Installing the Inverter

Before installing the inverter ensure that the battery is properly installed. For more details refer to Battery Quick Installation Manual or Safety and Installation Instructions.
Electric Shock Hazard
Before doing any electrical connection, ensure the PV switch, AC and BAT circuit breaker are switched OFF and cannot be reactivated.

Electrical Connections

1. Installing the PE cable
   DANGER
   You must protect each inverter with an individual AC circuit breaker in order to ensure that the inverter can be disconnected safely

**Warning**
The max. allowable grid circuit breaker specification is 40A. At the same time, the cross section of the copper conductor for grid connection must be 6mm² (in some countries: 8mm²). You should use APP or Web monitoring to do the right setting, otherwise it would increase the danger of the circuit breaker tripping under normal operating conditions.

2. Connecting the Grid Power Cable
   

3. Connecting the AC Backup Power Cable
   

4. Connecting the BAT Power Cable
   ****| 1. Switch OFF the battery breaker which is located on the right side of the battery
   2. Connect the BAT – wire first (Black) then the BAT + wire (Red)|

DANGER
Danger to life due to short-circuiting of the battery
• Touching a shorted battery connection may result in lethal injuries due to electric shock and massive energy release.
• Switch off the battery breaker which is located on the lower lest of the inverter.
• Connect both ends of one battery power cable completely before connecting the next power cable to avoid short-circuiting of the positive and negative battery power cables.

Communication Connection

1. Wi-Fi module Connection
   

2. AUX / LAN/PV-CT Meter/DRM/GRID-CT Meter/RS485/BMS Connection
   Communication connection port as follows:

Install top cover

**Warning**
Before turning on power, ensure that all the electrical connections are secure.

Commissioning

To set up the inverter as part of a SunPower Reserve installation, follow the commissioning steps as outlined in the Reserve Safety and Installation Instructions.

Power ON / OFF the Product Procedure

**Warning**
Ensure a reliable and correct installation and electrical connection before power on.

Power ON procedure

1. Switch on the battery breaker of the batteries.
2. Switch on the battery breaker which is on the left side of the inverter.
3. Press the battery button, if there are more than one battery, the button for each battery should be pressed within 5s of previous.
4. Switch on the breaker between the grid port of the inverter and the grid.
5. Switch on the AC breaker between the backup port of the inverter and the loads.
6. Switch on the PV switch on the left side of the inverter.
7. Switch on the PV switch between the external PV-inverter and the grid if there is any.

Power OFF procedure

1. Switch off the AC breaker between the backup port of the inverter and the loads.
2. Switch off the PV switch is on the left side of the inverter.
3. Switch off the PV switch between the external PV-inverter and the grid if there is any.
4. Long press the power button of the battery pack for 6 seconds, then switch off the battery breaker of the battery pack.
5. Switch off the battery breaker which is on the left side of the inverter.
6. Switch off the AC breaker between the grid port of the inverter and the grid.
