Scope of Delivery

Inverter (RESERVE-INV-1-P5-L1-INT)

Additional Materials Required for Installation

Installation Tools

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.

Installing the inverter

DANGER

Electric Shock Hazard:
Bore doing any electrical connection, ensure the PV switch, AC and BAT circuit breaker are switched OFF and cannot be reactivated.

Electrical Connections

Installing the PE cable

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

Selecting a circuit breaker and copper cross-section
The maximum allowable grid circuit breaker specification is 50 A when the copper conductor cross section for grid connection is 10 mm2 and factors influencing the ampacity of the cable, other influences on dimensioning must be considered. You may use SunPower One installer dashboard to adjust the grid circuit breaker specification from 32A to 40A, otherwise the circuit breaker may trip under normal operation conditions.

Connecting the Grid Power Cable

Connecting the AC Backup Power Cable

1. Three-core (L, N and PE) outdoor copper cable Conductor cross-section: 4-6mm²

2. Insert the crimped conductors, L, N and PE into the corresponding terminals and tighten the screws (torque 1.5±0.1N-m)
   Assemble the locking cap, threaded sleeve and swivel nut together

3. Plug the connector into the socket and tighten firmly

Connecting the BAT Power Cable

CAUTION

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 left of the inverter.
• Connect both end of one battery power cable completely before connecting the next power cable to avoid short-circuiting of the positive and negative battery pwer cables.

Connecting the PV Power Cable

1. Strip off the insulation.

2. Assemble the MC4 cable ends.

3. Assemble the connectors.
   Please check if the cables are securely installed by pulling outwards.

4. Check the polarities of the PV strings. Check the open-circuit voltage is less than 580V.

5. Remove the waterproof caps.
   If there is a used terminal, please seal with the cap.

6. Insert the connectors into the terminal until an audible click is heard.
