This manual provides a full installation and configuration summary for the GivEnergy
Generation 1 Hybrid Inverter in 3.6 kW and 5.0 kW models. It consolidates all essential
information from the official installation manual, including safety requirements, mounting
instructions, AC/DC wiring guidance, battery compatibility, EPS setup, commissioning, and
shutdown procedures.
Product Overview
The Gen 1 Hybrid Inverter is a combined solar inverter and battery inverter, supporting
bi-directional operation. It can charge from solar (DC coupled) and from the grid (AC
coupled), while supplying the property and reducing both import and export through built-in
energy management. It is compatible with Gen 1 and Gen 2 GivEnergy batteries.

Connections Overview
- PV Input
- Battery DC terminals
- AC supply terminals
- EPS terminals
- PV isolation switch
- USB port (WiFi/4G module)
- RS485 / CT / BMS / DRM communication ports
AC Utility Grid Connection
The required AC cable sizes and protection depend on model:
| Model | Max Output Current | Breaker | Minimum Cable Size |
|---|
| HY 3.6 | 16.4 A | C20 | 2.5–4 mm² |
| HY 5.0 | 22.8 A | C25/C32 | 4–6 mm² |
EPS (Emergency Power Supply)
The EPS output supports up to 5000 W (model-dependent). It must be protected by a
30 mA RCD (up to 20 A) close to the inverter. Correct EPS wiring diagrams are shown in the
manual alongside examples of incorrect configurations.
Battery Connections
Gen 1 Battery (2.6 / 5.2 / 8.2 kWh)
- Use a ring-terminal to ring-terminal DC cable.
- Install a minimum 100 A DC MCB between battery and inverter.
Gen 2 Battery (9.5 kWh)
- Use ring-terminal to all-in-one plug cable.
- A DC MCB must be installed between Gen 2 and any additional Gen 1 batteries.
Connecting the MID Meter
- A MID-approved meter is required for grid import/export monitoring.
- Install CT clamp around incoming live cable with arrow pointing towards the property.
Communication Ports
- RS485 – meter or EMS
- CT terminal
- DRM input
- BMS (battery communication)
- USB (WiFi/4G dongle)
Start-Up Procedure
- Connect and switch on AC breaker.
- Turn on the PV isolation switch.
- Turn on the battery breaker.
- Turn on the battery.
- Inverter will start when PV voltage >150 V and battery >46.4 V.
Shutdown Procedure
- Turn off battery.
- Disconnect the battery breaker.
- Turn off PV switch.
- Open AC breaker.
- Wait for LEDs to turn off before working on the system.
Commissioning
All systems must be commissioned via the GivEnergy Portal. Log in at https://portal.givenergy.cloud using installer credentials. Set battery parameters correctly,
verify meter readings, and ensure communication is active.
Decommissioning
- Follow full shutdown process.
- Remove all AC/DC and communication cabling.
- Remove the inverter from the wall bracket.
- Remove the mounting bracket.
Storage & Packaging
- Store between -25°C and +60°C.
- Use original packaging where possible.
- If repacking, secure the inverter firmly with suitable supports.
Operating Modes
The Gen 1 Hybrid supports several operating modes:
- Eco Mode – Prioritises using solar and battery power to support the home.
- Off-Peak Charging / Peak Discharging – Uses tariff schedule for timed charging and discharging.
- Back-Up / Island Mode – Provides EPS output during grid failure when correctly wired.
Warranty
The Gen 1 Hybrid Inverter 3.6 kW & 5.0 kW is covered by a 12-year manufacturer warranty.
