Download Manual

This manual provides the installation, wiring, configuration, and safety guidance for the GivEnergy Gen 3 Hybrid Inverters in 3.6 kW and 5 kW models. It summarises the full installation manual and includes all required steps for mounting, AC/DC connection, commissioning, and safe operation.

Product Overview

The Gen 3 Hybrid Inverter combines a solar PV inverter with a battery inverter to enable solar generation, battery charging and discharging, and whole-home optimisation. The unit supports dual MPPT PV input, battery communication via CAN, and advanced monitoring through LAN, WiFi or 4G modules.

Specifications

Box Contents

• Hybrid Inverter (Gen 3)
• Mounting bracket
• Fixings pack
• Quick start guide & documentation

Installation Requirements

• Installation must be performed by a GivEnergy Approved Installer.
• Store between 5°C and 60°C before installation.
• Do not install in direct sunlight or enclosed cabinets.
• Ensure adequate ventilation around the heat sink.

Safety Instructions

• High-voltage DC and AC present even when powered down.
• Batteries must only be GivEnergy-approved LiFePO₄ storage units.
• Incorrect polarity will cause permanent inverter damage.
• Heat sink becomes hot during operation; avoid touching.
• Ensure protective earth (PE) is connected before energising.

Mounting the Inverter

Mount the inverter vertically with all cable glands facing downward. Use the wall bracket provided and ensure the wall is strong enough to support over 35 kg. Minimum clearances:

• Left: 300 mm
• Right: 300 mm
• Top: 300 mm
• Bottom: 500 mm

PV Connections

The inverter includes two independent MPPT trackers with one string per tracker.

• Max string current: 16 A
• Max input voltage: 600 V
• Start-up voltage: 80–100 V
• Ensure identical panel orientation and pitch per string.

Battery Connections

Gen 3 hybrid inverters use GivEnergy high-current DC battery connectors. Battery communication uses the CAN port (BMS → Inverter).

• Use Gen 2/Gen 3 plug-to-plug battery leads.
• Ensure BMS DIP switch addressing is correctly set.

AC Grid Connections

A double-pole isolator must be installed between inverter and consumer unit.

Communication Ports

• RS485 (for meter or EMS)
• CT input
• CAN (battery BMS)
• LAN port
• USB port (WiFi/4G dongle)

Commissioning

1. Power the inverter with AC.
2. Wait for the screen to initialise.
3. Confirm CT orientation and meter readings.
4. Register the system on portal.givenergy.cloud.
5. Perform firmware updates if prompted.

Start-Up Procedure

1. Close AC breaker.
2. Turn on DC switch.
3. Turn on PV switch.
4. Verify inverter enters normal operation.

Shutdown Procedure

1. Turn off PV isolator.
2. Turn off DC switch.
3. Open AC breaker.

Storage & Maintenance

• Store between -20°C and 60°C.
• Keep the heat sink free from dust accumulation.
• Check all cable glands annually.

Warranty

The Hybrid 3.6 kW & 5 kW Gen 3 models include a 12-year warranty.
