Safety Instructions

• Follow all electrical safety standards and isolation procedures.
• Do not open or modify internal components.
• Use appropriate PPE and certified test equipment.
• Ensure the inverter is mounted securely before cabling.

Installation Steps

• Mount the wall bracket in a load-bearing location.
• Hang the inverter and secure using supplied locking clips.
• Maintain ventilation clearance as specified.
• Route AC and DC cabling through designated wire covers.

Connection Overview

• Battery: Connect using 16mm² (minimum) tri-rated DC cables.
• AC Grid: Connect via appropriate breaker and RCD protection.
• EPS Output: Connect essential loads (max 3000W) with 30mA RCD.
• Communications: USB/Wi-Fi/GPRS modules and CAN/RS485 ports as required.

EPS (Emergency Power Supply)

• Supports up to 3000W output for essential circuits.
• Requires overload protection up to 20A.
• Must be installed using approved EPS switching methods.

AC Utility Grid Connection

• Minimum 2.5mm² AC cable recommended.
• Breakers and RCDs must match installation load requirements.
• An earth rod must be installed at the supply origin.

Battery Connection

• Use 16mm² DC cables as a minimum.
• Gen 1 batteries require a DC MCB in-line.
• Compatible with both Gen 1 and Gen 2 GivEnergy batteries.

Commissioning

• Log in at portal.givenergy.cloud.
• Confirm the battery, inverter, and meter are detected.
• Configure battery parameters and operational settings.
• Verify meter communication and live data.

Start-Up Procedure

• Turn on AC supply.
• Turn on battery isolator.
• Allow inverter to boot and synchronise with grid.

Shut-Down Procedure

• Turn off AC isolator.
• Turn off battery isolator.
• Wait for inverter LEDs to fully power down.

Decommissioning

• Isolate all AC and DC supplies.
• Disconnect battery and communication cables.
• Remove inverter from wall bracket.
• Store in original packaging where possible.

Work Modes

• Eco Mode: Prioritises renewable and stored energy for self-consumption.
• Off-Peak Charging: Charges the battery during cheaper tariff periods.
• Backup / Island Mode: Supplies selected circuits during grid outages via EPS.
