect the PV array within voltage and current ratings using genuine MC4 connectors.

Battery Connection

Connect the battery (up to 6 modules) including Power DC, CAN, and earth connections with correct Evo2 connectors at inverter connection.

COM Cables

Assemble the CAN cable and plug into the control box of the battery. Connect the battery CAN to the CANH and CANL of the COM plug.

Commissioning

Follow the same commissioning sequence as for a Grid-Connected system to enable firmware updates. Power up the system with PV and battery only, update all firmware.

Additional settings for Generator V1.0

Applicability

SH5.0RS, SH6.0RS SH8.0RS, SH10RS

The above Hybrid Inverters can be connected to a backup Generator providing:

• The most recent firmware for dongle Inverter and battery is
• There is enough generator capacity to supply loads and charge the
• Generator is 2-wire auto-start
• The designer is responsible for generator selection and system

Installation

Install exactly as you would for grid connect, except :

• Generator output connected to AC
• Energy meter not
• Additional settings (shown below)

Important! Please refer to the Owner’s Manual for full technical and connection details for basic installation.

**Inverter connections**

Terminal 5 = Backup port Terminal 6 = Generator port

Terminal 7 = Chassis Earth point

__

AC house loads wiring to backup port

The Backup wiring must be done in accordance with AS/NZS3000 etc. Ensure correct Earthing and cable protection etc.

Connect house loads wiring to the backup port, ensure that the earth wire is connected between chassis and earth bar. Do not connect PE at the backup port.

Earthing chassis requirement (From the install manual):

Ensure that the chassis is earthed back to the earth bar/MEN in the switchboard as per the install manual. Use correct earth cable size (AS/NZS3000).

__

Generator AC connection

Connect the AC output of the generator to the grid AC terminal of the inverter (Consult generator manual for details) ensuring the earth is connected to the MEN.

PV DC

Connect the PV array ensuring that the voltage and current ratings are not exceeded. Use the supplied genuine MC4 connectors.

Battery

Connect the battery (Maximum 6 modules in a stack) including the Power DC, CAN, and earth.

Ensure to use the correct Evo2 connectors at inverter connection.

COM cables

Assemble the CAN cable and plug into the control box of the battery, using the supplied tool to securely lock the RJ45 plug.

No energy meter required.

Ensure to properly terminate the Com cables using the supplied blue bootlace ferrules.

__

Connect the battery CAN to the CANH and CANL of the COM plug and Connect the Generator auto-start to the DO using a 2-conductor circular control wire.

(Communication pinout diagrams may vary between models. All inverters have a pinout map on the left-hand side of the inverter.)

Commissioning

Please use the same commissioning sequence as you would for a Grid-Connected system (to enable firmware updates).

Power the system up with just PV and battery (the inverter may show a 010 error initially, then go into backup mode) and update all the firmware (Dongle, Hybrid Inverter and Battery)

Off-Grid Settings

Log in via ‘Local Access’

Go to ‘Settings’ > ‘Energy Management Parameters’ > ‘General Parameters’ > ‘Energy Management Mode’ and enable ‘ MicroGrid System Mode’

Set the generator to auto-start or manual start

The generator can be set to either start/stop depending on battery SOC%, or manual start/stop. The 2-wire control cable must be connected for this function.

Go back to ‘Energy Management Parameters’ and select ‘MicroGrid System Parameters’

Set the ‘Nominal power of Genset’ and the ‘Maximum Permitted Charging Power from AC’ to suit the installation.

If using the SOC% method of generator control, set the lower and upper SOC%.

Or, the generator can be started and stopped manually via the ‘Forced Start’ and ‘Forced Stop’ function in the App.

__ Step 4: Testing the generator operation

Once all the settings are complete, set the generator to auto-start in accordance with the generator instructions.

Switch off the PV.

Ensure the battery is not 100% (or discharge to the low SOC% setting)

Start the generator and observe the system supplying loads and charging battery.

If using the ‘Forced Start’ method, select ‘Forced Stop’ to shut generator down.

If the issue still persists, please take photos testing on site and contact Sungrow Service Department on 1800 786 476 or email to service@sungrowpower.com.au.
